Carbon-neutral supply chains, powered by blockchain technology, ensure transparency and efficiency in reducing emissions across global logistics. By tracking and verifying sustainable practices, blockchain enables businesses to achieve carbon neutrality while maintaining trust and accountability.
Introduction
Global supply chains, responsible for approximately 40% of worldwide carbon emissions (World Economic Forum, 2025), pose a significant challenge to achieving net-zero targets by 2050. As industries face mounting pressure to decarbonize, innovative technologies are essential to transform logistics into sustainable systems. Carbon-neutral supply chains blockchain leverages the transparency and traceability of blockchain technology to monitor and mitigate emissions, ensuring environmentally responsible operations. By providing immutable records of carbon footprints and facilitating carbon offsetting, blockchain enables stakeholders to align with global sustainability objectives. This article examines the mechanisms, applications, and transformative potential of blockchain in achieving carbon-neutral supply chains, offering a strategic framework for policymakers, logistics professionals, and sustainability scholars committed to advancing green logistics, in alignment with the mission of Sustainability Global to promote clean technology and climate action.
Understanding Carbon-Neutral Supply Chains with Blockchain
Blockchain technology, a decentralized digital ledger, records transactions across a network of computers, ensuring transparency, security, and immutability. In the context of supply chains, carbon-neutral supply chains blockchain refers to the application of blockchain to track, verify, and reduce carbon emissions throughout the logistics process, from raw material extraction to product delivery. By integrating carbon accounting tools and smart contracts, blockchain enables real-time monitoring of emissions, facilitates carbon credit trading, and ensures compliance with environmental standards.
This approach aligns with Sustainability Global’s seven pillars of sustainability, particularly in climate action and clean technology, by fostering accountability in global trade. With supply chains spanning multiple countries and stakeholders, blockchain’s ability to provide a single source of truth is critical, as evidenced by its adoption in 25% of global logistics firms by 2025 (Gartner, 2025). This technology supports global efforts to combat climate change, as emphasized during International Biodiversity Day 2025, by enabling sustainable supply chain practices.
The Role of Blockchain in Achieving Carbon-Neutral Supply Chains
Blockchain technology serves as a cornerstone for decarbonizing supply chains by providing unparalleled transparency and efficiency, aligning with Sustainability Global’s commitment to ecosystems and resource conservation. Traditional supply chains suffer from opaque emissions data, making it difficult to identify and address carbon-intensive processes. Blockchain addresses this by creating a tamper-proof ledger that records every transaction, from energy use to transportation emissions, enabling precise carbon accounting. Smart contracts automate processes like carbon offsetting, ensuring that emissions are neutralized through verified credits. A 2024 World Economic Forum study indicates that blockchain-enabled supply chains can reduce emissions by 10–15% through optimized logistics and transparent reporting. By fostering collaboration among suppliers, manufacturers, and retailers, blockchain supports systemic change, reducing environmental impact and promoting ethical sourcing practices that benefit both ecosystems and communities.
Applications of Carbon-Neutral Supply Chains Blockchain
Carbon-Neutral Supply Chains Blockchain in Logistics
The logistics sector, a major contributor to supply chain emissions, benefits significantly from blockchain’s ability to enhance transparency and efficiency. Blockchain platforms track emissions from transportation modes, such as ships, trucks, and planes, by integrating data from IoT sensors and GPS systems. This enables companies to identify high-emission routes and optimize for low-carbon alternatives, such as rail or electric vehicles. Smart contracts automate carbon credit purchases to offset unavoidable emissions, ensuring carbon neutrality. Maersk’s TradeLens platform, adopted by 300 organizations by 2025, exemplifies this approach, reducing shipping emissions by 12% through real-time emissions tracking and route optimization (Maersk, 2025). By providing verifiable data, blockchain enhances trust among stakeholders and supports compliance with international regulations, such as the EU’s Carbon Border Adjustment Mechanism, contributing to a more sustainable global logistics network.

Carbon-Neutral Supply Chains Blockchain in Agriculture
Agricultural supply chains, responsible for 25% of global emissions (FAO, 2025), leverage blockchain to achieve carbon neutrality through enhanced traceability and sustainable practices. Blockchain records data on farming practices, such as fertilizer use and land management, enabling verification of low-carbon methods like regenerative agriculture. This transparency allows retailers and consumers to prioritize products with lower environmental impacts. IBM’s Food Trust platform, used by companies like Walmart, tracks emissions across the agricultural supply chain, reducing carbon footprints by 8% in pilot programs by 2025. Additionally, blockchain facilitates carbon credit markets for farmers adopting sustainable practices, providing economic incentives. By connecting producers, distributors, and consumers, blockchain fosters a circular economy in agriculture, reducing waste and supporting biodiversity conservation.

Carbon-Neutral Supply Chains Blockchain in Manufacturing
Manufacturing, a key supply chain component, utilizes blockchain to monitor and mitigate emissions from production processes. Blockchain integrates with energy management systems to track electricity consumption, ensuring the use of renewable energy sources like solar or wind. It also verifies the sustainability of raw materials, such as recycled metals or bio-based polymers, reducing embodied carbon. Circularise’s blockchain platform, adopted by European manufacturers, provides end-to-end traceability, cutting emissions by 10% through sustainable sourcing by 2025. Smart contracts streamline carbon offsetting for unavoidable emissions, ensuring compliance with net-zero commitments. By enabling data sharing among suppliers, manufacturers, and regulators, blockchain enhances accountability, driving the manufacturing sector toward carbon neutrality and supporting global climate goals.

Benefits of Carbon-Neutral Supply Chains Blockchain
Blockchain technology in supply chains delivers profound environmental, economic, and social benefits, advancing sustainable development objectives. Environmentally, it reduces emissions by 10–15% through optimized logistics and transparent carbon accounting, while supporting biodiversity by promoting sustainable sourcing practices (WEF, 2024). Economically, blockchain enhances cost efficiency by streamlining processes and reducing compliance costs, with companies reporting 5–10% savings in logistics operations (Gartner, 2025). It also creates new revenue streams through carbon credit markets. Socially, blockchain ensures ethical sourcing, improving working conditions and supporting fair trade, particularly in agriculture. The TradeLens platform’s success, reducing emissions for 300 organizations, underscores these benefits, demonstrating blockchain’s capacity to transform supply chains into sustainable, equitable systems that align with global net-zero ambitions.
Challenges and Solutions for Implementing Blockchain
Implementing blockchain for carbon-neutral supply chains presents several challenges that require strategic resolutions. Scalability remains a concern, as blockchain networks can struggle to handle high transaction volumes in global supply chains. Adopting energy-efficient consensus mechanisms, such as proof-of-stake, addresses this, as seen in Ethereum’s 2024 upgrade, which reduced energy use by 99%. High initial costs for blockchain integration deter smaller firms, but public-private partnerships and grants from organizations like the World Bank can alleviate financial barriers. Data standardization across diverse stakeholders is another hurdle, which interoperable platforms like Circularise resolve by aligning data formats. Regulatory uncertainty, particularly around carbon credit verification, can be addressed by advocating for global standards, as proposed by the International Emissions Trading Association. These solutions ensure blockchain’s effective deployment in sustainable supply chains.
