GreenZone Cleaning & Support Services’ total carbon footprint in the year ending December 2020 was 70.8 tCO2e, a reduction of 25.4% compared to the previous year. GreenZone Cleaning & Support Services’ total carbon per employee in the year ending 2020 was 1.2 tCO2e, a reduction of 9.3%.

Steve Malkin
Planet Mark
“GreenZone is a Planet Mark stalwart, an early pioneer of sustainable practice and an embracer of change. GreenZone takes a wholesale approach to sustainability, from landmark statements such as the electrification of its fleet to the minor details, low-carbon operations are at the centre of every business decision. Companies from all industries could learn from this approach. This year is just one of many successes in carbon reduction for GreenZone, and each year makes me more proud to work with their team.”
Steve Trew
Managing Director
“From inception, our mission has been to ensure everything GreenZone does revolves around social, economic and environmental sustainability, ensuring our operations leave a positive legacy on our planet. We are thrilled to have achieved our 9th consecutive year of certification through the Planet Mark, validating our long-term commitment to carbon footprint reduction and our contribution to the global effort for halting climate change.”

Certification story

GreenZone aims to achieve new benchmarks in sustainability, inspire behavioural change and minimise the environmental impact of its operations. From the electrification of its fleet and promotion of public transport to introducing cutting edge technologies to create a truly chemical free cleaning experience, GreenZone embeds sustainable throughout its business operations. The company believes that being green is not just a bolt-on to business; it’s how to do business. 

The cleaning industry is ripe for widespread change in the decade of climate action. The industry must take closer notice of its supply chain, learning about the impacts of chemicals in many cleaning agents. As popular opinion continues to want greater environmental awareness, cleaning companies must stay on the front foot regarding sustainability for client retention and acquisition purposes. 

Future targets
