What It Is
COP26 (the 26th Conference of the Parties to the UNFCCC) ran 31 October to 12 November 2021 in Glasgow under the UK COP presidency. It was the most consequential COP since the 2015 and produced multiple major outcomes that have shaped climate diplomacy since.
The summit was originally scheduled for 2020 but was postponed by the COVID-19 pandemic. The delay heightened expectations and political pressure on the UK presidency to deliver substantive outcomes.
Key Outcomes
Multiple major outcomes emerged from Glasgow:
The Glasgow Climate Pact
The Glasgow Climate Pact (the cover decision) was the first time a COP cover decision specifically addressed fossil fuels, calling for accelerated efforts toward:
- 'Phasedown of unabated coal power'.
- 'Phase-out of inefficient fossil fuel subsidies'.
The language was watered down from earlier draft text — 'phase-out' at India and China's late insistence — producing 'phase-down' instead. The change was politically charged but the substantive significance remained: the COP system had named fossil fuels for the first time.
Paris Agreement Rulebook Completion
Glasgow completed the Paris Agreement rulebook, including:
- Article 6 carbon market rules: long-stalled rules for international carbon trading and crediting.
- Transparency : detailed reporting requirements for NDCs.
- Common time frames: aligning NDC time horizons across parties.
- Compliance mechanisms: how the Paris implementation system would handle non-compliance.
The rulebook completion was a major institutional achievement — closing the implementation framework that had been opened by the 2015 Paris Agreement.
The Global Methane Pledge
The was launched as a separate — a US-EU initiative committing signatories to reduce methane emissions 30% below 2020 levels by 2030. The Pledge has subsequently grown to 158 country signatories.
The First JETP
The Just Partnership with South Africa was launched as the JETP prototype. The $8.5 billion South Africa JETP became the template for subsequent JETPs with Indonesia, Vietnam, and Senegal.
Finance Commitments
Finance commitments included:
- Doubling adaptation finance by 2025: a commitment to scale adaptation finance.
- Various private-sector and multilateral financial pledges: including the Glasgow Financial Alliance for Net Zero (GFANZ).
- Continued progress toward the $100 billion/year goal.
The Glasgow Ratchet
The 'Glasgow ratchet' agreement to revise NDCs annually was a procedural innovation:
- Pre-Glasgow: NDCs were submitted every five years.
- Glasgow: parties agreed to revisit NDCs annually, with stronger ambition.
- Subsequent implementation: progress has been uneven, with some parties submitting stronger NDCs and others maintaining their existing commitments.
Loss and Damage Deferred
was raised but a dedicated finance facility was deferred to COP27. The Glasgow outcome on loss and damage was widely seen as inadequate — a deferment that ensured loss and damage would dominate COP27 discussions.
The COP27 (2022) decision to establish a was a direct consequence of the Glasgow deferment — developing-country negotiators came to Sharm el-Sheikh determined not to accept further delay.
Why It Matters
COP26 mattered because it:
- Completed the Paris Agreement implementation framework: the rulebook completion was the most important institutional achievement.
- First named fossil fuels in a COP cover decision.
- Launched major sectoral initiatives: Methane Pledge, JETPs, GFANZ.
- Set the stage for subsequent COPs: the Loss and Damage deferment and the Glasgow ratchet shaped subsequent climate diplomacy.
- Tested UK convening capacity: the UK presidency demonstrated that a non-G7-host could deliver substantive climate diplomacy.
Critiques
COP26 faced critiques:
- Insufficient ambition: the cover decision was widely characterized as insufficient relative to climate science.
- Fossil-fuel language compromise: the 'phase-down' vs 'phase-out' change was seen as a major political setback.
- Loss and damage failure: the deferment of L&D finance was widely condemned.
- Implementation gaps: many Glasgow commitments have not been fully implemented.
Common Misconceptions
COP26 is sometimes treated as having 'fixed' climate change. It did not — it advanced the implementation framework but did not produce the emission-reduction commitments needed for Paris-aligned pathways.
Another misconception is that COP26 produced the Loss and Damage Fund. It did not — the Fund was established at COP27 (2022) and operationalized at COP28 (2023). Glasgow only raised L&D as an issue.
Real-World Examples
The Glasgow Climate Pact itself has been cited in subsequent COPs as the foundational text on fossil-fuel language. The implementation through 2022-26 has been substantively important. The South Africa JETP launch has been the template for subsequent JETPs.
Example
COP President Alok Sharma's tearful apology after India's last-minute weakening of 'phase out' to 'phase down' coal language captured the diplomatic drama of COP26's final hours.
