BERLIN (AP) — Global energy-related carbon dioxide emissions rose slightly in December compared with the same month of 2019, indicating the sharp drop seen due to the pandemic was short-lived. Figures released Tuesday by the International Energy Agency show emissions from the production and use of oil, gas and coal were 2% higher in December 2020 than a year earlier. The Paris-based agency said a resurgence in economic activity coupled with a lack of clean energy policies mean many countries are now seeing higher emissions than before the coronavirus outbreak. Scientists have previously calculated that CO2 emissions fell by 7% during 2020 as people stayed home because of the pandemic. Carbon dioxide is the main greenhouse gas responsible for global warming.
