Conference of the Parties (COP) and DLA Piper

At the 1992 Earth Summit in Rio de Janeiro, the United Nations Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity (CBD) were opened for signature, while the summit outcome called for negotiation of the United Nations Convention to Combat Desertification (UNCCD).

The Conferences of the Parties (COPs) to these three Rio Conventions serve as the main decision-making forums for setting global environmental and nature policy and addressing climate-related issues. These Conferences have initiated regulatory shifts, shaped supply chain risks, guided financial flows, and influenced global markets and investment trends.

• Negotiations at the UNFCCC COP – or the Climate COP – aim to drive international climate action, shape policies related to reducing greenhouse gas emissions, enhance adaptation efforts, and mobilise climate finance.
• Dialogues held under the CBD COP – or the Biodiversity COP – set targets for protecting ecosystems, conserving species, and ensuring the sustainable use of biodiversity.
• At the UNCCD COP – or the Desertification COP – parties discuss land degradation, sustainable land management, and actions to combat desertification, which can impact food security, ecosystem resilience, and climate change.

DLA Piper has been advising governments on a pro bono basis at the Climate COP since 2012, the Biodiversity COP since 2022, and the Desertification COP since 2024. In each COP, we have helped governments interpret complex legal and treaty texts and effectively navigate the negotiations.

Our recent work is as follows:

• Climate COP 30 (2025): We continued negotiation support for a developing country in the Blue Zone, whilst hosting closed door events for senior leaders and voices in the sustainability space, with a particular focus on adaptation, resilience, the energy transition and carbon markets.
• Climate COP 29, Biodiversity COP 16, Desertification COP 16 (2024): We represented states in the negotiations at all three COPs in 2024, providing support in the Blue Zone (the accredited formal negotiation space managed by the UN) at the Biodiversity COP in Cali, the Climate COP in Baku, and the Desertification COP in Riyadh.
• Climate COP 28 (2023): We continued negotiation support for a developing country and a Small Island Developing State, focusing on emissions reduction and renewable energy projects. We further participated in various events and panels, where we addressed such topics as sustainability data, global plastic regulations, and financing the green energy transition.
• Biodiversity COP 15 (2022): We provided legal support to the government of a Small Island Developing State, addressing key biodiversity issues. We further briefed government representatives on technical issues.
• Climate COP 27 (2022): We advised the Egyptian Ministry of Electricity and Renewable Energy, as well as negotiated on behalf of a developing country. Our Partners spoke on panels related to sustainable ocean business and clean energy finance.
• Climate COP 26 (2021): The UK government appointed DLA Piper as their Provider of Legal Services, through which we helped bolster the country’s commitment to the UN Race to Zero Campaign. We further negotiated on behalf of a developing country.
