Environmentally adjusted productivity growth and shadow prices for dairy farms
Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Integrated routing of heavy electrical and diesel trucks in forest transports
International Transactions in Operational Research, EarlyView.Abstract Fossil‐free forestry transports are important to reach climate goals. In Sweden, road transports account for around 50% of the industry's CO2 emissions and almost 20% of the road freight volumes. Previous studies have shown that electrification is a cost‐effective way for carbon abatement, while at the same time the requirements for ...
