Madam, - We all remember the years just before the new millennium with businesses and governments all over the world morally and economically blackmailing each other by issuing notices to the effect that they would not conduct transactions unless they were certified to be Y2K compliant.
So why not make a small start with a notice stating that a company, organisation or individual was concerned about global warming, or "GWC" and stating what they were doing to help achieve lower carbon emissions, effective energy use, etc? - Yours, etc,
