L.A. Green Building Code: Embodied Carbon Rules You Can’t Ignore

Los Angeles just strapped a booster pack onto California’s already-tough CALGreen code. Starting July 1 2024, big projects must cap the global-warming potential of concrete, with steel and glass right behind. If your product ships without a bullet-proof, facility-specific EPD, specifiers may swipe left.

Virginia’s Asphalt-Recycling Tax Credit, Decoded

Virginia lawmakers flirted with a 20 percent income-tax credit for buying asphalt-recycling equipment. House Bill 2740 stalled in February 2025, yet its core ideas keep resurfacing in Richmond and in copy-cat bills elsewhere. If you make or lay asphalt, here is why the proposal still matters for your plant ledger, your EPD numbers, and your sales pipeline.

Austin Greenlights Hempcrete—Code Change, EPD Opportunity

On July 10 2025, Austin becomes the first major U.S. city to fold Appendix BL of the 2024 International Residential Code into law. That one vote swaps “alternative material” red tape for a straight-up permit path for hemp-lime walls. If you sell hemp shives, lime binders, or pre-cast blocks, the clock just started ticking on your environmental paperwork.

New York’s A8202/S8000: the next Buy-Clean wake-up

A bill now moving through Albany would turn New York’s current “please disclose” embodied-carbon guidance into a binding requirement starting January 1 2026. If your concrete, asphalt, or steel ships to a state-funded job without a product-specific EPD, the bid may never even open. Tick-tock.

Embodied Carbon Crashes the 2027 IECC-R Party

Two freshly filed code proposals—RE196-24 and RE137-24—aim to drag embodied carbon from the footnotes of voluntary standards into the body of America’s next residential energy code. If they pass, every two-by-four, insulation board, and window frame will sit under the same carbon microscope as HVAC loads. Manufacturers that show up with airtight EPD data will win specs while laggards scramble.

Buy Clean Massachusetts: Embodied-carbon rulebook

Beacon Hill is weighing HD.3507, a bill that would turn embodied-carbon data into a ticket of entry for public contracts. If you sell concrete, steel, rebar, or engineered wood in Massachusetts, the countdown to verifiable Environmental Product Declarations (EPDs) could start the moment the bill clears committee.

Zero-Carbon Renovation Fund: New Gold Rush for Low-Carbon Materials

Massachusetts wants to pour $300 million into making old buildings all-electric, energy-tight, and built back with low-embodied-carbon components. If you manufacture concrete mixes, insulation, panels, or fixtures, HD.3171 could steer a torrent of public money toward products that prove their climate math. That proof almost always means a rock-solid EPD.

FDES XML Standard in France: Quickfire Guide

Bidding on a French building project without an FDES feels like showing up at Cannes without a film. The Environmental and Health Declaration Form is the ticket to enter France’s RE2020 market, a scene now worth an estimated €35 billion a year (CSTB, 2024). Skip it and your product may never reach the screening room.

INIES: France’s Essential EPD Hub

Stichting MRPI: Dutch EPD Fast Track

Selling into the Netherlands without an MRPI-registered EPD is like showing up to a speed-dating event without a name tag—you’ll be invisible long before you can pitch performance claims. Dutch building codes, public tenders, and most big contractors now pull environmental scores straight from the Nationale Milieudatabase (NMD). Only EPDs vetted by Stichting MRPI slide into that database automatically, which means your product lands on the shortlist while competitors wait at the gate.

BRE Global: Should You Publish Your EPD Here?

For UK-focused manufacturers, BRE Global looks like the obvious EPD gatekeeper. Its name shows up in BREEAM manuals, BIM libraries, and spec sheets from Manchester to Melbourne. Yet size, rules, and service model matter when you are racing to hit a tender deadline. Here is the operator’s real footprint and how it compares.

SCS Global Services: What to Know Before Publishing

Choosing an EPD program operator can feel like picking a phone plan: hidden fees, patchy coverage, and long lock-in periods lurk in the fine print. SCS Global Services promises broad recognition, a hands-on LCA team, and ANSI-backed credibility—but the path from data pull to public declaration still holds surprises for busy manufacturers.

PAS 2080: Your Ticket to UK Low-Carbon Infrastructure

Tender documents across the UK now slip a quiet question into the technical specs: “Show evidence you comply with PAS 2080.” Skip it and your bid can vanish before price talks even start. The 2023 revision sharpened rules on embodied carbon, built a bridge to EN 15804-based EPDs, and set a ticking clock—owners can reject data older than two years. Manufacturers that master the paperwork will ride a procurement tailwind; the rest face extra site visits and awkward clarifications.

EPDs: A Marketer’s Secret Weapon

Your product may boast flawless performance, but if the specifier cannot see a credible environmental score next to it, you are out of the running before the first call. Environmental Product Declarations (EPDs) turn invisible supply-chain data into a story architects can cite and purchasing teams can trust.

HPDs & EPDs: Same Data, Different Payoff

Still confusing Health Product Declarations with Environmental Product Declarations? You are not alone. They serve different audiences, yet most of the raw process data you gathered for an LCA or EPD can power an HPD too, turning one transparency project into two and unlocking more rating-system points (LEED, BREEAM, WELL) with near-zero extra headache.

Environmental Product Declarations: Why They Matter Now

A single missing EPD can boot your product from a bid faster than a grumpy bouncer. Yet manufacturers still treat declarations as optional paperwork. With new rating systems, data-hungry specifiers, and carbon math on every tender, skipping an EPD in 2025 is like launching a phone without a camera—possible, but painfully uncompetitive.

Health Product Declarations: Counting the Payback

The ask seems simple: create a Health Product Declaration and move on. Yet many manufacturers hesitate, worried about cost, data hunting, and the infamous "round two" of ingredient questions. Here is why that hesitation leaves money on the table.

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.

EPD First, HPD Fast: Double ROI, Half Effort

Collecting cradle-to-gate numbers for an EPD feels like herding every invoice, utility bill, and transport ticket your plant has printed in a year. The good news: once that spreadsheet is tamed, ninety percent of what a Health Product Declaration asks for is already in your files. Turning one disclosure into two is a quick extra lap that multiplies bid-day advantages without multiplying headaches.

Pick the Right PCR, Win the Bid

Grab the wrong Product Category Rule and your Environmental Product Declaration can stall six months, miss a bid date, or fail verification outright. The right PCR, in contrast, clears a straight runway for life-cycle modeling, third-party review, and faster market access. Here is how manufacturers zero in on the rulebook that fits their product, region, and timeline.

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. The smartest manufacturers swap proxy shortcuts for laser-targeted primary data, without burying their engineering teams in spreadsheets. Here’s why.

Non-Hazardous Waste: The Sleeper Metric in Your LCA

Carbon steals the spotlight, yet every EPD still prints a boldfaced line for “non-hazardous waste disposed.” Mess up that line and specifiers will question the rest of your data. Here is how to nail the number and even trim it before the LCA clock starts ticking.

Module D: Your EPD’s Second Life Credit
