What is The Trillion Tonne Communiqué?

The Trillion Tonne Communiqué is a global call to arms from businesses who take the science of climate change seriously and are demanding a proactive policy response.

The latest report from the Intergovernmental Panel on Climate Change (IPCC) sets out the link between the cumulative total of greenhouse gases in the atmosphere and the resultant global climate change. It warns that if atmospheric emissions exceed more than a trillion tonnes of carbon from CO2 then the global average temperature increase is likely to exceed 2°C.

The risks of this level of climate change are too significant to ignore and The Communiqué draws out the implications of this by identifying three clear goals that a policy framework that keeps cumulative emissions below a trillion tonnes will need to deliver on. These goals have been chosen because of their ability to clarify the scale and nature of the transformation required.

Over 1,000 companies from more than 60 countries have signed up to at least one previous Communiqué. Please sign The Trillion Tonne Communiqué and join the growing number of influential business leaders showing support for an urgent and robust policy response to climate change.

Who Produced The Trillion Tonne Communiqué?

The Trillion Tonne Communiqué has been developed by The Prince of Wales’s Corporate Leaders Group (CLG); a group of UK, EU and international progressive businesses who believe that there is an urgent need to develop new and longer term policies for tackling climate change. This Communiqué builds on the foundations of the previous Communiqués, all created by the CLG and managed and developed by the University of Cambridge Institute for Sustainability Leadership.
