The new Lab class will be announced in March

The call for ideas is now closed. The Lab will select six innovative climate finance ideas to develop in 2023.

Demo Day showcases climate finance opportunities

The Lab hosted a virtual Demo Day to present 2022’s instruments to potential investors, funders, and implementation partners. The Lab’s climate finance innovators pitched their ideas and answered questions from the audience.

New Financial Instruments Create $1 Billion in Climate Investments Opportunities

The Lab’s 2022 class leverages financial instruments such as guarantees, insurance, credit scoring, and other financial tools to increase the pipeline of bankable opportunities for challenging sectors like methane abatement, green steel, shrimp farming, sustainable housing, and more.

Lab portfolio surpasses USD 3 billion in sustainable investment

The Lab’s 55 climate finance solutions developed since 2014 have now mobilized more than USD 3 billion in sustainable investments in emerging economies.

The Global Innovation Lab for Climate Finance

Nations, businesses, and investors are working to move toward a low-carbon, climate resilient economy. Many of the measures underpinning this transition, including energy efficiency, renewable energy, sustainable transport, climate smart agriculture, and curbing deforestation, face specific barriers to attracting investment.

By identifying, developing, and supporting transformative sustainable finance ideas, the Lab aims to drive billions of dollars of private investment to the low-carbon economy.
