If an entity is doing something 'bad', reducing the scope or amount of that behavior is neither hypocritical nor pointless. It doesn't matter if it's a big company that pollutes, or an individual trying to reduce a bad habit. Movement in the right direction is an essential part of things getting better.
I disagree that it can't be hypocritical. If Norway was doing this for environmental reasons I think it'd be quite hypocritical. That doesn't mean it's not a good thing to do though.
