If enough businesses act, together we can slow down or help to prevent Global Warming.
We estimate that widespread adoption of more climate-friendly policies in industry globally, could have the equivalent impact of taking 630.5 million cars off the roads.
Just a few examples where we have the know-how to do things differently and help both the environment and the bottom line.
The case for a great return on investment, from water and energy savings is very clear. "Adopt an Investment Policy to Prevent Global Warming".
