How to green your export supply chain

How to green your export supply chain article image

With everyone thinking green these days, businesses are looking for ways to reduce their carbon footprint. Supply chains have the potential for the most green gains and exporters are in a good position to lead. Here are some considerations for a more eco-conscious supply chain. Environmental issues have dominated the media headlines recently, with government agencies, businesses and the general public all thinking about how to reduce their carbon footprint on both the local and global environments. Many corporations have followed suit, announcing green packaging programs, recycling initiatives and other corporate social responsibility campaigns to publicly demonstrate their green behaviour. Laudable as these are, it remains the case that inefficient transportation methods in the modern supply chain represent a significant part of the ecological problem, well illustrated by Eye For Transport’s Green Transportation & Logistics Report that found that as much as 75 percent of a company's carbon footprint comes from transportation and logistics alone. Today, changing consumer sentiment and the complexity of global trade forces companies to modernise their supply chains with a shift away from the focus being on transport optimisation purely in terms of freight cost and utilisation, towards one that increasingly considers how the ecological impact of the supply chain on the wider environment can be minimised. This idea of a green supply chain is not new. From its beginnings in Scandinavia and Germany, areas often considered the most ecologically conscious in Europe, it has grown to become a global movement towards green transportation thinking and lean supply chain principles. Food mileage Take as an example the growth in organic food: the dramatic increase in demand and the need to meet this with production from a more geographically extended supplier base has necessitated a change in our understanding of the true environmental cost of a product. From what was originally a choice based primarily upon the ethical conditions in which food is reared or grown, it has now become one of understanding how the products themselves are grown, how they are brought to market, and the carbon impact of all the constituent elements. It’s all very well selecting a packet of organic beans because less pesticides and fertilisers are used in their production, but if getting them on the shelf requires air-freighting them thousands of miles, then the choice becomes more difficult to justify. To compound matters, what if the locally produced organic beans are grown in poly tunnels using artificial heat and light whereas the imported beans grew under natural conditions? What now is the best green decision and how far do you go in this analysis? Should you, for example, incorporate the environmental impact of the energy source of the power supply for the artificial heat and light as opposed to that of the oil refinery that generated the fuel used for the aircraft flying from the remote supplier? The more you analyse, the more difficult the decision becomes. Many supply chain professionals are beginning to recognise the importance of efficient green supply chains. A recent study found that 94 percent of European supply chain professionals rate green issues as a business priority. The increased awareness within the industry has rightly encouraged companies to re-think their transportation strategies. However, as the modern supply chain consists of hundreds of decisions and processes, each with discrete economic and environmental implications, remodelling a supply chain has to be balanced against the impact on existing relationships and procedures. So how does an organisation tune its supply chain to reflect environmental best practices and at the same time ensure an efficient transportation process to meet demand? An interesting case study was highlighted in a UK government report identifying the environmental benefits obtained by changing the supply chain model. The example was Tesco, which adopted an approach whereby trailers were adapted to be suitable for both pick-up from suppliers in pallets and delivery to stores in roll-cages, roles that had traditionally been operated independently. By combining store delivery with supplier pick-up, Tesco reduced total mileage by 3 million miles, reduce fuel consumption by 1.7 million litres and reduce CO2 emissions by 4,600 tons. At the time the green supply chain was not a recognised concept, yet it is fascinating to see the environment benefits accrued from such innovative processes across the supply chain. Define and measureIn the current climate it is vital that companies can both define and measure each element within the supply chain. Benchmarks can then be rolled out across the network to evaluate the impact of any changes made. If operating a green supply chain were purely an altruistic exercise then companies would simply choose the most cost-effective carrier using the most ecologically friendly mode of transport and set of assets. However, corporations have to balance this against the need to remain profitable, which brings into play a far wider set of variables. Take something as apparently simple as the choice between two road carriers. Assuming both have available capacity, typically the selection will come down to who can meet the required service level at the lowest cost. But what if one has a new, environmentally friendly fleet of vehicles that are driven efficiently, whereas the other has an older fleet, a less rigorous maintenance policy or fewer checks on driving habits? If we are to take account of the resulting environmental impact, then the choice may prove less predictable. We can illustrate this better in a simple scenario where we have two carriers, A and B, which have freight costs as well as carbon costs. The freight costs, A1 and B1, represent the basic freight rates the carriers would charge for their services. As can be seen, all other things being equal, carrier B would be selected. For the sake of the example let’s now assume two things; first that a carbon factor is at least recognised if not applied. This could be in the form of either a straight taxation payment or some form of carbon offset. Second, we assume Carrier A has the lower carbon footprint. We can then see that the fully loaded cost may now favour Carrier A rather than Carrier B, the cost of AT being lower than the cost of BT. In this example, companies will be interested in evaluating a number of cost elements including:

  • The freight cost payable without carbon loading being imposed, i.e. B1
  • The additional freight cost payable by selecting a more carbon-friendly carrier (A1 minus B1)
  • The respective fully loaded costs including both freight rate and carbon loading (AT and BT)
  • The carbon cost resulting from the optimised carrier selected, i.e. AT minus A1

Similarly, when one looks at the more traditional areas of transport optimisation such as consolidation of shipments, this has typically been based upon the ability to optimise freight utilisation while meeting required service levels at minimum cost. Again, in the case of the green supply chain it will also be necessary to introduce the variable of environmental impact, if by altering the shipment date this could lead to greater efficiency. In this case the resulting carbon offset may be shared between producer, transport provider and customer. In this scenario, the demand to have the shipment ‘by 9 tomorrow morning at whatever the cost’ may need to be revisited.

Technology has the answer When you consider the hundreds of processes and decisions involved in a supply chain it is understandable why the challenge of assessing the carbon footprint, let alone reducing it, is one that many companies hesitate to attempt. Technology is available that can sit across the entire supply chain network and can apply specific business rules and logic in conjunction with powerful algorithms. What is crucial is that the engines behind such technologies are designed to maximise transportation based not just on the traditional factors such as cost and asset use, but also flexible enough to incorporate these new environmental variables. With today’s complex globalised supply chains it is also necessary to be able to understand, evaluate and optimise all transportation, both domestic and international, both inbound and outbound, and from simple point-to-point to complex multi-modal, multi-leg and cross-docking operations. For many regional or global companies, lack of visibility leads to ‘maverick’ spends, typically airfreight or courier, which can form a significant proportion of overall transportation expenditure. When the information available is inaccurate, out of date, or simply not believed, the desire to be able to ‘see the inventory on the receiving dock’ results in rush orders being placed and shipments being delivered that duplicate those already in transit. The end-to-end visibility of logistics data, when available in the granularity and timeliness required, can be specifically tailored to the decision-making requirements of every collaborative partner in the global network. This is where information can be more valuable than inventory, and the savings in terms of carbon expenditure are obvious. Using technology in conjunction with the wider environmental strategies, together with appropriate statistical analysis, it will be possible to benchmark the current supply chain in terms of its environmental impact across different geographies and modes. Having achieved this, it is then possible to incorporate the carbon impact of any supply chain decisions more accurately, whether strategic or tactical, such as switching points of production, moving between different modes of transport and so forth. Environmental ministers and pressure groups such as the Carbon Trust have recently launched a carbon rating table for global corporations, a move to encourage the industry to measure the ecological impact of each product throughout its entire lifecycle. The response from international corporations has been extremely positive, with many household brands signing up to the project. However, for a company to truly limit its impact on the wider environment, it is critical to look across the board and at every element within the supply chain, whether delivered using internal resources or external supply chain partners. Today, there is an opportunity for companies to have a sophisticated supply chain that recognises its environmental impact while also driving business growth through a streamlined and agile network. -David Morgan is general manager, Supply Chain Edge Products at Oracle Corporation (Asia Pacific). Demands on suppliers Suppliers play a key role in helping build a sustainable supply chain. Whether they are SMEs or big companies, the ecological impact they have on the supply chain is scrutinised by their customers, particularly in larger organisations. For example, we deal with numerous small and medium-sized suppliers that need to comply with our Ethical Sourcing Policy to ensure we uphold the integrity of the supply chain. We look at how the products are manufactured from the beginning to the end, and have criteria SME suppliers need to adhere to. Some of the aspects suppliers should consider when making their supply chain more eco-friendly include the environmental impact of their products as well as the way they are packaged and transported. Environmental impact: The environmentally friendly feature of a product can be a point of difference for suppliers. Many products on the market have similar features and benefits. If a supplier can offer the same product but manufactured in a more sustainable way, this product becomes more valuable to large organisations. For instance, to be included in our ‘EarthSaver’ range, items must have at least 20 percent recycled materials or contain 70 percent content that is recyclable or biodegradable at the end of its life. Suppliers accredited to IS014001, or an equivalent environmental management system, are looked upon positively as this demonstrates that their products were manufactured to high environmental standards. Suppliers should also try to minimise the natural resources used in their manufacturing process to reduce their carbon footprint on the environment. Packaging: This is another aspect that can assist in making the supply chain more sustainable. Through involvement in the National Packaging Covenant (www.packagingcovenant.org.au), organisations can actively look for ways to reducing their packaging. Suppliers should optimise the use of their packaging by, for example, reducing product packaging or using recycled or biodegradable materials. In addition to minimising waste going to landfill, an optimum use of packaging can also assist in reducing operating costs. Transportation: To minimise carbon emissions, suppliers should ensure truck-full deliveries and review the distance and routes travelled by their delivery trucks. Suppliers can also offset their delivery emissions through carbon abatement programs such as Greenfleet. Although carbon footprints are only starting to figure on companies’ list of criteria when reviewing their suppliers, it will become more important as the government’s Carbon Pollution Reduction Scheme becomes implemented. -Jennifer Williams, CSR manager of Corporate Express Australia Limited People who read this, also liked: Eco-products on the rise Climate change and the export environment Running a greener fleet Energy efficiency program for small business
