Southeast Asia has achieved remarkable economic growth and lifted millions out of poverty in recent decades. But this success has come at a cost. Biodiversity loss, pollution, and natural resource depletion threaten the prospects of future generations.

These trends can be reversed if the right policies are adopted. A new ADB report, “Advancing the Green Economy Transition in ASEAN,” makes the case for a green economy driven by investments that reduce emissions and pollution, enhance energy and resource efficiency, and protect natural capital—all while improving livelihoods.

The blog explains how the region will gain by becoming a greener economy, and how it can reach that goal.

1. What can ASEAN gain from transitioning to a green economy?

A green transition can unlock new growth engines. Emerging sectors such as renewable energy, sustainable agriculture, green manufacturing, electric mobility, and circular economy solutions—such as repairing, reusing, and recycling—offer significant value addition and export potential. It is estimated that by 2030 the green economy could generate up to $1 trillion annually across ASEAN through new markets, efficiency gains, and cost savings.

Green investments can generate millions of jobs across energy, construction, agriculture, services, and environmental management, while protecting livelihoods that depend on natural resources, which currently accounts for around 37% of employment in the ASEAN region.

It can deliver these benefits while protecting biodiversity, reducing emissions, and helping strengthen Southeast Asia’s resilience to more frequent and severe disasters triggered by natural hazards.

2. How can ASEAN countries accelerate the shift to a green economy, given they’re at different stages of development?

Countries can advance their green transition by adopting country-specific approaches that reflect varying income levels and institutional capacities. Countries in the region should cooperate closely so everyone benefits.

Advanced economies like Malaysia and Singapore can leverage their stronger fiscal systems and market readiness to scale clean energy, green finance, and low-carbon infrastructure. Rapidly developing economies such as Indonesia, the Philippines, Thailand, and Viet Nam can grow their industrial sectors sustainably by investing in cleaner transport, renewable power, and resource-efficient manufacturing. Developing economies such as Cambodia and the Lao People’s Democratic Republic can leapfrog directly to low carbon development by expanding renewables and protecting natural resources.

Regional cooperation is essential. Harmonized standards, cross-border projects, and coordinated skills development can reduce costs, mobilize private capital, and spread best practices across the region.

3. In which green sectors can the ASEAN region lead?

ASEAN has strong comparative advantages and leadership potential in several green sectors. Renewable energy—particularly solar, wind, hydropower, and geothermal—stands out, given the region’s abundant natural resources and the need to meet rapidly rising energy demand. Scaling clean energy can help deliver reliable and sustainable power while strengthening industrial competitiveness.

Southeast Asia can also lead in sustainable electric transport—including electric vehicle manufacturing, charging infrastructure, and public transport systems—by building on existing automotive supply chains and growing urban markets. Sustainable and regenerative agriculture also offers major opportunities, given that agriculture employs a large share of the region’s workforce and plays a critical role in food security and emissions reduction.

The circular economy—waste management, recycling, extended producer responsibility, and resource efficient manufacturing—can be a regional strength as ASEAN looks for ways to address rising materials use and pollution. Finally, ecotourism and nature-based solutions like mangroves and wetlands to manage floods while providing fish nurseries, can generate income while protecting ecosystems.

4. What kind of policies should Southeast Asian countries prioritize to attract green investments?

Southeast Asian countries need coherent, credible, and long-term policy frameworks to unlock green investments at scale. First, governments should strengthen market shaping policies that help nudge good behavior through the “polluter pays” principle, such as pollution caps and tradable permits and the gradual removal of fossil fuel subsidies. These instruments send clear price signals that make green investments more competitive and predictable.

Second, countries need to introduce policies that attract investment, such as renewable energy targets, feed-in tariffs, green public procurement, and roadmaps for the energy, transport, agriculture, and industry sectors. Stable regulations and transparent permit processes reduce investor risk and lower the cost of capital.

It’s also important to have green finance frameworks, including national green taxonomies which for example uses a traffic light system to categorize coal as red, energy efficiency as amber, and renewable energy as green. This can be complemented by sustainability disclosure requirements, green bonds, and blended finance mechanisms that attract private capital, especially for high risk or early-stage projects. Policies that support the development of skills useful in green industries are also critical to sustaining political and social support for green investments.

5. What are the biggest investment opportunities for the private sector?

There are several high impact investment opportunities for the private sector, driven by rising demand, policy momentum, and large financing gaps. Foremost is renewable energy, as ASEAN is expanding clean power to meet growing energy demand while reducing emissions. Investments in grid modernization, energy storage, and regional power connectivity create more opportunities. The private sector can also play a key role in sustainable transport, including electric vehicle manufacturing, charging infrastructure, and battery supply chains.

Sustainable and regenerative agriculture offers strong returns. Organic farming, for example, benefits from higher-income markets, while the use of technology such as drones and sensors can boost agricultural yields while reducing resource use and environmental impact. There are also growing opportunities in waste management, recycling, and resource-efficient manufacturing. Finally, green buildings and infrastructure offer scalable investment potential, supported by green standards and public procurement.

6. What kind of jobs can be generated in a green economy?

A green economy can generate a wide range of new or reskilled jobs. These include careers in solar, wind, hydropower, and geothermal installation, operation, and maintenance, as well as in grid management and energy efficiency. Sustainable agriculture and forestry can create employment and protect livelihoods that depend on natural resources.

The transition also generates jobs in green manufacturing, construction, transport, waste management, and circular economy activities. There are also emerging roles requiring green skills such as environmental management, digital solutions, and sustainability services.

7. How can governments ensure workers are not left behind in this transition?

Governments must invest heavily in reskilling and upskilling, particularly through technical and vocational education and training (TVET) systems aligned with sectors such as renewable energy, sustainable agriculture, and the circular economy. This helps workers from declining carbon-intensive industries to move into new opportunities.

Workers displaced during structural shifts need retraining subsidies and targeted employment programs to find new jobs. Governments must also strengthen unemployment benefits, income support, and transition assistance to cushion short-term adjustment costs and reduce the vulnerability of people whose jobs are affected by the transition.
