1. Kyoto protocol came into force in the year 2005.
2. Kyoto protocol deals primarily with the depletion of the ozone layer.
3. Methane as a greenhouse gas is more harmful than carbon dioxide.
Which of the statements given above is/are correct?
Explanation
The Kyoto Protocol is an international treaty that commits industrialized nations to reducing greenhouse gas emissions (the third Conference of the Parties) in 1997 in Kyoto, Japan.
Statement 1 is correct: The Kyoto Protocol officially came into force on February 16, 2005.
Statement 2 is incorrect: The Kyoto Protocol primarily focuses on reducing greenhouse gas emissions to combat climate change, not on the depletion of the ozone layer. The ozone layer issue is addressed by the Montreal Protocol, which focuses on phasing out substances that deplete the ozone layer.
Statement 3 is correct: Methane (CH₄) is a more potent green-house gas than carbon dioxide (CO₂) in the short term. Although CO₂ persists longer in the atmosphere, methane has a much higher global warming potential over a 20-year period--about 84 times more potent than CO₂.
