Introduction
CBDR-RC is a fundamental principle of international environmental law that recognises the shared responsibility of all countries to address climate change while acknowledging their different historical contributions and economic capabilities.
Key Features of CBDR-RC
1. Common Responsibility: All countries have a shared responsibility to protect the global environment and address climate change, irrespective of their level of economic development.
2. Differentiated Responsibility: Developed countries must undertake greater climate action because of their disproportionately higher historical contribution to greenhouse gas emissions.
3. Respective Capabilities: Climate obligations should reflect the financial, technological and institutional capacities of individual countries, allowing developing countries greater flexibility.
4. Historical Accountability: The principle recognises that developed countries have benefited from industrialisation based on fossil fuels and therefore bear greater responsibility for addressing accumulated emissions.
5. Financial and Technological Support: Developed countries are expected to provide financial assistance and facilitate technology transfer to developing countries to support their climate mitigation and adaptation efforts.
Constitutional and International Basis
- Rio Declaration, 1992 (Principle 7): Formally recognised CBDR by acknowledging the different contributions of countries to global environmental degradation.
- UNFCCC, 1992 (Article 3.1): Requires countries to protect the climate system on the basis of equity and CBDR-RC, with developed countries taking the lead.
- Paris Agreement, 2015: Reaffirms CBDR-RC in the light of different national circumstances, particularly under Article 2.2.
Conclusion
CBDR-RC remains essential for achieving climate justice by balancing environmental responsibility with developmental equity. Its effective implementation requires greater financial commitment, technology transfer and collective climate action.
