Based on our analyses of five core energy sectors, 15 industry sub-sectors, and 11 cross-sector themes, we have developed two possible "states of the world" for 2050.
One is the consequence of business-as-usual practices and mindset. Shifts that are already underway will continue, but not accelerate dramatically to change direction. In this scenario, global CO2 emissions are projected to rise by 35 percent, to as much as 54 GT by 2050.
The other “state of the world” depicts what we’ve termed the “stretch case.” Here, we’ve prioritized solutions that promote decarbonization, but also reduce energy demand, increase efficiency, reduce cost or control risk. We’ve also made some assumptions based on what our analysis tells us is possible:
- Total energy consumption will peak between 2020 and 2030, before falling to a level of around 85 percent of the 2019 level by 2050;
- The share of final energy consumption would shift significantly toward electricity, increasing from 20 percent in 2019 to 45 percent by 2050;
- The shift away from coal and improvements in process efficiencies would improve the intensity of CO2 emissions from power generation by 90 percent;
- The share of renewables used in power generation would grow to as much as 91 percent by 2050.
These and other shifts have the potential to cut CO2 emissions by more than 40 GT in the power sector alone. This is what we believe is possible, realistic and within reach.
