IPCC IS92 Global Greenhouse Gas Emissions Scenarios 1990-2100

Six global and regional greenhouse gas emissions scenarios (IS92 A-F) project potential futures from 1990 through 2100. These scenarios, published in the 1992 IPCC Supplementary Report, model emissions evolution under varied socio-economic assumptions without new climate policies. The definitive digital version was edited in 2005 by Columbia University's CIESIN to resolve historical data discrepancies.

Use Cases

• Comparing emissions trajectories across six distinct socio-economic and technological assumption sets (Scenarios A-F).
• Analyzing regional contributions to global greenhouse gas emissions over a 110-year period.
• Using the 1990-2100 time-series data as input for climate impact or integrated assessment models.
• Studying the historical development of IPCC scenario methodology preceding later SRES and RCP frameworks.

Strengths

• Provides a 110-year projection window (1990-2100) for long-term trend analysis.
• Represents a definitive, edited version from 2005 that resolved inconsistencies in earlier digital releases.
• Contains six distinct scenarios offering a wide array of assumptions about future socio-economic development.

Limitations

• Specific column names, row counts, and file sizes are not documented on the available platforms.
• Conflicting 'last updated' dates exist between sources (2100-12-31 on NASA EarthData and 2026-03-13 on Data.gov).
• Scenarios are from 1992 and have been superseded by newer frameworks like SRES and RCP/SSP for contemporary research.
