BASF creates chemistry with a focus on sustainability, combining economic performance with approaches for environmental protection and social responsibility. Around 112,000 employees in the BASF Group contribute to the service to its customers in many sectors and almost every country globally. BASF’s portfolio comprises six segments: Chemicals, Materials, Industrial Solutions, Surface Technologies, Nutrition & Care and Agricultural Solutions. For BASF, climate protection is considered a key task and an essential part of its strategy. BASF supports the objective of the Paris Agreement to limit global warming to below 1.5 degrees Celsius and aims to support climate action by applying innovative solutions to address new challenges. Sustainable procurement is key to achieving this goal.
The ESG BonusMalus tool addresses the challenge of integrating ESG criteria into tender awards by evaluating suppliers' ESG performance on a unified scale, with bonus or malus applied based on ESG scores. Thus contributing to enhancing our stakeholders' awareness of ESG topics.
Solution
The ESG BonusMalus tool evaluates suppliers’ ESG performance through third-party assessments, allowing for a unified comparison scale. Suppliers can earn bonuses from 0.1% to 5.5% based on their scores, with a malus applied for scores under 25 points.

Colleagues from Procurement, Sustainability, and Business Units collaborated to further incorporate sustainability aspects into procurement processes, managing ESG evaluation results, and adding value through the ESG BonusMalus tool. The model is scalable and applicable across industries.
The ESG BonusMalus tool standardizes the evaluation process, providing comparable results on a single scale, and motivates suppliers to obtain certifications through commercial bonuses.

It encourages the adoption of sustainable practices, such as renewable energy use, and fosters improved monitoring and reporting of GHG emissions, creating a culture of accountability. Additionally, rewarding high-performing suppliers encourages long-term partnerships and leads to more sustainable supply chains.
