The OECD is working with Member and Partner countries as well as other international and regional organisations, to identify and evaluate economically efficient and socially responsible policy pathways to achieve net-zero emissions at the global, national and city/regional level. This work can draw on a rich set of OECD tools and expertise in policy advice across all relevant areas of government and sectors of the economy, to support countries for the significant policy reform required to achieve net-zero emissions by 2050.
