Even our Congress possesses a CO2 "footprint". By purchasing CO2 Certificates we’ll be neutralizing the CO2 the rheingold Congress emits and acting in a climate-neutral way. Of course, this doesn’t mean we won’t be producing any greenhouse gases. However, it does mean that we won’t be ignoring the reality of global warming, and helping to stop climate change by making a contribution to the development of environmentally friendly technologies in developing countries.
