Not really. We needed to industrialize to get the point we are now where we can manufacture clean energy. Coal and oil got a humans here from their simplicity (burn it) so that we can now have clean alternatives like solar panels and wind turbines.
So no, cleaning up isn't easier or we wouldn't be fucked right now. By the time we get to Mars as a colony we will, by necessity, have the tech to produce clean energy and will not be able to rely on oil. Thus starting fresh without polluting from the onset - something that was impossible on our own world.
