We are really “getting in the weeds” here, but what you you are describing below is indeed similar to LEEDS described “carbon sequestration”.  They are both a new paradigm or way of thinking about costs and values.  Both are new ways of measuring embedded or intrinsic physical or social values that are not normally measured.

For Example:

Embodied carbon and sequestration in our Pier 5 restoration relates to the fact that carbons become “embodied” in existing built structures and that value can be preserved by maintaining the structures that embody or sequester (capture and store) large amounts of carbon ––like Pier 5.

So, with Pier 5, all aspects of the steel present in the pier have varied accumulations of carbon that was used to: mine, transport, manufacture, transport, erection and construction activities, etc.  All of this captured carbon currently in place can be given a value in a LEEDS certified form of construction cost estimating.  

This carbon equivalency can radically change cost estimates when used in these calculations.  It would be a game changer for any Pier 5 restoration vs demolition evaluations and cost/benefits.
