What Moveandstay does to protect the environment

Following my previous post, I summarize below what we do at Moveandstay to protect the environment:

1. Most of our staffs are using public transportation, bicycle or rollerblades to go to the offices
   
2. We are a near to paperless office
   
3. Our computers from Apple are environment friendly and are easy to recycle
   
4. We recycle papers, cans, plastic bottles, etc
   
5. We switch off any unnecessary lighting during the day
6. We use long-life light bulbs
7. We use reusable crockery and glasses as opposed to plastic cups and disposable plates/cutlery
8. We switch off all equipments before leaving the offices (lights, printers, computers, routers, etc)
9. Recently we paid a little more our flight ticket to Easyjet to compensate our carbon emission during the flight (52 kg of CO2 generated /person for a trip from Paris to London)
   

Do you have more ideas we could use to protect the environment?
