Toronto Atmospheric Fund, also known as The Atmospheric Fund, is a regional climate funder that supports high-impact solutions to reduce greenhouse gas emissions and air pollution in the Greater Toronto and Hamilton Area. Its grants focus on low-carbon buildings, electricity grid decarbonization, clean transportation, climate policy, scalable demonstrations and equitable urban climate benefits. In the funding ecosystem, TAF is important because it combines grantmaking with impact investing, research, policy influence and partnerships, helping promising climate ideas move from concept to evidence and from pilot to broader adoption. Its expression-of-interest and full application process gives non-profits, municipalities, charities and selected partners a structured path to test climate solutions, de-risk implementation and generate public benefits beyond a single project.
