Are "low carbon footprint" measures actually helping?

I think that low carbon footprints help the environment a lot. We can not undo the damage that we have already done to our world, but we can slow it down to a point where things are a lot safer. The industrial revolution didn't cause half as many problems as we do now and we still use that same old technology from back then in many of our factories and manufacturing facilities. We can definitely take steps to help our environment, doubting methods like this is what makes these little problems happen.
