How does the principle of 'Common but Differentiated Responsibilities' shape India's position in multilateral climate diplomacy?

Embedded in the UNFCCC (1992) and reaffirmed in the Paris Agreement, 'Common but Differentiated Responsibilities and Respective Capabilities' (CBDR-RC) holds that all states share the climate burden, but unequally, according to historical emissions and capacity. It is the organising principle of India's climate diplomacy.

Shapes the normative case for equity

• India frames responsibility by cumulative and per capita emissions, not current totals: the Prime Minister has noted India's per capita emissions are less than half the global average, while developed countries' are about six times India's [1].
• This converts climate action into a question of historical and moral responsibility, resisting a uniform standard for unequal economies.

Shapes the form of India's commitments

• India pledges growth-adjusted, not absolute, targets — a 45% cut in emissions intensity of GDP and 50% non-fossil installed capacity by 2030, with net-zero by 2070 [2].
• The third NDC (2031–35) continues this design: 47% intensity cut, 60% non-fossil capacity, a 3.5–4 billion tonne carbon sink [3].

Shapes demands on developed countries

• CBDR-RC underpins India's insistence on climate finance and technology transfer as obligations, not charity; India has criticised the COP29 goal of $300 billion a year by 2035 as inadequate and vaguely sourced [4].
• It also grounds India's objection to unilateral trade measures such as the EU's Carbon Border Adjustment Mechanism, in force from January 2026 on steel, aluminium and fertilisers [5], which applies one carbon standard irrespective of differentiated capability.

Shapes credibility and leadership

• Delivery strengthens the argument: India crossed 50% non-fossil installed capacity five years early [6], letting it speak for the Global South from a position of performance rather than pleading.

CBDR-RC thus gives India a principled, consistent and increasingly credible negotiating identity. Going forward, India's task is to pair equity claims with measurable delivery — a grant-based sub-goal within climate finance, mutual recognition of domestic carbon pricing, and a firm forest-sink plan — so that differentiation enables ambition rather than deferring it.
