Welcome to the Federal LCA Commons

The US Forest Service’s Forest Products Laboratory released an updated version of the Forestry and Forest Products repository. This repository contains updated forest product’s supply chain data from harvesting lumber through the processing of the lumber at sawmills. Future updates are planned this year for secondary wood products (e.g., pallets and wood flooring). This repository will eventually replace the CORRIM Forestry and Forest Products repository once all updates are completed.

The Federal Commons has released the latest version of EPA’s Tool for Reduction and Assessment of Chemicals and Other Environmental Impacts (TRACI) life cycle impact assessment method. Version 2.2 includes updated eutrophication potential characterization factors for marine and freshwater environments. The eutrophication factors are spatially explicit and can be applied to specific countries or U.S. states.

The new release is available on the Federal LCA Commons in the NREL USLCI group repository. The update in openLCA, zolca, and JSON-LD formats can also be downloaded from the USLCI GitHub Support Content Downloads page along with the associated libraries.

Argonne National Laboratory published datasets for cement and concrete production and delivery in the U.S. These datasets are based on publicly reported emissions data normalized to facility production capacity estimates.
