The IPCC SRES emissions scenarios (A1, A2, B1, B2) used population projections from both the United Nations (UN) and the International Institute for Applied Systems Analysis (IIASA). A2, B1, and B2, plus three groups within the A1 scenario family, A1B, A1FI, and A1T – and four cumulati ve emissions categories were developed as the smallest subsets of SRES Panel on Climate Change (IPCC) were done to investigate the direct and indirect climate impacts of the anthropogenic sulfate and carbonaceous aerosols in the future projections of climate change.

The A1 and B1 scenarios all shared a common, relatively low, population projection from IIASA, while the A2 scenario used a relatively high population projection from IIASA (Lutz et al., 1996).

Less rapid and more fragmented technological change These four families are known as ‘A1’, ‘A2’, ‘B1’ and ‘B2’. The A1 family is further subdivided into three groups (A1FI, A1T and A1B), so there are in total six scenario groups, for which so-called ‘illustrative’ emissions scenarios were developed by IPCC Working Group III in 2000. They are grouped by shaded areas for the scenario families A1B, A2, B1, and B2 with respective markers shown as lines. In addition, the four scenario groups within the A1 family A1B, A1C, A1G, and A1T, which explore different technological developments in the energy systems, are shaded individually.

The A1 and B1 scenarios all shared a common, relatively low, population projection from IIASA, while the A2 scenario used a relatively high population projection from IIASA (Lutz et al., 1996). These two projections spanned, at the global level, approximately the 90% uncertainty interval associated with the IIASA probabilistic projections (i.e. a level just within the 5th and 95th percentiles

The six families of scenarios discussed in the IPCC's Third Assessment Report (TAR) and Fourth Assessment Report (AR4) are A1FI, A1B, A1T, A2, B1, and B2. The IPCC did not state that any of the SRES scenarios were more likely to occur than others, therefore none of the SRES scenarios represent a "best guess" of future emissions.

Each storyline produces one of the four “scenario families” (A1, A2, B1, and B2), under which exist six “scenario groups” (three in A1: A1FI, A1T, A1B, and one in each of the other three families, and under the groups reside the 40 GHG emissions scenarios.
