Our carbon footprint
While sales grew by 10.6%, our total emissions only increased by 4.7%, to 541,956 tonnes in 2010/11. This equates to a 5.3% reduction in carbon dioxide equivalent (CO2e) emissions on a normalised basis per £m sales. Much of the increase in absolute emissions is due to improving our emissions coverage: we have included water supply, water treatment and other fuels used in buildings in our 2010/11 baseline.
The diagram (below) shows the boundary and emissions scopes for our carbon reduction target. It includes emissions resulting from UK-operated parts of the business and significant emissions from third-party sites used exclusively by Waitrose. It excludes potential emissions reductions from green tariff electricity or project-related emissions reductions (offsets).
We continually work to improve the data quality and granularity for the emissions sources we currently report on. For example, since our last report, we have installed automatic meter readers in our shops, which provide accurate and timely data to support better energy management.
We participate in the Government’s Carbon Reduction Commitment (CRC) Energy Efficiency Scheme by monitoring and reporting carbon emissions associated with building energy use. We are also a founding member of the Freight Transport Association’s Logistics Carbon Reduction Scheme for transport emissions.
