Decarbonising the transport and energy sectors: Technical feasibility and socioeconomic impacts in Costa Rica

摘要: Abstract Compliance with the Paris Agreement requires transformation of national economies to meet net-zero carbon dioxide emissions by mid-century. To accomplish this, countries need define long-term decarbonisation strategies near- and mid-term actions determine their ideal future scenario while maximizing socioeconomic benefits. This paper describes process followed support creation pathway for transport energy sectors presented in Costa Rica's National Decarbonisation Plan. We discuss detail technological a deep-decarbonisation that supports reaching 2050. Compared business-as-usual (BAU) scenario, our results show can lead emissions' reduction 87% Energy efficiency, adoption electromobility, modal-shift towards public active mobility, as well reduced demand due digitalisation teleworking, are found be key drivers deep-decarbonisation. These measures combined enable 25% primary production The highlight installing 4.4 GW more renewable power plants 2050, compared BAU (80%). also additional investments compensated operating cost. Crucially, we Plan lower total discounted cost about 35% current GDP, indicating deep is technically feasible coupled
