TIGHT, M. ... et al, 2005. What is a sustainable level of CO2 emissions from transport activity in the UK in 2050? Transport Policy 12(3), pp. 235-244.
The paper reports on the development of UK transport targets for CO2 emissions for
2050. Five key studies containing future carbon emissions scenarios for the UK were
used to establish targets for overall reductions in emissions to achieve stabilisation at
550 ppm and 450 ppm of atmospheric CO2. Two approaches were used to consider
the proportion of total emissions that would be attributable to transport in the future:
26% of total emissions as now and an increase to 41% of total emissions in line with
forecasts. The overall targets and expected contributions from transport were used to
derive target emissions for the transport sector to be achieved by 2050, which ranged
from 8.2 MtC to 25.8 MtC. Even the weakest of these targets represents a
considerable reduction from current emissions levels.
