A green supply chain can give a company a competitive advantage when environmental improvements also create measurable business value—such as using fewer resources, reducing waste, meeting customer or market requirements, or improving resilience. The evidence points to positive average relationships with performance, not a guaranteed profit increase: results differ by practice, company, and measurement method.
What counts as a green supply chain?
Green supply-chain management (GSCM) brings environmental considerations into a company’s operations and its relationships with suppliers and customers. It can cover the full flow of products and materials, from design and sourcing through production, distribution, reuse, and disposal. The studies discussed here examine practices including internal environmental management, sustainable sourcing or green purchasing, eco-design, customer collaboration, reverse logistics, investment recovery, and environmental management system certification. Definitions and measurements vary across studies, so “green supply chain” does not refer to one standardized package of practices.
A green supply chain is therefore more than a sustainability label or a single certification. Its competitive relevance depends on which impacts a business addresses and whether the changes matter to its costs, customers, operations, or access to markets.
Does a green supply chain give a company a competitive advantage?
On average, research finds positive associations between GSCM and performance, but the findings do not prove that adopting these practices alone causes higher profits. In a 2023 meta-analysis, Heinz Holling and Leonie Backhaus combined 408 correlations from 134 studies and reported a mean relationship of r = 0.442 between GSCM practices and firm performance. That figure is an association across studies, not an estimate of return on investment for a company adopting a program. Read the 2023 meta-analysis.

#1 Best Overall
A 2024 meta-analysis by Igor Galdos-Urbizu, Amaia Heras-Saizarbitoria, and Iñaki Boiral examined 166 empirical studies and 335 samples. It reported an overall correlation of r = 0.3984 between GSCM practices and corporate environmental performance (95% confidence interval: 0.375–0.421). The authors found substantial variation among studies, which means the average does not predict what a particular company will achieve. Read the 2024 meta-analysis.
Those results are consistent with a business case, but they should not be read as proof of a universal financial payoff. Environmental outcomes, operational performance, and financial returns are related but distinct measures. A company needs to track each one rather than assume that an environmental improvement automatically becomes a cost saving or revenue gain.
How can a green supply chain create business value?
The routes from environmental practice to competitive advantage are practical possibilities, not guaranteed outcomes. A company can assess whether a particular practice is likely to create value in its own supply chain.
- Resource and waste efficiency: Using less material, energy, or packaging—or recovering value from surplus and discarded materials—may lower operating costs when the savings exceed implementation and coordination costs.
- Product differentiation: Eco-design or credible environmental performance may help a company meet customer preferences or distinguish its offer. The benefit depends on whether buyers value the difference and can verify it.
- Customer and market access: Environmental requirements set by customers or markets can make supply-chain changes necessary to compete for business. Meeting a requirement protects or opens an opportunity; it does not by itself guarantee sales.
- Supply continuity and risk management: Working with suppliers to understand environmental impacts and constraints may help a company identify vulnerabilities. The practical advantage depends on whether the work leads to effective risk reduction.
- Distribution performance: An archived Canadian government report summary describes lower distribution costs, differentiation, risk management, increased sales, and foreign-market access as potential benefits of distribution-focused GSCM. Its publication date was not established, so these should be treated as reported possibilities rather than current, market-wide results. Read the Canadian report summary.
Which green supply-chain practices have stronger evidence?
The 2024 meta-analysis found positive average associations between several practices and corporate environmental performance, but the association sizes differ. They are not rankings of financial returns or proof that one intervention will outperform another at a particular company.
| Practice | Association with corporate environmental performance | What the comparison means |
|---|---|---|
| Investment recovery | r = 0.4717 | Strongest association among the listed practices in this analysis; not an investment-return estimate. |
| Eco-design | r = 0.4562 | Associated with environmental performance; potential relevance depends on how design affects materials, use, and end-of-life handling. |
| Sustainable sourcing | r = 0.3974 | Associated with environmental performance; supplier impacts and requirements may affect its relevance. |
| Customer collaboration | r = 0.3860 | Associated with environmental performance; collaboration may matter where customer requirements shape products or operations. |
| Environmental management system certification | r = 0.2699 | Positive association in the analysis; certification alone should not be assumed to create a competitive advantage. |
| Reverse logistics | r = 0.2063 | Positive association in the analysis; the result does not establish that reverse logistics is ineffective for an individual firm. |
The same analysis reported a stronger association for internal practices (r = 0.4704) than for external practices (r = 0.3649), with a statistically significant difference between the categories. These results point to the importance of practice choice, but a lower average association does not mean a practice is unhelpful in a specific supply chain. See the authors’ practice-level analysis.
How should practice choice fit competitive strategy?
Cost leadership and differentiation can call for different GSCM priorities. A 2022 study of manufacturing companies in Jordan, based on 142 survey responses, found that cost leaders paid limited attention to GSCM and focused on investment recovery. Differentiators adopted a broader mix, including internal environmental management, green purchasing, customer collaboration, and eco-design. In that sample, only internal environmental management and investment recovery were positively related to financial performance. The findings describe one country and manufacturing context, not a universal formula for either strategy. Read the Jordan manufacturing study.
Rank #4
For a cost-focused company, a practice is commercially relevant when it can address material waste, resource use, or another operational cost without undermining service or quality. For a differentiator, the case may depend more on whether product or process improvements are valued by customers and can be substantiated. These are decision principles for evaluating fit, not outcomes established for every industry.
Broader context also matters. A 2017 meta-analysis of Asian emerging-economy evidence covered 50 articles, 11,127 manufacturing companies, and 130 effects. It reported positive links with economic, environmental, operational, and social performance, while findings varied by industry, firm size, ISO certification, and export orientation. Read the Asian emerging-economy meta-analysis.
Why do company size and measurement affect the results?
The 2024 meta-analysis reported a stronger association between GSCM practices and corporate environmental performance for large firms (r = 0.4039) than for small and medium-sized firms (r = 0.3219). It also found that results varied with a country’s environmental-awareness index and with whether corporate environmental performance was self-disclosed or externally rated. Self-disclosed performance showed a larger association than external ratings, so company-reported improvements merit particular care when comparing claims.
These differences do not establish that small firms cannot benefit. They show why an average from multiple studies is not a reliable forecast for a company with a different size, supply-chain position, industry, geography, or measurement approach.
How should a company evaluate the business case?
There is no single implementation sequence established by the studies reviewed here. A company can make its own evaluation more useful by linking chosen practices to a defined baseline and tracking environmental, operational, and financial outcomes separately.
- Identify the material supply-chain issue. Determine whether the priority lies in product design, purchased inputs, internal operations, distribution, customer requirements, or reverse flows.
- Choose a practice tied to the issue and strategy. For example, eco-design may be relevant when design determines material use or end-of-life recovery; supplier collaboration may be relevant when upstream impacts or buyer requirements dominate.
- Set a baseline and comparable indicators. Record the starting environmental and operational measures, then define how and when they will be measured again.
- Track business consequences alongside environmental outcomes. Measure actual costs, service effects, and revenue results where relevant; do not treat an environmental metric as a substitute for a financial result.
- Make the measurement source clear. Distinguish company-reported figures from independent assessment so that decision-makers can judge how claims were verified.
This approach is a prudent way to test fit and value; it is not a protocol proven to work universally. The 2018 systematic review and meta-analysis also reflects the wider challenge of comparing GSCM performance across studies using different definitions and measures.
