Transcript

  • 1. Newcastle: A green case study
  • 2. The Context• City with 292,000 inhabitants, with CO2 emissions of 6.7 tons per capita• At the forefront of economic growth in the North- East, as part of a change from heavy industry to the knowledge and service sectors• UK’s most Sustainable City 2 years running• The national agenda is to reduce carbon dioxide emissions by 34% in 2020, and 80% by 2050.• An ambitious Citywide Climate Change Strategy and action plan• Developed our carbon reduction scenario constrained by nationally produced emissions data
  • 3. Leading change in the Domestic Sector• Retrofitted 40,274 houses, and installed 51,514 insulation measures, resulting in a reduction of 31,369 tonnes of CO2 per annum• Developing a ‘Green Deal’ successor scheme to provide renewable technologies to residents at no cost• Designed a web portal (www.thebiggreenpledge.org.uk) to let residents and businesses unlock our data – let them check energy efficiency of their buildings• Plans to look at suitability for solar p.v./thermal, grants, and see anticipated bills
  • 4. • Changing behaviour – encouraged residents to borrow smart meters from libraries• Running a social marketing pilot to develop new approaches to take up of Loft Insulation• Established a freight quality partnership across the region which aims to create a more efficient and sustainable flow of freight traffic.• £1.7 million project to link 4 tower blocks in Riverside Dene to a biomass system, estimated to reduce carbon emissions by 40-80%• Run a pilot project in Walker to show how social housing can cut energy demands by up to 80%
  • 5. Changing our approach to IT• Designed our environment to deliver efficient architectures and reducing energy consumption (e.g. cloud computing)• Merging the wide-area networks, working with our partners to take 4 networks down to 1, releasing 500KWh per year• Investing in the technology to minimise environmental impact (mobile working, home working)
  • 6. • Reduced server hardware from 540 servers to 208, releasing 6,400kWh p.a.• This will fall to 10 servers over the next 3 years saving a further 1,900 KWh p.a.• Installing a power management platform, expected to release 7,000kWh savings each year• Consolidating regional data centres, reducing our energy consumption by 1,500 KWh per year
  • 7. Transport
  • 8. Some of our future plans• Rolling out the Green Deal scheme to 15,000 households across theNorth East• We will roll out 1,000 domestic p.v. installations and connecting toNational Grid – greening the grid and being paid for it• Embedding carbon values into procurement and investmentdecisions – we currently spend around £400 million p.a. on goods andservices alone• Better use of I.T. to understand and reduce the problem (e.g. vehiclerouting, and spatial distribution of heat, gas and electric use)• This will underpin a number of areas, including economic modellingfor a district Heat Network, reducing climate impacts on services, andmitigating carbon emissions from fleet transport
