Sustainable Innovation
Managing Sustainable Innovations - TUHH Institute for Technology & Innovation Management, Hamburg · part of my Technology Management MBA · study notes for revision.
Chapter 1 defined sustainability and chapter 2 gave us the strategies for decoupling. This chapter is where those ideas meet the day job of most technology managers: innovation. The uncomfortable headline first - not every innovation is sustainable. A faster phone, a cheaper plastic bottle, a slicker app can all be genuine innovations and still make the world’s environmental and social ledger worse. So the question here is precise: what has to be true for an innovation to count as sustainable, and how does that change the way we run the innovation process?
1 · What makes an innovation “sustainable”
Section titled “1 · What makes an innovation “sustainable””An innovation is simply a renewal or improvement that reaches the world - a new product, service, process, or way of organising. The word “sustainable” adds a hard test on top: the improvement has to register on all three dimensions of the triple bottom line (economy, environment, society) that we met in chapter 1. Miss one and it is just an innovation.
Two further points from Bos-Brouwers (2010) are worth pinning down:
- It is the integration that sets it apart. The thing that distinguishes a sustainable innovation from a conventional one is precisely that it weaves economic, social and environmental aspects together. This is why “not every innovation is sustainable” is not a slogan but a definition - the label is earned only by the ones that integrate all three.
- They tend to be radical, not incremental. Sustainable innovations are usually radical or transformational by nature (Rycroft and Kash, 2000) - they change the system rather than tweak a product. An incremental innovation is a small step improving what already exists (a slightly more efficient engine); a radical one rethinks the whole approach (rethinking mobility so the car trip is not needed). Real sustainability gains usually need the second kind, because the deep footprint is baked into the system, not the last five per cent of efficiency.
A quick illustration of the incremental / radical gap on the same everyday need - getting from A to B:
| Incremental innovation | Radical / transformational innovation | |
|---|---|---|
| Move | Make the petrol engine 5 per cent more efficient | Rethink mobility so the trip is shared, electric, or unnecessary |
| Footprint effect | Trims the last slice of impact | Changes the system that creates the impact |
| Typical result | Real but small; often eaten by rebound | Large, but riskier and slower to land |
2 · Conventional vs sustainable innovation
Section titled “2 · Conventional vs sustainable innovation”If sustainable innovation were just “normal innovation, but greener”, it would be easy. It is not - the economics and the cast of characters both change. The clearest map of the differences comes from Weissbrod (2019).
- Need is private / corporate - a customer wants it, or the firm wants growth.
- Players: the private- and corporate-problem holder, plus knowledge and infrastructure holders.
- Single externality - spillovers appear once, in the innovation phase.
- Classic challenges: funding, innovation culture, tax & regulation, skills, coordinated support, reading future demand.
- Need also includes a public one - an environmental or social problem, not just a private want.
- Adds a new actor: the public-problem holder (society, regulators, future generations) on top of all the conventional players.
- Double externality - spillovers in both the innovation and the diffusion phase.
- All the conventional challenges plus directional risk, defining success, user-vs-system design, and governance for collaboration.
The four differences, side by side
Section titled “The four differences, side by side”| Dimension | Conventional innovation | Sustainable innovation |
|---|---|---|
| Nature of the need | Private and corporate - someone will pay | Private and corporate plus public - environmental and social needs count |
| Who is in the room | Private- and corporate-problem holders, knowledge & infrastructure holders | All of those plus a public-problem holder |
| Externality problem | Single externality (innovation phase only) | Double externality (innovation and diffusion phase) |
| Extra challenges | Funding, culture, regulation, skills, demand forecasting | The conventional set plus directional risk, success definition, user-vs-system duality, governance for collaboration |
The double-externality problem - why the incentive breaks
Section titled “The double-externality problem - why the incentive breaks”An externality is a cost or benefit that lands on someone outside the transaction - the innovator does the work, but part of the value (or harm) spills over to others who did not pay. A positive externality means the innovator cannot capture all the value they create, which quietly weakens their reason to invest in the first place.
nothing extra
Here is the mechanism in plain terms. In conventional innovation there is one positive externality: while you invent, some of your new knowledge leaks to competitors (the innovation-phase externality). That already dampens investment, which is why patents and subsidies exist.
Sustainable innovation carries a second one. When the clean product actually diffuses - spreads into use - its environmental and social benefits (cleaner air, better health, lower emissions) flow to society at large, not to the firm’s bottom line. Nobody writes the innovator a cheque for the cleaner air. So the private incentive to invest is weakened twice: once in the lab and again in the market. This is the core reason sustainable innovation tends to be under-supplied by markets alone, and why the public-problem holder - regulation, procurement, standards, public funding - has to step in to close the gap.
The new challenges that come with it
Section titled “The new challenges that come with it”Beyond the money problem, four fresh management headaches show up:
- Directional risk - with conventional innovation the market tells you if you aimed right (people buy it or they don’t). With sustainability the “right direction” is contested and long-term, so you can invest heavily and still be pointed at the wrong problem.
- Defining and evaluating success - profit is one number; environmental and social value are many, and slow to show up. What counts as “a win” is genuinely harder to state and measure.
- User-vs-system design duality - you have to design for the individual user (a car someone wants to drive) and for the system (a mobility system that works if millions switch). Optimising one can wreck the other.
- Governance for collaboration - because a public-problem holder is now in the room, you need ways to steer partnerships across firms, government and civil society - messier than a single-company project plan.
3 · Sustainable innovation strategy - the Pentathlon lens
Section titled “3 · Sustainable innovation strategy - the Pentathlon lens”So what has to change strategically to keep producing these innovations? A useful frame is the Innovation Pentathlon (Goffin, Herstatt & Mitchell) - a picture of the whole innovation system as three activities standing on two foundations.
The Pentathlon’s own question is exactly the exam question here: what do you change in your innovation strategy so that sustainable innovation actually comes out of it? Sustainability is not a fourth box you bolt on - it has to be threaded through the foundation so it shapes every activity above it:
| Strategy element | Conventional emphasis | Sustainable shift |
|---|---|---|
| Targets | Revenue, market share, time-to-market | Add explicit environmental & social targets (emissions, circularity, fair supply) |
| Metrics | Financial KPIs, sales | Life-cycle footprint, resource intensity, social impact - measured, not assumed |
| Roadmaps | Feature and platform plans | Plans that reach past launch into use, maintenance and end-of-life |
| Partnerships | Suppliers, channel, tech partners | Add the public-problem holder - regulators, NGOs, cities - to share the double externality |
| Selection criteria | Business case, risk-reward | Business case screened through the three dimensions, not around them |
The through-line: because the private incentive is weakened by the double externality, sustainable strategy leans hard on partnerships and shared targets to make the numbers work - you deliberately bring in the actors who benefit from the public value so someone actually pays for it.
4 · Sustainability in the innovation process - extending Stage-Gate
Section titled “4 · Sustainability in the innovation process - extending Stage-Gate”Strategy sets direction; the process is how a firm walks an idea from “wouldn’t it be nice” to “on sale”. The standard reference is Cooper’s Stage-Gate model (1980s, Robert G. Cooper) - a blueprint that breaks new-product development into a fixed set of stages (cross-functional work) separated by gates (Go / Kill decision meetings that act as quality checkpoints).
And that stopping point is the whole problem. Classic Stage-Gate ends at Launch - the product’s actual environmental and social life (years of use, then disposal) happens after the process has closed the file. To make it sustainable you do two things: extend the pipeline past launch, and pull life-cycle thinking into the front end.
Extend the pipeline: add life-cycle stages after launch
Section titled “Extend the pipeline: add life-cycle stages after launch”The sustainable version (building on Cooper, 2014 and Flores et al., 2018) keeps the five stages and adds two more that follow the product into the real world:
continues
- Stage 6 - Usage & Maintenance. The years the product spends in use (its “product life”) are where most of its footprint is actually spent - energy, consumables, repairs. Designing for this stage means durability, repairability, and after-sales service that extends life rather than pushing replacement.
- Stage 7 - Retrieve the product and apply the “R” principles. At end of life you don’t just dispose of it - you retrieve it and run the R principles: reduce, reuse, recycle (and their cousins, repair, refurbish, recover). The retrieved materials and lessons feed back into Discovery, which is what turns a straight line into a loop.
The R principles in Stage 7 are usually ranked - the earlier ones keep more value in the loop, so a good design tries them in order before falling back to the next:
| R principle | What it means | Value kept |
|---|---|---|
| Reduce | Need less material / energy in the first place | Highest - the impact never happens |
| Reuse | Use the same product again, as-is | Very high - no reprocessing |
| Repair / Refurbish | Fix or restore so it keeps working | High - extends the product’s life |
| Recycle | Recover the raw materials for new products | Moderate - material saved, product lost |
That loop is the process-level expression of chapter 2’s eco-effectiveness / cradle-to-cradle idea: waste from one cycle becomes a nutrient for the next, so the design aims to close the material loop rather than merely slow the leak.
Pull life-cycle thinking into the front end
Section titled “Pull life-cycle thinking into the front end”So the gates change too. In a sustainable process, each Go / Kill decision is screened not only on “will it sell and make money?” but on “does it hold up across all seven stages and all three dimensions?”. A project that looks great to launch but has no answer for Stage 7 should stall at the gate - that is the process doing its job.
5 · Seeing it whole - a brief real-world example
Section titled “5 · Seeing it whole - a brief real-world example”It helps to see the three dimensions integrated in one company rather than as a checklist. Toyota is a useful case (we study it in full separately, so just the shape of it here). Facing falling sales and the question of what sustainable growth even means, Toyota reached past a quick financial fix and adopted a “tree-ring” (Nenrin) philosophy - grow slowly and steadily, adding a ring at a time, like a tree, rather than sprinting for one big season. Read against this chapter, that is a firm choosing the long-term half of the definition and treating growth as something to pace across economic, environmental and social health together, not maximise on one axis. Nike tells a similar story from the product side - redesigning materials and manufacturing so that environmental and social gains are engineered into the product, not apologised for afterwards.
The common thread - and the honest limit - is that no organisation is ever “completely sustainable”. Sustainable innovation is a direction of travel: integrating all three dimensions, a bit more radically and a bit further across the life cycle, each ring.
