Sustainable Development and Environmental Issues for RBI Grade B ESI
Last updated: 2026-11-10 · MockMentor
"Sustainable Development and Environmental issues" completes the Growth and Development unit of the RBI Grade B Phase 2 Economic and Social Issues (ESI) syllabus. It has been one of the most consistent topics in the exam, in both objective and descriptive papers, because it connects growth, poverty, climate change, energy, finance and global negotiations. For RBI it is also a live policy issue: climate risk is now part of how banks and the central bank think about financial stability.
In one line: sustainable development means growing in a way that does not destroy the natural base that future generations will need, and for India it means lifting incomes while cutting the carbon intensity of growth.
Basic concepts
- Sustainable development: "development that meets the needs of the present without compromising the ability of future generations to meet their own needs", as defined by the Brundtland Commission in its 1987 report "Our Common Future".
- Three pillars: economic growth, social inclusion and environmental protection. Development is sustainable only when all three move together.
- Natural capital: forests, water, soil, minerals, clean air and biodiversity, treated as assets that yield services to the economy.
- Weak and strong sustainability: weak sustainability allows natural capital to be replaced by man-made capital as long as total wealth does not fall. Strong sustainability holds that some natural assets, such as a stable climate, cannot be replaced at all.
- Carbon intensity of GDP: greenhouse gas emissions per unit of GDP. A falling intensity means growth is becoming cleaner, even if total emissions still rise.
- Net zero: a state where the greenhouse gases a country emits are balanced by those removed from the atmosphere.
- Nationally Determined Contribution (NDC): each country's climate pledge under the Paris Agreement, updated every five years.
- Common But Differentiated Responsibilities (CBDR): the principle that all countries must act on climate change, but rich countries that caused most past emissions must do more and help developing countries.
Why in News?
- In March 2026, the Union Cabinet approved India's NDC for 2031 to 2035: cut the emissions intensity of GDP by 47% from 2005 levels by 2035, raise non-fossil sources to 60% of installed power capacity, and create an additional carbon sink of 3.5 to 4.0 billion tonnes of carbon dioxide equivalent.
- India's non-fossil power capacity crossed 300 gigawatts (GW) on 31 July 2026, more than 54% of total installed capacity of about 552 GW, and over 60% of the 500 GW target for 2030.
- India ranked 94th out of 167 countries in the UN Sustainable Development Solutions Network's Sustainable Development Report 2026, its best ever, with a score of 68.3.
- The 31st Conference of the Parties (COP31) to the United Nations Framework Convention on Climate Change (UNFCCC) opened in Antalya, Türkiye, on 9 November 2026 and runs till 20 November, with climate finance and the transition away from fossil fuels at the centre.
How the idea developed
| Year | Milestone | Why it matters |
|---|---|---|
| 1972 | UN Conference on the Human Environment, Stockholm | First global meeting on the environment; led to the UN Environment Programme (UNEP). Indira Gandhi spoke of poverty as the biggest polluter. |
| 1972 | "The Limits to Growth" report (Club of Rome) | Warned that unchecked growth would exhaust resources |
| 1987 | Brundtland Commission report | Defined sustainable development |
| 1992 | Earth Summit, Rio de Janeiro | Agenda 21; the UNFCCC, the Convention on Biological Diversity and the desertification convention were opened for signature |
| 1997 | Kyoto Protocol | Binding emission cuts for developed countries only |
| 2000 | Millennium Development Goals (MDGs) | Eight goals for 2015, mainly for developing countries |
| 2015 | 2030 Agenda and the Sustainable Development Goals (SDGs) | 17 goals and 169 targets, for all countries |
| 2015 | Paris Agreement | All countries set their own targets; goal to keep warming well below 2°C and try for 1.5°C |
The Sustainable Development Goals
The SDGs were adopted by the UN General Assembly in September 2015 and run until 2030. Unlike the MDGs, they apply to all countries, cover the environment as fully as poverty and health, and use the principle of "leaving no one behind".
| Group | Goals |
|---|---|
| People | 1 No poverty, 2 Zero hunger, 3 Good health, 4 Quality education, 5 Gender equality, 6 Clean water and sanitation |
| Prosperity | 7 Clean energy, 8 Decent work and growth, 9 Industry and infrastructure, 10 Reduced inequality, 11 Sustainable cities |
| Planet | 12 Responsible consumption, 13 Climate action, 14 Life below water, 15 Life on land |
| Peace and partnership | 16 Peace, justice and strong institutions, 17 Partnerships for the goals |
Where India stands
NITI Aayog tracks state performance through the SDG India Index. In its fourth edition, for 2023-24, India's composite score rose to 71 out of 100, from 66 in 2020-21, and every state improved. Kerala and Uttarakhand were at the top.
Globally, the 2026 Sustainable Development Report placed India at 94, up from 112 in 2015. It flagged major challenges in zero hunger, health, gender equality, sustainable cities, oceans, life on land and strong institutions, and said that progress on responsible consumption and climate action was slipping. Worldwide, only a small share of SDG targets are on track for 2030, with conflict, debt and weak finance holding poorer countries back.
Principles of sustainable development
International law and Indian courts have built a set of principles that turn the idea of sustainable development into rules for decisions.
| Principle | What it means | Where it comes from |
|---|---|---|
| Inter-generational equity | The present generation holds the earth in trust for future generations and must not leave them a degraded environment | Stockholm Declaration (1972); Brundtland report |
| Precautionary principle | Where there is a threat of serious or irreversible damage, lack of full scientific certainty is no reason to delay preventive action | Rio Declaration (1992), Principle 15 |
| Polluter pays principle | Whoever causes pollution must bear the cost of cleaning it up and compensating victims | Rio Declaration, Principle 16 |
| Public trust doctrine | Natural resources such as rivers, forests and seashores are held by the state in trust for the public and cannot be handed over for private use | Recognised by India's Supreme Court in M.C. Mehta v. Kamal Nath (1996) |
| Common But Differentiated Responsibilities | All countries share the duty to protect the environment, but developed countries bear a greater share | UNFCCC (1992) |
| Duty to cooperate | States must cooperate and share information to prevent cross-border environmental harm | Rio Declaration |
| Poverty eradication | Eradicating poverty is a requirement for sustainable development, because the poor depend most directly on natural resources | Rio Declaration, Principle 5 |
In Vellore Citizens' Welfare Forum v. Union of India (1996), the Supreme Court held that the precautionary principle and the polluter pays principle are part of Indian environmental law. The Court has also read the right to a clean environment into the right to life under Article 21 of the Constitution.
The economics of the environment
Why markets fail the environment
Pollution is a negative externality: a factory that pollutes a river does not pay the cost borne by people downstream, so it produces more than is socially best. Clean air and a stable climate are public goods: no one can be excluded from them, so no one has a reason to pay for them. Common resources such as fisheries, groundwater and forests face the "tragedy of the commons", where each user takes as much as possible and the resource collapses.
Tools to correct it
| Tool | How it works | Example |
|---|---|---|
| Regulation (command and control) | Limits or standards set by law | Vehicle emission norms (Bharat Stage VI), effluent standards |
| Pigouvian tax | Tax equal to the damage caused, so the polluter pays | Carbon taxes in Europe; India's former coal cess |
| Cap and trade | A cap on total emissions, with permits that firms can trade | Carbon Credit Trading Scheme (CCTS), Perform Achieve and Trade (PAT) scheme |
| Subsidies for clean options | Lower the cost of green technology | Solar and electric vehicle incentives |
| Property rights (Coase theorem) | Clear rights allow affected parties to bargain | Community forest rights |
The environmental Kuznets curve
This idea holds that pollution rises in the early stages of growth and falls once incomes reach a certain level, as people demand cleaner air and can afford cleaner technology. It fits some local pollutants, such as sulphur dioxide, but not carbon emissions, which have kept rising with income in most countries. The policy lesson is that countries cannot simply wait to grow out of pollution.
Climate change: the science
The greenhouse effect is natural: gases in the atmosphere trap part of the heat the earth radiates, keeping the planet about 33°C warmer than it would otherwise be. Since the Industrial Revolution, burning coal, oil and gas, clearing forests and intensive farming have raised the concentration of these gases, so more heat is trapped and the planet warms.
| Greenhouse gas | Main sources | Note |
|---|---|---|
| Carbon dioxide (CO2) | Burning fossil fuels, cement, deforestation | The largest contributor; stays in the atmosphere for centuries |
| Methane (CH4) | Rice paddies, livestock, landfills, gas leaks | Far stronger than CO2 per tonne over 20 years, but shorter-lived |
| Nitrous oxide (N2O) | Fertilisers, industrial processes | Long-lived and potent |
| Fluorinated gases (HFCs, PFCs, SF6) | Refrigerants, air conditioners, industry | Very potent; HFCs are being phased down under the Kigali Amendment |
The Intergovernmental Panel on Climate Change (IPCC), in its Sixth Assessment Report (2021 to 2023), concluded that human influence has unequivocally warmed the climate, and that global temperature had risen by about 1.1°C over pre-industrial levels by 2011-2020. The World Meteorological Organization reported that 2024 was the first calendar year in which the global average temperature was more than 1.5°C above pre-industrial levels.
The evidence is visible across the world: rising sea levels, shrinking glaciers and Arctic sea ice, more frequent and intense heatwaves, heavier rainfall events, longer droughts and warming, more acidic oceans. For India, the main risks are extreme heat, erratic monsoon rainfall, floods in the Himalayas and the north-east, stronger cyclones along the coasts, and the retreat of Himalayan glaciers that feed the Ganga, Indus and Brahmaputra.
Global conventions and protocols
| Agreement | Year (in force) | What it does |
|---|---|---|
| Ramsar Convention | 1971 (1975) | Conservation of wetlands of international importance. India has the largest network of Ramsar sites in Asia. |

| Agreement on Biodiversity Beyond National Jurisdiction (High Seas Treaty) | 2023 (2026) | Protects marine life in the high seas, outside any country's waters |
Kyoto's market mechanisms
- Clean Development Mechanism (CDM): a developed country could fund an emission-reducing project in a developing country and count the reduction towards its own target. India was one of the largest hosts of CDM projects.
- Joint Implementation: the same idea, between two developed countries.
- International Emissions Trading: developed countries with spare emission allowances could sell them to others.
The Paris Agreement's Article 6 has replaced these with new rules for trading carbon credits between countries and through a UN-supervised market.

Climate change and India
India's position
India is the third-largest emitter of greenhouse gases in total, but its emissions per person are well below the world average and a fraction of those of the United States or the European Union. Its historical share of the carbon already in the atmosphere is small. At the same time, India is among the countries most exposed to climate risk: heatwaves, erratic monsoons, floods, cyclones, glacier melt and sea-level rise threaten farms, cities and coasts. India's stand in talks has been to accept action while insisting on equity, CBDR and finance and technology from rich countries.
India's commitments
| Pledge | Target | Status |
|---|---|---|
| First NDC (2015) | Cut emissions intensity by 33% to 35% from 2005 by 2030; 40% non-fossil power capacity by 2030 | Non-fossil target met in 2021, nine years early |
| Panchamrit at COP26, Glasgow (2021) | Net zero by 2070; 500 GW non-fossil capacity and half of energy needs from renewables by 2030 | Net zero is the long-term goal |
| Updated NDC (2022) | Cut emissions intensity by 45% from 2005 by 2030; 50% non-fossil capacity by 2030 | Emissions intensity fell 36% between 2005 and 2020; non-fossil share crossed 50% in 2025 |
| NDC for 2031 to 2035 (2026) | Cut emissions intensity by 47% from 2005 by 2035; 60% non-fossil capacity; carbon sink of 3.5 to 4.0 billion tonnes | New pledge |
The National Action Plan on Climate Change
India's National Action Plan on Climate Change (NAPCC), released in 2008, set out eight national missions. All states and union territories have their own State Action Plans on Climate Change.
| Mission | Focus |
|---|---|
| National Solar Mission | Expand solar power; its target was raised to 100 GW by 2022 and now sits within the 500 GW non-fossil goal for 2030 |
| National Mission for Enhanced Energy Efficiency | Market tools for energy saving, including the Perform Achieve and Trade (PAT) scheme for heavy industry |
| National Mission on Sustainable Habitat | Energy-efficient buildings, urban planning, public transport and waste management |
| National Water Mission | Conserve water, cut waste and raise water-use efficiency by 20% |
| National Mission for Sustaining the Himalayan Ecosystem | Protect Himalayan glaciers and mountain ecosystems |
| National Mission for a Green India | Expand and improve forest and tree cover |
| National Mission for Sustainable Agriculture | Make farming more resilient to climate change through soil health, water use and dryland farming |
| National Mission on Strategic Knowledge for Climate Change | Build research and data on climate change |
The National Adaptation Fund on Climate Change (NAFCC), set up in 2015, funds adaptation projects in states that are especially vulnerable. The National Clean Air Programme (NCAP), launched in 2019, aims to cut particulate pollution (PM10) in about 130 cities by up to 40% by 2025-26 compared with 2017-18 levels.
Other key policies
- Mission LiFE (Lifestyle for Environment), 2022: promotes sustainable consumption by individuals and communities, an idea India has taken to global forums.
- Carbon Credit Trading Scheme, 2023: creates a domestic carbon market. Industries in energy-intensive sectors get emission-intensity targets, and those who beat them can sell credits.
- Green Credit Programme, 2023: rewards voluntary actions such as tree planting and water conservation with tradable credits.
- National Green Hydrogen Mission, 2023: aims for 5 million tonnes of green hydrogen production a year by 2030.
- Energy transition: large solar parks, rooftop solar under PM Surya Ghar, the PM-KUSUM scheme for solar pumps, ethanol blending (20% reached in 2025), and support for electric vehicles and battery storage.
- International initiatives led by India: the International Solar Alliance (with France, 2015), the Coalition for Disaster Resilient Infrastructure (2019) and the Global Biofuels Alliance (2023).
Global talks: COP30 and COP31
At COP30 in Belém, Brazil, in November 2025, countries agreed to aim to triple finance for adaptation by 2035, set up a mechanism to support workers and communities affected by the shift to clean energy, and launched steps to speed up the implementation of national climate plans. But the final deal had no roadmap for moving away from fossil fuels, despite calls from more than 80 countries. That gap, along with the shortfall in climate finance for developing countries, has been carried into COP31 at Antalya, which began on 9 November 2026.
Climate finance is the hardest issue. At COP29 in Baku in 2024, developed countries agreed to a goal of mobilising at least US$300 billion a year for developing countries by 2035, far below the US$1.3 trillion that developing countries asked for. India called the figure inadequate.

Green finance and the role of RBI
The shift to clean energy needs very large investment, and the financial system has to fund it while managing the risks that climate change poses to banks' own balance sheets.
- Climate risk for banks: physical risks (floods damaging assets of borrowers, droughts hurting farm loans) and transition risks (loans to coal or high-emission firms losing value as policy changes). RBI has issued draft rules asking banks to disclose climate-related risks and has run climate scenario analysis.
- Sovereign green bonds: the Government of India has issued green bonds since January 2023, using the money only for green projects such as solar power and clean transport.
- Green deposits: RBI's framework lets banks raise deposits whose money must be lent to green activities.
- Priority sector lending: loans for renewable energy are part of priority sector targets.
- Network for Greening the Financial System (NGFS): RBI joined this group of central banks and supervisors in 2021.
- Climate finance taxonomy: the Union Budget 2024-25 announced a taxonomy to define what counts as green or transition finance, so that "greenwashing" can be checked.
Growth versus environment: the debate
One side argues that India cannot afford to slow growth for climate goals. Millions still need electricity, housing and jobs; coal remains the backbone of power supply; and rich countries grew without such limits. Forcing a fast transition could raise costs and hurt the poor.
The other side argues that the trade-off is overstated. Solar power is now among the cheapest sources of new electricity in India, clean industries create jobs, and pollution already costs India heavily in lost health and productivity. Climate damage, from heatwaves to failed monsoons, will itself slow growth if left unchecked.
A balanced view is that India's path is not to choose between growth and the environment, but to change the pattern of growth: faster renewable expansion, energy efficiency and cleaner industry, with coal phased down over time and the transition made fair for workers and coal-dependent states.
Challenges
- Coal still supplies most of India's electricity generation, and coal regions depend on it for jobs and revenue.
- Renewable power needs storage and grid upgrades to manage its variable supply.
- Climate finance from developed countries falls short, and private capital for green projects is costly.
- Air and water pollution remain severe, with weak enforcement at local levels.
- Green technologies depend on imported minerals and components, mainly from China.
- Adaptation needs (resilient farms, cities and coasts) are huge but receive less funding than mitigation.
Way forward
- Expand renewable energy with battery storage, pumped hydro and a stronger grid, and plan a just transition for coal-dependent regions.
- Make the domestic carbon market credible, with clear caps and wider coverage.
- Scale up green finance through a clear taxonomy, disclosure rules and blended finance that uses public money to draw in private investment.
- Build adaptation into every development plan: drought-proof agriculture, heat-ready cities and early warning systems.
- Push for climate finance and technology transfer in global talks, with CBDR as the basis.
- Promote sustainable consumption through Mission LiFE, circular economy rules and better waste management.
