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
In-Person Market Dialogue in Oslo
01 December 2021
On 1 December, the working group participants came together in person for the first time to exchange and meet the market to explore the potential for innovative solutions in the field of zero-emission contruction sites. Read about the event here.

New pedestrian street brings new life to Oslo city centre
“We are particularly proud of two achievements with Olav Vs gate. One is that we have developed a new pedestrian street in the centre of Oslo. The other is that we have achieved this almost without emissions,” explains Karin Dalberg, Project Manager at the Agency for Urban Environment.
The City of Oslo has a clearly defined climate strategy which states that by 2030, greenhouse gas emissions shall be down by 95 percent compared to 2009 levels. To achieve this goal, there are specific targets for emission reduction. By 2025, all construction sites on behalf of the municipality shall be emission-free. The upgrade in Olav Vs gate has been a pilot project for zero emission site operation, and is an important step towards the transition which must come to the contruction industry.
Many new electric excavators expected next year
Next year, probably 15 percent of new excavators in Norway will be electric. Behind it are brave players who drive development forward. During an in-person market dialogue in Oslo, Big Buyers participants met various market actors to discuss innovative solutions to tackle emissions from construction works.

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
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
