GNT has attained independent ISO 14067 verification for its Exberry natural colour Product Carbon Footprint (PCF) methodology, as confirmed by TÜV SÜD. This validation confirms GNT's cradle-to-gate emissions calculations, encompassing agriculture, production energy, and transportation, meet international standards. The move reflects an escalating industry-wide demand for tangible sustainability data, moving beyond aspirational marketing claims towards quantifiable evidence for ingredient sourcing.
The verification provides supplement brand owners with pre-audited carbon footprint data for 98% of GNT’s Exberry portfolio. This allows for direct application in their own sustainability reporting, product development decisions, and consumer-facing communications. Petra Thiele, Managing Director at GNT Group, underscored that transparency and trust are integral to the company’s sustainability commitment, directly addressing the market's increasing distrust of unverified environmental assertions.
This development is particularly relevant as regulatory bodies and consumers demand greater accountability for product lifecycle impacts. GNT's PCF calculations contribute to broader Scope 1 to 3 emissions reporting, which is already corporate carbon footprint verified under the Greenhouse Gas Protocol. The company also holds an EcoVadis Platinum award, placing it within the top 1% of food manufacturing firms for sustainability performance.
The availability of such data facilitates more accurate assessment of product portfolio emissions and supports brand owners in their decarbonisation efforts. This proactive approach to verifiable environmental metrics will likely become a competitive advantage, especially as the industry continues to reformulate away from synthetic dyes, as evidenced by GNT’s recent petition to the US FDA for safflower-based yellow colour approval.
What this means for United Kingdom
UK supplement manufacturers and brand owners gain a critical advantage for compliance with upcoming ESG reporting directives and consumer demand for transparency. Utilising GNT's verified Exberry colours directly strengthens carbon footprint declarations, improving competitive positioning against brands with unverified claims. This data streamlines the development of 'low-carbon' product lines, appealing to a growing segment of environmentally-conscious consumers. Procurement teams should prioritise suppliers offering similar independently verified environmental data to de-risk future supply chains and enhance marketing narratives. Failure to integrate verified data will result in a competitive disadvantage and potential future regulatory non-compliance, impacting market access and brand perception.
Akshat Rawat, Senior Sustainability Specialist at GNT, stated that verified PCF data empowers customers to maximise product sustainability, aligning with the mission to produce plant-based ingredients for a healthier future. This reinforces the commercial imperative for verifiable data in a market where consumers increasingly scrutinise ingredient lists and demand environmental accountability.
