Houston Cox recognises the importance of environmental protection and our responsibility to the
wider environment and communities.

We take our environmental responsibilities very seriously and strive to minimise any adverse
impacts that our activities have, particularly in relation to climate change. We aim to make a
positive contribution to the environmental quality of the communities in which we work. We will
comply with all relevant legislation as an absolute minimum standard and aim to continually
improve our performance, implementing good practice on all new projects.

We continually seek to improve our awareness and environmental performance through appropriate
initiatives, controls, purchasing of resources and training of employees.

We regularly review our business practices, management objectives and targets to identify how we
can reduce our requirements for energy and transport and thus reduce our carbon emissions. We are
committed to good practice in respect of recycling and waste minimisation for both ourselves and
our supply chain. We will ensure that the procurement of materials is, where possible, from fully
sustainable sources.
