Economic mitigation potentials by sector in 2030 estimated from bottom-up studies
Figure SPM.10. Estimated economic mitigation potential by se ctor in 2030 from bo ttom-up s tudies, c ompared to the respective baselines
assumed in the sector assessments. The potentials do not include non-technical options such as lifestyle changes. {Figure 4.2}
a) The ranges for global economic potentials as assessed in each sector are shown by vertical lines. The ranges are based on end-use allocations of
emissions, meaning that emissions of electricity use are counted towards the end-use sectors and not to the energy supply sector.
b) The estimated potentials have bee n constrained by the availability of studies particular ly at high carbon price levels.
c) Sectors used different baselines. For industr y, the SRES B2 baseline was taken, for energy sup ply and transport, the World Energy Outlook
(WEO) 2004 baseline wa s used; the building sector is base d on a baseline in between SRES B2 and A1B; for waste, SRES A1B dr iving
forces were used to con struct a waste-specific baseline; agriculture and forestry used baselines th at mostly used B2 driving forces.
d) Only global totals for transport are shown because inter national aviation is included.
e) Categories excluded are: non-CO2 emissi ons in buildings and transport, part of material efficiency options, heat production and co-gener a-
tion in energy supply, heavy duty vehicles, shipping and high-occupancy passenger transpor t, most high-cost options for buildings, wastewa-
ter treatment, emission reduction from coal mines and gas pipelines, and fluori nated gases from energy supply and transpor t. The underes-
timation of the total economic potential from these emissions is o f the order of 10 to 15%.
