Life Cycle Assessment of Carbon Dioxide Removal options

Together with the Technology Assessment group at the Paul Scherrer Institute (PSI), we work on evaluating different carbon dioxide removal (CDR) methods. The project is funded by the Swiss Federal Office for the Environment (FOEN).

Within the project, the Technology Assessment group develops life cycle analyses and inventories for direct air carbon capture and storage (DACCS), bioenergy carbon capture and storage (BECCS), enhanced weathering (EW), biochar and wood in construction. Together we parametrize the LCAs for these methods and develop a public LCA screening tool that can be used to identify hotspots and gather early insights.

Additionally, we evaluate the certification schemes that are used to certify that carbon has been removed. We have developed criteria that these certification schemes should satisfy and evaluate the methodologies that set out the requirements for certification based on these criteria.
