The world is on lockdown. So where are all the carbon emissions coming from?:

Excerpt from this story from Grist:
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.
Transportation makes up a little over 20 percent of global carbon dioxide emissions, according to the International Energy Agency. (In the United States, it makes up around 28 percent.) That’s a significant chunk, but it also means that even if all travel were completely carbon-free (imagine a renewable-powered, electrified train system, combined with personal EVs and battery-powered airplanes), there’d still be another 80 percent of fossil fuel emissions billowing into the skies.
So where are all those emissions coming from? For one thing, utilities are still generating roughly the same amount of electricity — even if more of it’s going to houses instead of workplaces. Electricity and heating combined account for over 40 percent of global emissions. Many people around the world rely on wood, coal, and natural gas to keep their homes warm and cook their food — and in most places, electricity isn’t so green either.
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.
Your personal “carbon footprint” matters… just not as much as you hoped.
