- * B1, A1B, and A1FI are three greenhouse gas emission scenarios defined by the IPCC
Special Report on Emissions Scenarios (SRES), where B1 is a relatively low emissions
scenario (often considered to be a "best case"), A1B is a moderate emissions scenario,
and A1FI is a fossil-fuel intensive emissions scenario (often thought of as a "worst
case"). Recent observations of emissions make the A1FI the most plausible compared to
other scenarios, thus making this the "business as usual" case.
