Sustainability in supply chain engineering by reducing emissions and waste

Sustainability in supply chain engineering is no longer a ‘nice to have‘; it is a strategic necessity. As regulations tighten, customer expectations rise, and resource scarcity increases, companies are under growing pressure to understand and reduce their corporate footprint. 

At CAROZ: we believe that sustainability and efficiency go hand in hand. A well-engineered supply chain not only reduces emissions and eliminate waste, but also creates long-term value for your business. By rethinking your network, flows, and sourcing strategies, sustainability becomes an integrated part of your operational success and not just a compliance checkbox. 

Many companies struggle to see the link between supply chain engineering and sustainability, due to the topic’s complexity and broad scope​.  

This blog explores how supply chain engineering can drive sustainability. We outline its core principles, highlight the strategic benefits, and demonstrate how a neutral Control Tower specialist like CAROZ can help turn ambition into action. 

What is sustainability? 

Sustainability is often associated primarily with environmental concerns such as reducing emissions, minimizing waste and protecting natural resources. While these elements are undeniably important, true sustainability extends far beyond that. It also includes social responsibility, ethical governance and long-term economic resilience. A sustainable approach considers the well-being of employees, the integrity of supply chains and the ability of a business to adapt and grow over time. In essence, sustainability is not only about being environmentally conscious, but about building systems that are balanced, future-proof and responsible on every level. 

Sustainability is commonly divided into three core pillars, often referred to as the Triple Bottom Line. These pillars help organizations and policymakers take a more holistic view of sustainable development: 

1. Environmental Sustainability: This pillar focuses on the responsible use of natural resources and the protection of ecosystems. Key themes include reducing greenhouse gas emissions, minimizing waste, conserving water and energy, and protecting biodiversity. The goal is to operate in a way that does not deplete or permanently damage the planet’s resources.
2. Social Sustainability: Social sustainability centers around people and communities. It includes fair labor practices, diversity and inclusion, human rights, workplace safety, community engagement, and the long-term well-being of employees and stakeholders. This pillar ensures that organizations contribute positively to society and respect the rights and dignity of individuals.
3. Economic Sustainability: Economic sustainability is about creating long-term value and financial stability without compromising the other two pillars. It involves responsible business practices, ethical governance, innovation, and resilience. The focus is on building a business model that remains profitable while contributing to sustainable development.

What is sustainable supply chain engineering?

Sustainable supply chain engineering refers to the design, optimization, and continuous improvement of supply chain systems with a focus on minimizing negative environmental and social impacts while maintaining operational efficiency and economic viability. It’s about combining the three pillars mentioned above (environmental, social, and economic) to create a supply chain that is resilient, responsible, and future-proof. 

For example, this includes: 

• Redesigning supply chain networks to reduce unnecessary transport and emissions 

• Selecting carriers and transport modes based on environmental performance and efficiency 

• Using data and software to improve planning accuracy and minimize waste 

• Ensuring transparency across all tiers of the supply chain 

The different in traditional supply chain design

Traditional supply chain design focused mainly on cost, service levels and lead times. Sustainability was often treated as a separate topic, if it was considered at all. This approach is no longer sufficient in today’s environment. Modern supply chain engineering places environmental impact at the core of the design process, evaluating CO₂ emissions, energy usage, packaging waste, and circularity alongside traditional performance indicators. 

As regulations tighten: energy prices rise and supply chain risks increase, companies are redesigning their networks to lower emissions, minimize waste, strengthen resilience and support circular business models. The goal is no longer just efficiency, but a supply chain that is responsible, future-proof, and aligned with climate ambitions.

Key components of sustainable supply chain engineering

As mentioned, sustainable supply chain engineering is about more than just reducing emissions; it involves rethinking the entire system. Below are five essential components shaping a more sustainable future: 

1. Network design and reengineering 
   Reducing transport distances and avoiding inefficiencies through smarter warehouse and route planning. 
2. Technology integration 
   Leveraging TMS and control tower solutions to simulate, optimize and monitor sustainability metrics throughout the chain. 
3. Collaboration and transparency 
   Working closely with partners to improve environmental performance across all supply chain tiers, which is increasingly important under CSRD requirements. 
4. Scenario planning 
   Testing various what-if scenarios to evaluate the trade-offs between cost, time and emissions before decisions are made.

Sustainability: THE CAROZ WAY  

Many companies struggle to translate their sustainability goals into real impact within their logistics operations. The reasons are clear: logistics networks are often fragmented across business units, regions, and partners. Data on emissions is incomplete or inconsistent, and reliable tools to evaluate the environmental impact of logistics decisions are often lacking.

As a result, strategic decisions such as modal shifts or network redesigns are difficult to assess in terms of CO₂ impact. Moreover, sustainability is frequently at odds with traditional KPIs like cost and lead time. Without the right visibility and tools, companies are forced to choose between environmental performance and operational efficiency, causing many green initiatives to stall in pilot phases.

How CAROZ helps: structured, neutral, and data-driven

At CAROZ, we turn ambition into measurable progress. As a neutral 4PL Control Tower, we help companies redesign their logistics footprint with a focus on both sustainability and performance in mind. We eliminate inefficiencies, reduce empty mileage, and evaluate low-emission alternatives such as rail or inland waterways, all independent from supplier interests.

CAROZ THE Control Tower offers the necessary insights through advanced tooling: simulating, optimizing and monitoring sustainability data across the entire supply chain. This includes reducing transport distances and voiding inefficiencies through smarter warehouse and route planning, ultimately helping to lower CO₂ emissions.

Thanks to our expertise and digital control tower infrastructure, we provide full visibility into your supply chain flows, enabling informed trade-off decisions between cost, service, and sustainability.
