DF 80 – Biogenic carbon and climate change mitigation: silver bullet or flash in the pan?
Renewable feedstocks and their biogenic carbon are one of the key elements of greenhouse gas emission policies towards net zero. However, today various approaches exist to model flows and related climate change impacts of biogenic carbon and biogenic CO2, including disputed approa¬ches and regulations which attribute reduced Global Warming Potentials for late CO2 emissions.
Companies are starting to compensate their fossil-based CO2 emissions caused in manufacturing with reforestation projects. Others sell their fossil CO2 emission reductions achieved by switch¬ing to renewable materials as emission certificates to third parties. And again others claim re¬duced CO2 emissions of their products compared to current standard products (handprints).
This LCA forum will provide a synopsis on the various approaches and facets of modelling bioge¬nic carbon and biogenic CO2 in the building and construction sector and offers a discussion plat¬form for resolving or better understand the positions and arguments related to contentious issues. It is supposed to foster harmonisation and, where not achievable, at least to contribute to increase transparency.
A Keynote speech of Dr. Cyril Brunner, Climate Physics group, ETH Zürich, will set the floor for an informative and comprehensive 80th LCA forum on biogenic carbon assessment and climate mitigation in the construction sector.
A nice overview and summary of the event can be found in Buildings & Cities from September 16th 2022.
