Medium-high emissions are attained in most of the A1 group scenarios (including the A1B marker, A1B-AIM), but also in scenarios from the B2 scenario family with high fossil-fuel use (e.g., B2-ASF).

FN har opstillet fire hovedscenarier er A1, A2, B1 og B2, der tilsammen giver et billede af de mulige udviklingsforløb. Ingen af FN's scenarier forudsætter implementering af FN's klimakonvention, herunder Kyotoprotokollen, eller yderligere klimapolitiske tiltag.

Instead, a scenario is a possible future based on a given set of assumptions based on energy use, emissions, land use and general climate system behavior. The IPCC Special Report on Emissions Scenarios (SRES) describes four families of scenarios: A1, A2, B1 and B2 (Fig. 1) (Nakicenovic et al., 2000). The A1 storyline and scenario family describes a future world of very rapid was chosen for each of the six scenario groups A1B, A1FI, A1T, A2, B1 and B2. 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  SRES Reference Scenarios. IPCC sponsored 40 emissions scenarios for GHGs, sulfur dioxide, and other gases — A1, A2, B1, B2; The scenarios are published  1999 IPCC Special Report on Emission Scenarios (SRES). 2001 IPCC AR3 uses IS92 A1.

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. scenarios – Leggett et al., 1992).
