Participants and Supporters

We’re proud to bring together partners and supporters who share our desire to change the way we use our built environment for the better. For us, success is about teamwork, and it’s the people who support us that help us make a real difference.



We are proud to be the first to sign up to CUBE. We must find new and innovative ways to reduce energy consumption in our buildings if we are to mitigate the impact of the built environment on climate change. It is the responsibility of us all, individually and collectively, and we hope that many more join this movement and take a positive step on the road to net zero.”

Laura Jockers, Head of Sustainability

The Howard de Walden Estate



“The latest assessment reports from the Intergovernmental Panel on Climate Change have provided the starkest warning yet that immediate action at scale is needed to mitigate against the most extreme impacts of climate change. This warning has not fallen on deaf ears. Numerous companies, countries, cities and regions have stepped up with immediate action plans to deliver net zero, many through joining the UN Race to Zero. 


CUBE is an innovative competition that addresses energy consumption in our workplaces across the UK.  With buildings and construction estimated to be responsible for 25% of the UKs total carbon footprint, real estate has a huge role to play in the national transition to Net Zero. 


Bringing together landlords, building managers, and occupiers, the year-long competition is about working together to tackle the challenge of operational building emissions through collaboration, behaviour change and open dialogue.


We welcome this collaboration to drive down energy demand by some of the UK's leading developers and encourage those not currently in the UN Race to Zero to take action and join the CUBE UK participants who are in the Race: Landsec, Savills and Workspace Group.”


Nigel Topping,

United Nations High Level Climate Action Champion

“Emissions from powering London’s workplaces account for around one third of the capital’s carbon footprint. That’s why the Mayor is calling on businesses to improve the energy efficiency of their buildings and supporting them to do this through programmes like the Business Climate Challenge.


“We’re happy to see the CUBE competition provide an engaging pathway for businesses to play their part. Businesses can show leadership in tackling the climate emergency by urgently reducing emissions from their workplaces."


Shirley Rodrigues,

London Deputy Mayor for Environment and Energy


“Our mission is to make everyone healthier by improving their environment, in turn allowing people and communities to thrive. Our buildings have a huge impact on our health and productivity. As workplaces reopen and teams start to regroup, it is more critical than ever before that landlords and occupiers ensure these spaces make a positive contribution to our wellbeing.  We need innovative ideas to help us do this and, crucially, to change our behaviour to effect change. I’m delighted to endorse the CUBE competition, a great initiative that makes reducing energy consumption and our impact on the environment easy, engaging and fun.  With a spirit of collective responsibility, I hope every landlord and occupier gets involved, proving how much can be achieved when we do it together.”

Josh Artus, Centric Lab


“SIOR Europe is founded on the principles of team work, collaboration and best practice. When it comes to climate action, we know how critical it is to have a common goal and work together to achieve it. We are therefore pleased to endorse a new UK initiative, called CUBE. Established as a friendly, year-long competition, it brings gamification to reducing energy use in our commercial buildings, with proven results in France where it is in its sixth year. We hope to see many landlords, building managers and occupiers getting involved and playing their part.”


Paul Danks, President of the European Regional Chapter, SIOR


“The climate emergency is a priority for everybody, and particularly for the younger generation. With our built environment one of the biggest emitters of carbon and as a membership organisation representing 5,000 young professionals in property, we celebrate and champion innovation that inspires action. CUBE is a great example – already established in France, it’s a competition that helps landlords, building managers and occupiers encourage behaviour change to cut energy use by an average of 12% and up to 55% in a single year. It’s about taking the first step and making a positive impact, all in the spirit of fun and community.”
