Renewable energy and energy efficiency projects in developing countries can go a long way to making up shortfalls in Paris climate pledges, while delivering huge human health and economic benefits, according to a new report by the 1 Gigaton Coalition. Renewable Energy and Energy Efficiency in Developing Countries: Contributions to Reducing Global Emissions finds that internationally supported projects, implemented in developing countries between 2005 and 2016, could reduce 0.6 gigatonnes of carbon dioxide equivalent (GtCO2e) from annual emissions by 2020. One gigatonne is roughly equivalent to a year of transport emissions in the European Union (including aviation).
