What: Chhattisgarh became India’s first state to implement the Green Gross Domestic Product (Green GDP) model, a revolutionary accounting framework that integrates ecological contributions and environmental costs into traditional economic measurements. Unlike conventional GDP that measures only monetary transactions, Green GDP accounts for natural resource depletion, environmental degradation, pollution costs, and ecosystem services like forest carbon sequestration, water purification, and biodiversity conservation. This model provides a more accurate picture of sustainable development by showing the true cost of economic growth on environmental capital.

How: Implementation involves comprehensive environmental accounting systems measuring forest cover changes, air and water quality indices, soil health parameters, wildlife population trends, and carbon footprint of economic activities. The state government collaborates with environmental research institutions, uses satellite imagery for monitoring land use changes, conducts regular biodiversity surveys, and integrates data from pollution control boards. Economic activities are assessed not just by revenue generated but also by environmental impact, allowing policy-makers to make informed decisions balancing growth with sustainability. Industries may face higher costs if environmental damage exceeds acceptable thresholds.

Why: Extremely relevant for UPSC GS Paper III (Environment & Sustainable Development) and Mains Essay on development models. Green GDP, alternative development indicators beyond conventional GDP, and sustainable development pathways are recurring exam topics. Questions frequently appear on: limitations of GDP as development indicator, environmental accounting methods, Natural Capital Accounting, comparison with Genuine Progress Indicator (GPI) and Human Development Index (HDI), and India’s environmental governance innovations. Connects to broader themes including climate action, ecological economics, compensatory afforestation, payments for ecosystem services, and reconciling economic growth with environmental conservation. Also relevant for understanding state-level policy innovations and laboratory federalism in India.

What: The Employees’ Provident Fund Organisation (EPFO) launched the Centralized Pension Payment System (CPPS), a transformative digital platform benefiting over 68 lakh pensioners across India. This unified system replaces the earlier decentralized model where pensioners received payments from different regional offices, often causing delays, tracking difficulties, and grievance resolution challenges. CPPS ensures seamless, timely pension disbursement directly to bank accounts through a single centralized portal, improving transparency and accountability in social security administration.

How: The system operates on a centralized digital architecture integrating all regional EPFO offices into one unified database. Pensioners’ data including bank details, identification documents (Aadhaar), and pension entitlements are digitized and verified. Monthly pension calculations are automated based on service records and contribution history. Direct Benefit Transfer (DBT) mechanism ensures payment reaches beneficiaries’ bank accounts on scheduled dates without manual intervention. The system includes features for online life certificate submission (Jeevan Pramaan), grievance redressal portal, SMS alerts for transaction confirmation, and mobile app for pension tracking. This eliminates geographical constraints allowing pensioners to access services from anywhere.

Why: Important for UPSC GS Paper II (Governance & Social Security) and questions on welfare administration in Mains. Social security reforms, digital governance in welfare delivery, and EPFO’s role in organized sector workers’ protection are frequent exam topics. Questions emerge on: challenges in pension system management, Digital India applications in social security, Direct Benefit Transfer efficiency, financial inclusion for senior citizens, and comparison with other pension schemes like National Pension System (NPS), Atal Pension Yojana (APY), and government employee pension under National Pension Scheme. Understanding CPPS helps in questions about administrative reforms, leveraging technology for citizen services, reducing leakages in benefit delivery, and ensuring dignity for elderly workers in formal sector.

What: The Government of India initiated the process to revise base years for two critical economic indicators: Gross Domestic Product (GDP) and Wholesale Price Index (WPI), updating them from 2011-12 to 2022-23. An 18-member expert committee has been constituted for WPI revision. Base year revision is essential to reflect structural changes in the economy, capture new sectors, update consumption patterns, and ensure economic data accurately represents current economic composition. The last major base year revision occurred in 2015 when it was updated from 2004-05 to 2011-12, making current data over 13 years old.

How: Base year revision involves comprehensive surveys of household consumption, industrial production, service sector activities, and price movements. For GDP calculation, it requires updating weights assigned to different sectors (agriculture, industry, services) to reflect their current contribution to economy. New sectors like digital economy, e-commerce, gig economy, and renewable energy that emerged or expanded significantly after 2011-12 will receive appropriate representation. For WPI, the revision includes updating commodity baskets, changing weights based on current production and trade patterns, and incorporating new products while removing obsolete items. Field surveys, national accounts statistics, production data from ministries, and trade statistics inform the revision process.

Why: Critical for UPSC GS Paper III (Indian Economy – Economic Indicators) and statistical methods questions in Prelims. Understanding GDP calculation methods, base year significance, inflation measurement, and economic data collection are recurring exam topics. Questions frequently appear on: limitations of GDP as welfare measure, difference between nominal and real GDP, GDP deflator versus CPI/WPI, challenges in measuring informal economy, and impact of base year changes on growth rate comparisons. Connects to broader themes including structural transformation of Indian economy (manufacturing to services shift), emergence of new economy sectors, improving statistical systems, and data-driven policy making. Also relevant for understanding how economic reforms, technological changes, and consumption pattern shifts necessitate periodic base year updates for accurate economic assessment.

What: India’s first glass bridge was inaugurated at Kanniyakumari, Tamil Nadu, under a ₹37 crore infrastructure project connecting two iconic monuments: the Vivekananda Rock Memorial and the Thiruvalluvar Statue.
