Addressing environmental issues is a big topic. There are many different ways to approach these issues, some based on individual actions and others on collective actions, some passive, some active. the greentomato way is to live our lives and build businesses according to a set of values that we think are pragmatic and can make a real difference. But we are always keen to hear new ideas, to challenge our assumptions and to improve and accelerate our progress. We think improving the world should be an inclusive, democratic process underpinned by transparency and debate. We believe any genuine attempt to improve the world we live in should be listened to and discussed. We provide a platform for these debates through an open blog.  Let us know what you think on our blog page.

Given how much energy it takes to produce food, it’s better to drive than to walk.

Truth: The average diet has an embodied energy of 6kWh of fossil fuel per kWh eaten. The energy use of a typical car is 80 Kwh per 100 km. Walking uses a net energy of 3.6kWh per 100 km, 22 times less than driving. This means that if you have a typical diet, the carbon footprint of the food required to walk 100 km is 21.6kWh - still significantly less than that used by a typical car to travel the same distance.
