This report elaborated by NewClimate Institute with support from Climate Action Network (CAN) and the Global Call for Climate Action (GCCA), investigates the co-benefits associated with countries' Intended Nationally Determined Contributions (INDCs). This report first provides an overview of the general co-benefits that climate action may have and how they could be used to incentivise further ambitious greenhouse gas (GHG) reductions. We then provide illustrative results for the cobenefits achieved by the INDCs of the U.S., China, the EU, Canada, Japan, India, South Africa and Chile, as well as an indication of the forgone or missed benefits that could have been achieved through action that leads to 100% renewable energy in 2050.
