Kal Tire’s Mining Tire Group has achieved independent ISO verification for the carbon footprint methodology behind its KalPRO™ Maple Program.
ISO Verification for Maple Program
The verification is intended to provide customers with confidence that the carbon savings reported through the Maple Program are transparent, credible, and based on recognised greenhouse gas accounting principles. The programme calculates the environmental benefits associated with choosing tyre life extension solutions, such as repairs and retreading, instead of purchasing new tyres.
SCS Global Services completed the third-party review. The Maple Program methodology was evaluated against the requirements of ISO 14067:2018, the international standard for product carbon footprints, with the independent verification conducted in accordance with ISO 14064-3:2019.
Introduced in 2019, the Maple Program provides participating mining customers with annual certificates detailing the calculated carbon emissions and oil savings achieved by choosing Kal Tire repair and retreading solutions instead of replacing tyres with new equivalents. Companies can use the data in sustainability reporting.
“Mining companies are increasingly looking for reliable data to demonstrate the environmental impact of the decisions they make across their operations,” said Miles Rigney, Senior Vice President of Kal Tire’s Mining Tire Group. “This verification helps reinforce the role tyre management can play in that broader picture, particularly as mines look for practical ways to reduce waste and make better use of high-value assets.”
The Maple Program includes conventional repairs, KalPRO Ultra Repair, retreading, and KalPRO Ultra Tread for mining tyres ranging from 25 to 63 inches. The programme is built on a lifecycle carbon footprint methodology developed from more than 25 years of Kal Tire repair and retreading data. The methodology calculates the difference in carbon emissions between two options that provide the same tyre service life: replacing a tyre with a new equivalent or extending the existing tyre’s life through repair or retreading.
“Extending the life of a mining tyre can avoid the need to manufacture and transport a replacement tyre earlier than necessary, but it is important that the environmental benefit is quantified in a consistent and robust way,” added Rigney. “The Maple Program turns those tyre decisions into measurable data customers can use in Scope 3 reporting. In 2025, approximately 70 mining customers across six regions reported saving more than 32,700 tonnes of calculated CO₂ emissions.”
The ISO verification marks a further development for the programme, which has helped mining operations quantify the environmental value of tyre life extension since 2019. As mining companies place greater emphasis on understanding emissions across their supply chains, Kal Tire said reliable measurement would become increasingly important in demonstrating the contribution tyre management strategies can make to sustainability objectives, including extending tyre life, reducing waste, and improving the environmental performance of tyre operations.
