Yes we have the ISO14001 standard here for which I am responsible for. The problem is I having been running this for over 5 years now and most new ideas have been dealt with either through objectives and targets which is part of the continous improvement which the standard asks. Or though audits that have been carried out through people such as the carbon trust. These reports take 2 days and the report is 52 pages of improvements and recomendations that have been carried out. So we have run out of ideas! The only ideas that we havent had the time or man power to carry out in depth would be, costings of the system, monitoring and reducing energy usage, spend/payback of environmental projects.
