Concept of Carbon Trading is given in Options :Kyoto ProtocolMontreal ProtocolConvention on Biological DiversityAll of the above

Understanding Carbon Trading

Carbon trading is primarily related to the Kyoto Protocol, which is an international agreement aimed at reducing greenhouse gas emissions. The Kyoto Protocol established mechanisms such as emissions trading (also known as carbon trading) to allow countries to trade emission allowances in order to meet their greenhouse gas reduction targets.

Analyzing the Options

1. Kyoto Protocol: Yes, this is directly related to carbon trading.
2. Montreal Protocol: This treaty focuses on the protection of the ozone layer by phasing out the production of substances responsible for ozone depletion, not carbon trading.
3. Convention on Biological Diversity: This is related to the conservation of biodiversity, not carbon trading.
4. All of the above: Since only the Kyoto Protocol relates to carbon trading, this option is incorrect.

Conclusion

The correct answer is Kyoto Protocol, as it is the only option that pertains directly to the concept of carbon trading. The other two options do not relate to carbon trading mechanisms.
