Global Warming (Hansard, 29 April 2002)

§ Mr. Carmichael
To ask the Secretary of State for Environment, Food and Rural Affairs what the emissions figures are for each of the Kyoto protocol greenhouse gases in every year since 1997; and what different weighting is given to each gas owing to its global warming potential. [51962]

§ Mr. Meacher
UK emissions data for the six greenhouse gases covered by the Kyoto protocol to the year 2000 were reported to the United Nations Framework Convention on Climate Change earlier this month.
550W
The following table summarises the data for the years since 1997, expressed in million tonnes of carbon equivalent. The global warming potential used to arrive at these emission estimates are summarised in the final column of the table. The values are those for a 100-year time horizon published by the Intergovernmental Panel on Climate Change in 1995. These are the weighting factors agreed for use under the Kyoto protocol during the first commitment period.

² PFCs include mainly perfluoromethane (6500), perfluoroethane (9200), and perfluoropropane (7000). ³ Totals may not correspond exactly to entries in columns due to rounding.

§ Mr. Carmichael
To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the answer of 27 February 2002,Official Report, column 1340W, on greenhouse gas emissions, when the data for 2000–01 will be published. [51978]

§ Mr. Meacher
The process for the collection of data for the years 2000–01 and 2001–02 is under way and we plan to continue previous practice by including this data in the Greening Government Annual Report published in November of each year. Commencing this year we intend to report data on the energy consumption and greenhouse gas emissions of buildings on the Government Estate about 6 months after the end of the financial year, rather than current practice of reporting 18 months in arrears.
