CO2 emissions from fossil fuels hit a record high, despite the blockade orders due to Covid-19
Global emissions from fossil fuels will increase by a record 6% in 2021, especially as the world remains heavily dependent on coal to recover from the economic crisis.
A significant decrease in CO2 emissions was recorded in early 2020 when the new Covid-19 pandemic broke out and brought economic and social activities to a halt. At that time, there were many expectations for a more sustainable economic recovery.
Indeed, renewable energy production posted its biggest growth ever last year, reaching a record high of more than 8,000 TWh. Combined with that, nuclear power still accounts for the majority of global electricity production.
But despite the strong growth of renewable energy, coal will still contribute greatly to the global CO2 emissions related to energy production in 2021. Specifically, electricity generation from coal. Rock has emitted about 36.3 billion tons of CO2, a record high ever.

The IEA reports up to 40% of growth in CO2 emissions has come from coal, accounting for an all-time high of 15.3 billion tonnes of CO2. Part of this is due to record-high natural gas prices, which have led countries to burn more coal to generate electricity.

Meanwhile, emissions from oil remain much lower than pre-pandemic levels as the economic crisis continues to affect the transportation sector until 2021, specifically the aviation sector.
According to the IEA, the increase in CO2 emissions is mainly due to China, which relies heavily on coal to meet its electricity demand, which will increase by 10% in 2021. The 700TWh increase in demand is the largest increase ever. of this country. According to IEA calculations, China’s total emissions will exceed 11.9 billion tons of CO2 in 2021, accounting for 33% of total global emissions.
In return, China also has the largest increase in renewable electricity production ever in 2021.
Although we have seen global CO2 emissions fall during the pandemic, concentrations of greenhouse gases in the atmosphere continue to rise.
Record increases were seen in the early stages of the pandemic in 2020 and again in 2021. This suggests that the decline in CO2 emissions was transient and did not contribute to slowing the trend. this. Meanwhile, strong greenhouse gas emissions such as methane continue to increase.
The IEA said in a statement: “The world must now ensure that the global recovery in emissions in 2021 is a one-off, and that a rapid energy transition contributes to global energy security and lowers energy prices for people.” consumption”.
