Global Climate & Environmental Performance Indices
Climate Change Performance Index (CCPI)
To compare how countries are responding to climate change, an independent ranking system called the Climate Change Performance Index (CCPI) is used.
What is CCPI?
- Covers 63 countries + the EU
- Together account for 92% of global GHG emissions
- Published annually since 2005
- Objective: Track progress towards Paris Agreement goals (≤2°C, preferably 1.5°C).
Institutions Behind CCPI
- Germanwatch (Germany)
- New Climate Institute
- Climate Action Network
How Does CCPI Measure Performance?
CCPI evaluates countries using 14 indicators, grouped into 4 categories:
| Category | Weight |
|---|---|
| GHG emissions | 40% |
| Renewable energy | 20% |
| Energy use | 20% |
| Climate policy | 20% |
👉 This weighting shows that actual emissions matter more than promises alone.
India in CCPI 2025
- Rank: 10th (↓ 2 places from 2024, but still Top 10)
- Overall Insight: Strong relative performer among developing countries.
Category-wise Performance
- GHG Emissions: High (low per-capita emissions)
- Energy Use: High (efficiency improvements)
- Climate Policy: Medium (implementation gaps)
- Renewable Energy: Low (coal dependence despite solar push)
Drivers
- Solar expansion, EV push, leadership in International Solar Alliance.
Constraints
- Continued coal reliance
- Weak enforcement of climate policies
Global Rankings Snapshot
Top Performers (Ranks 4–10)
- 4 – Denmark (global leader: renewables, strong policy)
- 5 – Netherlands
- 6 – United Kingdom
- 7 – Philippines
- 8 – Morocco
- 9 – Norway
- 10 – India
Bottom Performers (Ranks 58–67)
- Japan, Argentina, Kazakhstan, Canada, South Korea, Russia, UAE, Saudi Arabia, Iran
- Common Issues: High fossil fuel dependence, weak climate laws, poor renewable uptake.
G20 Performance Highlights
- Better Performers: India (10), UK (6)
- Poor Performers: USA, China, Canada, Saudi Arabia
- Reason: High per-capita energy use, fossil fuel subsidies, weak policy enforcement.
Key Trends from CCPI 2025
- Vacant Top 3: No country climate-ready for 1.5°C pathway.
- Renewables = Bottleneck: Even leaders lag in renewable share.
- Policy–Practice Gap: Strong pledges, weak execution.
- Per Capita vs Total Emissions:
- India → low per capita, high absolute emissions
- Developed nations → high per capita energy use
Way Forward
For India
- Phase-out inefficient coal plants (target ~2030).
- Redirect subsidies to renewables, storage, smart grids.
- Strengthen enforcement + carbon pricing mechanisms.
- Scale rooftop solar, EV public transport.
- Leverage ISA for finance & tech transfer.
For the World
- Eliminate fossil fuel subsidies.
- Boost climate finance (e.g., Green Climate Fund).
- Integrate renewables with emission cuts.
- Invest in CCUS, grid-scale storage, smart grids.
Environmental Performance Index (EPI)
While CCPI focuses mainly on climate action, the Environmental Performance Index (EPI) looks at overall environmental performance.
What is EPI?
- A biennial index
- Started in 2002 as the Environmental Sustainability Index (ESI)
- Designed to support the UN Millennium Development Goals
Environmental Performance Index (EPI) 2026
The EPI is a biennial index developed by researchers associated with Yale University and Columbia University. The 2026 edition assesses 177 countries using 47 indicators across 12 issue categories, grouped under Environmental Health, Ecosystem Vitality and Climate Change Mitigation.
India in EPI 2026
- Rank: 176 / 177
- Score: 22.46
- 10-year change: +7.47
- Environmental Health: 174th
- Ecosystem Vitality: 171st
- Climate Change Mitigation: 130th
- Air Quality: 175th
India therefore remains among the lowest-ranked countries overall, although its positive 10-year change indicates improvement over time.
India’s methodological concerns regarding EPI
Issues Raised by India
- Projected GHG Methodology: Uses average emission trends → ignores development stage & future transitions.
- Carbon Sinks Ignored → Forests & wetlands not factored despite being major carbon absorbers.
- Biodiversity Measurement Gaps: Focus on extent of ecosystems, not condition or productivity.
- Missing Indicators → Agro-biodiversity, Soil health, Food loss & waste
- Data Constraints → Developing countries face monitoring and data-collection challenges.
Issues in General
- Development vs Environment Trade-off
- Fossil-fuel dependent economies face transition barriers.
- Funding Gap: Insufficient climate finance from developed to developing nations.
- Transboundary Challenges: Air pollution, water sharing, wildlife conservation require multilateral cooperation.
