…and certified timber!

Embodied Carbon also varies by building type:

So, what can we do?

Architecture firms are asked to recognize the “interlinked crises of climate breakdown, biodiversity loss, and societal inequity” and commit to several actions, including:1) performing life-cycle costing, whole-life carbon modeling, and post-occupancy evaluation within their basic scope of work2) upgrading existing buildings rather than building new whenever viableemploying just labor practices and 3) ensuring that all climate mitigation and adaptation efforts address the needs of disadvantaged people
