Estonians Tax Cow Farts

I wasn't expecting to write a headline like that when I got up this morning, but there you go. The Estonians are taxing cow farts. From RIA Novosti:

Estonian farmers have received tax notices for methane emissions from their cattle, the country's opposition party, the People's Union of Estonia, said on Thursday.

Ruminants produce large quantities of methane gas through belching and flatulence when they digest grass, which accounts for about 15-25% of overall gas emissions, according to different estimates.

A single cow produces on average 350 liters of methane and 1,500 liters of carbon dioxide per day.
