Waste is any substance or object that has been discarded, that there is an intention to discard, or that is subject to an obligation of disposal. (Ministry for the Ecological Transition and the Demographic Challenge of Spain). Waste can be an important contributor to reducing greenhouse gas emissions and, therefore, in mitigating climate change. The treatment and final disposal of solid waste can result in fewer greenhouse gas emissions. Even better, the prevention and recovery of solid waste can help avoid these emissions in the energy, agriculture, forestry, transportation and industry sectors (Inter-American Development Bank). Adaptation involves the implementation of waste management practices that reduce the vulnerability of communities and countries to the impacts of climate change and foster citizen participation in waste management to scale up resilience (ECLAC).
