Wood naturally sequesters Carbon.............concrete & steel do not


Ontario sets new greenhouse gas pollution reduction target so why does choosing Guardian's product matter?

Wood is one of the most environmentally responsible raw materials because its renewable and stores carbon.  In fact 50% of the dry weight of wood is carbon and its use substitutes more carbon intensive materials like steel and concrete. Carbon remains locked in the wood for the life of the product. The core of our bridge deck is made of wood so its a carbon neutral product.


Target sends 'clear signal' that Ontario is committed to reducing greenhouse emissions

On May 14, 2015,  the Ministry of the Environment and Climate Change said it was committing to a new mid-term target to reduce emissions by 37 per cent below 1990 levels by 2030. 

If your communityhas committed to reducing greenhouse emissions and truly wants to reduce your carbon footprint, then consider the alternative to conventional concrete and steel.  Wood has come a long way, Engineers and Architects are upgrading  their knowledge on value added wood products, and learning about new ways to implement them.  


Why?...the Ministry of the Environment and Climate Change said

"Climate change is already hurting our environment, causing extreme weather like floods and droughts, and hurting our ability to grow food in some regions," the Ministry of the Environment and Climate Change said in a statement.

"Over the near term, it will increase the cost of food and insurance, harm wildlife and nature, and eventually make the world inhospitable for our children and grandchildren."

Earlier this year, the province announced a cap-and-trade system for carbon emissions.

Guardian manufactures fiberglass wood composite products that

  • greatly reduce greenhouse gas emissions in comparison to steel and concrete,
  • naturally sequester large amounts of greenhouse gas emissions in comparison to steel and concrete,
  • performance equivalent to steel and concrete,
  • stamped by third party engineers conforming to codes,
  • fiscally responsible as it does not cost more at bidders price,
  • a benefit under the proposed cap and trade system for carbon emissions



Everything we do affects the environment around us. It is impossible to construct a building or a bridge without having some impact on the world’s environment. Designers and builders are becoming more aware that the selection of materials, building systems and equipment can reduce the effect of construction on the world around us.




Designers and building owners in North America and elsewhere are embracing the concept of "Green" and are making choices that reduce energy use, reduce the use of non-renewable materials, and reduce the pollution caused by the manufacture of materials. In this way, they are able to minimize the impact or “environmental footprint” of a structure.

As designers, purchasers, owners make conscious environmental choices, they are returning to the only building material that uses the sun’s energy to renew itself in a continuous sustainable cycle – wood. Wood is the only major building material that is renewable.

 Warm, natural wood uses less energy and produces less air and water pollution than the energy intensive manufacture of steel and concrete.



In addition, new technology is producing engineered wood systems that maximize the use of the material to reduce resource use. In looking at the scientific evidence, wood clearly makes the grade as the green material of choice.


Carbon cycle: A process related to the constant exchange of carbon between different sources. Carbon sinks are elements in the carbon cycle that are able to capture carbon dioxide and reduce its concentration in the atmosphere. Forests are a carbon sink—they take in carbon dioxide and convert it to wood, leaves and roots. They are also a carbon source—they release stored carbon into the atmosphere when they decompose or burn.DEFINITIONS


Carbon sequestration: The ability of forests or other natural systems to “sink” or store carbon, thereby preventing it from collecting in the atmosphere as carbon dioxide. Forests absorb carbon when they break down carbon dioxide during photosynthesis. 


Deforestation: Permanent conversion to non-forest uses such as agriculture or urban development.


Embodied energy: All of the energy, direct and indirect, required through the life of a product, from extraction to disposal.


Green Structure: Choosing products and building designs that make structures more resource efficient and reduce their impact on human health and the environment through location, construction, operation, repair and maintenance, and renovation, and final deconstruction, demolition, or removal.


Life cycle assessment (LCA): A science-based process that examines the potential environmental impact throughout the life of a given product or service—from resource extraction through to product manufacturing, operation and use, and eventual reuse or disposal. It is frequently used to assess bridge or building products and assemblies. 


Sustainable forest management: Management that maintains and enhances the long-term health of forest ecosystems for the benefit of all living things while providing environmental, economic, social and cultural opportunities for present and future generations.
