The Environment Agency regulates about half of the UK’s greenhouse gas emissions
UK greenhouse gas emissions As the slide shows we regulate emissions from industry and service sectors. These roles provide us with a strong basis work with businesses we regulate to help them achieve energy efficiency improvements We will have a role in advising businesses on energy efficiency improvements as part of our site inspection work but we can also point them towards expert help and support, for example from the Carbon Trust We must also continue to run the CRC and EU ETS efficiently in order that businesses can achieve these emissions at least cost The future of these schemes – their coverage and the level of caps set will be crucial to achieving our national targets – we have a responsibility to use our operational knowledge to advise Government on how these schemes should develop

On the other side of climate change we also have a key role in reducing vulnerability and risks so we are resilient to future impacts (adaptation). As we are already “locked” into a temperature rise of at least 2 degrees by the 2030s, planning for adaptation is essential. Our new Adaptation Strategy sets out a programme of adaptation until 2011 We are responsible for a number of areas that are critical in adapting to climate change in England and Wales, for example: Coastal erosion Flood risk Water resources Impacts on freshwater species Adaptation action plans exist for all our work, from flood risk management and water resources to agriculture and waste. The challenge is to embed thinking about climate change into all our work and decisions.

We are an environmental regulator of low carbon energy technologies If we are to meet our emissions targets by 2020, around 40 percent of electricity will be from low-carbon sources. The Committee on Climate Change has recommended that by 2030 we should almost fully decarbonise our electricity supply (DECC) Low Carbon technologies we regulate include for example: Marine Energy and Hydropower (top left photo) – e.g. Severn Tidal Power Scheme currently at feasibility stage. This has potential to provide 5% of UK electricity. We have to balance carbon savings against other environmental impacts. We also expect well over 1000 more smaller hydropower schemes to be built by 2020. Nuclear (top right – Oldbury) - New builds planned to meet Govt emissions targets. EA role is to help ensure that new nuclear meets high standards of safety, security, environment protection and waste management. As a regulator, we do not take a position for or against. Landfills (bottom right) - We regulate and monitor methane emissions (a type of greenhouse gas) Carbon capture and storage (bottom left) - technology to capture carbon during power generation and remove it before it is emitted. We are likely to be the regulators of CCS and be tasked with making judgements on when technology is ready to be rolled out. (We also have roles in Biomass– energy from plant and animal material, Combined Heat & Power Generation (from biomass or waste), and Anaerobic digestion - energy from decomposition of organic waste (less landfill, less methane)).

Mires are peatland habitats - Such as Blanket bogs, Valley bogs and Fens all of which occur in the Exmoor National Park. Blanket bog is a globally scarce habitat; 20% of the total world resource occurs in the UK. Peat is extremely beneficial, in three principal ways. Firstly, it stores huge quantities of carbon. Natural England estimates that the amount of carbon stored in UK peat bogs would, if released to the atmosphere, equate to five billion tonnes (equivalent to nine months’ global greenhouse gas emissions). Secondly, peat holds enormous quantities of water. This slows down water run-off during and after heavy rainfall. This is becoming increasingly important in flood protection as our climate changes. Thirdly, the slower water run-off helps to prevent nutrients, suspended solids and organic matter from entering rivers and streams, which improves their quality. Moss is 95% water.
