Understanding Changes in UK CO2 emissions 1992-2004: A structural decomposition approach

The report finds that while UK producer emissions remained relatively stable due to the 'dash for gas' and a transition to a service economy, consumer emissions increased significantly. This growth was primarily driven by rising final consumption levels, which outpaced technological efficiency gains. The analysis highlights that the UK's shift toward services shifted carbon-intensive production to other regions, particularly non-OECD countries, and that services are a major driver of indirect emissions through their global supply chains.

• Between 1992 and 2004, total sectoral producer CO2 emissions in the UK increased by 3.5 Mt CO2, but this was largely offset by cumulative reductions from fuel mix changes (42 Mt), fuel efficiency improvements (63 Mt), and production structure changes (60 Mt).
• The primary driver of emission increases for both producer and consumer accounts was the growth in final consumption levels. For producer emissions, this caused cumulative growth of 203 Mt CO2, while for consumer emissions, it added 248 Mt globally.
• The 'dash for gas' in the early 1990s, following the privatisation of the electricity sector, significantly reduced producer emissions by switching from coal and fuel oil to natural gas.
• The UK's transition toward a service-based economy reduced direct producer emissions, but this was largely a result of the international division of labour, shifting carbon-intensive production to other regions.
• UK consumer emissions increased by 69 Mt CO2 between 1992 and 2004, with the most rapid growth occurring in emissions from production in non-OECD regions, which grew by 54 Mt.
• When indirect emissions from the global supply chain are included, the service sector becomes the largest individual contributor to changes in UK sectoral consumer CO2 emissions, adding 30 Mt since 1992.
• In the transport sector, direct CO2 emissions increased by 32 Mt between 1992 and 2004, driven by growing final demand and a specific increase in fuel intensity within the air transport industry.
• Direct household CO2 emissions from housing increased by 2.4 Mt between 1992 and 2004, influenced by rising internal home temperatures (from 15.5° to 18.0°) and population growth, despite reductions from a shift toward gas.
