Carbon sequestration and lawns

One of the message boards I belong to is a food and climate change group. Recently a discussion thread there addressed the issue of lawn care and carbon sequestration. It brought to mind the reality that perhaps 1% of our population is aware and concerned about problems the other 99% of us are either ignorant of or can't be bothered with. An essential question in all issues such as this; should public policy follow the lead of the 1% or wait for the other 99% to catch up? Obviously, the 1% would hope - perhaps vainly - that public policy would be that progressive. For the benefit of we 99%, I offer this from Lori of the climate change group:

The simplest effort that can reduce fossil fuel consumption associated with healthy lawn care is mowing with a sharp mower blade as it can reduces mower gas consumption by 25% or more: http://www.gardening.cornell.edu/news/mow_sharp.htm The next simplest task is raising the mower blade to it's highest setting (~3 in.) so you mow less often. Even the most avid lawn care enthusiast could live with the beautiful healthy lawn that can be achieved with these simple pesticide free steps. For those looking for more steps for educating the public about eco-lawn care this site has lots to offer: http://www.growinggreenlawns.org/publications/
