In the last 18 months there has been a greater than ever focus on voluntary carbon markets as a vital tool in addressing the significant gap between the goals of the Paris Agreement, the commitments made by countries and climate science. Collectively we need to reduce emissions by 50%, from 50Gt to, at most, 25Gt annually by 2030, to be on track to limit warming to 1.5° Celsius by the end of the century. Current commitments will lead to an increase of 16% to 56GT, meaning we will reach 1.5° by 2030. Voluntary action at scale can help close this gap in the short and medium term. However, to achieve this the Voluntary Carbon Market will have to evolve quickly, retaining its rigour whilst moving from a cottage industry to an investment grade market.
