Independent assurance statement continued<br />

Improvements and recommendations<br />

The following is a summary of the key areas for comment and<br />

improvement, highlighted within the scope of this assurance:<br />

• The airport should continue to look at a range of options<br />

for reducing energy consumption. While the Biomass boiler<br />

provides an excellent source of energy for the site; we would<br />

encourage the airport to continue to review other renewable<br />

energy sources in line with the recent energy strategy<br />

• In addition, as part of a wider energy management<br />

programme, we would encourage the airport to install<br />

further energy meters to improve their understanding of<br />

where energy is being used, especially the split between<br />

<strong>London</strong> <strong>Stansted</strong> and tenants consumption. This will assist<br />

the airport in reducing any double counting in <strong>report</strong>ing<br />

• It is recommended that the airport considers new<br />

approaches to dealing with the Category 1 waste from<br />

long haul flights, currently sent to landfill. This is particularly<br />

important if long haul flights at the airport increase<br />

• As <strong>London</strong> <strong>Stansted</strong> prepares for greater autonomy within<br />

the BAA operating Group, it is recommended that efforts<br />

are made to develop airport-specific data sources in some<br />

cases in order to improve the accuracy of the footprint. This<br />

particularly applies to the calculation of aircraft emissions in<br />

the annual carbon footprint<br />

• <strong>London</strong> <strong>Stansted</strong> relies on third parties for the provision<br />

of data, principally relating to waste disposal and scope 3<br />

CO 2 emissions. Due to the limited control that the airport<br />

has over this data, it is important that data owners fully<br />

understand any assumptions and that they are regularly<br />

revisited to ensure their relevance. It is recommended that<br />

the airport carry out spot-checks or audits on this data to<br />

ensure accuracy<br />

• The carbon footprint has highlighted that while current data<br />

collection methodologies are robust and comprehensive,<br />

they may not be provided in a form that makes the<br />

identification of reduction strategies easy to determine and<br />

it is recommended that the methodologies are reviewed.<br />

Our assurance opinion<br />

Based on our assurance, our opinion is that the Sustainability<br />

Report 2010 for <strong>London</strong> <strong>Stansted</strong> provides a detailed and<br />

accurate representation of their activities for the period 1<br />

January 2010 to 31 December 2010. The Carbon Footprint<br />

for 2010 for the airport presents a fair representation of the<br />

GHG data and has been prepared in accordance with the<br />

GHG Protocol.<br />
