Sustainable Supply Chain Management

For most companies today, sustainable supply chain management isn’t optional anymore—it’s the price of doing business with larger customers. If you’re an SME embedded in a bigger organization’s supply network, you’ve probably noticed the shift: procurement teams now want policies, metrics, and evidence, not just competitive pricing. And now that the global supply chain is shifting and mired in uncertainty, it has forced many businesses to enter new markets, with new regulations. This has created a race to update many practices and policies to remain competitive. Like it or not, no matter which country you operating out of, there is a Supplier Assurance Questionnaire looming in your future.

But don’t panic yet, because this guide walks you through what sustainable supply chain management actually means. What it means in practice and why it matters for your business. It also covers how to build a defensible ESG baseline that satisfies customer questionnaires and audits without overwhelming your team.

Key Takeaways

• Sustainable supply chain management integrates environmental, social, and financial goals into sourcing, production, logistics, and end-of-life decisions—treating sustainability as a core business function rather than an add-on project.
• For most companies, 70–90% of total greenhouse gas emissions and a significant share of social risks sit in the supply chain (Scope 3 Category 1 & 4), making supply chain sustainability central to credible ESG performance.
• SMEs in larger supply chains increasingly face detailed ESG questionnaires, audits, and contract clauses aligned to frameworks like GRI, ISSB, and EU CSRD/ESRS—practical documentation is now a competitive necessity.
• You don’t need enterprise-scale systems to start: structured policies, basic metrics, and reusable templates can position your company to respond confidently to buyer demands within days.
• ESG | The Report provides practical toolkits and advisory support designed specifically to help SMEs build supply chain readiness without large consulting budgets or dedicated sustainability teams.

What Is Sustainable Supply Chain Management (SSCM)?

Sustainable supply chain management is traditional supply chain management expanded to include explicit environmental, social, and governance objectives across all stages—from raw materials at Tier 3 suppliers through to end-of-life disposal and recycling.

Where conventional supply chain operations focus primarily on cost, speed, and reliability, SSCM adds a second layer of consideration: How do these operations affect the planet, workers, and communities? And how can we document and improve that impact over time?

The shift is from linear “take-make-waste” models to circular, low-carbon, and ethical processes. Think closed-loop packaging that returns to suppliers for reuse, remanufacturing of components that would otherwise become waste, or route optimization that cuts both fuel consumption and carbon emissions simultaneously.

You’ll encounter several related terms in this space:

• Sustainable supply chain typically refers to the overall system designed with sustainability embedded throughout
• Green supply chain emphasizes environmental aspects like energy usage, emissions reduction, and waste minimization
• Responsible supply chain and ethical supply chain highlight human rights, fair labor practices, and governance
• Sustainable sourcing focuses specifically on procuring sustainable materials from suppliers who meet environmental and social standards

This article uses SSCM as the umbrella term because it captures all three dimensions—environmental, social, and financial—that buyers now evaluate in their suppliers.

At ESG | The Report, we use SSCM as a core lens when building ESG baselines, supplier responses, and policy bundles for SMEs. The goal is always practical: documentation that stands up to scrutiny and can be reused across multiple customer requests.

Why Sustainability Matters in the Supply Chain

Multiple studies between 2018–2024 have established a stark reality: supply chains typically account for more than 90% of a consumer company’s greenhouse gas emissions and a majority of human-rights risks. Research from CDP and McKinsey consistently shows that upstream and downstream activities—purchased goods, transportation, product use, and end-of-life treatment—dwarf the environmental impact of a company’s direct operations.

This is precisely why large companies have shifted their attention from their own factories and offices to their entire supply network. When a retailer commits to net-zero by 2050, they can’t get there without changing how their suppliers operate.

The External Pressure Wave Since 2020

The regulatory and buyer landscape has fundamentally changed in recent years, especially with the global supply chain uncertainty with recent changes in the White House in 2026:

Post-COVID supply chain disruptions exposed vulnerabilities in global supply chains, prompting companies to demand better supply chain visibility and resilience from their suppliers.

The EU Green Deal and Corporate Sustainability Reporting Directive (CSRD) now require thousands of European companies to report on supply chain sustainability initiatives—and they’re cascading those requirements down to their suppliers.

Germany’s Supply Chain Due Diligence Act (LkSG, 2023) makes large German companies legally responsible for human rights and environmental due diligence throughout their supply chains.

The EU Corporate Sustainability Due Diligence Directive (CSDDD) will extend similar requirements across the EU, creating increasing pressure on suppliers of all sizes.

Large buyers now expect their suppliers to provide data on carbon emissions, worker safety, and raw material sourcing—often aligned with GRI, SASB/ISSB, or sector-specific standards. Lack of evidence can block tenders or trigger audit findings.

Real Business Risks for SMEs

If you’re an SME, these aren’t abstract policy discussions. The concrete risks include:

• Losing key contracts when you can’t answer ESG questionnaires satisfactorily
• Failing pre-qualification rounds for tenders that score sustainability
• Reputational damage from a supplier incident that traces back to your operations
• Disruptions from environmental events (floods, heatwaves, resource shortages) that affect your own suppliers

But there’s an opportunity side too. Companies that document their sustainability efforts often gain preferred supplier status, better financing terms from banks that factor ESG into credit decisions, and long-term cost savings from operational efficiency improvements and waste reduction. To learn more about the benefits of ESG for companies, see this resource.

Core Dimensions of Sustainable Supply Chain Management

The “triple bottom line” structure—environmental, social, and financial—offers a clear way to organize SSCM expectations for SMEs serving larger customers. Each dimension should translate into specific supplier requirements, metrics, and contract clauses, not just broad commitments on a website.

Environmental Responsibility in the Supply Chain

Environmental responsibility means reducing greenhouse gas emissions, pollution, and resource use across sourcing, production, transport, warehousing, and end-of-life.

Key focus areas include:

• Energy efficiency in operations and facilities
• Renewable energy adoption where feasible
• Fuel-efficient or multimodal transport options
• Packaging reduction and sustainable packaging materials
• Water management and conservation
• Waste minimization, recycling, and avoiding excess waste

For emissions tracking, the Scope 3 categories most relevant to supply chains are:

• Category 1: Purchased goods and services
• Category 4: Upstream transportation and distribution
• Category 9: Downstream transportation and distribution
• Category 12: End-of-life treatment of sold products

Practical examples:

• Using recycled input materials that reduce resource usage and raw materials extraction
• Implementing reusable pallets and containers that cut packaging waste
• Redesigning delivery routes to eliminate empty miles and reduce carbon footprint
• Installing energy-efficient lighting and equipment that cuts energy consumption

Larger buyers often request environmental data aligned with frameworks like GRI 302 (Energy), GRI 303 (Water), GRI 305 (Emissions), or the EU ESRS E1 and E2 standards. Even if you’re not directly reporting under these frameworks, you should be ready to provide at least basic numbers and policies.

Social Responsibility and Human Rights

Social responsibility in SSCM means ensuring fair wages, safe working conditions, non-discrimination, and respect for human rights throughout the entire supplier network—including Tier 2 and Tier 3 suppliers you may not deal with directly.

The concrete instruments that shape expectations include:

• ILO core conventions on forced labor, child labor, discrimination, and freedom of association
• UN Guiding Principles on Business and Human Rights (2011)
• National laws like Germany’s LkSG (2023) and France’s Duty of Vigilance Law (2017)

What buyers typically expect:

• A written Code of Conduct for suppliers
• Documented grievance mechanisms for workers to report concerns
• Incident logs and response procedures
• Periodic supplier assessments or audits

High-risk areas that often receive extra scrutiny include mining of cobalt or mica, agricultural seasonal labor, and textiles and electronics assembly—sectors where ethical labor practices and social sustainability concerns are well-documented. This is why supply chain transparency beyond direct Tier 1 suppliers matters.

ESG | The Report’s Core Policy Bundle and Supply Chain Audit Toolkit provide templates for human-rights policies, supplier codes, and audit checklists that SMEs can adapt quickly to their own operations.

Financial and Operational Responsibility

SSCM must also support financial resilience—reducing cost and volatility, strengthening continuity, and maintaining regulatory compliance to avoid fines and contract penalties. Sustainability strategies that hurt the bottom line aren’t sustainable at all.

Where sustainability and financial performance align:

• Better demand forecasting and inventory management cut both costs and emissions (fewer rush air shipments, lower safety stock holding costs)
• Route optimization reduces fuel consumption and delivery expenses simultaneously
• Energy efficiency projects typically pay back within 1–3 years while reducing your ecological footprint
• Material yield improvements and reduced scrap improve margins while minimizing waste

Digital tools like basic ERP systems, transportation management software, and simple carbon calculators can help SMEs identify high-cost, high-emission activities and prioritize improvements without major capital investment.

Lenders and investors increasingly look at supply-chain-related ESG risks when assessing credit terms, especially in export-heavy sectors. Documenting your sustainable operations can support lower insurance premiums and better financing conditions.

How Sustainable Supply Chains Work in Practice

Consider a mid-sized manufacturer sourcing metal components in 2024. In a traditional model, procurement focuses on price, quality, and delivery time. A more sustainable supply chain changes decisions at each step:

Sourcing: The manufacturer requests data from first tier suppliers on energy sources, certifications, and worker safety records. They map where raw material sourcing originates and identify country-level risks.

Production: Operations tracks energy usage, waste volumes, and incident rates. They document process improvements and set targets for reducing waste and reducing carbon emissions.

Transport: Logistics evaluates carrier options based on emissions intensity alongside cost. They consolidate shipments and optimize routes to cut both expenses and carbon footprint.

Customer delivery: The manufacturer can provide evidence of environmental sustainability and social sustainability practices when customers request it—in questionnaires, audits, or contract negotiations.

The key characteristics of sustainable supply chains are:

• Collaboration: Working with supply chain partners rather than just policing them
• Transparency: End-to-end supply chain visibility into where materials come from and how they’re processed
• Data-driven decisions: Using metrics and evidence rather than assumptions
• Aligned incentives: Contracts, supplier scorecards, and shared targets (like joint emission reduction goals by 2030) that make sustainability everyone’s responsibility

SMEs don’t need enterprise systems to start. Structured spreadsheets, standard questionnaires, and policy templates can align you with larger customer expectations. The goal is building a transparent supply chain with documented practices, not implementing complex technology.

Technology and Data in Sustainable Supply Chain Management

Modern SSCM relies heavily on data collection, integration, and analysis. But SMEs should focus on “right-sized” tools rather than enterprise-scale platforms that exceed their actual needs.

Digital technologies help in several ways:

• Cloud ERP systems centralize operational data
• Basic carbon accounting tools estimate emissions from purchases and transport
• Supplier portals collect and store ESG information from your supply network
• Document management systems ensure policies and evidence are audit-ready

You’ll hear about advanced technologies like artificial intelligence, machine learning, blockchain, RFID, and IIoT. Here’s when they actually matter for SMEs:

Technology	When It Matters	When Spreadsheets Are Sufficient
AI/Machine Learning	High-volume demand forecasting, complex pattern detection	Basic trend analysis, simple metrics tracking
Blockchain	High-value traceability requirements, regulated commodities	Standard supplier certifications and documentation
RFID/Track-and-trace	Real-time inventory in complex operations	Periodic inventory counts, standard shipping documentation

For most SMEs, the priority is structured, consistent data that can be provided to larger customers on request—not cutting-edge technology.

Visibility, Traceability, and Supplier Data

Visibility means knowing where products and materials are at any given time. Traceability means knowing their origin and processing history. Both are essential for audits and ESG reports.

Basic approaches SMEs can use right now:

• Standardized supplier questionnaires covering key ESG attributes
• Document repositories storing certifications, permits, and audit reports
• Simple databases or spreadsheets capturing supplier locations, main inputs, energy sources, and high-risk materials

Key data fields to track:

• Supplier name, location, and contact
• Main inputs and materials supplied
• Energy sources used in production
• Relevant certifications (ISO 14001, ISO 45001, FSC, etc.)
• Known ESG risks or concerns
• Date of last assessment or audit

Larger organizations may use blockchain and track-and-trace platforms, but suppliers still need to provide accurate, timely data—often via online portals. ESG | The Report’s Supply Chain Audit Toolkit can structure this data collection for audits and customer questionnaires, making traceability manageable for smaller firms.

Tools for Measuring Environmental and Social Impact

Carbon calculators and life-cycle thinking help estimate indirect emissions from purchased goods, transport, and waste—even when precise primary data isn’t available from suppliers.

SMEs can start with simple intensity metrics:

• kg CO₂e per unit produced
• Incident rates per 100 employees
• Percentage of spend with certified suppliers
• Waste diverted from landfill as percentage of total waste
• Energy intensity per revenue or production unit

The frameworks that influence buyer requests include:

• GHG Protocol for Scope 1, 2, and 3 emissions calculation
• GRI Standards for sustainability disclosures
• ISSB Standards (formerly SASB) for industry-specific metrics
• EU ESRS for companies subject to CSRD
• Carbon Disclosure Project supply chain program

These cascade down to SMEs through customer questionnaires and contract requirements. ESG | The Report provides templates and guidance for building a defensible ESG baseline, including basic metrics and documentation that can be reused across multiple customer requests.

Regulation, Standards, and Buyer Expectations

Since around 2021, there’s been a rapid increase in regulations and standards that indirectly affect SMEs through supply-chain requirements—even if the SMEs themselves aren’t directly regulated.

Major frameworks shaping expectations:

• UN Global Compact: The 10 principles which cover human rights, labor, environment, and anti-corruption
• OECD Due Diligence Guidance: Practical recommendations for responsible business conduct in global supply chains
• UN Guiding Principles on Business and Human Rights: The foundational framework for corporate human rights responsibility

Key regulatory drivers:

Regulation	Scope	Impact on Suppliers
EU CSRD/ESRS (2024+)	Large EU companies and their value chains	Suppliers must provide data on emissions, human rights, and governance
German LkSG (2023)	Large German companies	Must conduct due diligence on Tier 1 and critical Tier 2 suppliers
EU CSDDD (coming)	Large EU companies	Will extend due diligence requirements across the supply chain

Large customers translate these rules into practical demands: ESG questionnaires in procurement, contract clauses on codes of conduct, and requirements for evidence like policies, risk assessments, and improvement plans.

The efficient response for SMEs is building a reusable ESG documentation set—policies, metrics, and processes—rather than starting from scratch for every new buyer request.

ESG Frameworks Relevant to Supply Chains

Several frameworks appear regularly in supply-chain questionnaires:

GRI Standards: The most widely used sustainability reporting framework globally. Even if you’re not publishing a GRI report, buyers may ask for information organized by GRI topic numbers.

ISSB Standards (formerly SASB): Industry-specific metrics that investors and large buyers use to compare companies. Focus on financially material sustainability topics.

CDP Supply Chain Program: Large buyers request that suppliers disclose environmental data through CDP. Increasingly covers climate, water, and forests.

Science Based Targets initiative (SBTi): Companies with net-zero commitments often expect suppliers to set their own science-based targets for reducing emissions aligned with the organization’s climate pledges.

Even if you’re not formally reporting under these frameworks, familiarizing yourself with basic terminology and topic structures helps you interpret and respond to customer questionnaires more confidently.

ESG | The Report’s ESG Reporting Toolkit translates these high-level frameworks into concrete templates and responses that SMEs can adapt to their own business operations.

Implementing Sustainable Supply Chain Management: A Practical Roadmap for SMEs

This roadmap is specifically tailored to small and medium-sized businesses that supply larger organizations. The focus is on what can realistically be done in 6–18 months with limited resources.

The core principle is reuse: one set of policies, metrics, and processes serving multiple buyers, certifications, and audits. Build once, deploy many times.

Step 1: Map Your Supply Chain and ESG Exposure

Start by identifying your direct suppliers (Tier 1), main materials, and major logistics routes. Then assess where environmental and human impact risks are likely concentrated.

A simple mapping approach:

1. List your top 10-20 suppliers by spend
2. Document what each supplies (materials, components, services)
3. Note the country of origin for key inputs
4. Assign a rough risk level (high/medium/low) based on:

5. Country risk (governance, labor standards, environmental regulation)

6. Material type (minerals, agricultural products, chemicals)

7. Spend importance (what would disrupt your operations if unavailable)

8. Country risk (governance, labor standards, environmental regulation)
9. Material type (minerals, agricultural products, chemicals)
10. Spend importance (what would disrupt your operations if unavailable)

Example mapping:

• Metal parts from suppliers in Southeast Asia → Medium-high risk (labor practices, limited visibility beyond Tier 1)
• Packaging from regional suppliers → Lower risk (closer monitoring, familiar regulatory environment)
• Logistics providers → Focus on emissions data and route efficiency

This mapping is often the first thing requested in buyer due-diligence questionnaires. ESG | The Report’s Supply Chain Audit Toolkit provides checklists and templates for this exercise.

Step 2: Establish Core Policies and Supplier Expectations

Buyers increasingly expect written, board-approved policies covering:

• Environmental management and emissions
• Health and safety
• Human rights and labor standards
• Anti-corruption and business ethics
• Supplier Code of Conduct

Policies should be short, specific, and clearly communicated to suppliers—included in contracts or onboarding packs, not generic statements buried on your website.

Prioritize 3-5 core policies first:

1. Environmental Policy (covering energy, waste, emissions)
2. Health and Safety Policy
3. Human Rights/Labor Standards Policy
4. Supplier Code of Conduct
5. Anti-Corruption Policy

ESG | The Report’s Core Policy Bundle and Supplier Code templates offer fast-track options for SMEs that lack in-house legal or ESG teams. Include version control and review dates (e.g., annual review in Q4) so policies look credible in audits.

Step 3: Collect and Organize Key ESG Data

Start with a focused set of metrics that you can track consistently:

Category	Starter Metrics
Energy	Total electricity and fuel use (kWh, liters)
Emissions	Scope 1 and 2 estimates (tCO₂e)
Waste	Total waste volume, recycling rate
Safety	Incidents, near-misses, lost-time injury rate
Workforce	Headcount, turnover, training hours
Suppliers	Key certifications, audit outcomes, high-risk supplier count

Data can initially be rough but must be traceable—tied back to invoices, utility bills, or HR records—and consistent year-to-year.

Build a simple, reusable ESG data file that can be quickly updated for tenders, supplier scorecards, or platform uploads (EcoVadis, CDP supply chain portals, customer-specific systems).

ESG | The Report’s ESG Reporting Toolkit provides structure for this, with ready-made spreadsheets and guidance on the minimum credible data set.

Step 4: Engage Suppliers and Set Improvement Priorities

Roll out expectations to key suppliers with practical tools:

• Short questionnaires covering essential ESG topics
• Self-assessment forms suppliers can complete independently
• Basic contract clauses referencing your Supplier Code of Conduct

Focus first on high-risk or high-spend suppliers. Request specific evidence:

• Safety training records
• Environmental permits and licenses
• Social certifications (ISO 45001, SA8000 where relevant)
• Recent audit reports

Start with a small pilot group of suppliers and a short questionnaire. Refine based on responses before expanding.

Regular, honest dialogue often works better than one-off compliance emails—especially where suppliers have limited resources themselves. Frame this as collaborative improvement through better supply chain management, not just policing.

Step 5: Integrate SSCM into Procurement and Operations

Procurement decisions can incorporate ESG criteria alongside price and quality. This doesn’t mean ignoring costs—it means understanding total value including sustainability factors.

Practical integration steps:

• Include ESG requirements in RFQs and tender documents
• Add sustainability questions to supplier onboarding
• Use dual-sourcing to reduce disruption risk from extreme weather
• Prefer suppliers with lower emissions, stronger safety records, or local sourcing that reduces transport impacts

Operational changes with quick impact:

• Route consolidation that cuts fuel and delivery costs
• Optimized packaging that reduces material use and shipping weight
• Maintenance programs that cut energy use and extend equipment life
• Preventive safety measures that reduce incidents and insurance costs

Document these changes in policies, SOPs, or process notes so improvements can be demonstrated during audits or customer reviews. This supports supply chain resilience while building evidence for sustainability efforts.

Step 6: Monitor, Report, and Communicate Progress

SSCM is an ongoing process. Establish a basic annual cycle: measure, review, improve, communicate.

Create a simple annual sustainability summary including:

• Key supply-chain metrics and year-over-year trends
• Actions taken during the period
• Challenges encountered and how they were addressed
• Priorities and targets for the coming year

Share this summary with major customers and use it in tender applications. Transparency about gaps and plans—such as committing to map Tier 2 suppliers by 2026 or set Scope 3 estimates by 2027—is often valued more than claiming perfection.

This isn’t about producing glossy sustainability reports. A straightforward 3-5 page summary with clear data and honest assessment meets stakeholders demands without overwhelming small teams.

ESG | The Report offers advisory support and templates to help SMEs package their SSCM story for buyers, investors, and banks.

Benefits and Challenges of Sustainable Supply Chain Management

SSCM offers clear strategic benefits, but small and mid-sized businesses face real constraints in time, budget, and expertise. A realistic view of both sides helps you plan effectively.

Key Business Benefits

Improved risk management and business continuity: Climate-related disruptions like floods, heatwaves, and port closures have increased significantly between 2020–2024. Companies with better supply chain visibility and diversified supplier relationships recover faster.

Revenue protection and growth: Meeting supplier qualification criteria keeps existing business. Winning tenders that score ESG can open new revenue streams. Becoming a preferred vendor for large customers with 2030 or 2050 net-zero targets positions you for long-term relationships.

Cost and efficiency gains: A mid-sized manufacturer implementing energy efficiency measures and route optimization typically sees 5-15% reductions in energy costs within two years. Material yield improvements that reduce scrap by even 2-3% can meaningfully improve margins.

Reputation and stakeholder relationships: Clear ESG documentation supports better brand reputation with regulators, banks, and employees. Some manufacturers have secured lower insurance premiums or better financing terms by demonstrating documented risk management practices.

Example: A European components manufacturer implemented basic SSCM practices over 18 months—policy documentation, supplier questionnaires, energy tracking, and an annual ESG summary. They retained a major automotive customer requiring CSRD-aligned data, won a new contract partly on their sustainability evidence, and identified €40,000 in annual energy savings through the tracking process.

Common Challenges and How to Overcome Them

Challenge	Practical Response
Limited budget	Start with high-impact areas; focus on documentation that multiple stakeholders can use
Fragmented data systems	Use structured spreadsheets before investing in specialized software
Weak leverage over upstream suppliers	Focus on transparency first—ask for information and document responses
Internal skepticism	Align initiatives with clear business goals (cost reduction, contract retention, risk management)
“Moving target” requirements	Build flexible processes rather than one-off checklists; review regulatory updates every 6-12 months

Working with practical toolkits and light-touch advisory—such as ESG | The Report’s resources and consultations—can be more cost-effective than large consulting projects. The goal is progress, not perfection.

FAQ: Sustainable Supply Chain Management

What is the first SSCM action a small supplier should take if a big customer suddenly sends an ESG questionnaire?

Start by mapping which questions relate directly to existing data—energy bills, safety incident records, supplier certifications—and which require new information or policies. Convene a quick internal meeting with operations, HR, and finance to gather available data and identify gaps. For questions you can’t fully answer yet, draft short, honest explanations with realistic timelines for when information will be available. Using a structured template, such as those from ESG | The Report, helps ensure your answers are consistent and can be reused for future questionnaires from other customers.

Do SMEs really need complex software to manage sustainable supply chains?

Most SMEs can begin with spreadsheets, clear policies, and simple data-collection forms. Specialized software only becomes necessary when data volume and complexity justify the investment. What customers and auditors typically look for first is coherence and traceability in documentation, not a specific brand of ESG or supply chain software. Start with structured, consistent processes and introduce digital solutions gradually as your SSCM program matures and your budget allows.

How often should supply chain sustainability risks be reviewed?

At minimum, conduct a formal annual review of supply-chain ESG risks. More frequent check-ins—quarterly, for example—are appropriate for high-risk suppliers or regions with elevated concerns. Reviews should also be triggered by significant events: regulatory changes, major incidents, new sourcing countries, or changes in key supplier relationships. Having a simple, documented review schedule is itself valuable evidence in audits and customer due-diligence assessments.

What if we have very little leverage over our upstream suppliers?

Focus first on transparency rather than immediate change. Ask for information, share your own policies and expectations, and document supplier responses—even if you can’t demand immediate improvements. Aggregating information across your supplier base can help identify alternatives or reveal opportunities for collaborative improvement over time. When you communicate with large customers, being honest about your constraints and gradual improvement plans is generally better received than remaining silent or making unsupported claims about your supply chain.

Can SSCM work without formal certifications like ISO 14001 or ISO 45001?

Certifications can be helpful and are valued by many buyers, but they’re not mandatory for implementing sustainable practices. Many customers will accept well-structured internal policies, documented procedures, and traceable records as evidence of control. You can adopt the core practices behind certifications—plan-do-check-act cycles, documented risk assessments, management review processes—before or instead of pursuing formal certification. Toolkits from ESG | The Report can help approximate these structures in a practical, low-bureaucracy way that suits smaller organizations while still meeting stakeholders demands for evidence-based sustainability.
