Timber as carbon dioxide removal (CDR) technology (TCCS)

Mass Timber is a natural carbon dioxide removal (CDR) technology. Let’s use it.

The importance of the construction industry, which is responsible for 40% of global CO2 emissions – and the important role that sustainably grown wood can play in reducing global CO2 emissions – is well known.

In Switzerland, there is the potential for about 1 million tons m3 of additional timber per year. (Without reducing the forest surface and with simultaneous preservation and care of our forests). In other words, the Swiss climate potential of timber construction is 1 million tons of stored CO2 per year.

We need simple, scalable CO2 tools to incentivize builders, architects, planners, forest associations, and institutions to use more wood as a building material.

We develop CO2 storage certificates for timber buildings.

CO2 storage certificates for wood buildings create environmental and financial incentives for institutional builders to use more wood as renewable building materials.

In 2021, we started to develop CO2 certificates for timber buildings, called Timber Carbon Capture & Storage (TCCS) certificates, to measure, monetize, and make tradable the long-term CO2 storage in building structures. The launch is planned for 2023.

CO2 storage certificates in timber construction are rapidly gaining importance internationally. They are cost-effective, scalable and quickly implementable (The Economist 2020) and (UNFCC Concept Note 2022).

Schematic Illustration

Illustration on the left: Conventional forest approach i.e. CO2 is stored in the forest. This temporary storage can be less and less guaranteed due to fire, beetles, etc.

Illustration on the right: Timber construction approach showing the transfer of sequestration performance and temporary CO2 storage in the forest to permanent CO2 storage in multi-storey timber construction. This is a mandatory requirement for Mass Timber to be recognized as a negative emission technology for Carbon Removal Certificate emissions.

We are a partner for decarbonization in timber construction.

We are a frontrunner in the European Built by Nature network. 

We are specialists in timber construction.

We have managed over 3,000 successful timber construction projects. Swiss timber engineering is a world leader.
