Carbon dioxide, Methane and Nitrous Oxide are all modelled in TIAM-UCL and these are linked to each individual technology.
TIAM includes energy related CO2, land-use (and forestry) CO2, and non-CO2 gases CH4 and N2O. CH4 from upstream, landfills, manure, rice paddies, enteric fermentation, wastewater is based on EMF-22 data and WEO-2008. N2O from industry and agriculture is based on WEO-2008. CO2 from land-use is based on the Reference scenario of the United States Climate Change Science Program (MIT) presented in Prinn et al. (2008). UK data for Non-CO2 gases are taken from UK greenhouse gas inventory national system (www.ghgi.org.uk).
Some other greenhouse gases (CFCs, HFCs, SF6, etc.) and chemically active gases such as NOX, CO, VOCs are not explicitly modelled, but their radiative forcing is represented as an exogenous extra term in the Forcing expression (this is only for climate module). When aggregate non-CO2 emissions (CH4 and N2O) to CO2 equivalent, the model uses a factor of 0.025 for CH4 and 0.298 for N2O.
The emissions accounting for non-CO2 emission sources are listed in Table 5.1 below. These emission sources are important to include when running climate targets taking account of all GHGs. Emission levels are exogenously determined using EMF data.
