Recycled concrete and low-carbon cement


In the city of Zurich, the use of recycled concrete and low-carbon cement in new public buildings is commonplace today. Zurich’s public procurement policy, together with initial technology support, created a market for recycled concrete over time, successfully expanding into the private market.

For the past 20 years, Zurich has championed the use of recycled concrete in buildings to preserve nature and reduce local urban waste. By requiring a minimum share of recycled aggregates in concrete for new buildings, Zurich’s public procurement policy created a market for recycled concrete in construction. As more suppliers moved into recycled-concrete production, and users’ confidence in the product grew, the market expanded into the private sector. Next, the city of Zurich explored options to reduce greenhouse gas emissions in construction and required the use of low-carbon cement, in addition to recycled concrete, for new public buildings.

    Breaking free from fossil gas: a new path to a climate-neutral Europe

    An accelerated phase-out of fossil gas can strengthen Europe’s energy security and help reduce emissions faster, by up to 60% by 2030. Through structural demand reductions, the EU can halve the use of fossil gas this decade and phase it out of energy systems by 2050 while maintaining industrial production and ensuring security of supply, Agora’s EU Gas Exit Pathway shows.

    Reducing embodied carbon in construction materials: RE2020 in France

    In France, up to 90% of a new building’s greenhouse gas emissions are generated during the construction and demolition phases. A new regulation, called RE2020, sets a cap on those emissions. With a phase-in period followed by tighter caps over time, the French government aims to trigger a progressive transformation of the whole construction value chain towards the production and use of low-carbon building materials.
