The Liberals have rejected a Conservative motion to study the effect of a carbon tax on agriculture.

Conservative Agriculture Critic David Anderson put forward the motion to the House of Commons Agriculture Committee this week.

Anderson says the refusal to examine the cost of a carbon tax to Canadian farmers and producers is unacceptable.

"We want to know what it's going to cost producers. We know that farmers are already paying for it when they're buying technology - the emissions cost is figured into some of the engines and machinery they're buying.

We know it's going to raise the cost of fuel and food for Canadian consumers. We just want to know what those costs will be," he said.

Anderson says they’ll continue to press the government on this matter.

"If the Liberals are going to move ahead with this, we want them to be transparent and accountable - neither of those things are found in what they're doing.

We will continue to try and hold them to account, but I don't think is going to turn out well for western Canada," he said.

Anderson says the carbon tax failed in the EU and Australia adding it will have a huge impact on agriculture because it impacts every aspect of the industry from fuel to fertilizer and equipment.
