Certification story

Selectaglaze, a specialist designer, manufacturer and installer of bespoke secondary glazing systems, in London and across the UK, has achieved Planet Mark certification.

Achieving the Planet Mark is based on the commitment to continuous improvement in sustainability in its business operations by measuring and reducing its carbon footprint and engaging its stakeholders. 

This is Selectaglaze’s third year of business carbon footprint reporting and Planet Mark certification. Since certifying to Planet Mark, the company has set a target to reduce emissions by 5% annually.

Over the next year, the company will be working towards reducing its carbon emissions and sharing its journey with its community to inspire others. By being more strategic about its environmental responsibility, Selectaglaze will be able to significantly increase its positive impact and hope to encourage continual improvements within its community.

Through Planet Mark, it has protected an area of endangered rainforest thanks to Cool Earth; a charity working alongside rainforest communities to halt deforestation. Its pledge through Cool Earth directly supports the Asháninka community in Central Peru.

It has also helped the Eden Project – an educational charity building connections with each other and the living world, exploring how we can work together towards a better future.

Founder and CEO
Planet Mark
“Selectaglaze has made significant steps forward this year, and I applaud the team for their efforts. Glazing is an industry with an increasing focus on climate, and Selectaglaze has taken the opportunity presented with both hands. Such a large reduction in emissions is a real statement, both to competitors and clients, that Selectaglaze is serious about sustainability.”

Certification story

Selectaglaze is committed to sustaining a successful and ethical business by minimising the environmental and social impact of its activities. The company has a number of initiatives to support these goals, such as selecting vehicles with ultra-low emissions or as low emissions as is practical and ensuring all timber and paper products are Forest Stewardship Council certified. The company also seeks to engage its supply chain by identifying local and ethical suppliers for products and cutting business travel emissions, as well as spreading best practice recommendations through its network of employees.

The operations and management of buildings have recently received deserved focus for their role in combating carbon emissions. Emissions cuts in building use are both important and achievable. Contractors and suppliers must take note, and realise the opportunity for truly sustainable change. This requires not only the creation of products that help cut carbon emissions but also business processes to produce in a sustainable manner. 

Future targets

As part of the Planet Mark certification, Selectaglaze has committed to making a year-on-year reduction.
