Previous year Prelims questions on overlapping themes and topics.
Which one of the following statements best describes the term ‘Social Cost of Carbon’?
The term 'Social Cost of Carbon' is a measure of the economic damages, in dollars, that would result from emitting one additional ton of carbon dioxide into the atmosphere. It is used to value the climate impacts of rulemakings and helps policymakers understand the economic impacts of decisions that would increase or decrease emissions. Therefore, it is best described as the long-term damage done by a tonne of carbon dioxide emissions in a given year.
Consider the following statements:
Statement I:
At the 28th United Nations Climate Change Conference (COP28), India refrained from signing the “Declaration on Climate and Health”.
Statement II:
The COP28 Declaration on Climate and Health is a binding declaration; and if signed, it becomes mandatory to decarbonize health sector.
Statement III:
If India’s health sector is decarbonized, the resilience of its health-care system may be compromised.
Which one of the following is correct in respect of the above statements?
At COP28, India chose not to sign the “Declaration on Climate and Health,” and this decision can be understood by analyzing the nature of the declaration and India’s concerns. ✅ Statement I: Correct. India did not sign the COP28 Declaration on Climate and Health, unlike over 120 other countries. ❌ Statement II: Incorrect. The declaration is not legally binding; it is a voluntary political commitment. Signing it does not legally mandate countries to decarbonize their health sectors immediately. ✅Statement III: Correct. India’s concern is that rapid decarbonization of its health sector could compromise the resilience and accessibility of healthcare services, given current developmental challenges and resource constraints. Therefore, only Statement III correctly explains Statement I, while Statement II is factually wrong about the binding nature of the declaration.
Consider the following statements:
Statement-I: Carbon markets are likely to be one of the most widespread tools in the fight against climate change.
Statement-II: Carbon markets transfer resources from the private sector to the State.
Which one of the following is correct in respect of the above statements?
* Carbon markets, which include mechanisms like cap-and-trade systems and carbon offsets, are increasingly being used as a tool to incentivize emissions reductions and help in the fight against climate change. So, statement 1 is true. * Carbon markets typically work by transferring resources from emitters (usually in the private sector) to entities that can reduce or remove greenhouse gas emissions, which can be either private entities or the government. So, statement 2 can also be true.
“Climate Action Tracker" which emission reduction pledges of different countries is a:
The Climate Action Tracker (CAT) is an independent scientific analysis that tracks government climate action and measures it against the globally agreed Paris Agreement aim of holding warming well below 2C, and pursuing efforts to limit warming to 1.5C. A collaboration of two organisations, Climate Analytics and NewClimate Institute, the CAT has been providing this independent analysis to policymakers since 2009. CAT quantifies and evaluates climate change mitigation targets, policies, and actions. It also aggregates country action to the global level, determining likely temperature increases during the 21st century using the MAGICC climate model. CAT further develops sectoral analysis to illustrate the required pathways for meeting the global temperature goals.
Which organization has enacted the Nature Restoration Law (NRL) to tackle climate change and biodiversity loss?
✅ A. The European Union:
The Nature Restoration Law (NRL) is an EU legislative initiative adopted in 2024. It sets binding targets to restore ecosystems, fight climate change, and protect biodiversity across EU member states. ❌ B. The World Bank:
An international financial institution providing loans and grants; it does not enact laws like the NRL. ❌ C. OECD:
An organization promoting economic cooperation and policy coordination; it does not enact binding environmental laws such as the NRL. ❌ D. FAO:
A UN agency focused on hunger and agriculture; it does not enact regional laws like the NRL.
What is ‘Greenhouse Gas Protocol’?
The Greenhouse Gas (GHG) Protocol is a globally recognized framework for measuring, managing, and reporting greenhouse gas emissions. It was developed through a collaboration between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) to ensure a standardized and transparent approach to GHG accounting. The protocol helps businesses, governments, and organizations track their emissions consistently, facilitating accurate comparisons across sectors and regions. By providing clear guidelines for carbon accounting, it plays a crucial role in climate action strategies, regulatory compliance, and corporate sustainability efforts worldwide.
Consider the following pairs
| International Agreement | Set-up Subject |
|--------------------------|----------------------------|
| 1. Alma-Ata Declaration | Healthcare of the people |
| 2. Hague Convention | Biological and chemical weapons |
| 3. Talanoa Dialogue | Global climate change |
| 4. Under2 Coalition | Child rights |
Which of the pairs given above is/are correctly matched?
Pair 1 is correctly matched. Alma Ata Declaration: The Declaration of Alma-Ata was adopted at the International Conference on Primary Health Care, Almaty, Kazakhstan, 612 September 1978. It expressed the need for urgent action by all governments, all health and development workers, and the world community to protect and promote the health of all people. Pair 2 is not correctly matched. Hague Convention: The Hague Convention on the Civil Aspects of International Child Abduction or Hague Abduction Convention is a multilateral treaty developed by the Hague Conference on Private International Law that provides an expeditious method to return a child internationally abducted by a parent from one member country to another. Pair 3 is correctly matched. The Talanoa Dialogue is a process designed to help countries implement and enhance their Nationally Determined Contributions by 2020. The Dialogue was mandated by the Parties to the United Nations Framework Convention for Climate Change to take stock of the collective global efforts to reduce the emissions of greenhouse gases, in line with the goals of the Paris Agreement. Pair 4 is not correctly matched. The Under2 Coalition is a global community of state and regional governments committed to ambitious climate action in line with the Paris Agreement. The coalition brings together more than 220 governments that represent over 1.3 billion people and 43% of the global economy. Signatories commit to keeping global temperature rises to well below 2C with efforts to reach 1.5C.
Consider the following statements:
Statement I:
Article 6 of the Paris Agreement on climate change is frequently discussed in global discussions on sustainable development and climate change.
Statement II:
Article 6 of the Paris Agreement on climate change sets out the principles of carbon markets.
Statement III:
Article 6 of the Paris Agreement on climate change intends to promote inter-country non-market strategies to reach their climate targets.
Which one of the following is correct in respect of the above statements?
Article 6 of the Paris Agreement is crucial as it outlines international cooperation through both carbon markets and non-market approaches to help countries meet climate goals. ✅ Statement I is correct:
* Article 6 is widely discussed because it enables cooperation through market and non-market means to fight climate change. ✅ Statement II is correct:
* It defines rules for carbon markets, including carbon trading and credit mechanisms. ✅ Statement III is correct:
* It also promotes non-market tools like technology transfer and capacity building to reach climate targets. So, the correct answer is: A
With reference to ‘Global Climate Change Alliance’, which of the following statements is/are correct?
1. It is an initiative of the European Union.
2. It provides technical and financial support to targeted developing countries to integrate climate change into their development policies and budgets.
3. It is coordinated by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD).
Select the correct answer using the code given below:
Statement 1 is correct: The GCCA was established by the European Union to enhance climate cooperation with developing nations, particularly Least Developed Countries (LDCs) and Small Island Developing States (SIDS). Statement 2 is correct: A core objective of the GCCA is to provide technical and financial assistance to developing countries, helping them integrate climate change adaptation and mitigation into their national policies, development strategies, and budgets. Statement 3 is incorrect: The GCCA is coordinated by the European Commission through its established political dialogue and cooperation mechanisms. It is not managed by the World Resources Institute (WRI) or the World Business Council for Sustainable Development (WBCSD).
The term ‘Intended Nationally Determined Contribution’ is sometimes seen in the news in the context of:
The Intended Nationally Determined Contributions (INDCs) were submitted by countries before the Paris Agreement (2015) as their initial climate action plans to combat climate change. These documents outlined how each country intended to contribute to global efforts in reducing greenhouse gas (GHG) emissions and adapting to climate impacts. These were preliminary pledges, meaning they were not legally binding commitments but rather expressions of intent. Each country independently decided its contribution based on its capabilities, national circumstances, and priorities. Unlike top-down approaches in past climate treaties, INDCs followed a bottom-up approach. The plans outlined specific measures countries intended to take to reduce greenhouse gas emissions, increase renewable energy use, improve energy efficiency, and adapt to climate change impacts.
