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. The International Energy Agency recently published a 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. The study 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. It also examines key uncertainties, such as the roles of bioenergy, carbon capture and behavioural changes in reaching net zero.
The webinar was the occasion to discuss the content of IEA Report on NetZeroby2050 with Laura Cozzi, IEA Chief Energy Modeller, who led the writing team.
