Lowering Your Carbon Footprint with Made-in-America Lighting
LED technology has dramatically improved lighting efficiency, reducing energy usage in homes, offices, warehouses, and public buildings across the country. But when it comes to environmental impact, energy savings are just one part of the equation. If your goal is to minimize your carbon footprint, then your retrofit strategy, where your lighting products are made, and how they’re made matters more than you might think.
How Retrofit Practices Have Evolved
From the 1980s through the early 2000s, lighting upgrades in existing buildings primarily relied on “retrofitting”. This approach involved replacing only certain components, such as incandescent and Halogen bulbs as well as fluorescent and HID lamps and ballasts, all while keeping the original fixture housing intact. Waste like worn out plastics was recycled, and hazardous materials like mercury or PCBs were managed through environmental services, leaving minimal waste generated. This method offered a relatively low-carbon, low-waste way to improve lighting efficiency.
But at the launch of LED, large fixture manufacturers not accustomed to the retrofit market launched full LED fixture replacements where retrofits had previously been the go to strategy. This strategy required discarding entire fixtures to achieve a newer appearance, which significantly increased the carbon footprint.
By 2010, full fixture replacements became the norm, with a small amount doing full door frame replacements for aesthetic upgrades but still generating more waste than a standard retrofit. As a result, large quantities of steel and plastic were discarded, leading to higher environmental costs due to both the materials themselves and the transportation and disposal required.
The Hidden Carbon Cost of Overseas Manufacturing
The process of manufacturing and transporting a lighting fixture across the globe involves a surprising amount of carbon. First, there are the emissions from the manufacturing process itself in overseas locations that do not have EPA-like bodies restricting waste from factories. In the United States, factories must comply with EPA regulations for air quality, wastewater discharge, paint application, and material sourcing. For example, powder coating in the U.S. must meet specific environmental standards [1], and steel production is subject to emissions limits [2]. That is not the case in many overseas factories, where paints may be solvent-based and emissions controls are minimal or nonexistent [3].
Then there is the shipping. A fixture manufactured overseas may travel thousands of miles by cargo ship, rail, and truck before it arrives at a U.S. job site. That journey adds layers of carbon output, especially when compared to sourcing lighting from a domestic manufacturer located just a few hundred miles from the project site.
And the impact doesn’t end there. A manufacturer supplying the entire U.S. from a single foreign facility must rely on an expansive distribution network. That means lighting products are trucked coast to coast, adding even more transportation-related emissions. In contrast, regional U.S. manufacturers can deliver within tighter geographic ranges, significantly reducing fuel use and carbon emissions.
What Makes U.S.-Made Lighting More Sustainable
Lighting products manufactured in the United States benefit from cleaner processes at every stage. Here are just a few examples:
- Steel and aluminum sourcing: U.S. steel is produced under strict environmental controls. Domestic mills often use electric arc furnaces powered by cleaner energy sources, and scrap recycling is a core part of the process.
- Paint and finish: Powder-coated finishes used by American manufacturers meet EPA standards, with rigorous controls on air quality and overspray capture. Overseas factories often use dip or spray methods without proper containment, releasing volatile organic compounds (VOCs) into the air.
- Plastics manufacturing: In the U.S., plastics used in lighting are subject to filtration and water-treatment requirements. Machinery used for extruding or thermoforming components must cool water and treat it before it re-enters the environment. In many foreign facilities, that water is discharged untreated.
- Shorter supply chains: Products made close to where they are installed require far less transportation, which reduces emissions from fuel and logistics [4].
Why It Matters
If you’re aiming for LEED certification [5], working toward ESG goals, or simply trying to make more environmentally responsible decisions, the choice to buy American-made lighting can have a measurable impact. A fixture built in the U.S. does more than lower the carbon footprint of the lighting itself. It also reduces the carbon footprint of your entire project. Working with carbon auditors [6] and carbon credit organizations [7] can bring new layers of government support, incentive money, and market awareness to your carbon practices vs. your competition. Chief Sustainability Officers (CSOs) are taking more aggressive measures to align with contractors, specifiers, and manufacturers who have proven, auditable carbon footprints, and choose these vendors over their larger carbon footprint competitors every day.
The Bottom Line
Sustainability is not just about using less energy once a product is installed. It is about making smarter decisions across the full lifecycle of that product, from material sourcing to manufacturing to delivery. If you’re serious about lowering your carbon footprint, ask where your lighting was made, how it was made, and how far it had to travel. In most cases, the greenest option is the one that is built closer to home.
