Food production, packaging and transportation consumes energy and results in carbon emissions which threaten to raise average global surface temperatures.
It has been suggested that our food is responsible for 20% of the UK's entire carbon footprint. Each one of our bodies burns an average of about 100W and hour, ie 2.4kW/day.
But not all foods are equal.
The Food Carbon Footprint Calculator (FCFC) allows you to calculate the resultant carbon dioxide from the food you eat. One way of reducing that carbon footprint is to eat seasonally, locally, and limit the amount of meat in your diet.
Not everything is about food miles, sustainable forms of export agriculture contribute to the economic and social development of poor producers. For example, although Fairtrade products are imported from around the world their standard requires producers to make environmental protection a part of farm management.
An estimated 12.7 million tonnes of plastic end up in our oceans each year and there are a number of organisations working to change our attitude to plastics including campaigns such as GreenPeace's Plastics Pledge aimed at corporations and Governments, Plastic Planet's #PlasticFreeAisle aimed at reducing the plastic packaging used in supermarkets and WRAP's circular economy Re-defining plastic work.
