Sainsbury's crewe energy

Goal: In our own operations, reduce CO2 emissions from energy for building services through responsible energy sourcing, minimising demand and efficient consumption.
The majority of the Group energy use is in the operation of the supermarket stores. Energy is used to run the store (e.g. heating, lighting and refrigeration) with refrigeration using the most energy as the proportion of fresh food sold grows. This involves the consumption of fossil fuels, releasing carbon dioxide (CO2).
We recognise the need to tackle our contribution to global warming. We are focusing on energy efficiency and buying energy from sources with lower CO2 emissions.
Energy Programme
Sainsbury's Supermarkets uses the most energy of the companies in the Group. Sainsbury's Supermarkets is currently undertaking a major store refurbishment programme and is running initiatives to improve energy efficiency. Examples of its energy programme include:Energy efficiency:
A £14.5 million capital investment programme singularly focused on energy reduction projects has now started. Installations on various stores changing lighting, refrigeration and supply voltages is reducing total electricity usage by 2-20% per site.
Stores are targeted with energy usage, and their progress monitored. There is a company intranet site with specific information to support stores by monitoring and managing results.
A "Save It" campaign in stores encourages colleagues to switch off equipment when it's not being used, close cold store doors and switch off lights.
Control systems are being checked and updated to ensure stores use energy as efficiently as possible.
As part of the company's Climate Change Levy Agreement with DEFRA, an in store bakery target has been agreed to ensure steady reduction in CO2 emissions reductions until 2010.Renewable energy:
Sainsbury's Supermarkets uses renewable energy where financially feasible. Currently a number of initiatives are being trialled:
A wind turbine is in operation at East Kilbride depot providing a proportion of the depot's energy requirements depending on wind speed. Small wind turbines are also fitted at Greenwich and Kingston-upon-Thames stores.
Combined Heat and Power (CHP) is being used in six stores, improving the energy output and efficiency of fossil fuels - providing both heat and electricity to the stores.
Solar panels and natural lighting are also used in Greenwich store.

Notes to Graph
Sainsbury's Supermarkets data
2001/02- 2002/03
Data do not include Sainsbury's Local stores, which account for less than 1% of floor area and a similar proportion of total energy used.
Gas data are taken from meter readings and from estimates where necessary.
2000/01-2001/02
Sainsbury's Supermarkets: basis of calculation for 2000/01 used actual energy data, rather than a mix of audited bill data and average unit cost. Over 98% of data are complete, remaining data are estimated.
Sainsbury's Supermarkets conversion factors were taken from DETR Environment Reporting Guidelines (1999):Electricity 0.44kg CO2/UK kWhNatural Gas 0.19kg CO2/UK kWh
In previous years Sainsbury's Supermarkets data were in financial periods. From April 1 2000 energy data are reported in 12 months from 1 April to 31 March.
1997/98 -1999/2000
Energy consumption data were based on audited accounts, and where data were missing, estimates were made.
Conversion factors have also been changed to use those from the DETR for the three years 1997/98 to 1999/2000.
Due to organisational restructuring the data for 1997/98 and 1998/99 were amended to be consistent with the data collecting methodology used in 1999/2000.
Shaw's data
The data are for Shaw's supermarkets stores only.
The data for 2000/01 did not include Grand Union stores.
Data for 1999/2000 refer to period 1 January to 31 December 1999. Succeeding years relate to periods from 1 March to 28 February. For U.S. data purposes, 1 ton equals 2000 lbs.
Shaw's conversion factors from US Environment Protection Agency guidelines: Electricity 1.1lbs CO2/kWh (0.499kg CO2/kWh) Natural Gas 0.19kg CO2/kWh.
Data for 2000/01 restated from last year's report but not subject to independent review.
Sales areas for both Sainsbury's Supermarkets and Shaw's have been taken from the J Sainsbury plc Annual Report and Accounts 2003.
Overall PerformanceSainsbury's Supermarkets Performance
Overall CO2 emissions from store energy usage declined by 2.6% during the year and are now 5.8% below the baseline year of 1997/98. This improvement in performance has been due to a combination of projects including the start of our Energy Projects Agreement (EPA) with our energy supplier, RWE, which includes a £14.5 million capital investment in energy saving installations, our energy awareness campaign "Save It" and our Climate Change Agreement reducing consumption in in-store bakeries. With the current savings achieved from our EPA we are confident of meeting our long-term goal of reducing CO2 emissions by 10% in 2005.Shaw's Stores Performance
Overall CO2 emissions from store energy rose 5.6% in total (4.5% relative to floor area) during 2002/03. This was due to a particularly cold winter and a warmer than usual summer. Heating degree days (where mean temperature is below 65°F (18°C)), rose by 30% during the winter and cooling degree days (where mean temperature is above 65°F) rose by 16%.
Seven additional Energy Star labels were obtained during the year. This means that there is at least one Shaw's store with an Energy Star label in each of the New England states. In addition to further the commitment to purchasing renewable energy, renewable energy credits have been purchased for three stores in Rhode Island to assist customers to invest in clean energy for their local neighbourhoods.
