We run a Mondeo mk4 estate with a Euro 5 engine and always try to buy our fuel from Shell as they run a carbon neutral scheme to offset customers fuel.

We have gas and electricity suppliers who only generate 100% renewable electricity
and 100% carbon offset gas. We also have solar panels on our roof to generate our own electricity.

We recycle all our cardboard from goods in and the cardboard tubes from the middle of the vinyl rolls. From manufacturing we recycle the covering/application paper too. We would like to recycle the silicon backing paper but we do not get enough of it for recyclers to collect it.
