A new accounting of global climate action to reduce greenhouse gas emissions finds a broad spectrum of commitments from non-state and subnational actors with potential to support and ultimately outpace governments in their emissions reductions. The exhaustive review from UN Environment, released ahead of the Global Climate Action Summit (GCAS), highlights the crucial role of non-state actors in reducing emissions and reaching climate targets. Ranging from city, state and regional governments to companies, investors, higher education institutions and civil society organizations, non-state actors are increasingly committing to bold climate action. As most national governments continue to come up short on their promises for better climate policy as pledged in the Paris Agreement, these efforts are increasingly recognized as a key element to achieving global emissions goals. In total, the report finds these pledges represent a projected reduction of between 1.5 -2.2 gigatonnes of carbon dioxide equivalent (GtCO2e) by 2030.
