LEED Zero: Turning Credits Into Concrete Wins

Net-zero is no longer a buzzword, it is a score on the LEED chart that architects track as closely as fire-safety codes. LEED Zero rewards buildings that push past “less bad” and hit zero for carbon, energy, water, or waste. If your product shaves even a fraction off those impact tallies, you move up the spec sheet. Here is the playbook for manufacturers who want to ride that wave, not watch it from shore.

Secondary Data: Hidden Risk in EPD Projects

Life-cycle databases are fantastic for idea-stage modeling, but stake your final EPD on generic proxies and you invite credibility gaps, lost bids, and frantic last-minute data chases.

Non-Hazardous Waste: The Sleeper Metric in Your LCA

ISO 14025: The Passport Behind Credible EPDs

From LCA to EPD: Navigating PCRs and Verification Paths

An LCA can feel like a raw data avalanche. A Product Category Rule (PCR) funnels that data into a language the market speaks, and a verified Environmental Product Declaration (EPD) turns it into a passport that wins specs. Done right, this journey is shorter and smoother than many teams assume.
