Machine manufacturers and construction companies around the globe are currently searching for ways to achieve the goal of climate-neutral construction. The challenge here is to successively reduce emissions of CO2 and other harmful gases (summarized to CO2 equivalents: CO2e) around the world to zero over the coming decades. In the road construction sector, this transformation is inextricably linked to the improvement and further development of production and working processes. In the future, machines and construction materials will also be assessed based on the climate-harmful emissions arising from their production and use. However, the focus should not be on individual machines, but on the entire process leading up to the finished product – a road. Ultimately, the decisive factor is the emissions generated per kilometer of newly built or rehabilitated road – the “CO2e per work done”.

The shift toward a circular economy approach is key to the transition towards net zero carbon emissions. At Volvo Construction Equipment (Volvo CE), keeping construction machines – and their parts – in action for longer, to maximise their useful life, is a core part of its sustainability ambitions.
