According to a UN report from 2023, the global construction and building sector is responsible for 37% of global CO₂ emissions. In order to achieve the Paris climate targets, these emissions must be drastically reduced and carbon must be integrated into sustainable utilisation concepts in the long term. Pyrolysis is a promising negative emissions technology that not only removes carbon from the atmosphere, but also stores it permanently. Green carbon, which is obtained from biogenic raw materials through pyrolysis, offers a promising option. Its use in the construction sector could not only contribute to carbon storage, but also enable the development of innovative, ecological building materials. In Austria, however, many questions regarding availability, material properties and possible applications are still unanswered. This research project investigates the potential of green carbon in the construction sector by analysing the availability of suitable biogenic raw materials, examining the material properties of different green carbon variants and assessing their suitability for construction. In addition, detailed life cycle assessments are being drawn up to determine the environmental impact and clarify how the stored carbon can be incorporated into existing sustainability assessments. In addition, legal and normative framework conditions are being examined in order to identify regulatory gaps and necessary adjustments for the use of green carbon in the construction industry. The research and development project also focuses on LCA, building stock models, participation in the development of future scenarios for sustainable buildings/implementation of Net-Zero ( Source: https://annex89.iea-ebc.org/) The knowledge gained creates a scientific basis for the sustainable use of green carbon as an innovative building material and provides valuable impetus for future developments in Austria and Europe.   Source: https://globalabc.org/sites/default/files/2024-11/global_status_report_buildings_construction_2023.pdf
