Ready To Serve Scotland In A Changing Climate
We measure our carbon footprint to understand how much greenhouse gases are emitted by different parts of the business and by different processes. Knowing our carbon footprint allows us to efficiently manage these emissions and to benchmark ourselves against the rest of the water industry.
Over the past six years there have been a number of genuine increases and decreases in our operational emissions. In addition, there have been significant improvements in the collection and allocation of data (such as the inclusion of chemicals for the first time in 2011/12), leading to further changes in the carbon footprint we report.
We have taken the opportunity to ‘re-baseline’ our carbon footprint; revisiting previous years’ figures to take account of data that was unavailable at the time we published them. We have also applied 2011/12 emissions factors to all years in order to see the changes in carbon footprint that arise from genuine changes to our operations.
Our carbon footprint for 2011/12 was measured at 464,990 tCO2e. Like for like (with the re-baselined carbon footprints) this is a reduction in our emissions and continues the trend of the past five years. This is despite continued investment to enhance services, which can impact on our carbon emissions.
Emissions associated with providing drinking water saw a genuine fall of about 10% in 2011/12 as a result of increased energy efficiency, increased generation of renewable energy through our hydro programme and continued leakage management.
On the wastewater side of the business, reductions were also seen in emissions from electricity and natural gas use; the latter may be due to the milder winter experienced in 2011/12 compared with 2010/11.
Further details of our 2011/12 carbon footprint and our re-baselining exercise can be found in our 2012 Sustainability Report.
Scottish Water is committed to managing emissions and to ensuring all parts of our business consider carbon and wider sustainability within decisions and actions. To this end we are currently developing our updated Carbon Management Plan to quantify some of the carbon savings available from the actions laid out in the first iteration of our Carbon Plan.
