Greenhouse Gas Emissions: Yorkshire and Humberside Hugh Bayley To ask the Secretary of State for Environment, Food and Rural Affairs what the change in greenhouse gas emissions has been in percentage terms in (a) Yorkshire and the Humber and (b) City of York since 2003. Joan Ruddock DEFRA does not hold greenhouse gas emissions data at the geographical level necessary to derive these reductions. Experimental local authority carbon dioxide emissions data are currently available for 2003 and 2004 only— however, due to changes in the underlying methodology, year-on-year comparisons using these data would be inappropriate. I have placed experimental emissions estimates for 2003 and 2004 in the Library of the House.
