Zero-Emission Construction Sites (ZECS) are worksites where only zero-emission construction machinery and transport operate. The construction stage is among the most emission-intensive phases in the life cycle of buildings and infrastructure, and decarbonising it reduces their embodied carbon. 

Cities account for a large share of global greenhouse gas emissions, and they also have the means to reduce them. The experience of Barcelona, Utrecht and Stockholm shows that green public procurement is one of the most powerful instruments cities can use to meet their climate goals, protect workers’ and citizens’ health and create lead markets for clean construction.
