HTA marks five years of Planet Mark certification

The Horticultural Trades Association (HTA) is celebrating its fifth consecutive year as a Planet Mark Certified Business, reinforcing its long-term commitment to sustainability. The milestone also marks two years since installing solar panels on the HTA’s office roof—contributing to reduced emissions and lower energy costs.
Since beginning its carbon emissions tracking in 2020 with Planet Mark, the HTA has focused on robust measurement and meaningful reductions, despite the initial challenges of the pandemic. The organisation continues to support its members while embedding sustainability across operations.
Between 2023 and 2024, the HTA achieved a 14% reduction in Scope 2 (location-based) emissions, thanks in part to the 75,000 kWh of clean energy produced by its solar panels. This equates to an estimated carbon saving of 14.4 tonnes since their installation in July 2023.
Liz Williams, HTA Sustainability Executive, highlighted the importance of tracking progress: “Our solar panels are already making a big difference... We cannot manage what we do not measure.” She also reaffirmed the HTA’s commitment to Planet Mark’s Net Zero Certification Programme.
The HTA is now focusing more closely on its Scope 3 emissions—those generated indirectly across its supply chain—starting with a June workshop led by Planet Mark. This step marks the beginning of a comprehensive carbon inventory and reduction roadmap.
Steve Malkin, Planet Mark CEO, praised the HTA’s efforts: “Their committed approach demonstrates leadership in sustainability across the horticultural industry.” The HTA will continue working towards an annual 5% reduction in Scope 1 and 2 emissions, helping to shape a greener future for the sector.
