With the best technologies and practices available today, it is technically possible to halve CO2 emissions from road construction, as well as reduce them by more than three quarters by 2030 and achieve close to net zero emissions by 2045.
The paper – “Reaching net-zero carbon emissions in construction supply chains – Analysis of a Swedish road construction project” – assesses the potential for reducing the climate impact of road construction. The proposed solutions include increased recycling of steel, asphalt and aggregates; enhanced use of alternative binders in concrete; use of sustainably produced second-generation biofuels; and other policy measures and procurement strategies.
