In the world of elite athletics, the pursuit of performance is often measured by vertical gain, speed, and the conquest of seemingly impossible physical barriers. Though, for Nolwen Berthier, the definition of success has evolved from the sterile environment of indoor competition to a deeper, more systemic engagement with the natural world. By bridging the gap between high-performance climbing and environmental engineering, Berthier is redefining what it means to be a professional athlete in the era of climate change.
Berthier’s journey is marked by a distinct pivot. After spending a decade as a member of the French national climbing team, she made the conscious decision to step away from the competitive indoor circuit at the age of 24. This transition was not a retreat from challenge, but rather a shift in focus toward Nolwen Berthier climbing and ecology, where she began to interrogate the relationship between the climbing community and the fragile ecosystems they frequent.
Today, she maintains a dual professional identity that mirrors the complexity of the current environmental crisis. She operates as a professional climber and a specialized engineer, utilizing her platform to advocate for a more conscious approach to the outdoors. Her operate emphasizes that athletic performance does not have to exist in a vacuum, but can instead be a catalyst for ecological awareness and organizational transformation.
The Ascent to 9a+: Redefining Physical Limits
While her focus has expanded to include systemic sustainability, Berthier remains one of the most formidable climbers in the world. In 2020, she achieved a historic milestone in the discipline of outdoor climbing by becoming only the sixth woman globally to successfully climb a route graded 9a+ via The Green Shift Initiative. The specific ascent took place on the route known as “Supercrackinette” in Saint Léger.
In the grading system of rock climbing, 9a+ represents an extreme level of difficulty, requiring a combination of immense physical strength, precise technical skill, and mental fortitude. For Berthier, this achievement served as a bridge between her competitive past and her outdoor future. Moving to the south of France allowed her to rediscover the sport outside the confines of a gym, transforming climbing from a measured competition into a dialogue with the living rock.
This shift in perspective is central to her current advocacy. By moving away from the “performance-at-all-costs” mentality of indoor competition, she encourages the climbing community to rethink its relationship with the environment. She argues for a practice that is mindful of the biological impact of human presence on cliffs and the broader implications of climate change on the mountain environments that athletes rely upon.
Engineering Sustainability: The mission:possible Collective
Beyond the physical demands of the crag, Berthier applies her technical expertise as an engineer to address the structural causes of environmental degradation. She is the co-founder of mission:possible, a collective dedicated to accompanying organizations through the process of transforming their operational models toward more sustainable and regenerative frameworks via The Green Shift Initiative.
This professional pivot reflects a broader trend in the tech and engineering sectors, where specialists are increasingly moving away from traditional industrial growth models to focus on “green shifts.” For Berthier, the logic is consistent: whether she is analyzing the sequence of a 9a+ route or the inefficiency of a corporate supply chain, the goal is optimization—but the metric for success has shifted from individual victory to collective survival.
By splitting her time between professional climbing and engineering, she demonstrates a hybrid career model. This approach allows her to reach two distinct audiences: the outdoor sports community, which is directly impacted by ecological collapse, and the organizational leaders who possess the power to implement systemic change. Her work with mission:possible focuses on the practical application of sustainability, moving beyond rhetoric to assist organizations adopt models that respect planetary boundaries.
A Legacy of Competitive Excellence
Berthier’s current advocacy is grounded in a deep understanding of the competitive machinery of the sport. Her history with the Federation Française de la Montagne et de l’Escalade and her tenure with the French national team provided her with a global perspective on the sport’s growth. According to records from World Climbing, Berthier has been active in the international circuit since 2009.
Her competitive pedigree is most evident in her results within the IFSC Climbing World Cup, specifically in the “lead” discipline—a format that tests a climber’s endurance and ability to solve complex problems on a high wall. Between 2014 and 2019, Berthier was a consistent presence in major international events, including:
- Briançon, France: Multiple appearances in the World Cup, including a 14th-place finish in 2018 and a 17th-place finish in 2017.
- Chamonix, France: Consistent participation in lead and speed events, reflecting her versatility as an athlete.
- International Circuits: Competitions in Arco (Italy), Villars (Switzerland), and Kranj (Slovenia), which established her as a top-tier competitor on the world stage.
Notably, her success extended to the academic sporting arena, where she competed in the European Universities Sport Climbing Championship in Katowice, Poland, in 2015. In that event, she demonstrated exceptional range by securing a 2nd-place finish in lead and a 3rd-place finish in bouldering, highlighting the technical foundation that would later enable her 9a+ ascent.
The Intersection of Sport and Ecology
The transition from an IFSC competitor to an environmental advocate highlights a growing tension within outdoor sports. As climbing grows in popularity, the pressure on natural sites increases, often leading to erosion, disturbance of nesting birds, and the degradation of local flora. Berthier’s move to the south of France was more than a change of scenery; it was a realignment of her values.
She posits that the “performance” of an athlete should be measured not just by the grade of the route, but by the footprint left behind. This philosophy challenges the traditional narrative of “conquering” a peak or “sending” a route, suggesting instead a model of stewardship. By integrating her engineering background with her athletic visibility, she provides a blueprint for how modern athletes can leverage their influence to drive ecological transition.
The integration of these two worlds—the physical and the systemic—allows Berthier to address climate change from multiple angles. While her climbing inspires individuals to appreciate the beauty of the natural world, her work with mission:possible addresses the institutional frameworks that threaten that beauty.
Key Career Milestones
| Period/Year | Focus/Achievement | Key Detail |
|---|---|---|
| 2009–2019 | Competitive Climbing | Member of the French national team; IFSC World Cup competitor. |
| Age 24 | Strategic Pivot | Left indoor competition to focus on outdoor climbing and ecology. |
| 2020 | Elite Achievement | Became the 6th woman to climb a 9a+ (Supercrackinette). |
| Present | Dual Career | Professional climber and co-founder of mission:possible engineering collective. |
As the climbing community continues to expand, the dialogue around sustainability becomes increasingly urgent. The trajectory of Nolwen Berthier suggests that the future of the sport may lie not in the pursuit of higher grades alone, but in the ability of its practitioners to protect the environments that make the sport possible. Her journey from the structured environment of the World Cup to the unpredictable nature of the cliffs in Saint Léger serves as a powerful example of how personal growth and professional expertise can be harnessed for the greater ecological good.
For those interested in the intersection of sustainability and organizational change, the work of collectives like mission:possible offers a practical gaze at how engineering principles can be applied to environmental stewardship. As the global community faces escalating climate challenges, the synthesis of athletic discipline and scientific rigor may be exactly what is required to navigate the transition to a sustainable future.
