COVID-19 crisis sees global carbon emissions plummet by 17 per cent

COVID-19 crisis sees global carbon emissions plummet by 17 per cent”

For context, the Washington Post notes that a United Nations report last year said emissions must fall 7.6% a year starting in 2020 to avoid the worst effects of a warming climate.

A study published Tuesday in the journal Nature Climate Change reveals that global carbon emissions per day in April were 17 percent lower than the average daily emissions in 2019.

The study centered on 69 countries, all 50 USA states and 30 Chinese provinces, which account for 85% of the world population and 97% of all global carbon dioxide emissions.

Total emissions from industry and energy past year came to a record 37 billion tonnes. This most recent study found that, not only did NO2 emissions drop, but so did CO2.

The accord will see the council partner with stakeholders across Hamilton to reduce carbon emissions generated within the city. "That's just not the way that we want to do it", said Glen Peters, research director of the Centre for International Climate and Environmental Research in Oslo, and a co-author of the study. "But we know we can do it". A 60 per cent fall in aviation activity in April, compared to the same time a year ago, saw emissions fall by 1.7 million tonnes.

Before the Covid-19 pandemic triggered worldwide restrictions on movement, global greenhouse gas emissions have been increasing steadily year on year. Annual CO₂ pollution was stable in 2018 and 2019, approaching 37 billion metric tons.

In China, the decrease peaked at 24 per cent, India at 26 per cent, Indonesia 18 per cent and Italy 28 per cent.

As Covid-19 spreads around the world, it can be daunting keeping up with the information.

The researchers at the Global Carbon Project analyzed daily economic activity in 69 countries from January through April and modeled the carbon pollution that likely resulted, then compared it to previous year.

The analysis also shows that social responses alone, without increases in wellbeing and/or supporting infrastructure, will not drive the deep and sustained reductions needed to reach net zero emissions. Those changes may translate into long-term cuts in emissions, but that's likely not going to be enough.

But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be "a drop in the ocean" when it comes to climate change, scientists said.

The paper details how the restrictions have seen daily global greenhouse gas emissions fall by as as much as 17 per cent in April, compared to the same time past year.

Favoured tactics among some climate activists, such as "flight-shaming" popularized by Greta Thunberg, may be less effective.

"Across other sectors, the power sector ranked second and the industry sector (encompassing manufacturing and material productions) third in terms of their contributions to the global decrease in emissions in early April", Dr Canadell added.

They created a confinement index based on the severity of pandemic policies - 0 represents no policy, and 3 represents a maximum lockdown with stay-at-home orders and a shuttered economy.

"These investments go some way to helping us achieve our climate change goals, however our concern is this Budget does not take us far enough", said the letter.
