Incorporating Air Quality Improvement at a Local Level into Climate Policy in the Transport Sector: A Case Study in Bandung City, Indonesia

Abstract

Climate policy has a strong influence on policy processes at national levels in Indonesia, while other policies with a focus on air quality improvement are being implemented at local levels. Indonesia as a developing country has committed to reducing greenhouse gas (GHG) emissions by 29 percent by the year 2030. This calls into question the extent to which cities and local governments can cope with the challenges of climate change mitigation. The purpose of the research is to find out the extent to which local air pollution reduction policies can contribute to the climate change mitigation program. The research design involved an empirical case study on governance and policy relevant to climate change efforts to lower GHG in Bandung City, Indonesia. The study evaluated the air quality improvement and the climate change mitigation programs using the actor-based framework of the Contextual Interaction Theory (CIT). The governance and stakeholder characteristic of climate change mitigation were also analysed using the structural context part of the CIT framework. The result shows that air quality improvement policy is implemented separately from climate policy; the latter operates at the national level and the former at the local level. By looking at the actor interaction analysis, the study concludes that a more holistic environmental policy approach would be more efficient at reducing local air pollution and contributing to the mitigation of climate change.

1. Introduction

Global climate change, environmental degradation, poverty, and the lack of availability of water and food due to population density pressures are factors that magnify disasters. These should be avoided, mitigated and thoroughly managed, particularly in developing countries [1,2,3]. Rapid population growth and broadening of human activities have had a detrimental effect on the climate because of anthropogenic emissions sources.

Transportation is one sector that emits greenhouse gases (GHGs) and contributes significantly to climate change and air pollution. Increasing motor vehicle use in cities, particularly in developing countries, increases fuel consumption and, thus, GHGs emissions. It is difficult to reduce these CO₂ emissions since so many primary economic activities rely on it. Worldwide, the transport sector contributes 26% of global CO₂ emissions and is one of the few sectors where emissions are still growing [4].

Another problem is air pollution. The latter primarily results from a steep increase in vehicle use. Every year, the number of vehicles in Bandung City (the third largest city in Indonesia) has increased 10–15%. Meanwhile the increase in road construction has been at 0.45% per year [5]. This has inevitably led to congestion in Bandung City [6,7]. This problem is exacerbated by a lack of green open spaces (±7.86% of the total Bandung City area—far less than the legally binding target of 30%) [8]. The transport sector is also responsible for rising health care costs and for a loss of general welfare [9]. Furthermore, economic loss attributable to traffic congestion [10] has reached 4.63 trillion rupiah per annum (equivalent to $US 0.4 billion) [11].

Other related problems are a lack of clarity in measuring GHG emissions (a potential reduction in each action) and a lack of information about co-benefits [12]. The co-benefits are defined as benefits to the local environment because of mitigation actions/adaptation in addressing global environmental change [13]. A lack of awareness and differences in the priority given to sectors are other barriers to promoting co-benefits [14].

Several concepts of global climate change and local air pollution control have received increased attention in academic literature, e.g., sustainable urban transportation [15,16]. Another approach, which deals simultaneously with both the global and the local problems, is the so-called co-benefits approach [17,18,19,20,21,22,23]. The concept of “Sustainable Cities” [24] also addresses how cities can govern better to cope with climate change and focus on enabling actual spatial transformation, rather than only institutional change [24,25]. In practice, low-carbon cities have been used as a concept to mitigate climate change in developed countries, particularly in household energy management [24,26]. The co-benefit approach is a suitable focus for action [18,27]. It could support an integrated program to develop and implement policies that simultaneously both contribute to lowering GHG emissions, while, at the same time, address local socioeconomic sustainability challenges.

In this paper, the main research question is how the role of governance becomes effective to incorporate air pollution control. The policy also benefits the reduction of GHG emissions mitigation in the transport sector of Bandung. It signals that local governments apparently give little attention to mitigating climate change, but do mitigate air pollution. The paper examines to what extent air pollution policies can contribute to climate change mitigation in Bandung City.

The paper is divided into five sections. The next section (Section 2) reviews the relevant literature on air pollution control that address climate change (mitigation) or low carbon governance by cities and on co-benefits. The theoretical aspects of the CIT (Contextual Interaction Theory) framework are presented in the third section. The CIT framework is used to analyse climate governance in the Bandung City transport sector case and analysed further on the structural context for governance analysis. The research design and methods are discussed in the fourth section. The fifth section presents the results of the Bandung City case study, together with a discussion of the results. The paper ends by drawing conclusions and making recommendations for future research.

2. Low-Carbon Transport Governance and Co-Benefits

The 1987 Brundtland Commission report introduced the concept of sustainable development. Here stakeholders have to collaborate to implement its principles in the cities [16]. The concept of sustainable development led to new concepts, including: sustainable transport [28], sustainable urban transport [16], environmentally sustainable transport [29], sustainable low carbon transport [30], sustainable cities [31], and co-benefits [32]. The concept of sustainable transportation is multi-dimensional and encompasses three areas: (1) implementing technology; (2) pricing and financing; and (3) integrated transport and land use planning [15,16,28]. Further research in policy implementation is necessary to understand how this concept was developed and integrated in the program of climate change mitigation in Indonesia.

Bulkeley [24] studied modes of governing in terms of the reduction of GHG emissions. A framework was used which was adapted from the UN Habitat report. There are seven modes of low carbon governance that cities use [24]: (1) municipal self-governance; (2) municipal provision; (3) municipal regulation; (4) municipal enabling (predominantly governed by the municipality); (5) non-state voluntary; (6) public-private provision and (7) non-state mobilization (private-sector actors). Governance approaches by local government include forms of self-governance (e.g., staff travel planning, vehicle fleet fuel switching based on local readiness), regulations (e.g., emissions standards, planning laws), provision (e.g., of public transport service or infrastructure for alternative modes of travel), enabling (e.g., information) and partnerships (e.g., public-private financing for new modes of transportation) [31].

According to Bulkeley et al. [31], there are four key motivations for climate policy and actions that local governments have: leadership, the stimulus from the central government to local governments, resources and issue framing. In terms of leadership, Bulkeley et al. [31] found that individual political ‘champions’, such as the Mayor of Yogyakarta, are important actors supporting advance initiatives (e.g., a program to retrofit lights and reduce air conditioning hours and bulbs, change travel behaviour, and developed BRT).

The stimulus of central governments (China and South Korea) has been a crucial factor in developing the political space (authority) for local government action on climate change (in public transport provision and street lighting). The available resources are also very important. This is exemplified in the Seoul case study illustrating the funds allocated for climate change action to finance research, technology development and mitigation schemes, to support renewable energy and also to improve energy accessibility and promote greater energy efficient [31].

Issue framing is considered a critical factor in climate change policy and action. First, it is important for energy security and fuel efficiency to help eradicate poverty. Second, framing low-carbon strategies in term of air quality and health problems have led to some initiative by local actors in the transport sector in all the case studies described in this paper.

In the Contextual Interaction Theory (CIT), Bressers [33] addresses motivation as a key actor characteristic that drives social interaction processes that the processes, in turn, reshape. However, resources are not part of the motivation, but are included as a variable of actor characteristics.

Most cities in Indonesia face considerable barriers to address climate change; notably in coordinating policy action, obtaining resources, operating in national level frameworks, which do not always facilitate local action [34], and in the often-conflicting aims of climate protection and economic growth [31]. Categories involving policies and mechanisms, cognitions and capacities have advantages and disadvantages. Other factors mentioned by Bulkeley [24] that are barriers and drivers of climate change mitigation efforts were institutional, political and socio-technical factors. The CIT framework treats these as the wider context and structural context, which will be presented in governance analysis framework.

The Concept of Co-Benefits

Local environmental issues—such as air quality, congestion and health—are primary issues for governments to deal with. Therefore, there have been several attempts by local government to overcome the problems. Various notions have emerged in the literature to define the concept of co-benefits. On the one hand, some approaches aim to tackle local environmental problems and overcome the global climate change problems at the same time. These often involve climate change mitigation efforts from several related sectors, such as transport, city planning, and the water, energy and health sectors [17,18,23]. This concept was developed in the Third Assessment Report (2001) by the Intergovernmental Panel on Climate Change (IPCC). This co-benefits concept also draws on the concept of environmental externalities [14].

Co-benefit approaches refer to the development and implementation of policies and strategies that simultaneously contribute to mitigating global change, while addressing local environmental issues and the impact on other developments. The CIT framework will analyse the co-benefits and actor characteristics. For developing countries struggling to deal with local problems, trying to implement climate change mitigation policy is often a step too far, which is why few cities in developing countries actually implement such policies [13,20,34]. Understanding the importance of governance in helping urban areas cope with climate change can provide useful lessons when designing tools for analysing and evaluating urban climate change programs.

3. Contextual Interaction Theory (CIT) Framework

This paper is intended to address how effectively the air quality policy has been implemented, using actor-based research. The research addresses the program instrument that also has the benefit of mitigating climate change. The literature suggests that implementing a policy model has developed from top-down [35,36,37], bottom-up [38,39,40] and synthesizers [41,42,43,44,45]. Differing views and methodological perspectives in policy research show the pivotal considerations of authority and legitimacy as to how implementation problems are learned. Rothstein [46] divided various government measures into operative conditions. According to O’Toole [47], the concept of governance emphasized understanding how well the multi-level character became an essential part of governance study. Other literature shows that the concept of governance is a broad one and is used in many ways (such as governance in a hollow state [48]; governance in the UN that more focuses in combating the shortcomings [49]; governing the commons as introduced by Ostrom [50]). Governance of climate change was introduced by Bulkeley et al. [31] in her research.

Eventually, the theory of implementation will lead to research about the actors, including research on how implementers and the target interact with each other and their motives, cognitions and resources. The Contextual Interaction Theory (CIT) from Bressers [33] can map actors’ characteristics in different layers. The interaction process maps relationships between the local level in Bandung City and other actors (both vertical and horizontal) and then divides them between various contexts (the wider context, structural context and specific context). The context based on actor interaction is influential in addressing climate change mitigation (Figure 1).

Research into the central role of actors (characteristics) to explain the interaction processes is crucial to CIT. It focuses on three core characteristics: motivation–cognitions–resources as defined by Bressers [51] and as a refinement of motivation, information and power. The structural context consists of elements of governance linked with relevant property and use rights. The wider context consists of elements of problem, political, economic, and cultural and the technological content (Figure 1). CIT was developed as a theory of implementation and has been used mainly in studies analysing policy in the environmental context and sustainable development, mostly in developed countries [52]. Lately, this framework has been more widely used in developing countries [53,54]. The implementer is the actor who is “officially commissioned to promote the envisaged measures”. The target is the “actor necessary to realize (the measures)”, such as citizens or companies [54].

Figure 1 is a schematic of how the interaction process occurs between actors. Various combinations of actor characteristics help describe the process of interaction between actors. This paper will assess how the regional and local levels of lowering GHG relate to the core characteristics defined in the red box where the dynamic process of actor interaction takes place. Knowing the core characteristics of the actors allows prediction and/or explanation of interaction processes in the implementation of certain projects [55].

4. Methods

This study will examine the transport sector and air pollution control in Bandung City and consider how the air quality improvement policies contribute to climate change mitigation. To address the main research question, case studies broken down into two consecutive phases were used. The first phase is descriptive of actors’ perspectives on local issues and programs, especially air quality programs and the contribution of these to climate change mitigation. The results are input in the second phase to help assess programs for their effectiveness when based on the actors’ estimation, interaction processes of actors, and other governance factors. The selection of actors considers actor objectives and responsibilities, and their perception of the other actors. All local level actors were chosen from the same region using the theoretical framework of which actors would be best.

4.1. Data Collection: Interview and Secondary Data

Data were gathered from a variety of sources. Primary data targeted the provincial level (as representative of the national level) and local level in the same region and used field interviews with people from the development planning agency, transport department, environmental and forestry, land use planning, and public transport. Secondary data comprised documents (policies and programs). Documents used included a climate change mitigation action plan, a midterm plan, a strategic plan, a working plan, a performance accountability report and a technical report on the current environmental status and the transport sector. Official statistics were used as much as possible. Data sources were triangulated to check for consistency. Where inconsistencies existed, estimates provided by knowledgeable local officials were used.

4.2. Data Analysis and Results

Data were analysed by use of Atlas.ti software by highlighting responses in each section of interest in order to build a narrative. Data were interpreted and grouped using Contextual Interaction Theory (e.g., the concept of actor characteristics of motivation, cognitions and resources). Using the Atlas.ti software simplified data analysis, especially in coding actor interpretations and perceptions of the programs. An example of such coding can be found in Section 4.2.4, where it is used to capture the Mayor’s motivations in the policy implementation process.

4.2.1. General Introduction to the Bandung Case Study

Bandung City is the capital of West Java (see Figure 2). It is the most densely populated province in Indonesia. Nowadays, it has become a metropolitan area called the Greater Bandung Metropolitan Area (BMA). Bandung is a core city of metropolitan areas surrounded by suburban areas that are municipalities (Bandung, West Bandung, Sumedang, Indonesia) and Cimahi City. The intensity of daily commuting in the hinterland of the four cities to core cities varies between morning and night. In 2010, Bandung’s population reached 2.5 million at night and 3 million people during the day [8]. In 2012, the total trips in the Greater Bandung Metropolitan area reached 3.57 million people per day and is expected to rise by 60% by 2020 (5.57 million people/day) [56].

Transportation problems in Bandung City appear when the capacity of the transportation infrastructure is unable to meet increasing travel demand. In 2009, there were 32 primary traffic congestion locations in Bandung City. These were caused by economic activities (e.g., street vendors, market places, paratransit—a minibus that has small capacity) and increased use of motorized transport (see

Table 1. The number of public and private vehicles based on type in Bandung City.

No.	Type of Vehicles	Quantity
1	Private motorcycle	1,030,729
2	Private car	318,598
3	Public bus transport	3166
4	Non-public bus	2181
5	Taxi	1856
6	Paratransit (angkot)	5521
	Total	1,362,051

). However, in 2013 the traffic congestion scattered in 44 locations [57].

Currently, 80% of the local road network capacity in Greater Bandung has reached saturation. The main public transport in core cities still relies on the paratransit and buses with limited routes and limited quantities, such as Bus Rapid Transit (BRT). Rail-based public transports serve only a small part of the travel demand (east–west path) and does not have the capacity to meet the increasing traffic demand. There are three main impacts of transportation in Bandung City (see

Table 2. Impact of transportation in Bandung City.

Economic Impact	Environmental Impact	Social Impact
Transportation costs in Bandung city US$ 33.5/month or equal to 22% of gross-expenditure (ideally no more than 20%) Total cost of transportation in Greater Bandung (2013) equal to US$1.42 billion / year (equal to 10.3% regional gross domestic product) and ideally no more than 7%	Contribute more than 66% of emissions of CO2 equivalent in Bandung City (motorized fuel consumption around 627 million litre/year) Land use change because of transport infrastructure in Bandung City (increase of length road is 1%; increase of vehicle number is 9% per year) Local air pollution (vehicles growth rate 12–21% per year)	Number of traffic accident increase 22 % per year Effect of congestion on physical and mental health increase (cannot be measured by local government)

).

Greater Bandung Metropolitan Area (BMA) has become a priority for the regional government (West Java Provincial). The focus is to manage the areas between Bandung city and surrounding cities, as mentioned in Governor Decree no. 70 year 2013. Managing Greater BMA is important not only for its economic development, but also for its transportation network and infrastructure. There are three classes of GHG emissions in Bandung City (see Figure 3). The energy and transport sectors are responsible for most emissions, particularly in the sub-sector of road transportation.

From guidance to lower GHG emissions as published by Bandung Environmental Management Agency (EMA), the strategies in the transport sector will also contribute to the reduction of the air pollution. The strategies are: (1) to avoid or reduce the number of trips that are not strictly necessary; (2) to shift to other environmentally friendly vehicles or forms of non-motorized transportation; and (3) and to improve efficiency of vehicles by improving vehicle technologies.

4.2.2. Chronology of Mitigation Events and Assessment of Core Characteristics of Bandung City Actors

This section presents the chronology of key events in climate change mitigation policy making in Bandung City. In Indonesia, the climate change mitigation effort, based on the National Action Plan on reducing GHG (RAN-GRK), as mentioned in the Presidential Decree No. 61 Year 2011, shows that the forestry sector and the peatland sector are the main sectors targeted for GHG emissions reduction (88.6% or equivalent to 0.672 Giga ton CO₂e) followed by waste management (6%), energy and transport (5%), agricultural (1%) and industry (0.13%). Although energy and transport come in third place, urban areas are the largest contributor of GHG emissions, especially in Java [59]. This indicates increasing GHG emissions in the transport sector as a major source in Bandung City (60% or 1394.98 Gg CO₂ equivalent from road transport). Transport is also the sector contributing the most to air pollution, particularly from the intensive use of motor vehicles 60–88% [8]. The air quality from roadside monitoring every year shows an increase (by 4–8 times) in the concentrations of hydrocarbon, PM₁₀ and CO (in particular PM₁₀ exceeded the WHO standard) [60].

After the Conference of Parties (COP) 15 in the Copenhagen Accord and G-20 Pittsburgh assembly, the Government of Indonesia (GoI) committed to reducing GHG emissions. This commitment is driven by top-down, rather than bottom-up strategies. Implementation challenges in developing countries that lack effective central regulatory regimes and plentiful budgets need the help of bottom-up analysts [61,62].

Three years after COP 15, the GoI developed a National Appropriate Mitigation Action (NAMA), which aims to implement actions below the national level. However, reducing GHG emissions from the transport sector, not only carried on by the central government, but also by designing and implementing a focus at local levels [63]. The NAMA development process in Indonesia also predominantly followed a top-down approach. The NAMA guidelines came from National Development Planning Agency (BAPENNAS) and it is embedded in national government policies, both mid-term and long-term. Provincial level governments were not involved in drafting the National GHG reduction plan (RAN-GRK). However, they were involved at a later stage when RAN-GRK was finished. Provincial level governments developed their own GHG reduction plans [34]. Moreover, the provincial plans also became guide for local level governments to mitigate climate change in the transport sector. In West Java, the provincial government compiled guidelines for achieving the regional GHG reduction plan that stipulated on Governor Decree No. 56 Year 2012 about RAD-GRK 2012–2020. It contains the baseline of GHG emissions, general descriptions of the emitters, as well as mitigation actions and suggestions on how to measure GHG emissions.

However, the provincial level government assumed that GHG reduction activities would be conducted at the local level of Bandung City. The provincial level and local levels hold different perspectives on the implementation of policy instruments (see Table 2) to lower GHG emissions. From the interviews with the stakeholders at the local level, it appears that no particular program for mitigation exists. The ongoing programs are acknowledged, as are environment and transport programs. Nonetheless, the Transportation Department states that several programs could potentially contribute to lowering GHG emissions (e.g., by CFD, traffic management, non-motorized transport, parking management, intelligent transport systems, and by monitoring of urban air quality). These findings may be an opportunity to promote climate change as a means to address local problems, as well as to mitigate climate change [25,64].

It is also known that, although supplemented by various guidelines from the national, regional and local levels, evidence of lowering GHG emissions in the transport sector is not visible. This is evident from annual local action plans in the transport department and EMA that lacked any action for mitigating climate change. This conclusion is also reinforced by the results of interviews with the local planning agency (Bappeda). This means that lowering GHG at the local level is not a top priority for local government compared to addressing local problems, such as traffic congestion, water pollution and waste reduction that appear as a more serious challenge in Bandung. This situation does depend on actor motives and their cognition in the consensus development plan. The consensus of development plan (musrenbang) is a mechanism dialogue between the parties (stakeholders) related to both direct and indirect benefits as a participatory approach to local development planning. Other reasons come from the local government perception of climate change. This is seen as simply a subset of a wider range of natural disasters, hazard risks, and domestic political pressures that undermine the international commitments to lowering GHG emissions in Indonesia [65].

However, an interesting approach came from the Mayor of Bandung. He has prioritized the development of thematic gardens to solving severe existing environmental problems (congestion, street vendors, waste, floods and transportation) ever since he was first elected. The aim of the Mayor’s policy is to increase the citizens’ level of happiness first, and then fix climate change problems later in a gradual manner. Beside the thematic garden, the Mayor also developed thematic days, which have become routine activities for Bandung citizens. Those contributing to climate change mitigation include: (1) bus rides to schools every Monday; (2) cycling on Fridays and (3) a Car-Free Day (CFD) on Sundays. The Institute for Global Environmental Strategies (IGES) initiated the workshop for stakeholders in Bandung in 2015 regarding the co-benefits of transport sectors. This workshop aimed to realise sustainable urban transport in Bandung City [66].

This form of leadership is one of four drivers for climate change policy and action by local government (as also mentioned by Bulkeley et al. [31]). Leadership attract other organizations to participate in climate policy. It shows that individual political ‘champions’ have an important role to play in supporting progressive initiatives. This also could help obtaining access to external funding that has been implemented in Bandung City in several programs (bike rental spots and Bandros (tourist bus)) which comes from Corporate Social Responsibility (CSR) funding.

The actors have estimated the contribution of the existing program to climate change mitigation. Some local government still needed to acknowledge the programs that contribute to GHG emissions reduction from its activities. Even though, EMA already found difficulties in gathering emissions data from all sectors. In line with the national target, local levels have to decrease their emissions by 2% per year. However, measuring emissions levels to obtain primary data proves to be very difficult. Until now, the process of auction for collecting the emissions data is failing because no one is capable to carry it out (do not meet the technical requirement).

Actors’ understanding about the mitigation context also came from their knowledge of other actors involved in reducing GHG emissions. The Environmental Management Agency, which is in charge of the air quality improvement program at the provincial and local levels, already knew that the transportation department has the most important role and authority to mitigate climate change and lower GHG emissions.

There are nine programs or policies that relate to the lowering of GHG emissions in the transport sector at the local and provincial levels (see also

). The strategy is based on the so-called ‘avoid-shift-improve’ paradigm. This is a framework for climate change mitigation of sustainable urban mobility that is generally used by GIZ and IGES [12].

However, GHG emissions monitoring does not support the existing policies. This practice is not in line with UNFCCC guidelines, which state that: “the effects of climate change mitigation actions should be documented in accordance with best methodologies and practices (fixed by multinational bodies, such as UNFCCC), and must be tractable and comparable in transparent ways” [67]. Firstly, in Bandung City, the existing measure aims at ensuring that emissions inventories are updated periodically (based on Presidential Decree No. 71 year 2011). Secondly, the measurement activity is to report the achievement in reducing GHG emissions based on potential GHG emissions from various sectors.

Therefore, the relevant municipal competencies and availabilities for taking emissions measurements in Bandung City need more attention. The authorities for collecting data in the transport sector are not clearly defined. The Local Transportation Department assumed that it was not their duty to measure GHG emissions and therefore face difficulties in measuring the emissions from their program (public transport). However, other local governments (EMA) conducted the emissions inventory, not necessarily for GHG emissions.

4.2.3. Overview of Key Stakeholders

The empirical study shows that the involvement of actors related with climate change mitigation in Bandung City depends on their interest in the issue and their power basis. Only a few actors in the transport sector have higher interest (Ministry of Transportation, Local Transport Department and Local EMA). Collaboration only existed in national and provincial levels, as mentioned in the aims of RAN-GRK. Even at the local level, some implemented their initial target of GHG reduction. Local governments can decide themselves to determine the activities according to their specific abilities and particular conditions.

4.2.4. Results of the Actor Interactions Analysis

The climate change mitigation already conducted at the local level is more focused on solid waste management and tree planting (greening). The local environmental management agency (EMA) acknowledges that their institution has to collect GHG emissions data in Bandung City, as required by central government. All stakeholders assumed that the greatest responsibility for mitigation lies with the local transport department. The dynamic actor interaction of local government actors can be seen in Figure 4.

The local transport department encourages the Car-Free Day (CFD) and Trans Metro Bandung (TMB) to lower GHG emissions. However, they lack adequate information and knowledge as to how these policies and the resulting reductions could be measured. They prioritize citizen comfort and reducing conflict between public transport modes (improvement public transport) rather than action to achieve climate change mitigation goals. The local transport department is aware that implementing other programs (such as those already in planning, like MRT and cable cars) requires resources that could not be afforded at the local level. However, all actors at the local level agreed that the leadership of Bandung Mayor created a positive atmosphere in providing public services in Bandung City.

It is also evident that the local level actors believe that the Mayor has the capability to influence other stakeholders, not only in Indonesia, but also from other countries interested in investing in Bandung City. There have been several flagship programs launched by the Mayor; some relate to reducing GHG emissions. The school bus programs, bicycle policies, and public transport use are programs to deal with climate change mitigation. However, challenges, such as a lack of resources for infrastructure, depend on available budgets (especially from the central government). These issues have made it difficult to implement this policy. This has led to problems, such as the dominance of motorized users in Bandung City and a lack of coordination with other regions and provinces.

Using the Contextual Interaction Theory to analyse motivations, cognitions and capacity and power as characteristics of local-level actors (see Figure 4) reveals how and why a policy is implemented in a certain manner. When analysed, the actor characteristics provide a way to understand where the actors are focusing, the opportunities available to them as well as identifying the threats that may influence the result of the implementation process. In this case, as has been discussed above, incorporating air pollution control with climate policy at the local level has been met with challenges that include focusing attention to managing conflict between the different actors rather than successfully promoting climate change mitigation. With regards to opportunities, the actors realise that funding through different avenues, especially CSR, could lead to successful policy implementation, but a lack of information (and knowledge), especially to measure the benefits of climate change mitigation, places them at a disadvantage.

5. Discussion

Despite the lack of actors who understand about air quality improvement in the transport sector and their mutual co-benefits in lowering GHG emissions, a possibility to synergize the local programs emerges from the local perspectives (municipality and provincial level). The paratransit, car-free day, vehicle emissions testing (validity test), and Trans Metro Bandung (Bus Rapid Transit) have received more attention from the public and the government. However, the role of external actors (the central government) in encouraging and supporting the local level to create positive conditions is required to create a synergy with the national goals.

Central government has a strong desire to reduce GHG emissions. However, the interest and the influence (power) to act separately among the actors, together with the lack of coordination and diverse perception of the issues, can complicate the achievement of national targets. These barriers are similar at the provincial and local levels.

Narrowing down to the local level, the positive motivations triggered by the leader of Bandung City, involving several flagship programs that promote sustainability, have been well received by the community. However, in terms of air quality improvement and climate policy, the stakeholders shared the same concerns over a lack of information and guidance on how to synergize the programs. The lack of information led to a conflict with the existing public transport. Political and financial support from the national government is the most crucial aspect to incorporating air pollution control with climate policy at the local level. This constraint will not have much influence if the cognition and motivational aspects are still weak.

6. Conclusions

This study has provided a preliminary assessment as to how existing programs could potentially address co-benefits. Besides air quality improvement, other benefits perceived by actors relate to health improvement, enhancing local economic, tourism attraction, and reducing congestion. Local actors’ motivation to deploy climate policies is based on their local priorities. Local actors are aware of their lack of resources to develop the infrastructure for public transport and for local government to adapt their programs in low-cost budgets. When addressing local problems, it will be necessary to ascertain and cross-check the policies in the wider context.

By using the transport sector in Bandung City as one of the examples in this paper, we have also highlighted the difficulties faced by actors at different levels of government in implementing climate change mitigation policies, as expected by international policy makers.

Acknowledgment of the local perspectives of air quality improvement and climate policy can provide Bandung with a diversity of policy options. The identification of the effectiveness of the programs by certain sectors also needs analysis by other implementers and target actors.
