UL SPOT has quite a few EPDs of glass in various formats, window glass, fiberglass insulation, etc. which are in line with the interests of the building crowd. For things like fiberglass reinforcements, there’s an industry study from Europe that goes into nice detail - https://www.glassfibreeurope.eu/sustainability/life-cycle-inventory-impact-assessment/
In terms of reducing the carbon footprint, from an insulation and reinforcements point of view, some of the strategies include changing the chemical binder on insulation, increasing recycled glass cullet content, general productivity improvements & product optimization, and probably the biggest opportunity, increased use of renewable electricity, including conversion of natural gas furnaces to electric.
