Ambition Gap Report

1 July 2023

This landmark report explains in jargon-free terms why the UK’s Net Zero Strategy (NZS) is not bold enough to limit global warming to 1.5°C. The Climate Change Committee is doing a great job highlighting the Delivery Gap, but we need to talk about the Ambition Gap whilst there’s still time to do something about it.

Launched in Westminster at a briefing and Q&A event for MPs and Lords hosted by MPs Caroline Lucas & Hywel Williams on 18th Oct 2022. Press contact: [email protected].

Creating a nature-rich UK

1 September 2023

We have lost our connection to the environment on which we depend for life, polluting it with our waste, with little regard to its sensitivity and extraordinary complexity. We haven’t recognised, until almost too late, that Earth’s natural systems are deeply intertwined, and that as we cross ‘safe’ boundaries, we unleash mutually reinforcing impacts which are shifting our biosphere outside of the stable zone that enabled modern civilisation to develop.
