Southeast Asia’s green economy is poised to reach US$430 billion by 2030, with a growth of 8% to 9% per year, according to a report by Bain & Company and Standard Chartered.
In the Southeast Asia’s Green Economy Report 2026: The New Calculus, it was found that capital deployment is no longer guided by climate ambition alone, as energy security, economic growth, and delivery now weigh equally in the calculus that determines investment flows.
The report highlights that tracking capital flows now shows the clearest picture of where the green economy is growing, where conversion is failing, and what it will take to close the gap.
Meanwhile, it was also revealed that determining the full potential of green capital deployment in Southeast Asia relies on the development of a robust power grid, but grid investment has lagged demand growth.
The report says closing the power, grid and EV green capex deployment gap could unlock an additional US$80 billion by 2030, a 25% rise on the baseline.
According to Bain & Company and Standard Chartered, the mechanisms designed to bridge the transition, including blended finance, transition credits, and corporate clean energy procurement, have an essential role to play and are needed at greater scale.
The challenge has been on the ecosystems they require: first-of-a-kind projects need policy frameworks, bankable offtake structures, and infrastructure readiness to come together at the same time, in the same place, with the same counterparties.
The report poses that the work ahead is not just to deploy more catalytic capital, but to accelerate the alignment that allows it to take off.
