Our long-term partnerships with suppliers are supported by a robust management system to ensure that business relationships are aligned with all applicable laws and the highest standards for business ethics, health, safety and environmental protection, from the supply of raw materials to transportation and distribution services.
Our suppliers are a central part of our sustainability strategy. We aim to collaborate with our off-site processors, custom manufacturers and over 3,000 suppliers to drive sustainability improvements. We evaluate our suppliers using the independent EcoVadis rating on a broad range of topics, including environmental management systems, human rights and sustainable procurement practices.
This is helping us to understand risks and opportunities in our supply chain, find opportunities for collaboration, and ensure that our supplier base understands our business and sustainability strategy. The share of 2024 supplier spend that was covered by sustainability assessments has risen to 71%, up from 62% for 2023. Our intent is to reach 80% of relevant spend by the end of 2025.
We have integrated sustainability criteria into key procurement processes and continue to engage key suppliers to drive improvements. Product carbon footprint data is requested as part of our tendering process and we have collected data for over 50% of raw material suppliers by volume. We are working with our suppliers to improve the quality and coverage of data through regular steering team meetings and business performance reviews.
