Global Shutdown, Streets Free Of Cars, And CO2 Output Only Down 5.5% - Where's The Rest Coming From?
edestrians have taken over city streets, people have almost entirely stopped flying, skies are blue (even in Los Angeles!) for the first time in decades, and global CO2 emissions are on-track to drop by … about 5.5 percent.
Wait, what? Even with the global economy at a near-standstill, the best analysis suggests that the world is still on track to release 95 percent of the carbon dioxide emitted in a typical year, continuing to heat up the planet and driving climate change even as we’re stuck at home. A 5.5-percent drop in carbon dioxide emissions would still be the largest yearly change on record, beating out the financial crisis of 2008 and World War II. But it’s worth wondering: Where do all of those emissions come from? And if stopping most travel and transport isn’t enough to slow down climate change, what will be?
“I think the main issue is that people focus way, way too much on people’s personal footprints, and whether they fly or not, without really dealing with the structural things that really cause carbon dioxide levels to go up,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies in New York City.
EDIT
Manufacturing, construction, and other types of industry account for approximately 20 percent of CO2 emissions. Certain industrial processes like steel production and aluminum smelting use huge amounts of fossil fuels — and so far, Schmidt says, that type of production has mostly continued despite the pandemic. The reality is that emissions need to be cut by 7.6 percent every year to keep global warming from surpassing 1.5 degrees Celsius above pre-industrial levels — the threshold associated with the most dangerous climate threats — according to an analysis by the United Nations Environment Program. Even if the global lockdown and economic slump reduce emissions by 7.6 percent this year, emissions would have to fall even more the year after that. And the year after that. And so on.
