15 years of commitment
to Swiss sustainability
and cleantech
A little background...
Eric Plan, Secretary General of CleantechAlps
Launched in June 2010, CleantechAlps was born from the commitment of the Western Swiss cantons to position the region as a key player in the field of clean technologies. Faced with growing environmental challenges and the imperative of energy and environmental transitions, the platform has now established itself as a strategic lever for bringing together economic, academic, industrial, and institutional players around cleantech and sustainability.

Its slogan “Connect – Promote – Support” sums up its mission: to connect the aforementioned actors and promote their innovations in order to support the transition from the old carbon-based world to a globally more sustainable society. CleantechAlps is part of the regional innovation system, which brings together 4 sectoral platforms and 2 coaching services, managed by ARI-SO.
From the outset, CleantechAlps articulated a structured vision in three stages for the development of Swiss cleantech. A phase of emergence for the sector with quite a few initiatives, more or less opportunistic, but whose result was to help launch the dynamic (2010–2015).
Between 2015 and 2020, consolidation of the sector was expected in a context seen as broadly favorable.
From 2020 onwards, this vision foresaw a large-scale deployment over the following decade, up to 2030. This approach described the Swiss market as a pilot market, a springboard to the international stage. The ability to adapt a solution to the environment and context in which it is supposed to be deployed has proven to be a key asset in this sector.
While the figures demonstrate the accuracy of this vision to date (more than 600 start-ups created and £3 billion raised since 2010), we are currently halfway through this third phase, the completion of which will be decisive for the success of Swiss cleantech. The great challenge for the years to come has also been set. The aim is clearly to gain a foothold in international markets relevant to Swiss expertise. And while Switzerland has many assets to help it succeed in this final stage and ensure long-term growth, it must nevertheless shift into high gear. We are too slow in terms of commercialising innovations and we are not pulling together enough in the same direction. A genuine long-term collaboration, aligned with shared values, between the major players in the field (umbrella organisations, institutional bodies, public and private sectors) would be necessary. Switzerland is a very small country, and this is an asset that gives it an agility whose potential must be better exploited.
Highlights and key stages in the history of cleantech in Switzerland
The history of cleantech in Switzerland is marked by key stages and innovations that have contributed to the country’s energy and ecological transition. From the construction of the first infrastructures for renewable energies and water treatment to the adoption of ambitious national strategies, each event has advanced Switzerland toward a more sustainable future.

To conclude... Our vision for 2035+!
In 15 years, the Swiss cleantech ecosystem has grown from its early days to sustained growth. The current period goes well beyond a transition — we are witnessing a real revolution, leaving behind the (carbon-based) old world for a new, less carbon-intensive, more sustainable, and more responsible world.
Predicting the future is impossible… however, the accuracy of our 2010–2025 vision encourages us to share our estimations for the 2035 horizon in the following lines…
Read moreless
The current period has many similarities with 2010. At the time, cleantech was described as a “hype,” a trend whose interest seemed already declining in the US. Today, sustainability is being challenged from all sides — delays announced in Europe with the omnibus (CSRD, …) or fluctuating US tariff policies echo this. A very similar situation to 15 years ago, but with one major difference: the momentum of an established ecosystem!
Our vision for the years to come is clear: cleantech is the spearhead for implementing decarbonization plans, and sustainability is the driver that will help companies build resilience. Resilience is essential to withstand a turbulent environment increasingly subject to economic, political, climatic, or geostrategic crises.
Cleantech and sustainability will converge to become ultimately inseparable. In the coming decade, we will likely see a repeat of the quality management systems (ISO 9001) era, now under the “ESG” acronym. The challenge of this remake will be to avoid the bureaucratic excesses of ISO 9001 and instead leverage the lessons of the past 40 years.
Sustainability must be seen as a way to understand and mitigate risks in a turbulent environment. Implementing an ESG approach with its Environmental, Social, and Governance criteria is a risk management tool that will help companies, including SMEs, navigate a highly unstable and evolving environment. It acts as a compass to establish a roadmap and risk management strategy.
Our view is that a sustainability approach incorporating an analysis of the environmental footprint of a company and/or its key products will have become the norm in 15 years.
The priority work to achieve this is to demystify the subject, share concrete examples, and above all develop a pragmatic approach to accelerate the realization of these footprints. The goal is clearly to make them financially and humanly accessible to SMEs. For example, simplifying the creation of life cycle analyses or carbon footprints, by developing generic or industry-specific solutions… Some may call this utopia, to which we reply: let’s innovate!
The second essential axis to realize this vision is to continue the internationalization of cleantech solutions. The domestic market is very small and acts as a demonstration showcase, while growth clearly lies in foreign markets. In this context, and in addition to leveraging synergies among current initiatives, it would be wise to strengthen our presence in selected foreign markets with permanent showrooms.
These spaces — a sort of swissnex or industrial Swiss Business Hubs — would typically be venues where companies can showcase their solutions and equipment, make them available to clients, or run tests in their environments. Closer ties between multinationals and SMEs, for instance through partnerships with international groups headquartered in Switzerland, would further increase the impact of this initiative.
The rocket has launched: our collective challenge is now to ensure sustainable propulsion. This requires, immediately, stronger support for pre-industrialization and industrial scaling of solutions, supported by leveraging synergies between public and private actors.
The impact of climate change is no longer a distant horizon — it’s here and now. And the cleantech ecosystem already has the solutions. So… let’s meet again in 15 years for a new assessment. Until then: full speed ahead to action!
