That'll save their bacon.

From The Daily Mail:

Denmark is considering a tax on red meat over fears cattle flatulence was causing climate change.

A government think tank said consumers were 'ethically obliged' to change their eating habits in a bid to cut greenhouse gas emissions.

The Danish Council of Ethics said cattle accounted for around 10 per cent of the CO2 released into the atmosphere, while food production makes up around another 20 per cent.

Ho hum, the article only mentions cattle and not pigs.

As we well know (having quickly Googled it), Danish pig farmers export nearly half their output, with a value of DKK 30 billion a year (about £3 billion), so this will knock back domestic demand for "red meat" (presumably more likely to be imported) and hence boost domestic demand for pork and bacon.

Win-win for Danish pig farmers!
