43: Cow farts can be taxing. Denmark plans to tax farmers for the greenhouse gases emitted by their cows, sheep, and pigs from 2030. The taxes – a world first – aim to reduce Danish greenhouse gas emissions by 70% by targeting a major source of methane emissions. The tax will start at $17 per ton of carbon dioxide equivalent in 2030 and increase to $43 per ton by 2035.
