Why ESG Ratings Should Be Sector-Specific, Not One-Size-Fits-All
ESG ratings are becoming an important part of how companies are assessed by buyers, investors, lenders, and procurement teams. But one of the biggest weaknesses in ESG evaluation is applying the same assessment lens to every business. A logistics supplier, a plastics manufacturer, a food processing company, and a pharmaceutical distributor do not create the same ESG risks. They do not use the same resources, operate under the same compliance pressures, or influence the supply chain in the same way.
That is why company ESG ratings should be sector-specific. A generic ESG score may provide a surface-level view of sustainability performance, but it can miss the operational realities that actually matter in each industry. Global sustainability frameworks increasingly recognize this need. For example, IFRS S1 requires companies to consider industry-based SASB disclosure topics when identifying sustainability-related risks and opportunities, while GRI Sector Standards are designed to guide organizations on topics likely to be material for their sector.
Why a Generic ESG Rating Can Be Misleading
A one-size-fits-all ESG rating often measures companies against broad themes such as emissions, waste, labour practices, governance, and compliance. These themes are useful, but they do not carry the same weight in every industry.
For example, carbon emissions may be a major risk indicator for a metals producer, while product safety and ethical supply chains may be more critical for a pharmaceutical supplier. A packaging manufacturer may need deeper evaluation around materials, recyclability, and waste management, while a logistics company may need closer assessment of fleet emissions, fuel efficiency, route optimization, and subcontractor controls.
If every company is scored using the same ESG checklist, the rating may reward companies that perform well on easy-to-document areas while underweighting sector-specific risks. This creates a distorted picture. Procurement teams may assume a supplier is low risk when the most material ESG issues in that supplier’s industry were never properly assessed.
Materiality Changes by Sector
Sector-specific ESG assessment is built around the idea of materiality. In simple terms, material ESG issues are the issues most relevant to a company’s impact, risk exposure, financial resilience, and stakeholder expectations.
The SASB Standards group sustainability topics across environment, social capital, human capital, business model and innovation, and leadership and governance, but the specific issues that drive long-term value vary by industry and company. This is exactly why ESG ratings need industry context.
A food manufacturer, for instance, may have material ESG issues related to water use, food safety, packaging waste, energy consumption, supplier traceability, and worker health. A steel or aluminium supplier may need to be assessed more deeply on energy intensity, greenhouse gas emissions, occupational safety, responsible sourcing, and environmental permits. Both companies may receive an ESG rating, but the rating should not be based on identical scoring priorities.
Plastics Suppliers Need a Waste and Circularity Lens
For plastics manufacturers, ESG assessment should go beyond general environmental policies. The rating should examine how the company manages raw materials, production waste, recycled content, hazardous substances, emissions, water use, and end-of-life product considerations.
A plastics supplier may have a strong employee policy and basic governance documentation, but that does not fully answer the ESG question. Buyers increasingly want to know whether the supplier is reducing virgin plastic dependency, improving material recovery, controlling chemical risks, and supporting circular economy goals.
A sector-specific ESG rating for plastics should evaluate:
Waste reduction and recycling practices
Use of recycled or alternative materials
Energy and emissions intensity
Chemical and hazardous material controls
Product design for recyclability
Supplier and customer documentation on sustainability claims
Without this lens, ESG ratings risk treating plastics suppliers the same as low-impact service providers, even though their environmental footprint and buyer expectations are very different.
Metals, Aluminium, and Steel Require an Energy and Emissions Lens
Metals, aluminium, and steel suppliers often operate in energy-intensive environments. Their ESG rating should place greater emphasis on emissions management, energy sourcing, production efficiency, worker safety, environmental compliance, and responsible sourcing of inputs.
For these companies, a generic ESG assessment may not be enough. A supplier may have good governance policies, but if it has limited data on energy intensity, emissions reduction, or workplace safety, procurement teams still face material risk.
A strong sector-specific ESG rating for metals suppliers should assess:
Energy consumption per production unit
Carbon reduction plans
Renewable energy adoption
Occupational health and safety performance
Environmental permits and compliance history
Responsible sourcing of raw materials
Waste, scrap, and by-product management
This matters because industrial buyers often need supplier-level ESG data for their own Scope 3 emissions, responsible sourcing commitments, and supply-chain risk reporting.
Food Manufacturing Needs a Safety, Water, and Traceability Lens
Food manufacturing companies face a different ESG risk profile. Their sustainability performance is not only about emissions or waste. It is also linked to food safety, water usage, packaging, labour standards, hygiene systems, sourcing practices, and traceability.
A food supplier with poor traceability can create reputational and operational risk for buyers. A manufacturer with weak water management may face future production risk. A company with poor packaging practices may affect the sustainability goals of retailers, hotels, distributors, and FMCG buyers.
A sector-specific ESG rating for food manufacturing should consider:
Water consumption and wastewater management
Food safety and quality systems
Packaging sustainability
Energy use in production and cold storage
Ingredient sourcing and traceability
Waste reduction, including food waste
Labour practices and worker welfare
This gives buyers a more realistic view of whether the supplier can meet sustainability, quality, and operational expectations.
Pharmaceutical Suppliers Need a Governance and Compliance Lens
For pharmaceutical and medical product suppliers, ESG rating must give heavier weight to governance, compliance, product safety, ethical conduct, waste handling, and supply-chain integrity.
Pharma suppliers may not always have the highest visible emissions compared to heavy manufacturing, but their ESG risks can be serious. Poor governance, weak quality controls, unethical sales practices, unsafe waste disposal, or lack of traceability can create major business and compliance exposure.
A sector-specific ESG rating for pharmaceutical suppliers should evaluate:
Regulatory compliance systems
Product safety and quality controls
Ethical marketing and anti-bribery policies
Waste disposal, including hazardous and medical waste
Supply-chain traceability
Employee safety and training
Data integrity and documentation practices
In this sector, governance is not just a corporate formality. It directly affects trust, market access, and buyer confidence.
Logistics Suppliers Need a Fleet, Fuel, and Subcontractor Lens
Logistics companies have a different ESG profile from manufacturers. Their material issues often relate to fuel consumption, vehicle emissions, driver safety, route efficiency, warehousing energy use, subcontractor governance, and labour practices.
A logistics supplier may appear ESG-ready based on office policies and general compliance documents, but the real sustainability risk may sit in fleet operations and third-party transport partners.
A sector-specific ESG rating for logistics suppliers should assess:
Fleet emissions and fuel efficiency
Route optimization practices
Use of low-emission vehicles
Driver safety and working conditions
Warehousing energy management
Subcontractor ESG controls
Delivery performance and operational resilience
For companies that depend on logistics partners, this type of ESG assessment helps identify risk across the movement of goods, not just within direct manufacturing operations.
Sector-Specific Ratings Improve Procurement Decisions
Procurement teams increasingly need ESG data that is practical, comparable, and relevant. A sector-specific ESG rating allows buyers to compare suppliers within the same industry using meaningful criteria.
This helps procurement teams answer important questions:
Can this supplier support our sustainability commitments?
Does the supplier create hidden environmental or social risk?
Is the company collecting the right ESG data for its industry?
Can it provide documentation for audits, reporting, or customer requirements?
Is the supplier improving over time or only completing minimum paperwork?
A generic score may tell procurement teams that a supplier is “medium risk” or “low risk.” A sector-specific rating explains why. That difference is important for supplier selection, contract renewal, corrective action planning, and long-term vendor development.
Conclusion
Company ESG ratings should not treat every business as if it creates the same risks. Plastics, metals, food manufacturing, pharmaceuticals, packaging, and logistics suppliers each have different sustainability impacts, operational pressures, and buyer expectations. A one-size-fits-all rating may be simple, but it is not always useful.
For ESG ratings to support better procurement, supplier risk management, and sustainability improvement, they must be sector-specific, evidence-based, and connected to the realities of each industry.
For UAE businesses and suppliers, this approach is becoming increasingly important as buyers, investors, and supply-chain partners expect clearer ESG data and more credible sustainability performance. Platforms such as Synesgy can help companies assess ESG performance through structured ratings, identify sector-relevant gaps, and build stronger sustainability readiness for today’s procurement and supply-chain environment.
