What’s Required
Covestro’s supplier framework is a mature chemicals-sector private regulatory system. It combines contractual supplier standards, procurement integration, supplier assessments, Scope 3 decarbonisation, product carbon footprint work, alternative raw materials and chemical-sector sustainability initiatives.
The framework is built around:
Covestro Supplier Code of Conduct.
Sustainability in Procurement Programme.
supplier assessments and audits.
Together for Sustainability, or TfS.
Supplier Engagement Program, or SEP.
Scope 3 greenhouse gas reduction target.
product carbon footprint data collection.
circular economy strategy.
alternative raw materials, including recycled and bio-attributed inputs.
renewable energy and green electricity sourcing.
environmental, health, safety and human rights controls.
integration of supplier requirements into contracts and electronic ordering systems.
Covestro states that sustainability in supplier management is designed to ensure that business with suppliers aligns with environmental, social and ethical standards. Its Supplier Code of Conduct sets out the key social, ecological and ethical standards Covestro expects suppliers to share.
1. Supplier Code of Conduct as contractual baseline
Covestro’s Supplier Code of Conduct is the foundational compliance document for suppliers. It is based on the UN Global Compact and the company’s Human Rights Policy Statement, and Covestro expects suppliers to respect and implement its standards.
The Code addresses core supplier expectations across:
environmental protection.
human rights.
labour standards.
health and safety.
ethical business conduct.
legal compliance.
anti-corruption.
management systems.
responsible sourcing.
circular economy and resource responsibility.
The supplier-code logic is procurement-based. Covestro’s 2023 reporting stated that the Code is integrated into electronic ordering systems and contracts across the Covestro Group. This means the Code is not only a statement of values. It becomes a contractual and ordering-system condition for doing business with Covestro.
For suppliers, this creates a compliance baseline requiring documented systems, not just policy alignment. Suppliers must be capable of proving that environmental and social obligations are understood, implemented and monitored.
2. Sustainability in procurement and supplier assessments
Covestro’s procurement framework treats sustainability as part of supplier management. The company states that compliance with sustainability standards in the supply chain is fundamental and that supplier management aims to align procurement with environmental, social and ethical standards.
Supplier requirements may include:
supplier self-assessments.
TfS assessments.
ESG documentation.
audit participation.
corrective action plans.
environmental management evidence.
human rights and labour evidence.
safety documentation.
supplier code acceptance.
sustainability data provision.
Covestro has historically targeted systematic assessment of suppliers with significant purchasing value, while requiring other suppliers to comply with the Code through contracts and orders. A Covestro supply-chain sustainability Q&A explained that suppliers with repeat purchasing value above €100,000 were assessed and had to comply with sustainability standards, while other suppliers had to accept the Code through contracts and orders.
This creates supplier segmentation. High-spend, high-impact or high-risk suppliers face more detailed assessments and monitoring. Lower-risk suppliers remain covered through baseline contract conditions.
3. Together for Sustainability and chemical-sector standardisation
Covestro participates in chemical-sector sustainability initiatives such as Together for Sustainability, which is highly relevant because TfS functions as a common supplier assessment and audit infrastructure across the chemical industry.
For suppliers, TfS-style governance can require:
standardised sustainability assessments.
audit readiness.
corrective action follow-up.
environmental management evidence.
labour and human rights documentation.
ethics and compliance systems.
health and safety records.
emissions and energy data where relevant.
comparable performance information for multiple chemical customers.
The significance is sector-wide. A supplier assessed through TfS is not responding only to Covestro. It may be evaluated under a common chemical-industry framework that affects access to multiple customers. This is private regulation at industry scale.
4. Scope 3 emissions as supplier governance
Covestro has made Scope 3 emissions a central supplier governance issue. The company states that Scope 3 emissions cover upstream and downstream supply chains and represent around 80% of Covestro’s total greenhouse gas emissions. Covestro has set a target to reduce Scope 3 emissions by 10 million metric tons, equal to a 30% reduction compared with 2021, by 2035, and to reach net-zero Scope 3 emissions by 2050.
This has direct supplier implications. Suppliers may need to provide:
Scope 1 emissions from their own operations.
Scope 2 electricity and energy emissions.
Scope 3 information where material.
raw-material carbon intensity.
feedstock emissions factors.
renewable energy data.
logistics emissions data.
product carbon footprint inputs.
process emissions information.
evidence of reduction programmes.
data on circular or alternative feedstocks.
Covestro’s annual report procurement section states that the company identified main sources of Scope 3 emissions, used a heatmap to contact parties driving those emissions, discussed emissions reduction programmes and targets with suppliers, and gathered feedback on supplier-specific product carbon footprints under its Supplier Engagement Program.
This is highly significant. It means Covestro is not treating Scope 3 as only a reporting estimate. It is using supplier engagement to identify emissions drivers and obtain product carbon footprint data from suppliers.
5. Supplier Engagement Program and product carbon footprint data
The Supplier Engagement Program is a core operational mechanism. By contacting suppliers that cover most raw materials and gathering supplier-specific product carbon footprint feedback, Covestro is moving toward product-level climate governance.
Suppliers may need to support:
supplier-specific product carbon footprint calculations.
site-specific or product-specific data.
cradle-to-gate emissions information.
allocation methods.
emissions factor transparency.
renewable energy evidence.
feedstock origin data.
mass-balance documentation where relevant.
methodology alignment.
data quality improvement.
For chemical suppliers, product carbon footprints are technically complex. Emissions must often be allocated across multi-product processes, co-products, steam crackers, intermediates, batch production, utilities, logistics and feedstocks. Suppliers with weak allocation methods or poor primary data can create significant uncertainty in Covestro’s product carbon data.
6. Circular economy, alternative raw materials and feedstock governance
Covestro has placed the circular economy at the centre of its strategy. Its Supplier Code describes circular economy as the company’s vision and pathway for addressing climate neutrality and plastic reuse, identifying green energy, alternative raw materials, innovative recycling technologies and partnerships along the value chain as key building blocks.
This creates supplier requirements around alternative feedstocks and circular inputs.
Suppliers may need to provide:
recycled feedstock origin data.
bio-based or bio-attributed feedstock data.
renewable raw material documentation.
mass-balance records.
chain-of-custody evidence.
ISCC PLUS or equivalent certification.
waste-stream quality data.
contamination controls.
lifecycle emissions data.
product specification evidence.
proof supporting circular or lower-carbon claims.
Covestro has expanded circular-economy products using mass-balanced materials derived from recycled and bio-attributed inputs, enabling customers to reduce carbon footprints and Scope 3 emissions. This means upstream suppliers of recycled, renewable or bio-attributed inputs must provide robust documentation because Covestro’s customer claims depend on credible chain-of-custody and carbon data.
7. Renewable energy and operational supplier impacts
Covestro’s Scope 1 and 2 targets are to reach climate neutrality by 2035, while its Scope 3 target is net zero by 2050. Its sustainability goals page states that Scope 1 and 2 emissions are targeted for net zero by 2035 and Scope 3 by 2050.
Although Scope 1 and 2 are Covestro’s own operations, suppliers are affected because decarbonised production and circular products depend on renewable energy, low-carbon utilities, equipment suppliers, engineering contractors and energy service providers.
Relevant suppliers include:
renewable electricity providers.
energy infrastructure suppliers.
industrial equipment suppliers.
efficiency technology providers.
engineering contractors.
maintenance suppliers.
utility and steam suppliers.
digital optimisation suppliers.
Suppliers may need to provide:
energy performance data.
renewable electricity certificates.
equipment efficiency documentation.
emissions reduction calculations.
technology performance evidence.
maintenance records.
integration support for low-carbon production systems.
8. Logistics emissions and transport suppliers
Chemical supply chains are logistics-intensive. Covestro’s Scope 3 reduction depends partly on upstream transportation, logistics routing, storage, marine and road freight, rail and intermodal transport.
Logistics suppliers may need to provide:
transport mode data.
route and distance information.
shipment weights.
fuel consumption.
load factors.
warehouse energy use.
tank container or bulk transport data.
hazardous goods compliance evidence.
emissions factors.
logistics optimization plans.
lower-carbon transport options.
Because Covestro’s Scope 3 target covers upstream transportation among relevant categories, logistics providers become climate data providers, not only freight contractors.
9. Health, safety, environmental and contractor controls
As a major polymer and chemical company, Covestro’s supplier framework also includes high HSE relevance. Suppliers and contractors may operate in production sites, logistics chains, chemical handling, maintenance, engineering and waste operations.
High-impact suppliers include:
raw-material suppliers.
chemical intermediates suppliers.
feedstock suppliers.
site contractors.
maintenance providers.
engineering companies.
waste handlers.
hazardous material logistics providers.
environmental service providers.
recycling partners.
Supplier obligations may include:
HSE management systems.
chemical safety documentation.
hazardous material controls.
waste and wastewater documentation.
air emissions control evidence.
incident reporting.
emergency response capability.
training records.
contractor qualification.
audit participation.
corrective action implementation.
In chemical procurement, HSE performance is inseparable from sustainability. Poor contractor or supplier controls can create safety, environmental, regulatory and reputational risk.
10. Data systems and governance architecture
Covestro’s framework requires suppliers to operate data systems that can support procurement, sustainability assessment, Scope 3 accounting, product carbon footprinting and circularity claims.
Suppliers need systems covering:
Supplier Code compliance.
TfS assessment data.
audit documentation.
emissions and energy accounting.
product carbon footprint calculations.
feedstock origin.
mass-balance and chain-of-custody records.
Renewable Energy Evidence.
logistics emissions data.
HSE records.
corrective action tracking.
customer-specific product data.
The governance challenge is data consistency. Supplier data must be compatible with Covestro’s Scope 3 calculations, customer product carbon needs, circular-economy claims and procurement risk systems. Weak data creates both compliance and commercial risk.
Important Deadlines
Key timelines include:
2021: baseline year for Covestro’s Scope 3 reduction target.
2024: Covestro published Scope 3 climate neutrality targets, including a 30% reduction by 2035 and net zero Scope 3 emissions by 2050.
2035: target to reduce Scope 3 emissions by 10 million metric tons, equivalent to 30% versus 2021.
2035: target for Scope 1 and 2 climate neutrality.
2050: target for net zero Scope 3 emissions across the value chain.
Annual: sustainability reporting and ESRS-aligned sustainability disclosure cycles.
Ongoing: Supplier Code integration into contracts and electronic ordering systems.
Ongoing: supplier assessments, TfS-related assessments and audits.
Ongoing: Supplier Engagement Program discussions with raw-material suppliers and product carbon footprint data collection.
Current Status
The framework is active, mature and becoming more carbon-data-intensive. Covestro has moved beyond generic supplier sustainability expectations toward Scope 3 heatmapping, supplier engagement, product carbon footprint feedback and circular feedstock transformation.
The framework is strongest in:
Supplier Code contractual integration.
supplier assessments and sustainability management.
TfS chemical-sector standardization.
Scope 3 reduction strategy.
product carbon footprint engagement.
circular economy and alternative raw materials.
renewable energy and low-carbon production.
HSE and environmental procurement controls.
Covestro’s Scope 3 target makes supplier performance central to corporate climate governance because upstream and downstream value-chain emissions account for most of the company’s total greenhouse gas footprint.
