Eating out causes more emissions than home cooked food. 

Don't deny yourself the odd meal out, but consider taking a packed lunch to work. You'll save a surprising amount of money too. 

It is difficult to quantify the carbon savings of some Actions. In this case we allocate a nominal CO₂e per year. This is not reflective of the actual potential savings but to show that you are making a difference.  If possible we will provide representative calculations at a later date.
