Zero-emission construction sites

Building and infrastructure construction works conventionally use diesel-fuelled heavy machinery (NRMM). To achieve climate neutrality by reducing carbon emissions - as well as to reap benefits of reduced local air pollution (NOx, SOx, PM), less noise and nuisance - public buyers are demanding emission-free construction machinery on municipal building and infrastructure sites. Though small electric machines are more and more common, large emission-free NRMM like excavators are still scarce. The working group will exchange on pilots and jointly aggregate demand to accelerate the transition to zero-emission construction sites.

Focus of the Working Group

  • Low-/ Zero-emission construction sites

  • Use of emission-free construction machinery for public works

Collaborative Market Dialogue Preparations

 18 June 2021

Presentation by Helsinki

Case Study, City of Helsinki

After updates from two working group participants (City of Helsinki & City of Copenhagen) on their current progress and challenges, the group collaborativly prepared for the upcoming joint market dialogues which will start in September.

Kick off Meeting

  12 April 2021

Introductory Presentation by Kaitlyn Dietz, ICLEI

The Participants got together to meet for the first time, exchange on common needs and to prioritize the work within the group.


Objectives of the working group

  • Exchange experiences  and best practice (policy/ strategy and practical implementation)

  • Share market intelligence and engage in joint market dialogues

  • Jointly develop and implement procurement approaches (procedure, minimum requirements, award criteria) for low- and zero-emission public construction sites

  • Exchange ideas on contract performance and emissions monitoring during construction (what data to collect, how, when - establishing baseline and calculating emissions reduction)

  • Explore and strengthen solutions for reliable on-site energy supply

  • Develop and communicate  ZEMCONS value-added for others (market and agency level - e.g. what industrial transition/ transformation is taking place, why suppliers should join the transition)

  • Scale-up zero-emission construction sites from pilots to standard practice, by mainstreaming of emission-free with wider institutional and industry green transition

Added Value

  • Aligned demands for a transition to zero-emission construction across public buyers, to accelerate industry innovation

  • Proven feasibility and documented socio-environmental and economic impact of zero-emission construction machinery and sites

  • Increased visibility of the importance of construction site emissions, and of the potential actions available to buyers to address them
