Quoted from the 4.1 Beta:
Option 2. Multi-Attribute Optimization (1 point)
Use products that comply with one of the criteria below for 10%, by cost, of the total value of
permanently installed products in the project, or use at least 10 permanently installed products sourced
from at least three different manufacturers. Products will be valued as below.

Life Cycle Impact Reductions in Embodied Carbon.
Products that have demonstrated environmental impact reductions for the specified functional unit
based on a current third-party EPD or verified LCA that conforms to the comparability requirements
of ISO 14025 and ISO 21930.
The comparative analysis must show impact reduction in the global warming potential (GWP)
impact category and must include a narrative describing how reductions in impacts were
achieved. The published comparisons must be third-party verified (value at 100% by cost or 1
product).
The comparative analysis must show impact reduction(s) of at least 10% in the global warming
potential (GWP) impact category and must include a narrative describing how the impact
reductions were achieved. The published comparisons must be third-party verified (value at
150% by cost or 1.5 products).
The comparative analysis must show impact reduction(s) of at least 20% in the global warming
potential (GWP) impact category, and demonstrate at least 5% reduction in two additional
impact categories. A narrative describing how the impact reductions were achieved is required.
The published comparisons must be third-party verified (value at 200% by cost or 2 products).
The reductions described above are reductions when comparing a new version of the product from the same manufacturer? Or are those reductions comparisons between the product and the industry in general?

From what I've read on the UL website, which is one of the third parties that verifies EPD and LCA's, the reductions can calculated by comparing a product-specific EPD and an industry-average EPD, or they can also be from comparing a newer product-specific EPD and an earlier published EPD for the same product.
