In the Summer of 2004 Eskmills achieved accreditation under ISO 14001, the international ‘green’ standard.

The achievement of ISO 14001 marks a further significant step for Eskmills as a quality business location operating to the highest environmental standards. This international standard, first published in 1996, was written over five years in consultation with international industrial experts, non-governmental organisations and regulators. Essentially, it helps businesses put in place a management system to minimise their impact on the environment – a worthy objective that all tenants can support. The first step towards ISO 14001, was the installation of a recycling facility, covering paper, cardboard, bottles and cans. This important facility has already helped the Eskmills business community, working in partnership, to reduce the amount of waste they send to landfill and helping to reduce the cost of waste disposal as well as helping the environment. The Eskmills management team has also set up a Renewable Power Buying Group, in which all tenants are encouraged to participate.

All electricity used in the Common Areas, both internal and external, is generated from renewable resources only, and is purchased at extremely competitive prices. At the other end of the scale, Isertal are going to use "Geothermal" heat-transfer technology for the heating and cooling of Archibald Hope House. This technology will make use of water in the ground underneath Eskmills, extracting heat from it during the winter and using it to cool during the summer. Ally this to electricity from renewable resources and Archibald Hope House will be heated and cooled by a system producing zero carbon emissions. Based on the success of this initiative, a similar system may be retrospectively introduced elsewhere at Eskmills in the coming years.

In the the summer of 2003, Lisa Prentice, an environmental science student, worked with to put in place a cohesive environmental strategy, as a step towards ISO14001. Lisa's project is now complete. This year Isertal has again recruited a student, Peter Bruce, for the Summer of 2004. Peter's remit is to review and recommend a programme to ensure Eskmills maximises its biodiversity potential.July 2004
