One carbon credit is accepted as equivalent to
- A.100 kg of carbon
- B.100 kg of carbon dioxide
- C.1000 kg of carbon
- D.1000 kg of carbon dioxide
Correct answer
Explanation
The correct answer is D, 1000 kg of carbon dioxide. One carbon credit stands for one tonne of carbon dioxide, or its equivalent in other greenhouse gases, kept out of the atmosphere.
Carbon credits grew out of the Kyoto Protocol of 1997, which set emission limits for industrialised countries. Under its Clean Development Mechanism, a project in a developing country that cut emissions earned Certified Emission Reductions, each worth one tonne of CO2 equivalent, which could be sold to those who needed to meet their targets. Other gases are converted to CO2 equivalent by their global warming potential; methane, for example, counts many times more than CO2. Carbon markets now work under Article 6 of the Paris Agreement, and India has notified its own Carbon Credit Trading Scheme.
Option A is wrong because a credit is not measured as 100 kg, nor in carbon alone. Option B is wrong because 100 kg is only a tenth of the unit. Option C is wrong because the unit is measured in carbon dioxide, not in carbon.
Exam tip: 1 carbon credit = 1 tonne of CO2 equivalent; idea born under the Kyoto Protocol (1997).
