Q1. The concept of carbon credit originated from which one of the following?
Explanation
A carbon credit represents the reduction or removal of 1 metric ton of CO₂ or its equivalent from the atmosphere. It allows for compensating carbon emissions by funding projects that either reduce emissions, like renewable energy or energy efficiency, or remove CO₂ through methods like reforestation or carbon capture. The concept of carbon credits was formalized under the Kyoto Protocol (1997), introducing mechanisms like Emission Trading, where countries could sell excess credits, and the Clean Development Mechanism (CDM), allowing investments in emission-reduction projects in developing countries for credits.

Q2. In the context of CO₂ emission and Global Warming, what is the name of a market driven device under the UNFCCC that allows developing countries to get funds/ incentives from the developed countries to adopt better technologies that reduce greenhouse gas emissions?
Explanation
The Clean Development Mechanism (CDM) under the UNFCCC allows developing countries to receive funds from developed countries for adopting technologies that reduce green-house gas emissions, promoting sustainable development. The Clean Development Mechanism (CDM) allows developed countries to invest in emission-reduction projects in developing countries and earn carbon credits in return. Options (a), (b) and (d) are incorrect:
Carbon footprint refers to the total carbon dioxide (CO₂) emissions linked to the activities of an individual or entity (e.g., building, company, country). Emission Reduction Norms refer to regulations or standards set to limit the amount of greenhouse gases that can be emitted by industries, sectors, or countries. Carbon Credit Rating is a measure of how reliable and effective a carbon credit is in reducing emissions and helping the environment.
