New Zealand is planning to introduce a world-first tax on methane and nitrous oxide emissions from agricultural activities, primarily from the six million cows and 26 million sheep. The tax is designed to mitigate the environmental impact of agriculture, which contributes to around 30% of global warming since the Industrial Revolution. Initially, farmers were to be taxed based on their animals' emissions, leading to protests. The government has since revised the plan, allowing farmers to offset emissions through forestry development, with the prime minister emphasizing the goal of reducing emissions while maintaining international competitiveness. The New Zealand Farmers' Federation has criticized the government for the proposed tax and its lack of clarity, arguing that agriculture is an efficient and sustainable sector.
