Direct animal emissions for this dairy farm equate to around 86% of the total. The table below shows the impact of the ETS policy over time including the free allocation of NZU's through to 2030. This table includes the estimated emissions and costs from all sectors including fuel, electricity, fertiliser and agriculture. The total cost has been calcualted using an assumed price of carbon of $25.
