As the world grapples with climate change and seeks to diminish its carbon footprint, the evolution of CleanTech – technology that seeks to boost productivity, efficiency, and profitability, all while reducing costs and impact on the environment – becomes increasingly crucial. With UK’s commitment to reducing its greenhouse gas emissions by at least 80% (relative to 1990 levels) by 2050, and its ambitious goal of net-zero by 2050, the nation has arguably one of the most vibrant Cleantech sectors globally. In this piece, we introduce fifteen British CleanTech startups making a difference in various industries, from manufacturing, e-commerce, transportation, to fitness.

For the uninitiated, the term ‘CleanTech’ encompasses a wide range of products, services, and processes, all utilizing renewable materials and energy sources, dramatically reducing emissions and waste, and having a minimal impact on the environment. As the industry grows, so does its potential to disrupt and reshape industries, clean up our environment, and enhance corporate sustainability.

These fifteen British startups, each unique, driven by innovative ideas, and environmental responsibility, provide a snapshot of the exciting work that CleanTech startups are capable of.
