Study finds emissions from road construction could be halved using today’s technology

Green Car Congress

The construction sector accounts for a quarter of CO 2 emissions, in Sweden and globally. All the materials and activities involved in its construction were calculated for their total climate impact: energy and materials used in the construction and what emissions these contribute to.

Study finds there is still room for optimization of particle emissions based on diesel fuel properties

Green Car Congress

Researchers in Europe have found that while diesel particulate filters (DPFs) have to a large extent masked the role of diesel fuel properties on particulate emissions, there is still room for optimization, especially in particle number (PN) emissions of vehicles with frequent regenerations. n market Euro 6 vehicles is available.
