Integrated Assessment Consider 3 crucial aspects of sustainable climate protection measures: • Mitigation • Adaptation • Development
Action Field Check Identify • Ecological Assets • Economic Sectors • Social Systems highly sensitive to subset / totality of aspects Prioritize accordingly!

LLL Examples • Urbanization of coastal zones, mountain ranges, arid regions • „Stradification“ of natural habitats • Expansion of single-purpose fossil-fuel-based power stations WWW Examples • Reduction of black carbon emissions through biomethane generated from degraded-land afforestation • Solarthermal power generation + desalinization by energy towers • Sustainable architecture
