Demand-side mitigation and new ways of providing services can help avoid, shift, and improve final service demand. Rapid and deep changes in demand make it easier for every sector to reduce greenhouse gas (GHG) emissions in the short and medium term (high confidence). {5.2, 5.3}The indicative potential of demand-side strategies to reduce emissions of direct and indirect CO 2 and non-CO 2 GHG emissions in three end-use sectors (buildings, land transport, and food) is 40-70% globally by 2050 (high confidence). Technical mitigation potentials compared to the 2050 emissions projection of two scenarios consistent with policies announced by national governments until 2020 amount to 6.8 GtCO 2 for building use and construction, 4.6 GtCO 2 for land transport and 8.0 GtCO 2 -eq for food demand, and amount to 4.4 GtCO 2 for industry. Mitigation strategies can be classified as Avoid-Shift-Improve (ASI) options, that reflect opportunities for socio-cultural, infrastructural, and technological change. The greatest 'Avoid' potential comes from reducing long-haul aviation and providing short-distance low-carbon urban infrastructures. The greatest 'Shift' potential would come from switching to plant-based diets. The greatest 'Improve' potential comes from within the building sector, and in particular increased use of energy-efficient end-use technologies and passive housing. {5.
