Agriculture (particularly the beef and dairy sub-sector) and transport are two intensive producers of carbon emissions. 

Arla has been implementing a scheme which promises to reduce the carbon emissions of both arms of its operation: first by capturing the methane in the slurry produced by its cows, and second by using that methane to power its trucks. 

Double-counting? Perhaps... but the benefits are clear, especially when it is remembered that methane is a much more potent greenhouse gas compared to carbon dioxide (in the region of 23 times more potent).
