Sustainability in Supply Chains: How Companies Are Reducing Their Carbon Footprint

Sustainability has become a pertinent issue for businesses, especially in terms of supply chains, as the envelope of critical problems in the world opens up more in the ways of climate change and environmental degradation. The supply chain, covering the entire lifecycle of products-from raw material to end consumer, is responsible for a portion of global carbon emissions, whereby an increasing number of companies have started to place themselves in the direction of reducing the carbon footprint of their supply chains, as well as the corporate social responsibility-internal government it reflects, and more stringent-internal frameworks.

This article is looking at how different businesses across industries adopt sustainable practices to limit their carbon footprint, what benefits accrue from such activities, and the emerging challenges in the course of practice.

The Carbon Footprint of Supply Chains

Thus, according to the World Economic Forum, it would be the supply chains that account for over 80 % and more in terms of total greenhouse gas emissions of a company. And thus, emissions of the supply chains must be addressed, if the company intends to reach global climate targets. For the greenhouse gas emissions, these primarily ales from freight and logistics; energy consumption in factories, wastes generation, and sources raw material. So, in these major three areas relating to the supply chains, the companies have put this effort to reduce carbon emissions: procurement, transportation, and manufacturing.

Strategies for Reducing the Carbon Footprint in Supply Chains:

1. Sustainable Sourcing and Procurement

Sustainable sourcing is the consideration of materials and suppliers with preferences for environmental conservation, socially responsible production, and fair labor practices. More companies are partnering with suppliers offering low-carbon products or services or using renewables in their production processes.

Unilever is committed to sourcing 100% of its agricultural raw materials sustainably by 2025. Among other initiatives, it works with farmers to prevent deforestation, enhance soil quality, and reduce emissions in agricultural practices. Moreover, the organization aims to achieve carbon neutrality in its entire supply chain by 2039.

In the similar way, IKEA has committed to sourcing 100 percent cotton and wood from sustainable sources such as forest certification schemes like Forest Stewardship Council that ensure materials are coming from responsibly managed forests.

Like it, IKEA is also committed to sourcing from 100 percent sustainable cotton and wood-from forest certification schemes, such as Forest Stewardship Council that guarantee the well-managed forests for the materials.

2. Energy Efficiency and Clean Energy Transition

Manufacturing processes in supply chains are the greatest contributor to carbon emissions, especially where activity involves energy-intensive industries, such as chemicals, steel or cement production. The cure for such has been to adopt energy-efficient technologies and transition to renewable forms of energy.

For instance, Tesla has invested heavily in renewable energy for its factories, including solar power for its Gigafactories. The company is looking to use cleaner energy in powering production and consequently reduce carbon footprint. Further, this principle of sustainability is evident in the electric vehicles manufactured by Tesla as they also serve to curb emissions from the transportation sector.

Microsoft has also been a leader in sustainable supply chains. The company has set a goal to become carbon-negative by 2030. To achieve this, it is transitioning its global data centers to renewable energy sources and working with suppliers to reduce their carbon emissions. Microsoft has also pioneered a “supplier sustainability scorecard,” which helps track the environmental impact of suppliers and incentivizes them to reduce their emissions.

3. Carbon-Neutral Transportation and Logistics

According to the International Energy Agency (IEA), transportation accounts for roughly 14% of emissions from global sources, making such an important part of greening supply chains. "Without it," he believes, "you cannot create green supply chains." Decarbonized supply chains would have a lot of devices through which carbon footprints are reduced from their logistics strategies. About 57% of actual plans or strategies for decarbonizing logistics involve investments in electrification of ports and transportation systems, while, for example, 41% invest in optimizing routes and the reduction of packaging. By 2030, the company plans to add a total of up to 10,000 electric delivery vans, including investments in electric delivery vans, with the aim of going completely electric in its delivery fleet. Amazon will additionally run all its operations worldwide on 100% renewable energy by 2025.Another way is developing a logistics network that will reduce both distance and frequency of shipment. PepsiCo is now using solutions driven by data so that the company can consolidate shipments and optimize routing. This will lead to a reduction in emission and increase its operational performance resulting in cost savings.

4. Circular Supply Chains

Today, most businesses are conscious of the reality that reducing carbon footprints within their supply chains would go hand in hand with working with suppliers and other industry actors. For instance, Walmart has initiated Project Gigaton, which focuses on reducing greenhouse gas emissions by 1 billion metric tons from its supply chain by 2030. This program encourages suppliers to take on sustainable practices, including reducing their emissions, reducing waste, and harnessing renewable energy for their operations.

However, companies and suppliers should be engaged in this kind of learning as they co-create new technologies. They can further invest in innovation working together to promote their sustainable agendas. This fundamentally adds up to joint action on a bigger scale for a broader change across the whole industry.

5. Collaboration with Suppliers and Industry Partners

Most companies these days are aware of the fact that reducing the carbon footprint in their supply chains would require working with suppliers and other stakeholders from the industry. For instance, Walmart has introduced an initiative called Project Gigaton, aimed at cutting down greenhouse gas emissions by 1 billion metric tons from its supply chain by 2030. This initiative seeks to encourage suppliers to adopt sustainable practices, including cutting their emissions, minimizing waste, and using renewable energy.

Instead, companies and suppliers might learn from each other while developing new technologies and invest together in improving sustainability. This means collective action for a more significant collective change across entire industries.

Challenges and Barriers to Sustainability in Supply Chains

While the momentum for sustainability is gaining ground, companies face a plethora of challenges in different spheres while applying the above strategies. Some of the major barriers are:

High Upfront Costs: Most of the sustainability projects involve huge costs in purchasing energy-efficient appliances or in a switching process from other energy sources to renewable ones. Small businesses are often unable to easily assume the financial burden of those changes.

Complexity of Supply Chains: In global supply chains, the supply chain has become highly complicated with many tiers of suppliers across different regions. Companies usually are not able to track and influence the entire supply chain for sustainability.

Lack of Data and Transparency: Most companies do not have the necessary data and transparency to make reliable estimations of the carbon footprint of their supply chains. Hence, gathering such data to devise proper strategies for emissions reduction becomes difficult.

Resistance to Change: Some suppliers and other stakeholders tend to show resistance to adopting sustainable practices since it is costlier or they do not understand the gained benefit in time.

Reducing the carbon footprint in supply chains is part and parcel of climate action. As consumers, governments, and investors increase demand for sustainability, businesses are launching various initiatives to render their supply chains more environmentally friendly-from sustainable sourcing and clean energy transitions to circular supply chains and collaboration with suppliers, to mention a few-on the carbon footprint reduction agenda.

There are challenges, such as high costs and complexities in the supply chain, but the advantages, both environmental and financial, are considerable. Therefore, in the future, supply chains are likely to be characterized by lower emissions, greater efficiency, and more responsible attitudes toward production and consumption as businesses continue investing in sustainability.
