Carbon Footprint?

O.K. I know about carbon footprint and I agree that we need to reduce our carbon footprint. BUT.. What about "Albedo Footprint"? I mean each of us owns "things" that are more or less reflective of incomming sunlight: white cars versus black cars, houses paited white or some light color versus houses painted dark/sunlight absorbing color, etc.. And what about roads and parking lots: couldn't some additive to the asphalt/concrete make these surface structures more relective of sunlight and therefore less "releasing" of infrared radiation to which the CO2 laden atmosphere is opaque? Polar ice-caps and glaciers (which are highly reflective of incomming solar light) are going or gone. What if we replaced our own objects with higher-albedo- surfaced objects? I'm just wondering what would happen. The auto fleet is replaced in just a few years and houses need repainting every few years. What "albedo" choice will we make when we replace them?

Avoid accidents-Yes, Stop Global Warming-Hah!

It's good to avoid accidents, not pollute, not waste time and not waste energy. But this won't do anything to stop global warming because man-made emissions have very little contribution to the greenhouse effect (particularly CO2 emissions).

CollisionAlert is what we call our system and yes it can reduce Warming

Sure it is time technologies like this start to get deployed. We had envisioned similar technologies many years ago. Yes Global Warming and Pollution can be affected by a smart traffic control and reducing accidents that clog up roads. Our goal is to use our imaging technologies and GPS to track the existing accidents, avoid accidents, and clear bottle necks.
