Our purpose

Since our launch in 2013, Planet Mark has been on a mission to empower change for a brighter future.  

To do that, we begin by measuring what matters, providing the insight needed to make informed decisions about when and how your organisation will make the transition to a net zero model.  

Alongside this, we educate and inspire your people acting as a catalyst for behaviour change that not only immediately reduces carbon emissions but drives cost savings through lowering consumption.   

Communicating your Planet Mark Certified Business status further supports customer preference for your brand and provides tangible and impartial verification that your organisation is making progress in relentlessly reducing carbon and is committed to #DoMoreGood.

What we do

We are a sustainability certification and net zero provider for organisations and the built environment. 

For over a decade, we have supported organisations to radically reduce carbon emissions, create operational efficiencies, enhance profits and work towards the global transition to net zero.

on policy and legislation

From being consulted by Governments on net zero policy development, to proactively supporting the creation and roll-out of the ISO Net Zero Guidelines and helping to develop the UK Net Zero Carbon Buildings Standard, Planet Mark remains at the forefront. 

This has led to Planet Mark being one of only ten official Partners of the UN-backed Race to Zero campaign supporting businesses on their net zero journeys.


We value a transparent and authentic approach to sustainability. Planet Mark’s third-party verification for our carbon impact and social value helps us demonstrate our credentials, benchmark our progress and proudly show our pledge toward continued improvement. Our stakeholders can be reassured by our commitment that fits with our wider strategic aims: to achieve net zero; to green our supply chains; to embed a culture of sustainability throughout the wider group and to minimise waste.
