COP1 Berlin

COP1 Berlin was the inaugural Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), held from 28 March to 7 April 1995 in Berlin, Germany. It convened roughly a year after the UNFCCC entered into force in March 1994, bringing together delegations from the treaty's parties to begin the formal intergovernmental process of implementing the Convention.

The summit was chaired by Angela Merkel, then Germany's Federal Minister for the Environment, Nature Conservation and Nuclear Safety. Its central outcome was the Berlin Mandate, which acknowledged that the existing commitments under the UNFCCC — calling on developed countries to aim to return greenhouse gas emissions to 1990 levels by 2000 — were inadequate to meet the Convention's objective of preventing dangerous anthropogenic interference with the climate system.

The Berlin Mandate launched a negotiating process to strengthen developed-country commitments by adopting a protocol or other legal instrument. Crucially, it preserved the principle of common but differentiated responsibilities (CBDR) by explicitly not introducing new commitments for developing countries (Non-Annex I parties) during this round. This negotiating track, conducted through the Ad Hoc Group on the Berlin Mandate (AGBM), culminated two and a half years later in the adoption of the Kyoto Protocol at COP3 in December 1997.

Other decisions taken at COP1 included:

• Establishing the Subsidiary Body for Scientific and Technological Advice (SBSTA) and the Subsidiary Body for Implementation (SBI) as permanent organs of the COP.
• Launching a pilot phase for Activities Implemented Jointly (AIJ), an early precursor to later flexibility mechanisms such as Joint Implementation and the Clean Development Mechanism.
• Selecting Bonn as the seat of the UNFCCC Secretariat.

COP1 is widely regarded as the political starting point of binding climate diplomacy, distinguishing the UNFCCC's aspirational framework from the rule-based regime that emerged at Kyoto and was later restructured by the 2015 Paris Agreement at COP21.
