Data are compiled by REN21 and based on CDP-ICLEI Unified Reporting System, CDP Open Data, The Global 100% Renewable Energy Platform, Climate Action Network, ICLEI, C40, IRENA, Sierra Club, UK100 and REN21 data collection.

City-level targets for renewables are listed unless otherwise noted. Deloitte, “Smart Renewable Cities”, from https://www2.deloitte.com/content/dam/insights/us/articles/4971_Smart-renewable-cities/DI_Smart-renewable-cities.pdf. It identifies and classifies cities globally that are deploying solar and/or wind power in connection with their smart city plans. This requires that cities have a publicly available city plan that presents a vision integrating renewables and smart city initiatives. In addition, the city must have already deployed solar and/or wind power (at least 1% of its energy mix) and plan to deploy more.
