Which of the following G20 countries has shown a decreasing trend in the Greenhouse Gases emission, in the year 2022 ?

  • A.Brazil
  • B.China
  • C.India
  • D.Indonesia

Answer: A

The key gives Brazil.

Brazil's gross greenhouse gas emissions fell in 2022. The SEEG inventory put them at 2.3 billion tonnes of CO2 equivalent, 8% below 2021's 2.5 billion, mainly because deforestation in the Amazon fell and rains reduced the use of fossil-fuel power plants. Most of Brazil's emissions come from land-use change and agriculture, so a drop in deforestation moves the national total.

The other three rose in 2022. The EU's EDGAR inventory found that China, the United States and India increased their emissions over 2021, with India's the largest relative rise at 5%, and Indonesia's emissions also rose as coal use grew. Some energy-only CO2 estimates show a small fall for China, but on total greenhouse gases the rise holds.
