Car clubs, bike shares, vacation rentals. As consumers, were becoming increasingly familiar with sharing or borrowing goods that have traditionally been owned, examples of whats known as an access-based business model.

Consuming access to products instead of the products themselves can play an important role in addressing environmental challenges. However, to meet future environmental challenges, we need to extend the application of access-based business models beyond finished goods, and rethink ownership of goods across the whole value chain.

Anaccess-based business modelis based on customers accessing the function or performance of goods, rather than owning them. Businesses that offer consumers access to products are increasingly emerging. In addition to cars, bicycles and homes, the model is available for clothing, power tools, headphones, detergent bottles and power banks. Offering access to products is also common between businesses, traditionally for large expenditures such as company cars or heavy machinery, and more recently also for products such as office furniture and lighting.

Access-based business models can tackle resource depletion, waste generation and other crises. Purchasing access, instead of products, makes consumption behaviour more sustainable by default, as it reduces the under-utilisation and rapid replacement of privately owned goods. In contrast to conventional linear consumption, the incentives to reduce consumption and return goods for reuse and recycling are built in. Car sharers, for example, were found toown 30% less cars than prior to car sharing.

Access to finished goods can, therefore, minimise the environmental and economic costs of manufacturing and consumption. Although the potential of access-based business models to address environmental challenges is recognised both economically and academically, the models have been slow to take off and their application predominantly to finished goods represents only a small fraction of the opportunity for impact.For example,as of 2014 the fleet of shared vehicles accounted for less than 0.1% of the almost 1 billion global in-use car fleet.

To solve global sustainability challenges, access-based business models will soon need to be applied not only to finished goods, but also to components and materials. What this means is that future material suppliers will no longer sell semi-finished goods like stainless steel sheets or PET granules instead, they will lease them out to product manufacturers, effectively selling components andmaterials as a serviceand offering their performance.

A supplier will, for example,lease stainless steelsheets to a car manufacturer to form the tubes for a chassis. Rather than owning the sheets, the car manufacturer will be charged to access the volume of material transformed into car chassis for an agreed period of time. At the end of this period, the car will be disassembled to allow the material supplier to retrieve the components and recycle the materials.

Such an approach creates anew ownership structurein which material suppliers own the components and materials, and the manufacturer only owns the value they have added by transforming them into the final product. In this model, components and materials cannot be physically consumed by the product manufacturer or the end-user of the product.

Just as car clubs build in incentives for sustainable consumer behaviour, this approach creates several important positive incentives for material suppliers and finished goods manufacturers. Because they retain ownership of their semi-finished goods, material suppliers will be incentivised to offer materials that are more efficient and durable and easier to recover at the end of product life, facilitating the shift towardsclosed-loop supply chains.

Committing to returning these materials will motivate product manufacturers to (re)design goods for access-based business models, rather than offering traditional goods for access. This will lead, for example, to the emergence of cars explicitly designed as goods that are leased instead of privately owned and using materials and components that stay in the value chain and are returned to suppliers instead of being scrapped.

To minimise recovery costs, material suppliers will incentivise product manufacturers to design for prolonged use of goods. They will also prompt manufacturers to design products that contain the least number of materials and are easy to disassemble, which will also make them easier to repair and enhance the purity of recycled materials.

Most importantly, with time-bound access to materials, product manufacturers will have to anticipate the moment when products become obsolete, design plans to intercept them and loop products back into production processes to reuse constituent components and materials. In this way product manufacturers will balance the operational cost of the components and materials they lease, against the revenue that they make from the products they sell or service. This structure will incentivise them to optimise material use, changing the game in resource management and leading to higher functional value provided by natural capital over a certain length of time.

Going one step further, this model can be applied not only to semi-finished goods, but also to minerals. Ownership of material resources does not have to remain with semi-finished goods suppliers. What if organizations upstream of material suppliers start to trade raw goods (i.e. unprocessed or minimally processed materials) without ownership exchange?

In the future, mining companies could lease raw goods to material suppliers using access-based business models, effectively offering minerals as a service. Moving a step further, nation states could stop giving rights for exploration or mining on certain lands to mining companies instead they could provide them with licence to mine permits that allow companies to mine but not to own the mined raw goods. For example, a nation state could lease iron ore to a mining company, who would then provide it to a steel and iron supplier. Ownership of mined minerals would remain with the country of origin and the licence to mine permits would come with the expectation that mined resources are eventually returned to the nation states in the original or processed form.

In an access economy, the complexity of modern finished goods will make it hard to recover the components, materials and minerals embodied in products and route them (back) to specific material suppliers. Hence, both current production and consumption systems and goods will have to be redesigned to service the model. In particular, goods will have to be optimised for reuse and recycling, and digital information embedded in them to ensuretraceability.

Infrastructure will have to emerge to intercept, separate, sort and recover materials. Further, all organizations in the value chain will have to adopt strategies for shared value creation and invest in ongoing collaborative relationships with partners over linear transaction-oriented relationships. Finally, addressing these challenges will not be possible without policy development and changes in culture and mindset from governments, businesses and consumers.

Chemical leasingis an example of component as a service business model offering the function or performance of chemicals in the manufacturing process. However, it lacks the dimension of returning chemicals at the end of use, which is key for a true circular solution.

Extending access-based business models throughout the value chain implies a systemic change to our production and consumption systems. This calls for a holistic review of the resource flows for finished, semi-finished and raw goods. The parties who have a stake in resource flows must come together to rethink ownership of goods in the three states to identify the opportunities to create commercial value and achieve sustainable impact. Simultaneous implementation of multiple access-based models might be appropriate in some value chains. Moving to new business models with new incentives can ensure that value chains are truly sustainable and help businesses play their part in protecting the earth and its resources.
