The South East Asia Clean Energy Facility (SEACEF) is managed by Singapore-based Clime Capital, with an initial investment of $10 million and a focus on getting new projects underway in Vietnam, Indonesia and the Philippines.

"We need to mobilize billions to make a meaningful impact on climate change," said Mason Wallick, Clime Capital’s managing director, who sits on the SEACEF investment committee.

Money is most needed to fill a gap in funding to help early-stage projects get off the ground, he added.

Asia-Pacific, home to two-thirds of the world’s people, is experiencing rising urbanization, population and economic growth, leaving nations scrambling to provide enough electric power while keeping promises to cut heat-trapping emissions.

Last year, researchers said Southeast Asian countries must end their reliance on coal power and switch to clean energy, to meet pledges to curb climate change and tackle air pollution.

But the region is struggling to wean itself off abundant, locally produced cheap coal in favor of clean alternatives to burning fossil fuels, the main contributor to climate change.

"Here in Southeast Asia, we have the equivalent of a China in terms of potential emissions," said Wallick.

"It’s a big market that should be coming up the curve in a more meaningful way to promote renewables now that (they are) economic and can fit within the (power) supply plans for these countries," he told the Thomson Reuters Foundation.

China is today the world’s biggest emitter of greenhouse gases blamed for global warming.

SEACEF describes itself as a "first-of-its-kind" philanthropic initiative to tackle climate change, focused on the high-risk funding needed to get new clean energy projects up and running.

It will look to invest broadly in projects and businesses that include wind and solar power, mains grid infrastructure, energy efficiency in buildings, and electronic mobility and storage, Wallick said.

Early-stage capital is "in very short supply," a situation exacerbated by the coronavirus pandemic pushing investors to reduce their exposure and limit development budgets, he added.

The fund, which hopes to attract an additional $40 million in capital from foundations and development banks, aims to mobilize more than $2.5 billion in clean energy investment from the private sector.

So far it is backed by Sea Change Foundation International, Wellspring Climate Initiative, High Tide Foundation, Grantham Foundation, Bloomberg Philanthropies, Packard Foundation and Children’s Investment Fund Foundation (CIFF).

"The launch of this new fund comes at a critical moment, with the Covid-19 crisis shrinking traditional sources of finance, dedicated towards bending the curve of climate change," said Imraan Mohammed, head of impact investing at CIFF.

Philanthropic organizations and impact investors are "stepping up to bridge the gap, catalyze other sources of funding and ensure the transition to clean energy in Southeast Asia continues to accelerate," he added in a statement.
