Earthmark Business Environmental Scores For Brands

why we’re here

We believe making climate-conscious decisions should be easy. Born from a frustration with the complexity of the climate space, Earthmark was founded to bring clarity, impact, and actionable solutions to people and businesses worldwide.

Driving Environmental Impact Through Global Partnerships

After refining our vision through leading startup programmes and competitions with Climate KIC and Carbon 13, Earthmark officially launched in 2022. Since then, we’ve set out to put the environment at the heart of decision-making; partnering with global leaders like O2, Samsung, Etisalat, and VoucherCodes to drive meaningful change.

Rooted in Collaboration, Driven by Sustainability

Based in Oxfordshire and with a team across the UK, France and beyond, we operate with a remote-first mindset. We’re proud members of the Greentech Alliance (a thriving community of 1,000+ innovators) and Oxfordshire Greentech (the business network for a low-carbon future).
