When asked by Global News' Marieke Walsh about what the premier has pitched to the feds as a carbon pricing alternative, Stephen McNeil went on the attack.

Nova Scotia isn't welcoming the prime minister's sudden announcement that Ottawa will set and enforce, if necessary, a minimum price for carbon production.

The federal government is preparing to announce a national policy for carbon pricing this fall and Environment Minister Catherine McKenna has indicated there will be a specific definition of what meets that standard.
