4C Project Introduction
In the 4C project, we work to better understand how emissions affect atmospheric concentrations and lead to temperature rise. 4C will inform the Global Stocktake and help policy makers and governments take the appropriate measures to keep global warming below the Paris Agreement’s threshold of 2ºC.
