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.

Flying is ok because aviation only produces a few percent of global CO2 emissions.


Truth: Globally, it is true that aviation does not produce more than a few percent of CO2. However if you take a single intercontinental flight every year, this is likely to dominate your own personal CO2 emissions.
More importantly, emitting the gas high up in the atmosphere means that the global warming effect of every tonne of CO2 emitted by a plane is 2-4 times worse than that of the same tonne emitted on the ground!
Another problem is the speed of growth of the aviation industry: between 1990 and 2001, UK passenger numbers increased by 73%. Over the same period, average fuel consumption per passenger per kilometre travelled actually increased by 12%!  In 2008, aviation was responsible for 23% of transport fuel use in the UK.
