Which Kyoto Protocol mechanism allows Annex I nations to fund emission reduction projects in Non-Annex I nations for certified credits?
💡 Explanation:The Clean Development Mechanism (CDM) is one of the Kyoto Protocol's three flexible mechanisms. It allows industrialized countries (Annex I) with emission reduction commitments to invest in emission reduction projects in developing countries (Non-Annex I). In return, they receive Certified Emission Reduction (CER) credits, which they can use to meet their own emission targets. This promotes sustainable development in Non-Annex I countries while helping Annex I countries meet their commitments cost-effectively.
Distractors:
- Joint Implementation (JI) allows Annex I countries to trade Emission Reduction Units (ERUs) from projects in *another* Annex I country.
- Emissions Trading Scheme (ETS) allows Annex I countries to trade Assigned Amount Units (AAUs) among themselves.
- Global Stocktake (GST) is a process under the Paris Agreement (not Kyoto) to assess collective progress.

What is the defining characteristic of a renewable energy source?

While many are low-carbon or produce less waste, these are not their *defining* characteristics.
