London, United Kingdom (11 February, 2011) – DNV, a leading international provider of risk management and quality certification services, recently verified Heathrow Airport’s Scope 3 carbon emissions under the Airport Carbon Accreditation scheme.

Introduced in June 2009, the scheme aims to provide a framework for assessing carbon emissions from airports, as well as reducing emissions associated with their operations. The scheme’s ultimate goal is to achieve carbon neutrality (zero net emissions) and is completely voluntary. A major aspect of the scheme is major annual carbon footprint verification for participating airports, which are carried out independently by a third party.

The scheme uses the principles of the Greenhouse Gas (GHG) Protocol, ISO 14064, to identify the source of CO2 emissions under 3 scopes:  All direct GHG emissions from the airport, such as (Scope 1); Indirect GHG emissions from consumption of purchased electricity, heat or steam (Scope 2);  and emissions associated with the airport which can be influenced, but are not under the direct control of the organisation, such as emissions generated by passenger transport and the take-off and landing flight paths of aircraft using the airport (Scope 3). The Scope 3 emissions account for the largest percentage (83%) of the total carbon footprint at Heathrow.

“The participation Heathrow have shown in this scheme is a positive indication that airports want to managing and reducing their carbon emissions,” commented John Pepper of DNV. “The scheme is flexible enough to let airports use surveys and other forms of data collection to estimate their emissions rate. This is an essential element of scope 3 reporting, which has to also include indirect carbon emissions. So far, approximately 20 airports have signed up to the scheme, while another 420 may potentially join, which would be fantastic.”
