Climate Change and India: Impacts, Targets and the 2035 Plan — SSB GD and Interview Notes
How climate change hits India, India's fair-share argument, the 2070 net-zero goal, the updated 2035 targets, renewable progress, the security angle for the forces, and a balanced GD structure.
Why you should know this
Climate change is a top GD and lecturette topic. The IO may ask: "Is India doing enough on climate change?" or "How does climate change affect national security?" A strong answer mixes facts about India's targets with India's position on fairness.
How climate change hits India
- Heatwaves: longer, hotter summers; record temperatures in many states.
- Erratic monsoon: heavy rain in short bursts, longer dry spells — floods and droughts in the same year.
- Melting glaciers: Himalayan glaciers feed the Ganga, Indus and Brahmaputra. Faster melting means floods now and water shortages later.
- Rising sea level and stronger cyclones: India has a long coastline and many island territories.
- Farming and health: lower crop yields, more heat stress and disease.
India's position — fairness
- India is the third-largest emitter in total, but its emissions per person are far below the world average.
- India's share of historical emissions (what has built up since the industrial age) is small. Rich countries caused most of the problem.
- So India argues for "Common But Differentiated Responsibilities" (CBDR) — everyone must act, but rich countries must do more and help poorer ones with money and technology.
This is the heart of India's climate diplomacy: India will act, and is acting, but development and fairness matter. Learn to explain this calmly in two lines.
Carbon dioxide per person, per year
| United States | 14.3 |
| China | 8.9 |
| World average | 4.7 |
| India | 2.0 |
India's targets
| Target | Details |
|---|
| Net zero | By 2070 (announced at COP26, Glasgow, 2021) |
| 50% non-fossil power capacity | Target for 2030 — achieved in 2025, five years early |
| Updated NDC (2035) | Cut emissions intensity of GDP by 47% from 2005 levels |
| Non-fossil power by 2035 | 60% of installed power capacity (partly conditional on finance) |
| Carbon sink | Extra 3.5–4 billion tonnes CO2 through forests and trees |
NDC means Nationally Determined Contribution — each country's own climate plan under the Paris Agreement (2015). India's updated plan for 2035 was approved in 2026.
India's climate milestones
| 2015 | Paris Agreement; International Solar Alliance founded |
| 2021 | Net zero by 2070 announced at COP26 |
| 2025 | 50% non-fossil power capacity reached | Five years early |
| 2026 | Updated plan (NDC) for 2035 | 47% intensity cut, 60% non-fossil capacity |
| 2070 | Net zero |
What India is doing
- Renewable energy: among the world's top countries for solar and wind capacity; target of 500 GW of non-fossil capacity by 2030.
- International Solar Alliance (founded by India and France in 2015).
- National Green Hydrogen Mission (2023).
- Mission LiFE — "Lifestyle for Environment", encouraging simple sustainable habits.
- CDRI — Coalition for Disaster Resilient Infrastructure, started by India in 2019.
- Electric mobility, energy efficiency, and the Green Credit Programme.
The challenges
- Coal still produces most of India's electricity.
- Climate finance: rich countries' promises of money have often fallen short. India called the 2024 global finance goal inadequate.
- Storage and grid: solar and wind need batteries and a strong grid.
- Jobs in coal regions need a fair transition.
The security angle
- Climate change is called a "threat multiplier" — it makes existing problems worse.
- Melting glaciers and extreme weather affect troops in places like Siachen and Ladakh.
- More floods, cyclones and landslides mean more disaster relief work for the forces.
- Water stress can increase tension between countries sharing rivers.
- Rising seas threaten coastal bases and island territories.
Why soldiers care about climate
| Mountain | Glaciers | Siachen and Ladakh get harder and riskier |
| CloudRain | More disasters | More rescue and relief work |
| Droplets | Water stress | Tension over shared rivers |
| Waves | Rising seas | Coastal bases and islands at risk |
Questions the IO may ask you
"Is India doing enough on climate change?"
What they check: Balance and knowledge.
Cover these points:
- India's progress: 50% non-fossil capacity reached early; 2035 targets; net zero by 2070.
- India's fairness argument: low per-person and historical emissions.
- Challenges: coal dependence, finance — and what more can be done.
"What can you personally do?"
What they check: Whether you practise what you say.
Cover these points:
- Two or three real habits — public transport or cycling, saving electricity, avoiding plastic, planting and caring for trees.
- Keep it honest and small.
Mistakes to avoid
- Don't say "India is the biggest polluter". In total it is third; per person it is low.
- Don't say "climate change is only the West's fault, so India need not act". India's own position is that it does act.
- Don't mix up weather and climate. Weather is day to day; climate is the long-term pattern.
- Don't quote targets loosely. "Net zero by 2070" — not 2050.
Useful GD topics: "Climate change: who should pay?", "Development vs environment", "Is net zero by 2070 enough?"
Point you can make: "India reached 50% non-fossil power capacity five years early, while its emissions per person are far below the world average. It is acting while it develops."
Balance it: "But coal still dominates our electricity, and heatwaves are already costing lives. We need faster storage, cleaner industry and real climate finance from rich countries."
