How Supply Chain Mapping helps sustainability performance

March 18, 2024

We cannot talk about sustainable procurement without talking about supply chain mapping. It is a necessary process of establishing sustainable supply chain practices. For companies that want to use sustainable supply chain management, understanding supply chain mapping is really important.

In this article, we explain what supply chain mapping is, why it’s significant, how and where to start, and the benefits of mapping your supply chain.

What is supply chain mapping?

Supply Chain Mapping is the process of systematically documenting and analysing all input, activity, and process steps within a supply chain. It involves collecting all relevant information from the procurement of raw materials to the delivery and sale of finished products to gain a comprehensive understanding of the processes in this complex network structure.

By documenting the different steps and actors in the supply chain, a detailed visualization of the entire process can be created. This helps companies to uncover and eliminate weaknesses in the supply chain, minimize risks, and improve the efficiency and sustainability of their supply chains.

Why is supply chain mapping essential for sustainability?

Many ESG risks are buried within the supply chain. Mapping dramatically increases transparency, enabling you to identify potential ESG risks and address them.

Supply chain mapping is essential to sustainable procurement. Without the knowledge of where and how in the supply chain, risks may arise, and sustainable procurement would be an exercise in blind faith – worse still, a poor risk management practice. Investing resources into the mapping exercise will pay off in the long run for the reasons listed below.

  1. Compliance with regulations on supply chain due diligence
  2. Meet reporting requirements and attract ESG investors
  3. Early detection and mitigation of environmental or human rights issues
  4. Avoid supply chain disruptions and enhance business continuity
  5. Improve brand reputation and market positioning with a green supply chain

How and where to start mapping your supply chain

We have found that supply chain mapping is extremely important for sustainability. To get started with mapping, we recommend following these four tips below.

1. Take stock of your supply chain and existing information

The mapping process begins in your own supplier database. This is where you already have key information on your supply network, including…

  • … your geographical location
  • …your organisation size
  • … your number of employees, etc.

A point to consider is how many tiers in your supply chain you want to map. If going beyond the first tier, you also need to gather information on suppliers of suppliers to create a global map of their supplier network.

2. Risk Assessment

A risk assessment may be the most essential part of the mapping activity. This is where you identify risks at every point of the supply journey. At each farm, warehouse, transport hub, or other nodes, the materials and/or product passes through many hands and processes before arriving as a finished good. At any point along its journey, multiple risks exist that could disrupt this flow.

An extreme example would be a natural disaster at one of the factories, which damages physical assets such that resources or infrastructure become inaccessible, affecting production lead times. Another example: Raw materials are at risk of becoming in short supply if geopolitical tensions arise in the source location.

All these factors must be accounted for in the risk assessment, and any data that does not exist in your database should be collected from your suppliers. The data serve as indicators to assess the level of risk. Take the time to determine and catalogue metrics and indicators to measure each risk.

These are your tasks at this time:

  • Define what a healthy metric is.
  • Consider what actions you can take to address a problem that falls outside the healthy parameter.
  • Determine how you will monitor each metric over time.

These risks should be measured consistently and regularly over time as part of the risk management process.

Not all risks are known, but having a proper supply chain risk management framework in your company can help you to be prepared for any unexpected risks. Strong governance controls and response mechanisms can help you detect unknown risks earlier.

A risk management framework should consist of a matrix that ranks each risk on a scale of severity of its impact on the business, the likelihood of it happening, and your company’s preparedness to deal with it.

Risk assessment tools are available to assist with this process. If you want to take it a step further, these tools can perform advanced analytics that weighs your overall risk exposure and regularly monitors data changes and exposure levels.

3. Engage with suppliers to collect information

Before you engage with your suppliers to collect information, decide what information you need. This should be based on three factors:

  • The regulatory requirements that apply to your business, including reporting requirements
  • Investor requests for information that pertains to your supply chain, such as Scope 3 emissions data
  • The metrics and indicators for the risk assessment

4. Verify the information

Conduct checks on your suppliers to ensure the information shared is true and accurate. Checks are often conducted via visits to supplier premises. This also gives you the opportunity to pick up on risks during the visit that were not identified prior.

But physical visits are not the only way to audit the data. Asking for further specific information could lend insight into the discrepancies between statements on paper and actual practices.

Pay attention to ‘grey area’ ESG issues such as practices to avoid modern slavery, fair trade certifications, eco- or green certifications. Where certifications or labels are involved, it does not take much to verify them. In some places, for instance, there is no formal organic labelling system that can be verified by an independent third party. In such cases, labels should be researched and verified based on the issuing organisation and its legitimacy.

Benefits of supply chain mapping

The most valuable benefit of supply chain mapping is risk management. It allows you to identify risks in your supply chain that may present operational challenges or reputational damage to your business. A sustainable supply chain can only be achieved by mapping your supply chain, which unlocks ESG funding opportunities.

Here are other benefits of supply chain mapping:

  • Improved transparency: Supply chain mapping provides a clear overview of the entire supply chain, helping to identify and resolve issues more quickly.
  • Increased efficiency: Understanding the flow of goods and services within the supply chain can help identify inefficiencies and opportunities for improvement.
  • Improved collaboration: Supply chain mapping can improve collaboration between supply chain stakeholders, enabling better communication and coordination.
  • Improved sustainability: Supply chain mapping can help companies identify opportunities to reduce their environmental impact and increase sustainability.
  • Improved reputation: Adopting sustainable practices through supply chain mapping can help improve a company's reputation and brand image with customers, suppliers, and other stakeholders.

Final Tips to support your Supply Chain Mapping

Monitoring data in your supply chain is an exhausting activity that involves large amounts of time and resources. This process can be automated and organised easily in a cloud platform with the use of sustainability software designed for this very purpose. Software like this collects information on your behalf, tracking data changes right down to the data source, and even matches the data to ensure alignment with regulatory or reporting frameworks. We highly recommend using ESG software for supply chain mapping.
