Koch Industries, a powerful American energy conglomerate which helped found the Tea Party movement, has now registered to lobby the Alberta government.

Records show the company hired Global Public Affairs, one of the most influential lobby firms in Canada, to represent its interests.

The registration was made on March 15, making Koch Industries legally able to lobby provincial policymakers on the issues of "energy and resource development", "economic development" and "taxation policy."

The privately-owned company, run by Charles and David Koch, is the second largest in the United States. In addition to manufacturing household products like Brawny paper towels, it also refines an estimated 25 percent of all oil sands crude entering America.

The company also owns a crude oil terminal in Hardisty, Alberta, and operates a subsidiary called Flint Hills Resources Canada LP, which it claims to be "among Canada's largest crude oil purchasers, shippers and exporters."

A Koch Industries spokesperson contacted by the Edmonton Journal had little to say about the lobby registration.

"Koch companies want to add value by providing quality services and products our customers desire and value in a way that is compliant with all laws and regulations," reads her one-sentence email reply.

A comprehensive Tyee report earlier this week examined the deep ties between Koch Industries, the Tea Party movement, Wisconsin labour protests, climate change denial and attacks on a cap and trade market for carbon emissions.

This is not the company's first involvement in Canada's political hemisphere.

Between 2005 and 2008, the company provided $175,000 in grants to the Vancouver-based Fraser Institute, a right leaning think tank which has published critiques of climate change science.
