THE CYCLE – COUNT AND ANALYSE

INDIVIDUALS
For individuals, carbon calculators simplify compiling an inventory. Typi-
cally you will need to know your electricity consumption in kWh, how
much and what kind of fuel you use to heat your water and warm the
house, and how many kilometres you drive, fly and ride in different ve-
hicles. You also need to decide the limits of the system you are concerned
with, whether it is you as individuals, your household, or the company
you work for.
And that still leaves unsettled the range of the emissions you are prepared
to acknowledge. It may be simply those for which you are directly respon-
sible – the fumes that come out of your car’s exhaust and the emissions
from your central heating. But you may decide to set your bounds much
wider and incorporate at least some of the gases
“embedded”
in every-
thing you use or buy. But the more you include the more complex your
task to measure the emissions will become. While you might lose in ac-
curacy, you are more certain not to ignore a big chunk of your emissions.
Probably the simplest rule is to include those emissions you control and
those resulting from the products and services you pay for. It will not give
you a perfect answer or even a complete one, but it will let you make a
start, from which you can hope to improve your performance later. Just
under half the emissions for which those individuals in developed coun-
tries are responsible come from things over which we have some con-
trol, for example how much we drive and fly and how we heat and power
our homes. The rest arises indirectly from powering the places where we
work, from maintaining public infrastructure and government, and dur-
ing the production of the things we buy, including food. These are some
of the factors that anyone will want to think about as they decide how to
start their climate diet.
Carbon and climate labels might in future help to identify indirect emissions. Giv-
en the complicated life cycle of products, however, one may imagine how difficult it
is to create an accurate label at product level, let alone compare different products
with each other. A carbon label, which shows the carbon footprint inherent in put-
ting a product on the shelf, was introduced in the UK in March 2007 by the Carbon
Trust. Examples of products featuring their carbon footprint are Walkers Crisps,
Innocent Drinks, and Boots shampoos.
