On September 23, 2014, Jeffrey Sachs presented the 2014 Pathways to Deep Decarbonization report at the “Economic Case for Action” session at the UN Climate Summit. The Summit, convened by UN Secretary General Ban Ki-moon, brought together world leaders, from government, finance, business, and civil society to galvanize climate action and build momentum towards a global agreement under UNFCCC at COP21 in December 2015.

Notes from the “Economic Case for Action” session are available here.
