A couple of weeks ago, I put together a page on Carbon & Climate Change and am
still reelling from my research.

There are some interesting calculators around.

According to the The Greenhouse Accounting CRC's Tree Carbon Calculator, fast
growing softwood pine aborbs less CO2 than hardwood Eucalyptus....but it is
still pretty slow. Ofcourse trees that drop their leaves don't photosynthesise
without their leaves and absorb no CO2 during winter.

There is also some interesting data available on cars and home appliances.
