Beef and Cheese are two of the highest sources of greenhouse gas emissions of all food products. Other protein sources such as poultry, eggs, soy and pork are not as highly emitting but are far higher than non-protein sources.
For fruit, the biggest emissions impact we can make is in changing the method of transportation and the number of total miles product travels to get to our kitchens.
Coffee roasting is a very energy intensive process and coffee has to be transported long distances to get to out coffee urns. Smart brewing practices will reduce the amount of energy-intensive coffee from being wasted.
Enormous amounts of energy are used to make food, from farm to factory or kitchen. Wasted food represents wasted energy - fossil fuel energy that creates greenhouse gases.
