Environmental consultancy and strategy services

Assessment and monitoring to prevent and mitigate environmental impact, to achieve compliance and ESG goals.

To understand your environment and the impact your operations have on it you need a partner you can trust to provide strategic advice.

We help organisations understand and monitor the environment to reduce risk and enhance performance, so that they can ensure compliance and environmental quality, increase biodiversity, and achieve their sustainability, development, and investment goals, through expert advice and bespoke, pragmatic, commercially focused solutions.

Hazard vs risk

A hazard has the potential to do harm to you or the environment. A risk is the likelihood of a hazard causing harm.

The Source–Pathway–Receptor model

Our consultants operate using the Source–Pathway–Receptor model to identify pollutant linkages.

The model describes the flow of environmental pollutants from a source, through different pathways to potential receptors. An environmental risk will contain all three. A source describes the source of pollution such as a spillage incident. The pathway allows the hazard to cause harm. A receptor is something that could be harmed like a river. All three together creates a pollutant linkage.
