One of the key pillars for reaching net-zero emissions is using energy more efficiently.

Our recent special report explores how the global energy sector can reach net-zero emissions by 2050. In the pathway it lays out – the Net-Zero Emissions by 2050 (NZE) Scenario – global energy demand in 2050 is around 8% lower than today but will need to serve an economy more than twice as big and a population with 2 billion more people.

That means each unit of energy will have to achieve more than it does today in terms of heating, cooling, cooking, moving people or things or powering a factory. Improving energy efficiency is a central foundation of a pathway that both meets the needs of a growing and increasingly wealthy global population, and achieves net-zero emissions by 2050.

Final energy demand in the NZE Scenario is well within the range of comparable 1.5 °C scenarios1 from the Intergovernmental Panel on Climate Change (IPCC), with many IPCC scenarios requiring similar or more ambitious energy efficiency improvements than the NZE Scenario. Total final energy consumption in 2050 in the IPCC scenarios ranges from 300 exajoules (EJ) to 550 EJ, compared with around 410 EJ in 2020. The NZE Scenario has final energy consumption of 340 EJ in 2050.
