Greener Supply Chains: Driving Sustainability in Logistics

Writer's picture: Karen MwauraKaren Mwaura

With logistics accounting for nearly 10% of global GDP, the role of sustainability and ethics in supply chain management has become increasingly crucial. These principles are now being incorporated into companies' operations to ensure future sustainability and address social responsibilities. Here’s how these changes are making a difference today.


The logistics sector has one of the largest emissions footprints, contributing approximately 3% of annual global greenhouse gases. Shipping and road freight are among the largest contributors. Addressing these emissions has become a priority as industries strive to align with international climate goals. Practical measures such as AI-driven route optimisation, alternative fuels, and electrified fleets are being employed to minimise environmental impact. Beyond transportation, sustainable sourcing and the use of renewable energy are becoming standard practices in responsible supply chain management.


Recent regulations underscore the urgency of these measures. In the United States, the Clean Shipping Act mandates that all vessels above 400 gross tonnage operate with zero emissions in US waters by 2040. Shore power facilities will also be required by 2030 to reduce emissions while docked. Meanwhile, under the Paris Agreement, the European Union has committed to cutting shipping-related emissions by 55% by 2030, compared to 1990 levels. These stringent targets reflect a global push towards decarbonisation in logistics and shipping.


Social responsibility within supply chains is equally critical. Ensuring fair labour practices, ethical sourcing, and community engagement are no longer optional but imperative. Companies are adopting policies that promote worker welfare, support local economies, and ensure safe working conditions throughout their supply chains. By focusing on these areas, businesses not only secure their operations but also contribute to broader societal goals.


Strong governance is the cornerstone of effective ESG practices. Transparency across supply chain operations is essential, and innovative technologies like blockchain are enabling this. Blockchain ensures traceability of products from origin to delivery, mitigating risks of fraud and non-compliance. Companies adopting such technologies build trust with stakeholders and streamline their reporting processes, offering a competitive edge in the market.


Prominent examples highlight these practices in action. DHL has committed to achieving zero emissions by 2050. The company employs advanced strategies, including route optimisation and the electrification of its fleet, to significantly reduce its carbon footprint. Similarly, Unilever demonstrates leadership by collaborating with suppliers to implement sustainable sourcing and emission-reduction practices, while actively supporting smallholder farmers with training and resources.


For businesses looking to integrate ESG into their supply chain strategies, the following steps are pivotal:

  1. Define Measurable Goals: Setting clear targets, such as reducing emissions by a specific percentage over a defined period, creates accountability and direction.

  2. Collaborate with Suppliers: Building partnerships and providing support to suppliers ensures alignment with ESG objectives.

  3. Invest in Technology: Incorporating tools like AI for logistics planning and blockchain for transparency can significantly enhance ESG outcomes.


Challenges remain, including initial implementation costs and navigating diverse regulatory landscapes. However, the benefits outweigh the obstacles. Energy-efficient practices and optimised logistics eventually lead to cost savings. Additionally, adhering to ESG standards minimises risks associated with non-compliance and reputational damage.


The future of ESG in supply chains points to increased regulatory oversight and technological advancements. Maritime logistics is exploring biofuels and slow steaming to reduce emissions, while air freight is testing sustainable aviation fuels. These innovations, coupled with growing consumer demand for sustainable products, underscore the imperative for businesses to act.


Integrating ESG into supply chain management is essential for building sustainable and ethical business practices. By focusing on environmental impact, social responsibility, and strong governance, companies can not only improve their operations but also gain a competitive edge. As the importance of ESG continues to rise, companies that adopt these principles will be better positioned for long-term success.
