Agricultural emissions research levy
（重定向自Flatulence tax）
The agricultural emissions research levy was a controversial tax proposal in New Zealand. It was first proposed in 2003 and would collect an estimated $8.4 million annually from livestock farmers (out of an estimated annual $50–125 million in costs to the public which is caused by farm animals' emissions of greenhouse gases such as methane), and which would have been used to fund research on the livestock industry's emissions of greenhouse gases, to further the nation's compliance with the Kyoto Protocol.
