STL Communications has advanced its green ethos by joining Co-Caa, the Carbon Offset and Climate Awareness Association.

STL's GreenMinutes is a carbon neutral initiative that enables customers to offset their carbon phoneprint and to work smarter using a range of free eco features.

Phil Donigan, STL's Sales Director, stated: "The environment is a key part of STL's ethos and is embraced by all our staff. Membership of Co-Caa is another way of demonstrating that we have measured our greenhouse gas emissions and have reduced them through internal change."
