COP26: the Glasgow Climate Pact and what it changed
COP26, held in Glasgow in October and November 2021, was presented as a decisive moment for keeping the 1.5°C temperature limit within reach. The conference ended with the adoption of the Glasgow Climate Pact and the completion of important parts of the Paris Agreement Rulebook. The outcome advanced international cooperation, but it did not close the gap between announced targets and the emissions reductions required.
Four areas of action
The UK Presidency organised its objectives around mitigation, adaptation, finance and collaboration. This framework helps explain both the formal decisions and the parallel commitments announced by governments and other participants.
1. Mitigation and the unprecedented reference to coal
The Pact called on countries to strengthen their 2030 targets and accelerate emissions reductions. For the first time, a final COP decision explicitly referred to the phasedown of unabated coal power and the phase-out of inefficient fossil-fuel subsidies. The final wording was weaker than the original proposal to phase out coal, reflecting the political compromise needed to reach consensus.
2. Adaptation, resilience, and loss and damage
The agreement gave greater attention to adaptation and urged developed countries to double collective adaptation finance by 2025, relative to 2019 levels. It also advanced work on the Global Goal on Adaptation. On loss and damage, however, the outcome fell short of the expectations of many vulnerable countries: a dialogue on funding arrangements was established, but no dedicated funding mechanism was created at that point.
3. Climate finance
Developed countries reaffirmed the commitment to mobilise USD 100 billion per year to support developing countries. The pledge, originally expected to be met in 2020, had still not been delivered when the conference ended. The Pact recognised the need for greater support but did not immediately provide the promised resources.
4. Rules and transparency
COP26 concluded important negotiations on the Paris Agreement Rulebook. Parties agreed guidance for transparent reporting of climate action and rules for market mechanisms and non-market approaches under Article 6. These rules matter for environmental integrity, accounting for emissions reductions and avoiding double counting.
What COP26 did not resolve
The Pact retained 1.5°C as the guiding temperature goal, but the policies and commitments presented at the time did not, by themselves, guarantee a pathway consistent with it. Negotiated wording, insufficient finance and the lack of a robust solution for loss and damage demonstrated the limits of multilateral consensus.
COP26 should therefore be understood as a step in implementing the Paris Agreement, not as a solution to the climate crisis. Its legacy includes more complete rules and important political signals, but results depend on turning pledges into policies, investment, actual emissions reductions and support for the countries most exposed to climate impacts.
Why this matters to business and LCA
National targets and sectoral policies change the conditions under which companies produce goods, procure energy, select materials and organise supply chains. Life Cycle Assessment (LCA) can support decisions by identifying where impacts occur and helping avoid shifting environmental burdens from one stage to another.
LCA does not replace national greenhouse-gas inventories, macroeconomic scenarios or public-policy assessments. It is a complementary tool for evaluating products, services and systems from a life-cycle perspective.
The key lesson from Glasgow: international agreements establish direction and rules; their effectiveness depends on verifiable implementation over time.
