World Energy Outlook 2021
Against the backdrop of turbulent markets and a crucial meeting of the COP26 conference on climate change in Glasgow, the 2021 World Energy Outlook (WEO) provides an indispensable guide to the opportunities, benefits and risks ahead at this vital moment for clean energy transitions.
The WEO is the energy world’s most authoritative source of analysis and projections. This flagship publication of the IEA has appeared every year since 1998. Its objective data and dispassionate analysis provide critical insights into global energy supply and demand in different scenarios and the implications for energy security, climate targets and economic development.

Including fossil fuel methane emissions increasesthe gap to 14 gigatonnes of carbon‐dioxide equivalent (Gt CO2‐eq).
