An Updated Roadmap to Net Zero Emissions by 2050

Kategori : ELECTRICITY ENERGY NEWS, ENERGY AGENDA NEWS, ENERGY EFFICIENCY NEWS - Tarih : 02 November 2022


In 2021, the IEA published its Net Zero by 2050: A Roadmap for the Global Energy Sector, which sets out a narrow but achievable pathway for the global energy sector to reach net zero emissions by 2050. However, much has changed in the short time since that report was published.

The global economy rebounded at record speed in 2021 from the COVID-19 pandemic, with GDP growth reaching 5.9%. As energy intensity improvements stalled, global energy demand increased by 5.4%. Surging energy demand was in part met by increased use of coal, resulting in a 1.9 gigatonnes (Gt) jump in emissions in 2021, the largest annual increase in global CO2 emissions from the energy sector ever recorded.

This brought total CO2 emissions from the energy sector to 36.6 Gt in 2021. Recent investment in fossil fuel infrastructure not included in the 2021 Net Zero Emissions by 2050 Scenario would result in 25 Gt of emissions if run to the end of its lifetime (around 5% of the remaining carbon budget for 1.5 °C). At the same time, 2021 also saw renewables-based electricity generation reach an all-time high, a record more than 500 terawatt-hours (TWh) above the level in 2020.
