Sustainability Concern

Sustainability criteria check for the alignment of scenarios with sustainability targets other than climate-change mitigation. Scenarios are flagged if they report the use of technologies, activities or practices at a level that goes beyond what would be sustainable in those other non-climate ecosystem targets. The thresholds for sustainability criteria are derived from literature focussing on the respective sustainability targets. Misalignment of a scenario does not mean that the scenario is impossible or infeasible, but rather that it is undesirable from a non-climate sustainability perspective.

Possible evaluation outcomes:

• ok — No sustainability concerns
• medium — Moderate sustainability concerns
• high — Strong sustainability concerns
• not assigned — Variable not reported

Criteria:

• Food Availability
• Biodiversity
• Unsustainable Hydropower Use
• Unsustainable Bioenergy Use
• Deforestation
• Exceeding Prudent Limit For Geological Carbon Storage
