The Country-Level GDP and Downscaled Projections Based on the Special Report on Emissions Scenarios (SRES) A1, A2, B1, and B2 marker scenarios, 1990-2100, were developed using the 1990 base year GDP (Gross Domestic Product) from national accounts database available from the UN Statistics Division. The scenarios developed by the IPCC in the Special Report on Emissions Scenarios (SRES) are a result of four different storylines, titled A1, A2, B1, and B2. Each storyline assumes a distinctly different direction for future developments of driving forces.

These four families are known as ‘A1’, ‘A2’, ‘B1’ and ‘B2’. Some IPCC studies have been able to foresee four possible future scenarios (A1, A2, B1, B2), by taking into consideration population growth, economic development, available resources (meaning primary energy sources) and technology.

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. The SRES scenarios are divided into four families, or storylines, that describe distinctly different future developments of economic growth, global population and technological change. These four families are known as ‘A1’, ‘A2’, ‘B1’ and ‘B2’.

The numerical simulations are carried out for all four illustrative “marker” scenarios of A1, A2, B1, and B2. The B1 and B2 scenarios assumed more sustainable practices ('utopia'), with more global-focus and regional-focus, respectively. Let us now directly compare the various SRES scenarios both in terms of their annual rates of carbon emissions, measured in gigatons (Gt) of carbon (1Gt = 10 12 tons), and the resulting trajectories of atmospheric CO 2 concentrations.

Some IPCC studies have been able to foresee four possible future scenarios (A1, A2, B1, B2), by taking into consideration population growth, economic development, available resources (meaning primary energy sources) and technology. These hypothetical evolutions are called “scenario families”. 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). For A1 and B1 scenarios, regional population trajectories are (almost for all years) within the proposed 5% interval of their respective marker scenarios, except for two of the scenarios 18. 4.4.3.2.
