The target for the first commitment period of the Kyoto Protocol is to reduce emissions of how many greenhouse gases by 5.2% from 1990 levels?

Correct option is A

The correct answer is (a) 6.
The Kyoto Protocol, which was adopted in 1997 and entered into force in 2005, set binding targets for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions. These targets amount to an average of five percent against 1990 levels over the five-year period from 2008 to 2012.
The Kyoto Protocol specifically covers six greenhouse gases:
1. Carbon dioxide (CO2)
2. Methane (CH4)
3. Nitrous oxide (N2O)
4. Hydrofluorocarbons (HFCs)
5. Perfluorocarbons (PFCs)
6. Sulfur hexafluoride (SF6)
These gases were chosen because they are the most significant in terms of their contribution to global warming and are largely produced by human activities. The target of a 5.2% reduction refers to the collective decrease in emissions of these six gases that the participating countries agreed to achieve, compared to their emissions levels in 1990.
