n addition to the dump trucks, electric wheel loaders and an electric grader have been put into operation on the project. The grader is the first of its kind in the world. The project management is continuously working to introduce new electric machines to replace fossil-fueled machines.
"Fuel represents a large part of our greenhouse gas emissions, and much of the fuel consumption is related to earthmoving. Therefore, it's especially important that these machines are electrified," says Nora Omdal Schjoldager, climate and environment manager at AF Anlegg.
"At the same time, we must consider a cost-benefit mindset, especially when it comes to reducing greenhouse gas emissions. For large machines, electrification is expensive and the waiting time is long, so it's important that we don't overlook other measures that could provide greater greenhouse gas reductions per dollar. As for personal vehicles, many projects have already electrified, and the replacement here is happening quickly."
Electrifying the machinery fleet is just one of many measures to reduce greenhouse gas emissions in construction projects. Reduced resource usage, low-carbon concrete, and changes in constructions can both lower emissions and minimize environmental impact. In the E6 Roterud-Storhove project in Innlandet, a new bridge concept was developed during the collaboration phase, saving the environment from emitting 20,000 tons of CO2 equivalents.
"Our industry contributes to significant greenhouse gas emissions, but that's precisely what is motivating. When the volumes are so large, even small changes result in significant reductions. We are starting to have better figures on our greenhouse gas emissions, both direct and indirect, and, together with the rest of AF Gruppen, we aim to halve greenhouse gas emissions in our projects by 2030," says Nora Omdal Schjoldager.
