1. Introduction
Climate change, energy security and sustainable development are closely interconnected issues in contemporary international relations. The growing demand for energy, dependence on fossil fuels, environmental degradation and the increasing effects of climate change have encouraged states to cooperate at the global and regional levels.
Climate Summits provide platforms for international negotiations on climate change. Energy security concerns the availability, affordability, reliability and sustainability of energy supplies. The International Solar Alliance (ISA) represents an important initiative to promote solar energy and strengthen international cooperation in the transition towards cleaner energy.

2. Meaning of Climate Change
Climate change refers to long-term changes in temperature, rainfall patterns, weather conditions and other characteristics of the Earth’s climate system.
Although climate has changed naturally throughout Earth’s history, contemporary climate change is primarily associated with increasing concentrations of greenhouse gases resulting from human activities.
Major Greenhouse Gases
- Carbon dioxide (CO₂)
- Methane (CH₄)
- Nitrous oxide (N₂O)
- Certain industrial gases
Major Human Causes
- Burning coal, oil and natural gas
- Deforestation
- Industrial activities
- Transport
- Agriculture
- Land-use changes
3. Major Effects of Climate Change
Climate change can produce:
- Rising global temperatures
- Changing rainfall patterns
- More frequent or intense heatwaves
- Melting glaciers and ice sheets
- Sea-level rise
- Droughts
- Floods
- Threats to agriculture
- Water insecurity
- Biodiversity loss
- Health risks
- Climate-induced displacement
These impacts can affect both human security and national development.
4. What is a Climate Summit?
A Climate Summit is a high-level international meeting where governments negotiate and discuss collective responses to climate change.
The most important global climate negotiations take place under the framework of the United Nations Framework Convention on Climate Change (UNFCCC).
The annual Conference of the Parties is commonly known as the COP.

5. United Nations Framework Convention on Climate Change
The UNFCCC was adopted in 1992 at the Rio Earth Summit and entered into force in 1994.
Its central objective is to stabilise greenhouse-gas concentrations in the atmosphere at a level that would prevent dangerous human interference with the climate system.
The UNFCCC established the basic framework for subsequent international climate negotiations.
6. Kyoto Protocol
The Kyoto Protocol was adopted in 1997 under the UNFCCC and entered into force in 2005.
It established legally binding emission-reduction commitments for developed countries and economies listed under its framework.
Important Principle
The Kyoto framework reflected the principle of:
Common but Differentiated Responsibilities (CBDR)
The principle recognises that states share responsibility for addressing climate change but have different historical contributions, capabilities and circumstances.
7. Paris Agreement
The Paris Agreement was adopted at COP21 in Paris in 2015 and entered into force in 2016.
It represents one of the most significant developments in international climate diplomacy.
Major Objectives
The Paris Agreement seeks to:
- Hold the increase in global average temperature to well below 2°C above pre-industrial levels.
- Pursue efforts to limit warming to 1.5°C.
- Strengthen adaptation to climate impacts.
- Promote climate-resilient development.
- Mobilise climate finance.
- Encourage progressively stronger national climate action.
8. Nationally Determined Contributions
A major feature of the Paris Agreement is the system of Nationally Determined Contributions (NDCs).
Each country determines its own climate commitments according to its national circumstances.
