Presentation Overview

• Brief Overview of UU • The impact of climate change of the provision of water services • Adaptation – the impact on our activities and our response • Mitigation – our strategy and plan 2

Water and Climate Change – a starting point

“The economy is a wholly owned subsidiary of the environment”

Herman Daly, 2005

“The effects of climate change will be felt everywhere …In the UK the effects will be mainly mediated through water, with increases in the number of both flood and drought incidents expected”

H.M Treasury 2006

How Climate Change will impact the north west – water services

• Wetter winters with more intense rainfall • Hotter and drier summers but with intense rainfall • Longer droughts, more severe droughts and more frequent droughts Thirlmere Reservoir, Lake District 6

Responding to the impact on our activities - water

2035 estimate – shortfall in supply of some 10% or around 200 million litres of water every day Measures to address this: • Reduce demand for water (leakage control and customer efficiency) • Increase supply of water (small scale new resource development and greater network integration) • Key proposal is the East-West link to move water from Prescot to Bury linking Lake District and Welsh sources 7

How Climate Change will impact the north west – wastewater services

Carlisle Wastewater Treatment Works – January 2005 • Increased flooding incidences • Increased CSO discharges • Reduced final effluent discharge dilution • Increased blockages 8

Responding to the impact on our activities - wastewater

Green roofs (above) and detention ponds (below) Traditional approach, to build our way out of this problem, will not work. Focus must be on: – Education – awareness that flooding can not be eliminated but must be managed, – Make public true levels of risk of flooding from all sources – Planning input – mandatory that all new development be drained on a sustainable basis e.g. green roofs, rainwater recycling, SUDS – Responsibility – Reduce the number of stakeholders involved in urban drainage to 2 – the regulator and a single operator 9

Planning Our Response

• Adaptation - a long term problem that demands a long term answer • Planning for its consequences needs to begin right now • We are including our intentions in our regulatory plans for 2010 to 2015 .

• These plans will be influenced by the UKCIP rainfall scenarios to be released next year 10

UU’s carbon strategy and plan

There are four key strands to our carbon management strategy: • Seeking to achieve a net 5% reduction on the 2005/06 baseline for our “owned” carbon emissions by 2012 (with projected rises this is actually a reduction of 8% overall) • Continuing our reduction of emissions beyond 2012 in line with the long-term government targets set for 2050 • Influencing the external environment to support the achievement of these aims • Pursuing a vision of making carbon an integral part of the way we do business But what is the context for setting this direction?

Providing context – UU’s carbon footprint

• • 2006/7 emissions - directly responsible for 472 thousand tonnes of CO2 equivalent using one-third of one per cent of all UK electricity A further 1.57 million tonnes that we don’t directly own but can have an influence over. 20% UU-owned emissions split by source 1% 3% 4% Net Grid Electricity Consumption Process Emissions Other Fuel use Transport Fuels Rail and Air Travel 72% 12

Providing context – emission projections

Year

Actual carbon emissions (1990-2005) and projections to 2020 Linear reduction of 60% from 1990 baseline Impact of mitigation activities to 2020 • UU’s operational carbon footprint has nearly doubled since 1990 • This is a direct consequence of £10 billion of investment in assets to deliver environmental and customer improvements 13

Delivering our carbon strategy – to 2012

Delivery of one 2.4 MW CHP engine to Davyhulme WwTW • • A 8% gross reduction in CO2e emissions by 2012 • • • £22m investment in increasing CHP yield by 80% UU home to one quarter of all sewage gas CHP sites (23 in total) Improving pump energy efficiency 18% reduction through green energy supply contracts 14

UU’s (and the industry’s) challenge – the journey to 2050 and a 60% reduction

488,000 tCO 2 e

CHP and IPM = 38,000 tCO2e Cost = £37m Wind = 80,000 tCO2e Cost = £80m Low carbon technology = 80,000 tCO2e Cost = £??

170,000 tCO2e = TBD

• UU carbon emissions baseline (2005/6) 488,000 tCO 2 e • Climate Change Bill targets 60% reduction on 1990 levels by 2050 • For UU, this equates to 122,000 tCO 2 e • To meet that target equals a reduction of 366,000 tCO 2 e • The diagram illustrates what abatement strategies could be adopted, with what impact and at what price 122,000 tCO 2 e 15

Delivering our carbon strategy – to 2050

• On the journey to 2050, aim to halve owned emissions from current levels by 2035 • require energy neutrality in wastewater operations • reduced pumping in water network • tackle problems at source • appropriate financial instruments • on-going research into renewable generation and low carbon technology • promoting water efficiency 16

Delivering Our Strategy through influencing others – our customers

• For customers, making the link in the minds of our customers that there is a carbon footprint associated with the provision and use of water – Reduced heating of water (about 8 x water cycle footprint) • • Power Shower Study joint project with Liverpool John Moores University electric showers better than mixer or pumped showers water saving showerheads Better information 17

Delivering our strategy – stakeholder challenges

• For Ofwat and the Environment Agency, crucial to strike the balance between the on-going delivery of aquatic environmental improvements and the airborne (i.e. carbon) consequence • For Ofwat, creating the framework to encourage investment in greenhouse gas mitigation – Financial instruments such as incentives – Minimising the impact of the enhancement programme – Reducing the footprint of the existing assets/maximising energy recovery 18

Delivering our strategy – the role of employees

• Employee engagement is crucial to change behaviour • Our employees can provide many ideas on reducing carbon emissions • Changed business processes are needed to embed carbon into decision making e.g. inclusion of cost of carbon into PR09 planning • Sector first in appointing full-time Carbon Manager to lead plan delivery • Carbon communications plan (both internal and external) in place to promote our carbon management agenda 19
