Links between circular economy and climate change mitigation in the built environment

摘要: Abstract The construction sector represents one of the most significant sources waste generation in European Union (EU), with nearly billion tonnes and demolition annually. This also contributes a third annual EU greenhouse gas (GHG) emissions. Accordingly, priority area for intervention within Action Plan Circular Economy. Increasing resource efficiency through slowing, closing, narrowing material energy loops, is key to mitigating climate change. However, this review paper demonstrates that analysis links between circular economy solutions change mitigation has been scarce, despite recent sharp increase related literature, 20 articles (83%) published 2018–2019. Slowing have focus research could bring up 99% savings GHG emissions per functional unit, where reuse stands out as promising alternative. Closing can reduce by 30–50% but results are highly dependent on recycling efficiencies transportation distances recovery facilities. Solutions loops additional savings, they remain understudied. Despite emissions, article argues do not always result default emission reductions case-by-case quantification crucial. implementation these should be accompanied further methodological development, such proper allocation procedures, accurate definition system boundaries integration forecasts.
