Examine the principle of Common But Differentiated Responsibilities (CBDR-RC) and evaluate whether the current climate blame discourse is equitable to developing nations.

Enshrined in UNFCCC Article 3 and reaffirmed in the Paris Agreement preamble, CBDR-RC holds that while climate protection is a shared duty, obligations must differ according to historical contribution to atmospheric stock and present capability. It remains the doctrinal core of India's negotiating stance.

Content of the principle

• Common responsibility: the atmosphere is a global commons; all parties must act, which is why India files NDCs despite low historical emissions [2].
• Differentiation: developed nations, having caused the bulk of cumulative emissions, must lead in mitigation, finance and technology transfer.
• Respective capabilities: obligations scale with economic capacity — recognising that developing countries face competing demands of poverty eradication and energy access.

Why the blame discourse is inequitable

• Per capita reality: India's per capita emissions are less than half the global average, while developed countries' are several times higher [1]; UNEP itself notes India has the lowest per capita emissions among major economies [5].
• Delivery record: India met its emission-intensity target (36% cut, 2005-20) and reached 52.57% non-fossil installed capacity by February 2026, both years ahead of schedule, and has enhanced its 2035 NDC to a 47% intensity cut and 60% non-fossil capacity [1][2].
• Unmet finance promise: the COP29 (Baku) goal of $300 billion a year by 2035 fell far short of the $1.3 trillion sought; India's negotiator called it a "paltry sum" [4]. Blame without finance shifts burden, not responsibility.

Where the discourse has some force

• Developing economies now drive the largest absolute increments in emissions [5], and with UNEP's Limiting Overshoot warning of a 1.5°C breach within a few years [3], future mitigation is decided largely in Asia.
• India's carbon sink target (2.29 bn tonnes CO₂eq achieved, 2005-21) still lags its 2.5-3 bn tonne goal [1][2].

CBDR-RC therefore remains equitable in principle; what is inequitable is its selective application — demanding ambition from the South while under-delivering finance. The way forward lies in India pairing credible domestic delivery, especially in forestry and generation-side decarbonisation, with Himalayan adaptation cooperation, so that climate justice is claimed through performance rather than pleaded through history.
