“Last year, New Zealand — which has pledged to reach net-zero carbon dioxide emissions by 2050 — proposed a first-in-the-world tax on cow emissions. The levy will depend on factors including the number of animals kept, the size of the farm, the type of fertilizer used and steps farmers take to reduce their emissions. It’s expected to reduce the amount of methane New Zealand’s livestock release into the atmosphere by as much as 47 percent by 2050.” WaPo (Gift Article): How New Zealand plans to tackle climate change: Taxing cow burps. In part because of these burps, agriculture makes up half of the NZ’s emissions.
