About Hiyield
Hiyield: Climate-Conscious Digital Product Studio
Hiyield is a 22 person tech agency, committed to creating websites and web apps for clients as sustainably as possible. Founded in 2017 and based in Cornwall, Hiyield is a certified B Corp and combines digital innovation with environmental responsibility.
Challenges and Growth
For Hiyield, one of the biggest hurdles was finding a way to measure and reduce the carbon footprint of creating websites and web apps. To many people digital products seem intangible, but they have a significant environmental cost due to the energy needed to store and serve data.
Hiyield tackled this challenge by developing a system to calculate the carbon impact of each website and app it builds. Every website and app built by Hiyield comes with a detailed carbon and emissions report, showing clients the energy it takes to build and host their platform. This transparency helps clients make informed decisions about their digital presence.
After measuring the emissions, Hiyield offsets them through tree planting and rewilding schemes.
100% Renewable Hosting
In 2025, Hiyield took a major step towards reducing its environmental impact by transitioning over 50 client websites to Positive Internet Company, a UK-based hosting provider that has been powering its servers using 100% renewable energy from its own on-site wind farm since 2010. Positive Internet’s innovative server cooling systems cut energy use by 40% and they are actively rewilding the land surrounding its data campus. This shift allows Hiyield to offer its clients sustainable hosting without compromising on performance or reliability.
Leading the Conversation on AI and Sustainability
Hiyield is also working to help the wider tech industry adopt more sustainable practices. In 2025, the company released a report called Is AI the enemy of sustainability? in partnership with the University of Exeter. The report surveyed businesses and experts to understand AI’s environmental footprint and provided guidance on how businesses can adopt AI more responsibly. From optimising AI models to choosing renewable-powered infrastructure, the report has helped guide businesses within sustainable tech.
Environmental Impact
Hiyield’s commitment to sustainability has had a measurable environmental impact. The transition to renewable hosting alone has reduced the carbon footprint of over 50 websites. Through its tree planting and rewilding schemes, Hiyield has supported the restoration of natural habitats and the removal of CO₂ from the atmosphere. The company’s AI and sustainability report has also influenced other businesses to adopt more mindful AI practices, amplifying its impact across the tech sector.
A Business Built on Values
Hiyield’s commitment to sustainability extends beyond client work. As a B Corp, the company holds itself accountable to high standards of social and environmental performance, transparency, and legal accountability. From supporting remote working to reducing office energy use, Hiyield continually seeks ways to improve its impact.
Hiyield demonstrates that technology and sustainability can go hand in hand. By building innovative digital products with a focus on reducing environmental impact, Hiyield is helping businesses create a better future, one line of code at a time.
