According to new knowledge from the International Energy Agency (IEA), world energy-related carbon dioxide emissions stopped rising in 2019: Global emissions have been unchanged at 33 gigatonnes in 2019 vs. 2018, even because the world financial system expanded by 2.9%.
The IEA says the flat determine was primarily as a result of declining emissions from electrical energy era in superior economies, due to the increasing function of renewable sources (primarily wind and solar), gasoline switching from coal to pure gasoline, and better nuclear power era. Other components included milder climate in a number of international locations, and slower financial progress in some rising markets.
“We now need to work hard to make sure that 2019 is remembered as a definitive peak in global emissions, not just another pause in growth,” says Dr. Fatih Birol, the IEA’s govt director. “We have the energy technologies to do this, and we have to make use of them all.”
A major lower in emissions in superior economies in 2019 offset continued progress elsewhere. The U.S. recorded the most important emissions decline on a rustic foundation, with a lower of 140 million tonnes, or 2.9%. U.S. emissions at the moment are down by virtually 1 gigatonne from their peak in 2000.
Emissions within the European Union fell by 160 million tonnes, or 5%, in 2019, pushed by reductions within the power sector. Natural gasoline produced extra electrical energy than coal for the primary time ever, whereas wind power practically caught up with coal-fired electrical energy.
Japan’s emissions fell by 45 million tonnes, or round 4% – the quickest tempo of decline since 2009 – as output from lately restarted nuclear reactors elevated.
Emissions in the remainder of the world grew by near 400 million tonnes in 2019, with virtually 80% of the rise coming from international locations in Asia the place coal-fired power era continued to rise.
Across superior economies, emissions from the power sector declined to ranges final seen within the late 1980s, when electrical energy demand was one-third decrease than at this time. Coal-fired power era in superior economies declined by practically 15% because of progress in renewables, coal-to-gas switching, an increase in nuclear power and weaker electrical energy demand.
“This welcome halt in emissions growth is grounds for optimism that we can tackle the climate challenge this decade,” Birol says. “It is evidence that clean energy transitions are underway – and it’s also a signal that we have the opportunity to meaningfully move the needle on emissions through more ambitious policies and investments.”
