Some 33 US states have cut CO2 emissions while growing their economies over the past 15 years, according to new analysis from the Brookings Institution.
These states show that economic growth can be compatible with tackling climate change. The US as a whole is one of at least 35 countries around the world to have achieved the same feat, by decoupling GDP growth and CO2 emissions between 2000 and 2014.
“This success is an encouraging juncture in the campaign to limit global warming, and would seem to license cautious optimism,” write Devashree Saha and Mark Muro, the authors of the new research from the Brookings Institution’s Metropolitan Policy Program.
“Yet now all of that is in question. With the stunning election of Donald Trump to the presidency, every aspect of the low-carbon paradigm for national and world progress has been thrown into doubt.”
If the US federal government turns its back on climate mitigation, can individual sub-national bodies step up their own efforts? The authors explain:
“Given their substantial powers to encourage emissions decoupling, states and cities are crucial players in the carbon drama. Therefore, it is worth assessing whether states’ and localities’ momentum on decoupling is strong enough to maintain recent progress.”
