Do as I say ... oh, I lost count

From the Times of London online, we read this report.

Who are some of these?  To name a few, here are excerpts:

THEY may shout their green credentials from the rooftops, but some of Britain’s most prominent environmental champions are living in homes that produce up to half a ton of excess carbon dioxide a year.

An audit of properties, measuring heat loss, has revealed that Chris Martin, the pop star, Boris Johnson, the mayor of London, and Sir David Attenborough, the broadcaster, are among those who reside in homes that are “leaking” energy. Some lack even the most basic energy saving measures such as cavity wall insulation and double glazing.
...

Simon Hughes, the Liberal Democrat energy and climate change spokesman, owned the least energy-efficient property. He bought his £150,000 flat in Southwark, south London, 25 years ago but has failed to fit it with any significant insulation. Only last week Hughes unveiled plans to make every home in Britain energy efficient within the next decade. He could start with his own flat.
...

Johnson is a late convert to the environmental cause and has sought to enhance his reputation by offering Londoners discounted home insulation.

However, his five-bedroom Victorian house in Islington, north London, loses 1,388kWh of energy a year - equivalent to - largely because of “excessive heat loss” around 360kg of CO2 the upper and lower windows.

Yep, do as I say ...
