Climate change is the single biggest risk facing the planet according to the 2021 Intergovernmental Panel on Climate Change (IPCC).
Our Group businesses are already experiencing many climate change impacts, and these are expected to increase, with temperatures anticipated to be at least 1.5°-2°C this century. Addressing climate change is not just a global issue, local impacts will be felt, and local action needs to be taken. Our region is particularly vulnerable to climate change as we have 1,384km of coastline, and our proximity to the Atlantic Ocean means our area is exposed to impacts from rising sea levels and storm intensity.
Future trends for the South West show that by 2050 we could see a 3°C increase in average summer daily temperatures, with a 5°C increase by 2080, rainfall will become more variable with much drier summers and a fivefold increase in heavy rainfall events and by the end of the century sea levels are predicted to be 0.5-0.8m higher than they are today.
Climate adaptation
Assessing climate change risk and any potential impacts and possible mitigations on our various operations, assets and networks, is an ongoing process.
In December 2024, we published our latest climate change adaptation report as part of the UK government’s fourth adaptation reporting cycle. This feeds into the next UK Climate Change Risk Assessment and National Adaptation Programme and details what actions we are undertaking to ensure that we are adapting to any emerging climate change risks.
We have already made good progress in mitigating the impacts of climate change, but in response as risks develop over time we need to continually monitor and review our plans. Collectively these plans are driven through:
- South West Water and Bristol Water - Water Resource Management Plans for the next 25 years.
- South West Water - Drainage and Waste Water Management Plan for the next 25 years.
- South West Water and Bristol Water - five-year business plan covering the period 2025-2030.
Copies of these plans can be found on our company websites.
For further details of how our business is preparing for climate change please see our latest Climate Change Adaptation Report
We are core members of the Water Resources West Country Water Resources group, established in 2017 to allow improved collaboration in water resources management in the South West of England.
Task Force on Climate-related Financial Disclosures’ (TCFD)
TCFD provides a framework setting out how businesses should integrate climate change risk and opportunities into their business strategy, governance, risk management and metrics and targets. Pennon support the Financial Stability Board Task Force on Climate-related Financial Disclosures’ (TCFD) recommendations that were introduced as mandatory reporting for 2022.
