Building a Greener Future: How Construction Stored Carbon (CSC) Is Reshaping Sustainable Construction

What if the buildings we live and work in didn’t just reduce their environmental impact but actively helped fight climate change? This is the promise of Construction Stored Carbon (CSC) - an innovative approach to capturing and storing carbon dioxide (CO₂) within building materials. But how does it work?

In this blog, we’ll dive into the mechanics of CSC, highlight successful projects that showcase its potential, and explore how it can assist with the fight against climate change.

What Is Construction Stored Carbon (CSC)?

CSC refers to the process of embedding CO₂ into construction materials during their manufacturing or treatment. It’s a sustainable twist: rather than releasing carbon into the atmosphere, CSC locks it away—permanently.

Here’s a simple breakdown of the process:

  • Capture: CO₂ is captured either from industrial emissions or directly from the air using technologies like Direct Air Capture (DAC), or photosynthesis as a nature-based solution.
  • Transform: The captured CO₂ is chemically bonded to construction materials. In concrete, for instance, CO₂ reacts with calcium compounds, forming a stable mineral.
  • Store: These carbon-infused materials are used in construction, sequestering the CO₂ for the lifetime of the structure.

An example of innovation in carbon management is Oncra, a pioneering organization developed by Climate Cleanup. Oncra serves as a carbon credit watchdog, ensuring the integrity of carbon removal activities within the construction sector. By developing protocols and methodologies for Construction Stored Carbon (CSC), Oncra provides a framework for quantifying, verifying, and certifying carbon sequestration in building materials. Their work ensures that carbon credits associated with CSC projects meet high standards of transparency and accountability, fostering trust and driving progress in sustainable construction.

How Does CSC Work in Practice?

Wood

Wood is central to nature-based solutions, leveraging the natural ability of trees to sequester carbon. As trees grow, they absorb and store CO₂ in their biomass, effectively acting as living carbon sinks. When sustainably harvested and used in construction, this stored carbon remains locked in for the building's lifespan, preventing its release into the atmosphere.

Engineered wood products like Cross-Laminated Timber (CLT) amplify these benefits by offering a high-strength, low-carbon alternative to traditional materials like concrete and steel. Integrating wood into construction not only reduces emissions but also supports sustainable forestry practices, creating a cycle where forests regenerate, absorb more CO₂, and provide renewable materials.

This approach embodies nature-based solutions by enhancing natural carbon cycles, restoring forest ecosystems, and promoting sustainable urban development.

Concrete

Concrete, the backbone of modern infrastructure, is also one of the largest contributors to global CO₂ emissions. The production of cement—the key binding agent in concrete—is responsible for nearly 8% of the world’s CO₂ emissions. This staggering figure highlights the urgent need for sustainable innovations in the construction industry.

Fortunately, innovative solutions are addressing concrete's environmental challenges. Carbon Stored Concrete (CSC) technologies offer a promising approach by injecting captured CO₂ into the mix, where it chemically reacts to form calcium carbonate. This process not only strengthens the material but also permanently locks away the carbon. By turning a high-emission material into a carbon store, CSC technologies pave the way for greener infrastructure, significantly reducing the environmental footprint of one of the world’s most-used construction materials.

Why CSC Matters

Buildings contribute nearly 40% of global greenhouse gas emissions, both from construction and operation. CSC offers a solution to reverse this trend.

Key Benefits:

  • Carbon Removal: CO₂ is stored in buildings for decades, potentially even centuries.
  • Durable Materials: Unique processes improve material strength and longevity.
  • Circular Economy: CSC integrates recycled materials and waste CO₂, reducing landfill dependency and industrial emissions.
  • Scalable Solutions: With advancements in material science, CSC can be applied across a wide range of projects, from residential homes to infrastructure.

Pioneering CSC Projects Across the Globe

CSC isn’t just a theoretical concept—it’s already reshaping how we build. Here are some standout examples:

  • Easy Housing, Africa
    Easy Housing integrates sustainable design with CO₂-storing materials to create affordable, climate-positive homes. Their prefabricated timber housing solution not only accelerates construction timelines but also sequesters carbon, making it a scalable and eco-friendly alternative for global housing challenges.
  • Mjøstårnet Tower, Norway
    Standing at 18 stories, this wooden skyscraper uses Cross-Laminated Timber to store carbon while showcasing cutting-edge green building design. It is a testament to how traditional materials, combined with innovative engineering, can lead to impactful carbon storage.
  • UK’s Zero Carbon Homes Initiative
    Using CO₂-storing bricks and timber, this initiative integrates CSC into affordable housing projects, proving that sustainability and cost-effectiveness can go hand in hand. It highlights how CSC technologies are being embraced for widespread, practical applications in housing developments.
