the impact of these projects in terms of measurable greenhouse gas emissions’ reductions to
help close the emissions gap needed to meet the 2°C climate goal.

Renewable energy and energy efficiency in developing countries: contributions to reducing global emissions

As the Paris Agreement enters into force less than a year after its adoption, countries are preparing to implement their Nationally Determined Contributions (NDCs), developing plans to reach their targets. Renewable energy (RE) and energy efficiency (EE) initiatives are central pillars of these national plans and will be integral to countries’ ability to meet their commitments. This report evaluates the mitigation potential for 224 internationally-supported projects in developing countries.

Understanding NAZCA: Challenges and Future of the World's Largest Voluntary Climate Action Platform

In partnership with the French Energy and Environmental Management Agency (ADEME), Data-Driven Yale evaluates more than 11,000 climate actions have been pledged in the last several years alone. To gauge the broad array of global climate actions, the UN Framework Convention on Climate Change (UNFCCC) launched the Non-State Action Zone for Climate Action (NAZCA) platform in December 2014. NAZCA shows the vast scale of pledged and ongoing actions from non-state (e.g., companies, investors, and civil society organizations) and sub-national (e.g., cities and regions) actors. These actions range from emissions reduction pledges, commitments to renewable energy production, to setting internal carbon prices and to making investments in green bonds. This report gives an overview of NAZCA’s content, exploring the extent to which cities, regions, companies, investors, and civil society organizations are represented on the platform.
