Green Supply Chain Management Practices for Carbon Emission Reduction in Manufacturing SMEs Through Sequential Environmental Capability Development
Drawing on the Natural Resource-Based View and survey data from 343 Chinese manufacturing SMEs, this study reveals that Green Supply Chain Management practices drive carbon emission reduction through a sequential capability-building process involving circular economy practices, green innovation, and environmental management practices, a relationship further strengthened by top management's environmental commitment.

The air we breathe and the climate that sustains life are under pressure from the smoke and fumes released by factories. For decades, the industrial world has operated on a simple, linear logic: take raw materials, make products, and discard the waste. This approach has fueled economic growth but has also poured vast amounts of carbon dioxide into the atmosphere, driving global warming. In response, governments and consumers are demanding a shift. They want companies to stop just making things and start managing the entire journey of a product, from the moment raw materials are bought to the moment the product is recycled or thrown away. This holistic approach is known as green supply chain management. It involves buying cleaner materials, manufacturing with less waste, and shipping goods in ways that burn less fuel.
However, a gap has emerged between the desire to be green and the ability to actually reduce emissions. Many small and medium-sized factories, which form the backbone of global manufacturing, have adopted these green supply chain rules. They buy eco-friendly materials and optimize their shipping routes. Yet, despite these efforts, their carbon emissions often remain stubbornly high. The missing link appears to be internal. Having the right external rules is not enough; a factory must also build the internal muscle to turn those rules into real environmental results. Researchers have long suspected that a specific sequence of internal changes is required to bridge this gap, but the exact path has remained unclear. Understanding this path is critical, especially for smaller companies that lack the massive resources of industrial giants.
A team of researchers set out to map this hidden path within the manufacturing sector of China, a nation where small and medium-sized enterprises drive a significant portion of the economy and its carbon output. They focused on a specific group of 343 manufacturing companies to trace how green supply chain practices transform into actual carbon reduction. The study, grounded in the idea that a company's ability to solve environmental problems is a valuable resource in itself, looked for a step-by-step progression. The researchers hypothesized that simply buying green materials or shipping efficiently would not immediately lower emissions. Instead, they proposed that these external practices must first trigger a chain reaction of internal improvements.
The investigation revealed a clear, sequential journey. It begins with green supply chain practices, such as sourcing sustainable materials and minimizing waste in production. These external actions do not directly slash carbon emissions on their own. Instead, they act as a catalyst that forces the company to adopt circular economy practices. In plain terms, this means the factory starts to think like a loop rather than a straight line. They begin to recover resources, redesign products so they last longer or can be easily taken apart, and manage their assets to ensure nothing goes to waste. The data showed that companies with strong green supply chains were significantly more likely to embrace these circular methods.
Once a company has established these circular habits, the next step in the chain naturally follows: green innovation. The ability to reuse materials and design for longevity sparks new ideas. Factories begin to develop cleaner technologies and create new products that are inherently less harmful to the environment. The study found that circular economy practices are a powerful engine for this kind of innovation. As these new, greener technologies and products take root, they strengthen the company's environmental management practices. This is the stage where the company formalizes its efforts, creating strict internal policies, monitoring systems, and continuous improvement plans to keep emissions in check.
Finally, this structured management of the environment leads to the ultimate goal: a measurable reduction in carbon emissions. The research confirmed that the journey from green supply chain practices to lower emissions is not a direct leap but a relay race. The external practices pass the baton to circular economy habits, which pass it to green innovation, which then hands it to formal environmental management, and only then does the carbon reduction happen. The study also identified a crucial factor that determines how fast this baton is passed. The commitment of top management acts as a powerful amplifier. When the leaders of a company are deeply dedicated to environmental goals, providing the necessary funds and strategic support, the link between their environmental management practices and actual carbon reduction becomes much stronger. Without this leadership commitment, the internal systems exist but are less effective at cutting emissions.
The findings offer a practical roadmap for factory owners and managers who feel stuck. It suggests that trying to cut emissions directly without building the intermediate capabilities is a futile effort. Instead, the most effective strategy is to start by strengthening green supply chain habits, which will naturally encourage the adoption of circular practices. This, in turn, will spark the innovation needed to formalize environmental management. The study emphasizes that for small and medium-sized enterprises, this step-by-step capability building is not just a nice idea but a necessary condition for success. By following this sequence, supported by genuine leadership commitment, these companies can finally translate their green intentions into the tangible, measurable reduction of carbon emissions that the planet needs.
