APAS has released a carbon tax costing review showing farmers will lose eight percent of their income this year to the new tax.

APAS vice president Ian Boxall says the costing review considers all major farm expenses not exempt from the carbon tax, including grain drying, rail transportation, power, and trucking hauling of crops to market.

He says the stark evidence shows a 5,000 acre grain farm in Saskatchewan will lose eight percent or $8,000 to $10,000 in income to the carbon tax.

In less than two years, when the carbon tax jumps to $50 a ton, he says the farm bill will jump to 12 percent or $13,000 to $17,000 in lost income.

APAS is calling for a carbon tax exemption on all farm expenses, including those from 2019.
