The City of Espoo in Finland is dedicated to achieving carbon neutrality by 2030, focusing on minimizing emissions in construction and maintenance work. They have implemented a strategy to use renewable fuels in their equipment and expect the same from their contracting partners. The city has signed the Green Deal agreement, targeting emission-free worksites by 2025, which involves ending the use of fossil fuels. Espoo aims to reduce carbon dioxide emissions, exhaust emissions, and noise at worksites through principles of emission-free work. To monitor fuel usage, a new testing procedure involving laboratory testing by an independent operator has been introduced, ensuring compliance with agreements. The city is driving for a faster transition to climate-friendly alternative propulsion solutions. Continuous collaboration with partners is key, as exemplified by the upcoming competitive tender to select vehicle and machinery services compliant with the Green Deal agreement. Espoo's Carbon neutral Espoo 2030 roadmap outlines efforts for emission reductions and involves collaboration with residents and partners. The city also participates in the Innovation Challenge Engine for Cities project to develop sustainable urban solutions.
