The Climate Action Accelerator, a not-for-profit association, aims to mobilise a critical mass of community organisations in order to scale up climate solutions, contain global warming below 2°C and avoid the risk of dangerous runaway climate change. We support our partner organisations in driving rapid transformational processes to achieve the required level of global emissions reductions as soon as possible. Enabling them to work as a community, the Accelerator helps these organisations become champions within their own ecosystems and deliver valuable transformational change. This will contribute to a domino effect, for an exponential uptake and implementation of climate solutions across society.
