Net zero at Pi Towers: how we’re doing it

At Raspberry Pi Ltd, we’re seeking to be pioneers in transforming our property portfolio to reach net zero. Net zero at Pi Towers: how we’re doing it. With the buzzword ‘net zero’ falling from people’s mouths wherever you go — especially following what has been the hottest and driest summer on record — it feels as relevant as ever to share what we’re doing at Raspberry Pi.

As businesses and individuals, we all have a responsibility to care for our planet, and here in Cambridge we’re trying to walk the walk, not just talk the talk. 85.5kW of solar panels visible on the roof at Pi Towers At Raspberry Pi Ltd, we’re seeking to be pioneers in transforming our property portfolio, ensuring we remain productive and supportive of growth whilst harnessing technology that moves us away from contributing to the carbon problem. Since our last blog post in 2025, where we set out four ambitions towards net zero, we’ve been on a journey to execute the plan.

So, here’s a quick update on how things are going, what we aim to achieve this year, and what I hope to be able to report in the next post. Our four ambitions were: To introduce solar PV and reduce our electricity consumption To introduce and encourage EV transport for staff To turn off the gas To reduce our electrical base load Solar Our 85.5kW array went live in June 2024, and has now generated 192,000kWh in just 26 months. Staggeringly, we’re on track to see a full return on investment in the very near future, at around 2.7 years.

We’re using a lot of power, so we’ve set our sights on expanding the array at our Cambridge office with a 219kW solar carport system, with the support of our landlord’s agents, Stanhope.
