Carbon Footprints
Carbon footprints - which measure the amount of carbon (other GHG emissions) produced to directly or indirectly support any activity in equivalent tons of CO2 have become a bench mark. For eg. when you buy an Walkers crisp, carbon has been burnt during its production,packaging, transportation etc. Therefore the overall Carbon Footprint of a crisp is calculated by summing up all the carbon expanded during its lifetime.
In recent times carbon footprints have wielded great significance with its effect on increasing world temperatures and resulting climate change. 72% of the totally emitted GHG (Green House Gases) is CO2. Carbon footprints therefore measure the contribution of a product towards Global Warming. Countries like US, China, Russia, Japan, India and Germany have the largest CO2 emission levels with US also leading in the per capital CO2 emissions.
Walkers Carbon Footprint
Carbon trust on the behalf of Walkers have calculated the carbon footprint of a standard packet of Walkers Cheese and Onion crisps. They have taken into account various stages in the life cycle of a Walkers Crisp starting from sowing of potato and sunflower seeds to disposing of the packet. The final carbon footprint calculation is 75g.
The stages involved in calculation :
- Raw Materials : Potato, Sunflower and seasoning.
- Manufacture : Producing crisps from potato.
- Packaging.
- Distribution.
- Disposal of the packets.
