Business carbon footprint

‘Carbon footprint’ is a term used to describe the amount of greenhouse gas (GHG) emissions caused by a particular activity and thus a way for organisations to assess their contribution to climate change. Understanding these emissions, and where they come from, is necessary in order to effectively manage and reduce them.

WPD produce an annual business carbon footprint for each of our licence areas.  Our business carbon footprint for 2012/13, 2013/14 and 2014/15 is provided below:

Commentary


As shown the greatest annual increase 2013/14 to 2014/15 has occurred in WPD South Wales this was result of a major SF6 leakage event in the Carmarthen area. 

Other minor increases evidenced across all WPD regions are due to;

- Expansion of the number of contractors included within our carbon footprint report
- Better reporting of our depot / office energy usage
- The inclusion of other business areas, for example SURF Telecoms

Business carbon footprint reporting

In order to focus on managing and reducing our emissions over time we have developed a business carbon footprint report which covers the impact of our business operations. The methodology utilised within the report follows UK Carbon Reporting guidance as provided by Defra and is compliant with the principles of the 'Greenhouse Gas Protocol' and the 2014 Guidelines to Defra/DECC's GHG Conversion Factors for Company Reporting.

Fluid filled cable leaks

From March 2014 until April 2015 WPD experienced fluid filled cable leaks (around 1 leak every 18 kilometres) which were all reported to the Environment Agency. All individual leaks have been investigated, repaired and are being remedied.

For above ground spills

A total of 99 incidents were reported to the Environment Agency (Mar 2014 – April 2015) where oil was lost to the environment. It is WPD policy that all above ground spills are contained and cleaned up immediately and additional remedial actions undertaken to ensure minimum pollution to the environment.

Above based upon the global warming potential (GWP) of SF6 = 23,900 (i.e. 1kg of SF6 is equivalent to 23,900kg of CO2) as per Table 5a, Annex 5 of the 2012 Defra Guidelines.

WPD equipment uses 60,599kg of SF6 and this leak rate is around 0.5% per annum, which is in line with expected industry experience.
