Stephen Cadogan: Across Europe, countries are grappling with ways to cut farming emissions

Denmark is a major pork and dairy exporter. Its agriculture emissions make up 22.4% of the country's total carbon emissions.
A carbon tax that could cut Danish agricultural production as much as 15%, and UK farmers getting up to €1,252 per hectare for environmental land management, have re-ignited a debate about producing food versus looking after the environment.
An expert group commissioned by the Danish government proposed a farming tax of up to €101 per tonne of greenhouse gas emissions. It would reduce agricultural production by between 6% and 15%, with cattle and pig production falling by about 20% if the harshest taxation rate proposed was adopted.
