Why: This is highly relevant for UPSC GS-III (Science & Technology and Environment) covering clean energy transition, climate change mitigation, and transport sector decarbonization. Questions test knowledge of National Green Hydrogen Mission components, India’s Net Zero 2070 commitment announced at COP26, hydrogen production methods (grey, blue, green hydrogen differences), fuel cell technology applications, and comparison with electric vehicle adoption under FAME scheme. The heavy transport sector contributes significantly to India’s transport emissions (contributing 13% of total GHG emissions), making hydrogen adoption crucial for meeting NDC targets and improving air quality in logistics corridors.

What: India launched the Cities Coalition for Circularity (C-3), a multi-national coalition promoting circular economy practices in urban areas. The circular economy model emphasizes resource efficiency, waste reduction, material reuse, and regenerative design principles, moving away from the traditional linear “take-make-dispose” economic model. C-3 brings together cities globally to share best practices, develop circular infrastructure, and implement sustainable urban management strategies.

How: The coalition facilitates knowledge exchange on circular economy interventions including zero-waste management systems, construction and demolition waste recycling, industrial symbiosis where one industry’s waste becomes another’s input, repair and refurbishment ecosystems, sharing economy platforms, and extended producer responsibility implementation. Member cities commit to circular procurement policies, establishing material recovery facilities, promoting product-as-a-service business models, and measuring circularity metrics like material footprint reduction and waste diversion rates. The initiative aligns with Smart Cities Mission and Swachh Bharat Mission 2.0 objectives.

Why: This is crucial for UPSC GS-III (Environment & Economy) covering sustainable development, waste management, and urban governance. Questions test understanding of circular economy principles versus linear economy, Extended Producer Responsibility (EPR) under Plastic Waste Management Rules 2016, Solid Waste Management Rules 2016 mandating waste segregation at source, and India’s resource consumption patterns (India uses 1.17 billion tonnes of raw materials annually). The coalition connects to international frameworks like the Ellen MacArthur Foundation’s circular economy model, SDG 11 (Sustainable Cities) and SDG 12 (Responsible Consumption), and India’s commitments under Basel Convention on hazardous waste management.

What: India’s first comprehensive river dolphin survey (2021-23) recorded 6,327 dolphins across the Ganga, Brahmaputra, Barak, and associated river systems. The Gangetic dolphin (Platanista gangetica), India’s national aquatic animal declared in 2009, serves as an indicator species for river ecosystem health. This baseline data is crucial for monitoring population trends, identifying critical habitats, and evaluating conservation interventions under Project Dolphin launched in 2020.

How: The survey employed standardized direct sighting methods using trained observers in boats covering approximately 6,000 km of river stretches across Uttar Pradesh (3,000+ dolphins), Bihar (1,500+ dolphins), Assam, West Bengal, Madhya Pradesh, Jharkhand, and Rajasthan. Wildlife Institute of India coordinated the multi-state effort using GPS-enabled data collection, photographic documentation, and habitat quality assessment including water depth, flow velocity, and prey fish abundance. The survey methodology followed international cetacean monitoring protocols, enabling future trend analysis through comparable periodic assessments.

Why: This is highly relevant for UPSC GS-III (Environment & Biodiversity) covering wildlife conservation, river ecology, and flagship species protection. Questions test knowledge of Project Dolphin objectives including Vikramshila Gangetic Dolphin Sanctuary (Bihar’s first dolphin sanctuary covering 60 km Ganga stretch), threats including illegal fishing, habitat fragmentation from dams and barrages, pollution reducing prey availability, and conservation measures under Wildlife Protection Act 1972 Schedule I. The dolphin population assessment connects to Namami Gange programme’s ecosystem restoration goals, aquatic biodiversity under National Biodiversity Action Plan, and India’s commitments under Convention on Migratory Species where Gangetic dolphins are listed in Appendix I requiring strict protection.

What: Jio Financial Services Limited (JFSL) acquired State Bank of India’s complete stake in Jio Payments Bank for ₹104 crore, converting it into a wholly-owned subsidiary. Jio Payments Bank, licensed by the Reserve Bank of India in 2015 and operational since 2018, was initially a joint venture between Reliance Industries (70%) and SBI (30%). This consolidation provides JFSL complete operational control as it expands its financial services portfolio.

How: Payments banks operate under a differentiated banking license model introduced by RBI in 2014 to promote financial inclusion and digital payments. They can accept deposits up to ₹2 lakh per customer, offer savings and current accounts, issue debit cards and enable digital payments, but cannot lend money or issue credit cards. Jio Payments Bank leverages Reliance Jio’s massive telecom customer base (450+ million subscribers) and retail touchpoints for distribution. The acquisition enables JFSL, which was demerged from Reliance Industries in 2023, to integrate payments infrastructure with planned offerings in lending, insurance distribution, wealth management, and stockbroking services.

Why: This is relevant for UPSC GS-III (Economy) and Banking exams covering differentiated banking models, fintech ecosystem, and financial inclusion. Questions test knowledge of payments banks versus small finance banks versus universal banks, RBI’s differentiated licensing framework, Jan Dhan-Aadhaar-Mobile (JAM) trinity for digital financial inclusion, and UPI ecosystem development (processing 16+ billion monthly transactions). Understanding JFSL’s vertical integration strategy is crucial for questions on fintech consolidation, corporate restructuring, and competition in India’s digital banking landscape including players like Paytm Payments Bank, Airtel Payments Bank, and India Post Payments Bank.

What: The Defence Research and Development Organisation’s (DRDO) Defence Bioengineering and Electromedical Laboratory (DEBEL) successfully tested the Integrated Life Support System (ILSS) equipped with On-Board Oxygen Generation System (OBOGS) for the Light Combat Aircraft (LCA) Tejas at altitudes up to 50,000 feet. This indigenous system provides breathable air to pilots during high-altitude combat operations, reducing dependence on liquid oxygen cylinders and enhancing operational flexibility.
