Net Zero by 2050
A Roadmap for the Global Energy Sector
The number of countries announcing pledges to achieve net-zero emissions over the
coming decades continues to grow. But the pledges by governments to date – even if
fully achieved – fall well short of what is required to bring global energy-related
carbon dioxide emissions to net zero by 2050 and give the world an even chance of
limiting the global temperature rise to 1.5 °C.
This special report is the world’s first comprehensive study of how to transition
to a net zero energy system by 2050 while ensuring stable and affordable energy supplies,
providing universal energy access, and enabling robust economic growth. It sets out
a cost-effective and economically productive pathway, resulting in a clean, dynamic
and resilient energy economy dominated by renewables like solar and wind instead of
fossil fuels. The report also examines key uncertainties, such as the roles of bioenergy,
carbon capture and behavioural changes in reaching net zero.
