Departments: Carbon Emissions

Volume 461: debated on Thursday 14 June 2007

To ask the Secretary of State for Northern Ireland what methodology is used by his Department to account for its carbon emissions. (140796)

Carbon emissions from the NIO’s estate are calculated from energy data supplied by the NIO Energy Manager to Energy Branch in the Department of Finance and Personnel, which collates such data for all public sector bodies in Northern Ireland for publication in the annual Public Sector Energy Campaign Report. They use the following conversion factors (similar to those used by DEFRA) to calculate carbon emissions:

Grammes per kWh

Electricity

430

Gas/diesel oil

250

Natural gas

190

Liquid propane gas

230

Heavy fuel oil

260

The Department also participates in the Government Carbon Offsetting Fund, which aims to offset emissions from air travel. The emissions are calculated as follows:

For short haul each km flown equals 0.3kg CO2

For long haul each km flown equals 0.22kg CO2
