Koch Industries is the biggest leaseholder in Canada’s oil sands, which the Keystone XL pipeline would serve, The Washington Post reported.

Citing data compiled by an activist group that the newspaper confirmed with Alberta provincial records, the Post said a subsidiary of Koch, owned by conservative billionaires Charles and David Koch, holds leases on 1.1 million acres in the oil sands, the largest chunk of the 35 million lease acres.

The findings are surprising because international oil corporations like Exxon Mobil or Royal Dutch Shell are not the largest leaseholders, the Post said.
