Climate Change, UNFCCC and COP

By YESPYQ · Updated July 2026 · 6 min read
Quick answer

Climate change is the long-term warming of the planet caused mainly by human greenhouse-gas emissions. Global action is coordinated under the UNFCCC (1992), whose members meet annually at the COP. The Kyoto Protocol (1997) and the Paris Agreement (2015, aiming to limit warming to 1.5-2°C) are the key treaties. India has pledged net-zero emissions by 2070.

Climate change refers to long-term shifts in temperature and weather patterns, driven largely by human emissions of greenhouse gases (GHGs) such as carbon dioxide and methane from burning fossil fuels, deforestation and industry. It is one of the defining global challenges of our time, causing rising sea levels, extreme weather and threats to food and water security. Global cooperation to tackle it is coordinated under the UN Framework Convention on Climate Change (UNFCCC).

The science in brief

The greenhouse effect is natural and keeps Earth habitable, but human activities have sharply raised the concentration of greenhouse gases, trapping more heat and warming the planet — global average temperatures have already risen by over 1°C since pre-industrial times. The Intergovernmental Panel on Climate Change (IPCC), the UN's scientific body, assesses this evidence and warns that limiting warming to 1.5°C is critical to avoid the worst impacts, requiring deep and rapid emission cuts.

UNFCCC and the COP

The UNFCCC, adopted at the 1992 Rio Earth Summit and in force from 1994, is the parent treaty for global climate action, with near-universal membership. Its members meet every year at the Conference of the Parties (COP) — for example COP21 in Paris and COP28 in Dubai — to negotiate and review climate action. The Convention set the overall goal of stabilising greenhouse-gas concentrations at a safe level and enshrined key principles that guide negotiations.

Key principles — CBDR and equity

A cornerstone of the UNFCCC is the principle of 'Common But Differentiated Responsibilities and Respective Capabilities' (CBDR-RC). It recognises that while all countries must act, developed nations bear greater historical responsibility for emissions and have more resources, so they should take the lead and support developing countries with finance and technology. Equity and climate justice — the idea that those least responsible often suffer the most — are central to India's negotiating stance.

The Kyoto Protocol and Paris Agreement

The Kyoto Protocol (1997) was the first treaty to set legally binding emission-reduction targets, but only for developed countries, and had limited success. It was succeeded by the landmark Paris Agreement (2015), under which nearly all countries — developed and developing — pledge climate action through Nationally Determined Contributions (NDCs), which they update every few years. The Paris Agreement's goal is to hold global warming to well below 2°C above pre-industrial levels, while pursuing efforts to limit it to 1.5°C, and to reach net-zero in the second half of the century.

India's stand and actions

India champions CBDR and climate justice, stressing that developed nations must deliver on finance (the promised $100 billion a year) and technology transfer. It has pledged to reach net-zero emissions by 2070 and, at COP26, announced the 'Panchamrit' commitments, including large renewable-energy capacity and reducing the emissions intensity of its economy. India also leads global initiatives like the International Solar Alliance (ISA) and the Coalition for Disaster Resilient Infrastructure (CDRI), and promotes the 'LiFE' (Lifestyle for Environment) mission for sustainable living.

Challenges in global climate action

Despite decades of negotiation, emissions continue to rise and the world is not on track for the 1.5°C goal. Key sticking points include the gap between pledges and action, inadequate climate finance for developing countries, disputes over 'loss and damage' compensation, and the difficult balance between development needs and decarbonisation for countries like India. Bridging these divides fairly is the central challenge of climate diplomacy.

Why it matters for UPSC

The UNFCCC, COP, the Kyoto Protocol, the Paris Agreement's temperature goals, NDCs, the CBDR principle and India's net-zero year (2070) and initiatives (ISA, CDRI, LiFE) are high-frequency Environment and current-affairs topics in both Prelims and Mains.

Key takeaways

  • Climate change is driven mainly by human greenhouse-gas emissions; warming has crossed 1°C.
  • The UNFCCC (1992) is the parent treaty; members meet annually at the COP.
  • CBDR-RC means all must act but developed nations should lead and support developing ones.
  • The Kyoto Protocol (1997) bound only developed countries; the Paris Agreement (2015) covers nearly all via NDCs.
  • The Paris goal is to limit warming to well below 2°C, ideally 1.5°C.
  • India targets net-zero by 2070 and leads the ISA, CDRI and LiFE initiatives.

Frequently asked questions

What is the temperature goal of the Paris Agreement?

To limit global warming to well below 2°C above pre-industrial levels, while pursuing efforts to keep it to 1.5°C.

By when has India pledged to reach net-zero emissions?

India has pledged to achieve net-zero emissions by 2070.

What is the UNFCCC?

The UN Framework Convention on Climate Change, adopted at the 1992 Rio Earth Summit, is the parent treaty under which countries cooperate on climate action through annual COP meetings.

What does CBDR mean?

'Common But Differentiated Responsibilities' — the principle that all countries must address climate change, but developed nations bear greater responsibility and should lead and support developing countries.

What is the difference between the Kyoto Protocol and the Paris Agreement?

The Kyoto Protocol set binding targets only for developed countries, while the Paris Agreement involves nearly all countries acting through their own Nationally Determined Contributions.
