Mr. Battle

To ask the Secretary of State for the Environment what is his estimate of the type and amount of toxic emissions(a) per mile, (b) per minute of transmission, and (c) per head of number of passengers per mile or per minute of (i) a family sized car, (ii) a diesel-electric train, (iii) a double decker bus, (iv) a milk float and (v) a bicycle.

Mr. Heathcoat-Amory

I shall write to the hon. Gentleman.

Dr. Kim Howells

To ask the Secretary of State for the Environment what proportion of carbon dioxide emissions into the atmosphere in the United Kingdom have been accounted for(a) by electricity generation, and (b) by petrol and diesel-driven road vehicles in 1987, 1988 and 1989.

Mr. Heathcoat-Amory

Percentages of carbon dioxide emissions from selected sources in 1987 were as follows:

1987
Power stations 34.0
Petrol driven road vehicles 12.0
Diesel driven road vehicles 5.0

In 1987 a little more than one third of carbon dioxide emissions in the United Kingdom came from power stations. Approximately 12 per cent. came from motor spirit and a further 5 per cent. from DERV. Figures for 1988 are currently being prepared and will be published in the Digest of Environmental Protection and Water Statistics early next year. Figures for 1989 are not yet available.

Mr. Heathcoat-Amory

Percentage of sulphur dioxide emissions from selected sources was as follows:

1987

In 1987 almost three-quarters of sulphur dioxide emissions in the United Kingdom came from power stations. Only a little more than 1 per cent. came from motor spirit and from DERV. Figures for 1988 are currently being prepared and will be published in the Digest of Environmental Protection and Water Statistics early next year. Figures for 1989 are not yet available.
