TL;DR: This case study demonstrates that the use of global warming potentials for a given time horizon to characterize greenhouse gas emissions leads to an inconsistency between the time frame chosen for the analysis and the time period covered by the LCA results.

TL;DR: In this article, the authors have developed robust methods to account for the benefits, if any, of sequestration and temporary storage and release of biogenic carbon, but there is still no overall consensus on the most appropriate ways of considering and quantifying it.

TL;DR: Sala et al. as discussed by the authors proposed a midpoint-damage framework with four distinct complementary viewpoints to present an LCIA profile: (1) midpoint impacts, (2) damage impacts,(3) damages on human health, ecosystem quality, and resources & ecosystem service areas of protection, and (4) damaging on water and carbon areas of concerns.

TL;DR: In this article, the authors show the importance of consistent consideration of biogenic carbon and timing of GHG emissions in life cycle assessment (LCA) and carbon footprint analysis and use a case study assessing the life cycle of a wooden chair for four end-of-life scenarios to compare different approaches: traditional LCA with and without consideration of Biogenic carbon, the PAS 2050 and ILCD Handbook methods, and a dynamic LCA approach.

TL;DR: In this article, the authors investigated known challenges related to buildings LCA such as biogenic carbon accounting and dynamic and prospective aspects, and discussed how they affect LCA results for low energy buildings and what developments are still needed.
