Dabbling with greenery

I suppose we should be pleased. But might one suggest that what is proposed represents a fairly modest adaptation to one's lifestyle? The Guardian reports:

Prince Charles yesterday pledged to reduce the royal impact on the environment through sweeping changes to his personal lifestyle and official schedule.
The prince will replace carbon-heavy private jets and helicopters with scheduled flights and train services.
Next week, he will take delivery of Jaguar cars adapted to run on biodiesel fuel, while royal residences such as Highgrove in Gloucestershire will switch to green electricity...
The changes to the prince's travel arrangements announced yesterday are part of a wider review of the carbon footprint associated with activities at all three of his residences: Clarence House in London, Highgrove and Birkhall on the Balmoral estate, as well as the activities of his 21 personal and 105 full-time staff.

After all, how many Jaguars does one need? Perhaps one could also save energy on all the boiled eggs? See here.
