As Covid-19 continues to disrupt the world economic and political order, the global climate-change movement faces a choice: Learn the lessons of the pandemic or fail.
On the one hand, the lockdowns in response to Covid-19 led to the sharpest reduction in emissions on record, with 2020 global CO2 emissions projected to fall by nearly 8% compared with 2019, according to the International Energy Agency. According to the United Nations Environment Program, that tracks almost exactly with what’s needed. UNEP estimates that emissions will need to fall by 7.6% year after year from 2020 through 2030 if the world is to have any chance of keeping the average temperature from rising more than 1.5 degrees Celsius.
As environmentalist group Extinction Rebellion co-founder Clare Farrellwrote in April, “the things we were told we simply can’t change when we were on the streets last year are perfectly possible (necessary!) to change if we decide to prioritise. Coronavirus is showing us what’s possible, at least.”
Yet Ms. Farrell warned against premature celebrations. “People are using this crisis to celebrate the fall in emissions when the truth is, they will need to drop way more than coronavirus has caused them to if we’re to stand a chance.”
It’s actually even worse. Most of the measures that led to the drop in emissions aren’t economically sustainable. The economic damage inflicted by lockdowns has been so savage that political leaders around the world are pushing to reopen their economies as the pandemic continues to rage. It’s hard to imagine that countries would put themselves through this much disruption and pain to stave off future threats to the planet.
