NQMS for Land Contamination Management
The National Quality Mark Scheme for Land Contamination Management (NQMS) is developed by the National Brownfield Forum to provide visible identification of documents that have been checked for quality.

Since the beginning, CL:AIRE has always had a heavy focus on sharing knowledge throughout industry. We continue to perform this role in a number of ways including the development of the online Water & Land Library (WALL) which has become the primary and ever growing location for relevant industry guidance and support material.

CL:AIRE runs traditional classroom and online training events and courses. We develop guidance documents and materials to benchmark industry standards. We work with a number of international organisations to increase the reach of our output and the CL:AIRE network.

CL:AIRE has two types of Members: Supporters and Principal Members and CL:AIRE supports its members in a range of ways.

Our regular eAlerts keep them up-to-date with industry relevant news and events but also on the development of our industry initiatives.

Our Principal Members are given the opportunity to become directly involved in our industry-led initiatives by joining our working groups. Bringing the industry together is a core part of our membership scheme and we achieve this through regular informal networking events but also by using online social media discussion groups.

We help promote the good work and success of our members through these channels and we provide a webinar platform for members who have interesting projects or news they wish to share with the CL:AIRE Network.

CL:AIRE also has many University Members and works with them to raise the profile of the industry to the next generation of experts.

CL:AIRE works with industry, through its membership to identify, common problems in the field of sustainable land management. Using its extensive experience of developing industry-led initiatives, it works with highly respected experts and government to develop solutions which are tested and critiqued by our Members to ensure they are fit for purpose.

CL:AIRE has a strong track record of carrying out industry relevant research projects, the findings of which are often used for the benefit of industry or fed into our initiatives.

CL:AIRE provides technical secretariat services for a number of industry wide programmes such as the National Brownfield Forum and the National Quality Mark Scheme.
