Mandatory GHG Reporting 2015

BAE Systems has published a breakdown of our GHG emissions in our Annual Report 2015.

The majority of our greenhouse gas emissions come from the energy we use across our facilities. The Group’s greenhouse gas emissions2 increased by 1% in 2015 largely due to increased activity at some of our larger sites. This includes the bi-annual running of a high-energy test facility at Barrow-in-Furness, UK, and diesel usage for sea trials of the Landing Helicopter Dock in Australia.

The greenhouse gas emissions data is reported in line with the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard ‘Operational Control’ method, and emission factors for fuels and electricity are taken from the UK government’s Department for Environment Food & Rural Affairs (DEFRA), published at
The CO2e associated with carbon dioxide, methane and nitrous oxide is reported. Greenhouse gas emissions associated with hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride are estimated to be immaterial to total emissions and are, therefore, not reported.
The principal record of the Group’s worldwide facilities is its legal department’s Global Property Database.
Greenhouse gas emissions are primarily calculated from energy consumption records reported via the Group’s global environmental database. Where actual usage data is not available for facilities and residences within the Global Property Database, an estimated consumption is used based on the type of building.
Greenhouse gas emissions related to business travel include air travel data for the majority of the global business and rail data for business units operating in the UK and US. These data are taken from suppliers’ procurement records.
Emissions from joint ventures and pension scheme properties not occupied by the Group are not included.
