Carbon footprints measure how much carbon dioxide (CO2) we produce just by going about our daily lives. It is the measure of the environmental impact of a particular individual or organization’s lifestyle or operation, measured in units of carbon dioxide.
“Dealing with global warming doesn’t mean we have all got to suddenly stop breathing.” – David Attenborough
A carbon footprint is composed of two parts, a primary and secondary footprint. When fossil fuels burn, they emit greenhouse gases like CO2 that contribute to global warming – this is the primary footprint. Ninety-eight percent of atmospheric CO2 comes from the combustion of fossil fuels. The secondary footprint is the sum of indirect emissions associated with the manufacture and breakdown of all products, services and food an individual or business consumes.
“I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.” – Michael Crichton
