In lower-income countries, there was no real slowdown in emissions between 20 compared with the previous two five-year periods. The study shows that the annual rate of emissions cuts must increase roughly tenfold from 160 million metric tons a year in high-income countries before the pandemic struck. The Global Carbon Project, a team of scientists from around the world, found that 64 countries had cut their emissions in the period between 20 compared with 2011 to 2015, but 150 countries showed an increase in emissions in the latter period.Ĭountries must urgently intensify their efforts to cut greenhouse gas emissions, said Le Quéré. The paper, published in the journal Nature Climate Change, shows that many of the world’s major economies were reducing their emissions before the pandemic. “When fossil fuel infrastructure is put into use again, there is a risk of a big rebound in emissions in 2021, as was seen in the wake of the global financial crisis in 2009.”
“Emissions were lower in 2020 as fossil fuel infrastructure was used less, not because infrastructure was closed down,” he said. Glen Peters, of the Center for International and Environmental Research (CICERO) in Norway, who co-authored the paper, said structural changes were needed to economies around the world to move away from fossil fuels and other high-carbon activities. “There is a real contradiction between what governments are saying they are doing to do, and what they are doing,” said Le Quéré. The study joins other research showing that the drastic fall in greenhouse gas emissions associated with the pandemic will have little impact on long-term climate goals, and may be followed by a swift rebound unless countries take rapid action to direct their economies away from fossil fuels. “Every strategy and every plan from every government must be consistent with tackling climate change.” It can’t be about one law or policy, it has to be put at the heart of all policy,” she said. “We have failed to understand in the past that we can’t have tackling climate change as a side issue.
Governments must prioritize climate action in their efforts to recover from the pandemic, she said. “We need a cut in emissions of about the size of the fall every two years, but by completely different methods,” she said. Since lockdowns were eased in many countries last year, there have been strong signs that emissions will rise again to above 2019 levels, severely damaging the prospects of fulfilling the Paris goals.Ĭorinne Le Quéré, lead author of the study, said the world stood at a crucial point as governments poured money into the global economy to cope with the impacts of the pandemic. Research published on Wednesday shows that countries were beginning to slow their rates of greenhouse gas emissions before the Covid-19 pandemic struck, but not to the levels needed to avert climate breakdown. Lockdowns around the world led to an unprecedented fall in emissions of about 7 percent in 2020, or about 2.6 billion metric tons of CO2, but reductions of between 1 billion and 2 billion metric tons are needed every year of the next decade to have a good chance of holding temperature rises to within 1.5 degrees Celsius or 2 degrees C of pre-industrial levels, as required by the Paris agreement. Carbon dioxide emissions must fall by the equivalent of a global lockdown roughly every two years for the next decade for the world to keep within safe limits of global heating, research has shown.
