This document provides guidance for business and Government to fast track zero-carbon economic growth. With hundreds of businesses pursuing bold climate change solutions and countries updating national climate plans in advance of 2020, the opportunity for greater ambition abounds. More and more businesses are seeing opportunity in the zero-carbon economy and taking action on climate change. Governments must use this as a strong vote of confidence and advance ambitious policies that provide companies with the clarity and confidence they need to unlock further investments in climate solutions. This is the “ambition loop” — a positive feedback loop in which bold Government policies and private sector leadership reinforce each other, and together, take climate action to the next level.
