natureplus Symposium „Carbon Capture and Storage for free?”

During this natureplus symposium on October 12th (14:00-17:00 CEST), we’ll discuss how tools and legislation are evolving to recognise sequestration, and how policy is being enacted to encourage the uptake of more bio-based materials.

In November 2021, the spotlight will be on Glasgow for the 26th UN Climate Change Conference (COP26). Will the world’s leaders be able to accelerate their efforts we so urgently need to achieve the climate targets agreed upon in Paris in 2015?

The role of the construction industry in contributing to climate change must not be underestimated, with the building and construction sector contributing 38% (9.95 Gt CO2) of global CO2 emissions in 2019.[1] In order to leverage the sector’s huge carbon reduction potential, we must go further than just improving the operational energy efficiency of buildings and focus on reducing the environmental impacts of building materials, from extraction and manufacture through to end-of-life.

Emissions from the production of building materials are largely driven by cement and steel manufacturing, and their growth in use is a major driver of building related embodied carbon emissions. However, there are readily available alternatives, such as bio-based materials, which not only have lower embodied carbon but capture carbon from the atmosphere during their growth.

This carbon is stored or ‘sequestered’ over the life or the product and/or the lifetime of the building. The amount of stored carbon is relatively easy to calculate but the current life cycle analysis (LCA) methodology under EN 15804+A2 decrees that the sequestered carbon number should be stated separately to the embodied carbon. LCA assumes that this stored carbon is then lost back to the atmosphere at end of life when the material is generally burnt or landfilled.

However, if we are to meet the world’s climate goals and limit global warming to well below 2 degrees, we must concentrate on reducing CO2 emissions NOW, rather than in 10-30 years or at the end of a building’s lifecycle. This temporary storage of carbon within a product is an effective and ‘free’ method for capturing carbon from the atmosphere and so should be appropriately recognised by tool providers and legislators.

This symposium will be the opening for a ten days natureplus Europe Event Series 2021 titled “How to Build Climate Protection”. For the symposium and the other events of the series you can register here.

This event series is generously supported by our sponsors Baufritz & GUTEX.
