Emissions scenarios

Scenarios have been developed describing alternative pathways of greenhouse gas emissions up to 2100, which depend on assumptions about future global socio-economic and demographic developments. Six different emissions scenarios are presented, taken from the IPCC Special Report on Emissions Scenarios (SRES).

The Special Report on Emissions Scenarios (SRES) describes possible future developments of the world grouped in scenario families that each follow a storyline. Each storyline assumes a distinctly different direction for future developments, such that the four storylines differ in increasingly irreversible ways.

The four scenario families, named “A1”, “A2”, “B1” and “B2”, cover a wide range of key “future” characteristics such as demographic change, economic development, and technological change. Each storyline is quantified in a number of different scenarios (40 in total. Six of these are highlighted by the SRES report to illustrate alternative conditions, three for the A1 storyline and one each for the other storylines. The scenarios were used as input data for the FINSKEN scenarios.

The storylines can be described briefly as follows:
