Glasgow’s COP26 Timber Monuments and Low-Carbon Legacy

Beacon of Hope: Glasgow’s Mass Timber Monuments at COP26

As the world’s attention converged on Glasgow for the COP26 UN Climate Change Conference, a series of compelling art installations and timber monuments took center stage. These structures were more than striking visual statements: they embodied urgent calls for climate action, showcased sustainable material innovation, and ignited public conversation about our shared environmental future.

Why Monuments? The Power of Symbol in the Climate Conversation

Monuments and public art have long played a role in communicating shared values and aspirations. At COP26, three distinct monuments—each drawing from Scotland’s material heritage and creative energy—became rallying points and educational prompts. They acted as both beacons of hope and urgent calls to action, making visible the possibilities of sustainable construction and community legacy.

• Beacon of Hope: A mass timber installation at Glasgow Central Station.
• The Hope Sculpture: A monumental, low-carbon concrete artwork at Cuningar Loop Park.
• Rottenrow Gardens Figures: Colorful steel and concrete sculptures on the University of Strathclyde’s campus.

The Beacon of Hope: Central Station’s Timber Landmark

Foremost among the COP26 installations, the Beacon of Hope stood in Glasgow Central Station, encountered by over 15 million annual passengers. Conceived and built by a collaboration led by BE-ST, Steuart Padwick, Natalie Alexopoulos, and Ramboll, this project unified the efforts of more than 50 companies committed to sustainability and climate communication. Its design and materials made a statement on resource stewardship and innovation for a net-zero future.

Design Features and Inspiration

• Materiality: Contoured layers of FSC-certified, Scottish-grown Sitka Spruce—the product of Scottish forestry innovation and the Transforming Timber project.
• Form and Message: The monument’s form evoked natural growth and renewal, serving as a literal and figurative beacon of sustainable hope and technological progress in timber construction.
• Public Engagement: Intriguing displays and digital content encouraged visitors to engage physically and intellectually, connecting the tactile qualities of wood to the story of climate action.

This installation demonstrated over 70% reduction in embodied carbon compared to conventional structures by using reclaimed, recycled, or low-carbon materials, almost all sourced locally.

The Mass Timber Movement: Why Timber Matters

The Beacon of Hope was not an isolated symbol but the centerpiece of a larger campaign to spotlight timber’s role in sustainable construction. Timber, when responsibly sourced and engineered, offers unique advantages in the fight against climate change:

• Carbon Sequestration: Trees naturally absorb and store atmospheric carbon, and wood products maintain locked-in carbon throughout their lifespan.
• Low Embodied Carbon: Engineered mass timber components require less energy to produce than steel or concrete, dramatically lowering their carbon footprint.
• Renewability: Unlike finite materials, timber can be regrown and sustainably managed, creating an ongoing cycle of climate benefit.

COP26 brought together architects, engineers, environmentalists, and policymakers to champion the broader adoption of timber for large-scale construction. The conference’s “Wood for Good” events and interactive city map allowed visitors to explore not only new monuments but also exemplary timber buildings throughout Glasgow.

Collaborative Innovation

Among many collaborative initiatives was the Timber Beacon proposal by dRMM architects, which explored timber’s carbon, strength, and beauty as a construction material. More than 25 innovators from across Europe contributed, including major timber trade federations. The project reimagined timber’s potential as a solution for decarbonizing construction and renovation, advocating for globally scalable, nature-based building systems.

The Hope Sculpture: Legacy and Craft in Cuningar Loop Park

The Hope Sculpture offered a stark visual reminder of the city’s industrial history and its transition towards sustainability. Rising 20 meters above Clyde Gateway’s Cuningar Loop, it evoked the brick chimney stacks that once dominated Glasgow’s landscape—but with a critical difference: it was built from revolutionary, low-carbon materials.

• Innovative Concrete: Constructed from a 100% cement-free concrete blend, utilizing locally sourced aggregates and recycled crushed glass. This cutting-edge formulation reduced the carbon impact by more than 70% compared to standard concrete.
• Sculptural Details: The top features a child figure—neutral in gender, age, and race—extending a hand toward a more hopeful, sustainable tomorrow, crafted from the same eco-friendly concrete and glass.
• Hidden Sustainability: Structural supports included reclaimed steel gas pipes and recycled rebar, further minimizing embodied carbon and maximizing the re-use of local industrial resources.

The Hope Sculpture was installed as both a gift to Glasgow and a physical legacy of COP26—a permanent space for community reflection and pride.

The University of Strathclyde’s Colorful Figures: Unity and Reclamation

The third monument in this triad stood at the University of Strathclyde’s Rottenrow Gardens. This installation comprised three vivid, expressive figures, representing the power and necessity of coming together to meet global challenges. Sustainability was again central:

• Materials Used: Reclaimed sheet steel for the figures and low-carbon, cement-free concrete for the foundations.
• Symbolism: The figures’ openness and embrace signified inclusivity and hope, underscoring the collaborative spirit required to achieve a net-zero future.

Timber’s Role at COP26: From Symbolism to Systems Change

Timber was theme woven throughout COP26, permeating installations, conferences, and exhibits:

• The Wood for Good conference highlighted innovations in timber construction, featuring experts like Andrew Waugh (Waugh Thistleton), and panels on growing zero-carbon communities, engineering timber, and managing sustainable forests.
• The Build Better Now virtual exhibition, sponsored by Wood for Good and the UK Green Building Council, showcased cutting-edge sustainable building projects, including mass timber developments around the world.
• An interactive map guided COP26 visitors to key timber structures across Glasgow, from the new installations to reimagined landmarks like the Theatre Royal and community timber housing estates.

Together, these efforts sought to mainstream timber as a viable, desirable alternative to carbon-intensive materials in both new construction and renovation projects—demonstrating practical, scalable pathways toward decarbonized cities.

dRMM’s Timber Beacon Pavilion: A Traveling Manifesto

Notably, dRMM architects’ “Timber Beacon” was envisioned as a demountable, reusable pavilion—symbolically bringing hope from COP26 in Glasgow to other European cities, including a stop at the EU Parliament to influence policy. Its three core elements each extolled a virtue of modern timber engineering:

• The tower demonstrated the feasibility of building tall with wood.
• The canopy showcased timber’s impressive structural capacity.
• The exhibition room highlighted adaptability and hosted interactive educational displays.

Visitors were encouraged to touch, explore, and learn—making tangible the potential for wood and forests to “avert catastrophic climate change,” as dRMM’s Alex de Rijke noted.
