Sustainable Business Models

Managing Sustainable Innovations - TUHH Institute for Technology & Innovation Management, Hamburg · part of my Technology Management MBA · study notes for revision.

---

The previous chapter was about putting sustainability inside an organisation - who the stakeholders are, competencies, embedding it in the culture. This chapter goes one level deeper and more dangerous: it asks whether the company’s business model itself is the problem. Because if the way a firm makes money is fundamentally at odds with sustainability, then tidying up the edges won’t save it. You have to redesign the engine, not just polish the paintwork.

Tip

The idea to hold on to. A business model describes how a firm creates, delivers and captures value. A sustainable business model does the same thing but for a broad set of stakeholders - including society and the environment - capturing economic value while creating social and environmental value (and, ideally, reducing the harm it causes). The trick that makes it work is decoupling revenue from resource use: earning more without consuming more.

1 · Why tweaking isn’t enough

Start with the uncomfortable part. If a company is built on an inherently unsustainable model, then incremental improvements - a cleaner process here, a recycling scheme there - don’t touch the core of the problem. They make a bad model slightly less bad.

Two examples from the lecture make this vivid:

• An oil company that makes its extraction greener has missed the point entirely. The real damage isn’t the carbon dioxide released while pumping oil out of the ground - it’s what happens when that oil is burned as fuel, or when the plastics made from it are incinerated at end of life. The harm is baked into the product, not the process.
• An electronics firm that improves worker health, safety and pay within its own factory walls has fixed a sliver of its true impact - if the devices are actually built by suppliers using conflict minerals and exploitative labour. The boundary of the “good deed” is drawn far too tightly.

The lesson: sustainability sometimes demands you rethink what value you create and how you make money from it, not just how efficiently you run the existing machine.

2 · What a business model actually is

A business model is simply the story of how a firm does business - how it turns a strategy into day-to-day processes that make money. The classic shorthand (think of the Business Model Canvas in one line) breaks it into three moves:

Value propositionwhat you offer & to whom

→

Value creation & deliveryresources, processes, supply chain

→

Value capturehow you earn revenue & profit

The three building blocks of any business model. The Business Model Canvas just fans these three out into nine boxes (customers, channels, partners, cost structure, and so on).

Building block	The question it answers
Value proposition	What product or service, for which customers, and why they’d choose you over a rival
Value creation & delivery	Which resources, capabilities, partners and supply-chain position let you actually produce and deliver that value
Value capture	How the money comes back in - the revenue model that turns all of the above into profit

3 · What makes a business model sustainable

A sustainable business model takes those same three blocks and reshapes them around a multi-stakeholder view. Instead of optimising value for shareholders alone, it aims to create monetary and non-monetary value for a wide range of stakeholders, and it holds a long-term perspective (Shakeel et al., 2020).

Two shifts matter:

• Value creation goes wider. Sustainability is woven into how value is created - not just for the paying customer, but for employees, communities, and the natural environment.
• Value capture goes both ways. A sustainable model reduces negative social and environmental impact and, at its best, captures positive social and environmental value - turning what used to be a side-effect into part of the point.

Conventional model shareholder value

• Creates value mainly for customers & owners
• Social and environmental effects are externalities - someone else’s problem
• Often earns more by selling more units
• More units → more resources consumed

Sustainable model stakeholder value

• Creates value for a broad set of stakeholders, society & environment included
• Social and environmental effects are designed in, not ignored
• Tries to earn while using fewer resources
• Revenue is decoupled from throughput

Note

The triple-layered canvas. One handy design tool is the triple-layered business model canvas (Joyce & Paquin, 2016): take the ordinary economic canvas and stack two more layers underneath it - an environmental layer (life-cycle impacts) and a social layer (stakeholder impacts). You end up with three canvases that line up box-by-box, forcing you to design economic, environmental and social value at the same time.

4 · The core tension: selling more vs. delivering more

Here is the knot every sustainable business model has to untie. A conventional model usually makes money the obvious way: sell more stuff. But making and selling more stuff almost always means using more materials and energy. Revenue and resource use are chained together - grow one, grow the other.

A sustainable model tries to cut that chain. It aims to decouple revenue from resource throughput (“throughput” = the flow of raw materials and energy pushed through the business). The goal becomes delivering the same benefit to the customer - a warm home, clean clothes, mobility - with less physical stuff flowing through.

Sell more units

→

Use more resources

→

More harm

vs

Deliver the outcome

→

Keep products in use longer

→

Value with less

The shift a sustainable business model tries to make: from “revenue rises only if throughput rises” to “revenue rises while throughput falls.”

This links straight back to eco-effectiveness and the circular economy from chapter 2: don’t just do the same linear thing a bit more efficiently (less bad) - redesign so materials keep cycling and value is delivered without a one-way flow of stuff to landfill.

5 · Sustainable business-model archetypes (Bocken et al.)

To make this practical, Bocken and colleagues (2014) reviewed a mountain of real cases and boiled them down into eight archetypes - repeatable patterns for building a business model that is more sustainable. They cluster into three groups, depending on whether the main innovation is technological, social, or organisational. A firm can pick one, or mix several.

Technological

• Dominant technical innovation
• Process & product redesign
• Maximise efficiency, close loops, go renewable

Social

• Dominant social innovation
• New consumer offering & behaviour
• Function over ownership, stewardship, sufficiency

Organisational

• Dominant organisational change
• Shift the purpose of the firm
• Repurpose for society, scale solutions up

The three groupings of Bocken et al.’s archetypes - technical, social and organisational routes to a more sustainable model.

Here are the eight, with what each one changes and a concrete example:

Group	Archetype	What it changes	Example
Technological	Maximise material & energy efficiency	Deliver the same value using fewer resources, less waste, less pollution	Lean and low-carbon manufacturing; additive (3D-printed) parts
Technological	Create value from waste	Turn waste streams into inputs - close the loop so “waste” disappears	Industrial symbiosis; cradle-to-cradle; take-back & remanufacture
Technological	Substitute with renewables & natural processes	Swap finite, polluting inputs for renewable ones or nature-mimicking designs	Switching to solar/wind; biomimicry; green chemistry
Social	Deliver functionality, not ownership	Sell the use or the result, not the physical object - product-as-a-service	Rental, leasing, pay-per-use; chemical management services
Social	Adopt a stewardship role	Take active responsibility for stakeholders’ long-term wellbeing across the chain	Fair-trade / ethical trade; radical supply-chain transparency
Social	Encourage sufficiency	Design to help customers consume less, not more	Slow fashion; durable products; no hard-sell marketing
Organisational	Repurpose for society / environment	Put social & environmental benefit ahead of profit in the firm’s purpose	Social enterprises; cooperatives; base-of-pyramid solutions
Organisational	Develop scale-up solutions	Spread a sustainable solution as widely as possible	Franchising, licensing, open innovation, crowdfunding

Caution

The framework isn’t perfect. It’s genuinely useful - it links the theory of business-model innovation to concrete, real-world mechanisms, and gives firms a menu to combine. But the lecture flags the downsides too: it leans environmental, so the social archetypes feel thinner; it builds on existing patterns rather than inventing new ones; and it under-weights softer factors like human creativity and skills. Use it as a checklist, not a bible.

6 · Circular business models, up close

Several of those archetypes are really circular business models - ways of keeping products and materials in use so you break the “sell more → use more” link. This is where the circular economy from chapter 2 becomes a revenue model, not just a design philosophy. Four patterns are worth knowing well:

Product-as-a-serviceSharingProduct-life extensionClosed-loop take-back

Four circular business models - each one earns money in a way that does not depend on shipping ever more new units.

Circular model	How it works	How it breaks “sell more → use more”
Product-as-a-service / leasing	Customer pays for use or outcome (per wash, per copy, per hour of light); the firm keeps ownership	The maker now wants durable, repairable products - a longer-lasting product earns more, not less
Sharing	One asset serves many users (tools, cars, spare capacity)	Meets demand with far fewer physical units in total
Product-life extension	Repair, refurbish, resell - keep the same product circulating	Revenue from service and second lives instead of new production
Closed-loop take-back	Firm collects products back and remanufactures or recycles them into new ones	Old products become feedstock, cutting virgin-material demand

The common thread: in each one, the company’s income is tied to delivering a benefit over time rather than to a one-off sale of a thing. That is exactly the decoupling from section 4, made operational.

Note

Product-as-a-service flips the incentive. In a normal sale, a product that breaks after two years means a repeat sale - planned obsolescence is quietly rewarded. Under a lease or pay-per-use model, a product that breaks early is your cost. Suddenly durability, repairability and upgradability are the profitable choices. The business model, not a slogan, does the work.

7 · How to design a sustainable business model

Building one of these is usually a deliberate act of business-model innovation - the holistic transformation of a firm’s core business logic, not the tweak of an isolated product. Sustainable business-model innovation adds the twist: create new or modified models that radically reduce negative effects and/or create positive ones for society and the environment (Schaltegger, Hansen & Lüdeke-Freund, 2016). A workable sequence:

1. Start from the value proposition - for all stakeholders. Ask what benefit you really deliver, and to whom, once society and the environment are counted as stakeholders too. Often the outcome (mobility, warmth, clean clothes) matters more than the product.

2. Rethink every building block for sustainability. Walk through creation/delivery and capture and redesign each: new partners, circular resource flows, a revenue model that rewards less throughput rather than more.

3. Watch for rebound effects and trade-offs. A greener, cheaper offer can backfire if people simply consume more of it (the rebound effect), or if a win on one dimension causes a loss on another. Check the whole system, not just the box you changed.

Good signs

• Revenue grows even as material throughput falls
• Value created for several stakeholders at once
• Incentives reward durability, reuse, sufficiency

Warning signs

• Cheaper/greener offer just drives more consumption (rebound)
• One dimension improves while another quietly worsens
• The “green” fix sits at the edge, not the core, of the model

Revision summary

Tip

The one-minute recap

• A business model = how a firm creates, delivers and captures value (the Business Model Canvas in one line). A sustainable one does this for a broad set of stakeholders - society and environment included - capturing economic value while creating social/environmental value and cutting harm.
• If a model is inherently unsustainable, incremental fixes miss the point - you have to redesign the engine (the oil-company and electronics examples).
• The core tension: conventional models earn by selling more units (more resources); sustainable models try to decouple revenue from resource throughput - deliver the outcome with less stuff.
• Bocken’s eight archetypes in three groups - technological (efficiency, value from waste, renewables), social (function-not-ownership / product-as-a-service, stewardship, sufficiency), organisational (repurpose for society, scale-up). Mix and match.
• Circular business models - product-as-a-service/leasing, sharing, product-life extension (repair/refurbish/resell), closed-loop take-back - each breaks the “sell more → use more” link and ties income to benefit-over-time.
• To design one: start from the value proposition for all stakeholders, rethink every building block, and watch for rebound effects and hidden trade-offs.
