New York, 30 October 2026 — Carbon credit markets may not be aligned with countries’ international obligations on climate change and human rights, a new United Nations report warns, calling for an urgent reassessment of a tool used by the vast majority of countries.
The report, “Rethinking carbon credits according to international climate and human rights obligations” (A/81/217), was written by Elisa Morgera, the UN Special Rapporteur on the promotion and protection of human rights in the context of climate change, for the 81st session of the UN General Assembly. The UN human rights office published its findings on 29 October 2026.
What the report found
According to the report, research, court decisions and the lived experiences of communities show that carbon credit mechanisms incentivise low-quality credits, over-crediting and greenwashing, resulting in delayed emissions reductions. Each carbon credit is meant to represent one tonne of carbon dioxide equivalent reduced or removed — but the report argues that the equivalence between different kinds of emissions is often flawed.
“As the vast majority of countries rely on carbon credits, we cannot ignore the evidence casting serious doubt about the effective contribution of international carbon credit markets to climate mitigation,” Morgera said.
“As far as carbon markets contribute to increased greenhouse gas emissions, they harm everyone’s human right to a healthy environment, including for children and future generations,” she added.
Harm described as systemic, not isolated
The report states that the widely documented negative impacts of carbon credit projects on the human rights of Indigenous Peoples, peasants and rural women are not isolated implementation failures, but systemic issues rooted in the design of the markets and the incentives they create.
It further warns that the economic actors benefiting most from international carbon credit markets are those with a vested interest in the continuation of a fossil fuel-based economy, including big technology companies. “Any form of international cooperation, including carbon credits, cannot assist or benefit climate-harming economic actors, particularly when these same actors engage in climate disinformation and obstruction,” Morgera said.
The report also cites concern about the unchecked growth of data centres and artificial intelligence, and the UN Secretary-General’s call for polluters to pay for climate harm rather than continue making large profits from it.
What happens next
Morgera calls for an urgent reassessment of carbon credits — internationally and domestically — in line with the International Court of Justice’s advisory opinion on states’ climate obligations. Technical reforms currently discussed under the Paris Agreement, she argues, may be insufficient to address the structural problems identified.
The warning lands just ahead of COP31 in Antalya in November 2026, where carbon market rules under Article 6 of the Paris Agreement remain part of the negotiation agenda. The report does not call for abandoning international cooperation on climate; it argues that cooperation must not benefit actors that harm the climate.
