Abstract
AbstractThis study adapts a climate change mitigation model to assess impacts of municipal solid wastes in the Middle East and North Africa region, taking into account the future development of integrated waste management infrastructure involving collection, treatment and disposal. Mitigated and unmitigated disposal scenarios including waste growth reduction are used to estimate disposal methane emission changes at regional and subregional level. This study shows that unmitigated regional emissions by 2050 could rise to 296 542 GgCO2eq from a current level in 2015 of 128 184 GgCO2eq additionally decreasing annually by up to 8.75% falling to 10.16% due to waste characterisation changes as developing countries in the region progress to developed country status. A further annual rise, due to hotter drier climate conditions experienced as desertification, of up to a range of 1.70% increasing to 2.29% is also demonstrated. The findings enable regional planners to better assess and develop plans for implementation of integrated waste management policies.
