If you point your finger at the energy consumed by teams to keep ice in their buildings 10 months of the year, then maybe you're onto something. Power generation, heating and inefficient ground transportation is and always will be the main culprits of global emissions until a totally renewable and highly implemented power source is adopted globally. This proposal seems like nothing more than uneducated drivel to me which is sad coming from the Globe and Mail. As it stands now, air travel makes up an estimated 1% of C02 emissions as a whole, with the majority of that obviously not coming from the NHL, but general travel and shipping.
I would wager the annual Flames power consumption at the dome far exceeds their air travel carbon footprint each and every year. If this is the stance people want to take, you might as well get rid of ice and ask the players to start playing roller hockey.
