Sign our open letter ahead of COP26

Working with leading scientists, we've identified three, key COP outcomes we can't live without. Will you sign our open letter asking the UK's COP26 team to push for those outcomes?

"Dear PM Boris Johnson, Alok Sharma MP (President of COP26) and George Eustice MP (Environment Secretary). We ask you to follow the science, and push for the following Three COP Outcomes We Can’t Live Without at the climate summit (COP26) in Glasgow in November 2021 and the biodiversity summit (COP15) in Kunming, China in April/May 2022:

COP26 and COP15 must create a joint emergency strategy for getting back within the planet’s safe limits.

This strategy should be rooted in an understanding of how the climate and environmental emergencies are intertwined and together contribute to Earth systems collapse. The parties must think outside their established structures and be creative in integrating their decision-making and governance systems.

The COP26 parties must agree to stick to the remaining global carbon budget that gives us a 66% chance of limiting warming to 1.5°C.

This budget must be allocated fairly on a per capita basis and in keeping with the principle of common but differentiated responsibilities. Every country has to account for its entire carbon footprint – not just the emissions produced on its own soil, as is currently the case. All countries need individual carbon budgets, which add up to the total remaining global carbon budget.

The Global Biodiversity Framework on the table at COP15 must include a global goal to go nature positive by 2030.

This means that by the end of the decade, we must be achieving net gains in biodiversity against a baseline of 2020. Countries must commit to taking responsibility for their entire ecological footprint, not just their impact on nature within their own borders. This goal must be supported by a well-resourced implementation framework, which integrates biodiversity commitments across all sectors of society, and can be used for coordinating, prioritising and tracking the responsibilities and contributions of different stakeholders towards a net-positive goal.
