There have been reductions in the level of greenhouse gas
emissions across most sectors between 1995 and 2009 but one of
the key drivers of the 42.0 per cent decrease in emissions
intensity has been the switch away from coal to natural gas for
electricity generation. The electricity, gas and water supply
industries produced 5,200 tonnes of emissions (CO2 equivalent)
per million pounds of economic output in 2009, less than half
that produced in 1995 (11,400 tonnes). There has been an
increase in the emissions intensity for the agriculture,
forestry and fishing industry. Emissions of greenhouse gases
have fallen in this sector by 17.7 per cent between 1995 and
2009 but output (gross value added) was down 32.6 per cent over
the same period. Source: Office for National Statistics
Comparisons are made with 1995 for the industry analyses of
greenhouse gas emissions intensity as this is the earliest year
for which economic output (GVA) data is available on an SIC07
basis at the industry level. Details of the policy
