This report is the output of a review and consultation on responsible corporate engagement in climate policy, undertaken by the UN Global Compact in cooperation with UNEP, UNFCCC, WRI, CDP, WWF, Ceres and The Climate Group. It sets guidelines for why and how companies can provide constructive influences on public policy. The report is designed to help companies inform and accelerate the policies most urgently needed to support a stable global economy. It is also designed to help businesses engage in the political progress on reducing carbon dioxide and other greenhouse gas emissions, and adapt to disruptions in the global climate system. Five core elements of responsible policy engagement in climate policy are presented: legitimacy, opportunity, consistency, accountability, and transparency. These translate to three practical actions responsible companies can undertake around climate policy, which are: identify, align, report.
