embodied carbon of timber

Timber is a naturally renewable, low embodied carbon material and removing the need to transport it from abroad could cut its carbon footprint even further. Solar panels on the roof produce renewable energy that, combined with the timber structure, compensates for the building’s CO 2 emissions. Wood stores carbon and, with the least embodied energy of all major building materials, requires less energy throughout its life cycle. Embodied carbon refers to all the carbon produced during the product’s life – which isn’t always easy to determine. Study Shows Why We Need 1.5 Degree Lifestyles and How to Get There .

In the absence of a comprehensive global embodied energy public dynamic database, embodied energy calculations may omit important data on, for example, the rural road/highway construction and maintenance needed to move a product, marketing, advertising, catering services, non-human services and the like. Because the wood stores carbon dioxide (CO 2 ) that was captured from the atmosphere via photosynthesis, mass timber construction can function as a form of carbon removal when combined with sustainable timber production and building demolition practices. Yet there is much uncertainty about how to reduce embodied carbon. In the Earth’s atmosphere, carbon dioxide exists at a concentration of around 0.04% (400 ppm) by volume. Sustainability leader Sarah King explains how developers and contractors can use the new EC3 software tool to reduce embodied carbon in their buildings. [20], Although most of the focus for improving energy efficiency in buildings has been on their operational emissions, it is estimated that about 30% of all energy consumed throughout the lifetime of a building can be in its embodied energy (this percentage varies based on factors such as age of building, climate, and materials). The SBTool, UK Code for Sustainable Homes was, and USA LEED still is, a method in which the embodied energy of a product or material is rated, along with other factors, to assess a building's environmental impact.
