Climate Change & Conventions

Statement 1 is Incorrect: Hydrogen obtained from fossil fuels (primarily natural gas) through steam methane reforming, where the resulting carbon emissions are captured and stored using Carbon Capture and Storage (CCS) technologies, is known as Blue Hydrogen, not Green Hydrogen. Statement 2 is Correct: Green Hydrogen is produced by splitting water into hydrogen and oxygen via electrolysis, using electricity generated entirely from renewable energy sources (such as solar or wind). It is a completely zero-emission process. Statement 3 is Correct: The National Green Hydrogen Mission launched by the Government of India has set quantified targets for 2030. It aims to develop a green hydrogen production capacity of at least 5 MMT (Million Metric Tonnes) per annum. This will lead to the abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030, alongside reducing fossil fuel imports and creating over 6 lakh jobs. Therefore, the correct option is B.

Statement I is Correct: India's Long-Term Low Emission Development Strategy (LT-LEDS) is indeed a crucial tool for achieving net-zero emissions by 2070. It outlines the strategic framework necessary for sectoral transitions in energy, transport, industry, and forestry to meet this long-term goal. Statement II is Incorrect: While India's 4th Biennial Update Report (BUR-4) does record an approximately 8% decrease in greenhouse gas emissions in 2020 compared to 2019, this decrease is attributed to the economic slowdown and lockdowns during the COVID-19 pandemic, not to structural or strategic efforts towards long-term emission reductions. Therefore, it does not empirically support the strategic framework of LT-LEDS. Statement III is Correct: The IPCC emphasizes that climate-resilient development depends on rapid, deep, and immediate emission reductions in the short term. This approach can be seen as contradicting the long-term focus of strategies like LT-LEDS if they do not also incorporate aggressive short-term actions. Therefore, the correct relationship is that Statement III contradicts the approach implicit in Statement I, making option B correct.

Statement 1 is Incorrect: Mangroves do not store freshwater, nor are they naturally suited for paddy cultivation. In fact, the clearing of mangrove forests to create agricultural land (like paddy fields) has historically been a primary driver of their destruction, rather than a reason for their protection. Statement 2 is Incorrect: Mangroves are halophytes, meaning they are highly salt-tolerant, not salt-sensitive. While their specialized root systems have ultrafiltration mechanisms to exclude salt, they do not convert coastal lands into freshwater zones. Furthermore, clearing mangroves for shrimp and aquaculture farms is a major threat to these ecosystems, not a conservation rationale. Statement 3 is Correct: In the context of climate resilience, mangroves act as natural bio-shields. Their dense root networks (such as stilt roots and pneumatophores) stabilize coastal soils and dissipate tidal energy, protecting coasts from storm surges and cyclones. Additionally, they are highly productive ecosystems that provide sustainable biomass resources (like timber, honey, and fish breeding grounds), forming a crucial livelihood base for rural coastal communities. Therefore, option D is the correct answer.

The Khasi Hills Community REDD+ Project holds the distinction of being India’s very first REDD+ (Reducing Emissions from Deforestation and Forest Degradation) project. It is certified under the Plan Vivo Standard, a globally recognized, fair-trade-styled framework specifically designed for community-based forest carbon projects. The project is located in the East Khasi Hills District of Meghalaya, situated along the Umiam River watershed. It is managed by a federation of 10 indigenous Khasi tribal kingdoms (comprising over 60 local communities), locally known as a Synjuk. The project utilizes REDD+ to protect existing dense forests and ancient indigenous sacred groves, and Assisted Natural Regeneration (ANR) to restore degraded open forests. Uttarakhand REDD+ project is incorrect as, while Uttarakhand has engaged in REDD+ readiness and pilot initiatives, it does not hold the title of the first Plan Vivo certified project in India. ICFRE-ICIMOD Transboundary REDD+ project in North-Eastern Himalayas is incorrect. This is a broader transboundary initiative focused on capacity building and REDD+ readiness across Himalayan countries, rather than a specific, first-of-its-kind Plan Vivo certified community project in India. Sikkim Mamley Kamrang Community REDD+ project is incorrect. Although Sikkim has undertaken significant forest conservation and climate mitigation efforts, the Khasi Hills project is officially recognized as India's first Plan Vivo certified REDD+ project. Therefore, the correct option is C.

Statement 1 is Incorrect: The Rainfed Area Development (RAD) scheme explicitly promotes Integrated Farming Systems (IFS) rather than monoculture. It integrates multi-cropping and rotational cropping with allied activities like horticulture, livestock, fishery, and agro-forestry to diversify income and build resilience. Official guidelines actively discourage single-cropping (monoculture) systems. Statement 2 is Incorrect: As the name implies, RAD targets rainfed areas (regions lacking assured irrigation) to build resilience against climate variability. It does not focus on expanding water-intensive crops like rice in already irrigated regions. Statement 3 is Correct: The core objective of RAD is to make rainfed agriculture more productive, sustainable, remunerative, and climate-resilient. By diversifying income sources through Integrated Farming Systems (IFS), RAD aims to minimize the risks associated with climatic variability (such as droughts, heat stress, or floods) and crop failure, ensuring stable livelihoods for farmers. Therefore, option D is the correct answer.

Wet-bulb temperature combines heat and humidity. When it exceeds 35°C, the human body can no longer cool itself through sweating, posing a serious threat to survival. ❌ Statement I: Incorrect
* Though flooding, cyclones, and droughts are valid climate threats, they are not directly related to the World Bank's warning about wet-bulb temperatures. ✅ Statement II: Correct
* When wet-bulb temperatures cross 35°C, the body cannot release heat, making it fatal for humans and animals.

✅ 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.

India’s CO₂ emissions come mainly from fuel combustion, especially electricity generation, and per capita emissions are higher than 0.5 tonnes. ❌ Statement I is incorrect:
* India’s per capita CO₂ emissions are around 1.9-2.0 tonnes, higher than 0.5 t CO₂/capita. ✅ Statement II is correct:
* India ranks second in the Asia-Pacific for total CO₂ emissions from fuel combustion, after China. ✅ Statement III is correct:
* Electricity and heat production (mainly coal-based) is the largest source of India’s CO₂ emissions. So, the correct answer is: C

Nature-based solutions involve using natural processes to tackle climate change and biodiversity loss, often needing dedicated financial support. ADB launched the Nature Solutions Finance Hub for Asia and the Pacific to fund nature-based solutions for climate and environmental challenges in the region.

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.
