Global CO2 emissions are returning to pre-health crisis levels

The Govt-19 epidemic, while not zero in the fight against climate change, will have minimal impact. Global emissions of carbon dioxide (CO)2It fell 5.4% in 2020, with locks and partial closure of the economy – the biggest drop since World War II. But they need to get closer to their levels before the health crisis this year (+ 4.9%). This emerges from the annual review of the Global Carbon Project, a consortium of about 100 scientists from 70 international laboratories working on the carbon cycle, the results of which were released on Thursday, November 4th. This is another warning to the 196 countries that met in the 26the United Nations Climate Conference in Glasgow.

“The world is not taking a path to reduce emissions. However, the longer we wait, the faster and harder their reduction will be to achieve carbon neutrality and ensure global warming. ” Philip Sias, director of research at the Laboratory of Climate and Environmental Sciences and one of the authors of the study, warns. In particular, according to researchers, an increase in emissions in 2022 cannot be ruled out if road and air transport return to pre-epidemic levels and coal use remains stable.

This study, should be Soon to be published in the magazine Earth system scientific data, Concludes that CO emissions2 Combustion of fossil fuels and industrial and cement works are expected to reach 34.4 billion tonnes in 2020 against 34.8 billion tonnes in 2021. Addition of emissions associated with deforestation and other changes in land use (such as deforestation) – Estimates are still uncertain – Total reserves 39 billion tonnes CO2 In 2020, 40% increase since 1990.

“Not enough investments”

Involved in strong resurgence: Increase in energy consumption driven by fossils. Coal is the primary source of CO2, Is experiencing strong growth (+ 6%) like gas, and both are expected to exceed the 2019 level. Oil consumption is only increasing, and is expected to be lower this year than before the Govt. “Renewable energy still represents a small part of global energy production. Philip Sias Note. They were fine during the health crisis, but their relative role in 2021 declined slightly. The war between fossil fuels and low carbon energy will be crucial for the future of emissions. “
