SRES limits the possible scenario outcomes by establishing four broad scenario families (A1, A2, B1, B2), which correspond to possible future world situations. These scenarios each come with a corresponding narrative storyline to describe global social, economic, technological, environmental, and …
Oct 5, 2013 experts were involved in different combinations (Table A1 in the Appendix). global SRES scenario families (i.e. A1B, A2, B1, B2), the.

IPCC Substantial economic potential for the mitigation of global GHG emissions over the coming decades • Both bottom-up and top-down studies The IPCC Special Report on Emissions Scenarios (SRES) developed 40 plausible futures based on various assumptions about demographic change, economic development and technological change (IPCC, 2000). These were grouped into four ‘storylines’ (A1, A2, B1 and B2). A1. The A1 storyline describes a … Four scenario “storylines” were developed and labeled, for simplicity, A1, A2, B1, B2. These storylines were the result of analyzing different viewpoints on possible future development pathways by the members of the writing team. They have been discussed at length elsewhere (Parry, 2000, Nakićenović et al, 2000) and will be described only in The B2 storyline and scenario family describes a world in which the emphasis is on local solutions to economic, social and environmental sustainability.

2012-05-23 · Six groups of scenarios were drawn from the four families: one group each in the A2, B1 and B2 families, and three groups in the A1 family, characterising alternative developments of energy technologies: A1FI (fossil intensive), A1T( predominantly non-fossil) and A1B (balanced across energy sources).

Figure 5-7: Standardized global N 2 O emissions for SRES scenarios, classified into four scenario families (each denoted by a different color code - A1, red; A2, brown; B1, green; B2, blue). Marker scenarios are shown with thick lines without ticks, globally harmonized scenarios with thin lines, and non-harmonized scenarios with thin, dotted lines (see Table 4-3 ). A2 and B2 were the main scenarios used in the IPCC Third Assesment Report (TAR, 2001) and later A1B has been the most common scenario.

Emission Scenarios (Nakićenović, 2000). SRES-scenarier kan betraktas som ”familjer” med huvudsakliga beteckningarna A1, A2, B1 och B2.
The IPCC scenarios are based on a data-driven storyline (or narrative) of what events have occurred in the past and how the future may unfold. There are four commonly used scenario families. They are labeled A1, A2, B1, and B2. Referred to by letter-number combinations such as A1, A2, B1, and B2, each scenario was based on a complex relationship between the socioeconomic forces driving greenhouse gas and aerosol emissions and the levels to which those emissions would climb during the 21st century.
