On Key Power Sector Metrics, World Progressing Too Slowly to Meet Carbon Reduction Goals, Report Finds
In order to limit global warming to an average of 1.5 degrees Celsius compared to pre-industrial levels, the world will have to accelerate its transition to using renewables in the power sector dramatically, a new report has found. Three power sector benchmarks are among 21 indicators researchers used to measure economy-wide progress on carbon reduction goals, which also span the buildings, industry, transport, agriculture and forest sectors.
Released Thursday by the World Resources Institute and ClimateWorks Foundation, the “State of Climate Action” report finds that the rate of progress in just two of these metrics — crop yields and ruminant meat (largely beef) consumption — has been fast enough historically to meet 2030 and 2050 carbon reduction goals.
In most of the others, progress is being made but not quickly enough to meet the benchmarks, and in two cases the world is heading in the wrong direction entirely. In four cases, the data is too limited to draw a conclusion.
Researchers used three indicators to track carbon reduction progress in the power sector: share of renewables, share of unabated coal and overall carbon intensity of electricity generation.
The report envisions the power sector using between 55 percent and 90 percent renewables by 2030 and 100 percent renewables by 2050, and simultaneously lowering its use of coal to between 0 percent and 2.5 percent by 2030 and to 0 percent by 2050. The report cited International Energy Agency data indicating that renewables made up 25.3 percent of global electricity generation and unabated coal made up 38 percent in 2018.
And the global emissions intensity of electricity generation will need to dip below zero by 2050, but the world has “not seen much progress toward this target in the last 30 years.”
Despite the lack of rapid advancement so far, the researchers say reason for hope remains.
“History has shown that transformative change can happen at an exponential, nonlinear rate; just look at how quickly cars, phones, and connected computers revolutionized our world,” they wrote. “We should consider this next decade as our decisive decade to change our course to arrive at a different low-carbon future by midcentury.
