Em 2019, as emiss\u00f5es atingiram o n\u00edvel mais alto j\u00e1 visto, de acordo com o \u00faltimo relat\u00f3rio <\/span><\/span><\/span><\/span><\/span><\/span>2020 Global Situation Report for Buildings and Construction<\/span><\/span><\/span><\/span><\/span><\/span><\/a><\/p>

Por\u00e9m, em 2020 com a pandemia, houve muitas paralisa\u00e7\u00f5es que ajudar\u00e3o na redu\u00e7\u00e3o que ser\u00e1 contabilizada no pr\u00f3ximo relat\u00f3rio anual. Surgir\u00e3o oportunidades para aumentar a renova\u00e7\u00e3o dos edif\u00edcios e os padr\u00f5es de desempenho dos edif\u00edcios rec\u00e9m-constru\u00eddos, ajudando tamb\u00e9m a reduzir as emiss\u00f5es e a promover a sustentabilidade do sector. Os governos d\u00e3o prioridade ao est\u00edmulo p\u00f3s-Covid-19 para edif\u00edcios de baixo carbono. <\/span><\/span><\/span><\/span><\/span><\/span>
50% das emiss\u00f5es diretas e 60% das emiss\u00f5es indiretas devem ser reduzidas at\u00e9 2030, para alcan\u00e7ar a neutralidade clim\u00e1tica proposta pelo Tratado de Paris (COP 21) at\u00e9 2050. Esta redu\u00e7\u00e3o equivale a 6% at\u00e9 2030. <\/span><\/span><\/span><\/span><\/span><\/span>\u00b9<\/span><\/span><\/span><\/span><\/span><\/span><\/a><\/span><\/p>

Nenhum Brasil emite 2,17 GtCO2 em 2019. Isto \u00e9 9,6% superior ao de 2018, segundo o estudo realizado pelo observat\u00f3rio do clima, Sistema de Estimativa de Emiss\u00f5es de G\u00e1s de Fog\u00e3o (SEEG) <\/span><\/span><\/span><\/span><\/span><\/span>5<\/span><\/span><\/span><\/span><\/span><\/span><\/a> . De acordo com esse resultado, o Brasil ocupa a sexta posi\u00e7\u00e3o no ranking dos dois pa\u00edses mais polu\u00eddos pela atmosfera. <\/span><\/span><\/span><\/span><\/span><\/span>\u00b3<\/span><\/span><\/span><\/span><\/span><\/span><\/a><\/span><\/p>

O setor de processos industriais de materiais para constru\u00e7\u00e3o civil foi respons\u00e1vel por 99,1 MtCO2e. Equivalente a 5% das emiss\u00f5es brutas nacionais. H\u00e1 uma queda de 2% em rela\u00e7\u00e3o ao ano anterior. As principais fontes de emiss\u00e3o s\u00e3o para a produ\u00e7\u00e3o do setor de cimento, ferro-gusa e a\u00e7o.<\/span> <\/span><\/span><\/span><\/span><\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
