Deep dive


Planet Mark is a leading sustainability service provider dedicated to supporting organisations in reducing carbon emissions and embedding long-term environmental responsibility. At the core of its offering is the Planet Mark Certification, an annual programme that provides independently verified carbon measurement across Scopes 1, 2, and increasingly detailed Scope 3 categories. This certification ensures transparency, credibility, and consistency, helping organisations understand their environmental footprint and set ambitious reduction targets.

Beyond the certification itself, Planet Mark delivers a broad range of consulting and advisory services, including Net Zero strategy development, decarbonisation pathway planning, materiality assessments, and sustainability reporting guidance. Its team provides hands-on support to help companies integrate sustainability into business operations, supply chains, governance structures, and employee culture.

The organisation also places strong emphasis on communication and engagement, offering training, workshops, impact storytelling, and branded materials that help organisations mobilise internal teams and share progress with stakeholders. This includes support for sustainability disclosures and alignment with frameworks such as the GHG Protocol, SBTi, and legislative reporting requirements.

Planet Mark additionally provides digital tools, such as a members’ platform and data analytics resources, to streamline measurement and reporting. However, these tools function primarily as enablers of the service, rather than standalone software products.

By combining verified data, expert guidance, community learning, and strong communication support, Planet Mark equips organisations to deliver credible climate action, make measurable progress toward Net Zero, and demonstrate real environmental leadership.
