Carbon Emissions Dropped 17 Percent Globally Amid Coronavirus (nbcnews.com) 86

An anonymous reader quotes a report from NBC News: The coronavirus pandemic has forced countries around the world to enact strict lockdowns, seal borders and scale back economic activities. Now, an analysis published Tuesday finds that these measures contributed to an estimated 17 percent decline in daily global carbon dioxide emissions compared to daily global averages from 2019. It's a worldwide drop that scientists say could be the largest in recorded history. At the height of coronavirus confinements in early April, daily carbon dioxide emissions around the world decreased by roughly 18.7 million tons compared to average daily emissions last year, falling to levels that were last observed in 2006, according to the new study, published in the journal Nature Climate Change.

Drastic changes in transportation, industrial activities and air travel in nations under lockdowns could also fuel a decrease in this year's annual carbon emissions of up to 7 percent, the study found. Though significant, scientists say these declines are unlikely to have a long-term impact once countries return to normal unless governments prioritize investments and infrastructure to reduce harmful emissions. "Globally, we haven't seen a drop this big ever, and at the yearly level, you would have to go back to World War II to see such a big drop in emissions," said Corinne Le Quere, a professor of climate change science at the University of East Anglia in the U.K., and the study's lead author. "But this is not the way to tackle climate change -- it's not going to happen by forcing behavior changes on people. We need to tackle it by helping people move to more sustainable ways of living."
The sharpest decline in carbon emissions came from reduced traffic from cars, buses and trucks, which made up 43 percent of the total decrease. Although emissions from air travel fell by 60 percent, it made up a much smaller portion of the overall decreases because air travel typically accounts for only 2.8 percent of yearly global carbon emissions.

          I love my EV, and I built a driveway ($6,000) specifically to get one, but to pretend that the only cost for people to get one is the vehicle itself (and not a particularly cheap used one) is disingenuous. If I had a more serious daily commute, I'd need to install a level 2 charger, with a pretty long run from the electrical box. I'm taking it on faith I wouldn't need to upgrade my service (I have 150 amp I think, and all gas appliances, but for a circuit of baseboard heaters in an addition), but realistica
          • Also, that gets me 1 spot to charge, if it was a 2 car house, then the level 2 would be pretty much manditory.

            That doesn't follow. Whether you can get by with L1 charging depends on how far each car has to drive, not how many cars you have. If you're a two-car family and each vehicle drives little enough that you can recharge with 8-10 hours of L1, then your easiest solution is to use to L1 chargers, plugged into standard house outlets on different circuits.

            If one or more of the vehicles drives far enough that you can't reliably top it up with L1 then you need an L2 charger. Or two. But I think you're overesti

        By buying an EV, you are making your fuel source interchangeable without having to buy a different car... or in fact do much at all. And more and more electricity comes from renewables these days.

          • What are you talking about? I wrote, "switching more people to using EVs and while migrating to non-poluting power generation systems". The point is to switch to non-polluting systems from our existing polluting systems. This goes from top to bottom and each component has to be changed independently. Why would you think that any part of it must not be changed? Please quote the specific text because you really got me at a loss.

      It is not great at all. Because 17% is about a sixth less -- for the time. We are in the pandemic now for about three months, and that means, that we postponed the crossing of the point of no return just for about two weeks.

      The real question is "do people care or are they still egocentric assholes?"

      I can think of no better illustration of the progressive position, and their condescending, ignorant, self-righteousness than the statement above. If the poster above could show the average American making just $25k annually how they could afford an EV, and how they would save money by doing so, we'd be well on our way to solving the climate change issue. Better yet, if they could convince businesses to allow remote work for the majority of their workforce, we'd be better off still.

      But, good luck convincing your progressive brethren to go along. If progressives were serious about climate change, Google - one of the most progressive companies today - wouldn't have a campus. But alas, being progressive isn't about actual change, but rather, having the right thoughts and intentions, so you can believe yourself superior to others.

      • I can think of no better illustration of the progressive position, and their condescending, ignorant, self-righteousness than the statement above.

        This has nothing to do with political ideology because almost all of you are egocentric assholes. Only 1% of cars are EVs because it's a human problem, not a political problem.

        Nah, I'm pissed off that people like you, the people who could buy an EV still refuse to do so purely for selfish reasons.

    I recall reading about archaeologists using a similar effect to help in dating layers of dirt. Logic goes: we know when big plagues were. They wreck the economy. That stops silver mining/smelting, since who needs cash when you're all just bodies on the burn pile? So, if you've got dirt layers with a gap in the amount of smelting gunk, good shot it's from that plague time.

    This is the portion that is feasible to continue post-pandemic.

    There is no reason why everyone needs to work in the same office 5 days week. Even if we only let 60% of people work remotely 80% of the time, we can have 20% decrease of CO2 emission permanently, and that is quite an achievement.

    • You're assume the world is run out of offices. It's not. When the economy picks up a whole world of new sources of emissions rise again, eventually people need to do actual work "in the field", be that field a shop, a service, a construction site, a delivery.

    An alternative take I read somewhere that I thought was kinda interesting was that even with everyone working from home and huge chunks of the economy down, we were only able to move the needle 17%.

    I thought this was pretty interesting, because it highlights that even with the average citizen doing pretty much all they can (staying at home, no commute for work, no visiting friends, no flying around the world on holidays) and a lot of companies doing the same - despite that huge staggering effort put in by average people - the most it dropped was 17%.

    The interpretation of this was that, if this is the most that citizens can do if we all collectively do almost the absolute maximum, then it is not really very much, so (in addition to people doing what they can) we also need pressure on whatever it is that is accounting for the other 83% that has been cheerfully ticking over while all this has been happening.

      That's because we have one needle. My petrol usage is down 100% in the past two months. My electricity usage is up 250%, my gas usage up about 30% (it's getting warm so the heaters were only on for the first 2 weeks of COVID). I recycled a car battery that would likely still have been good had I not used the car, emissions indirectly are there too. I've supplemented side trips on the way home with ordering delivery (including the car battery). I still eat and crap so that needle hasn't changed.
