Reducing your carbon footprint is the process of cutting the greenhouse gas emissions your business is responsible for, and one of the simplest, most cost-effective ways to do that is by upgrading your lighting to modern LED systems.
In this article, we’ll look at why lighting is such a big piece of the carbon puzzle, how LED lighting can cut your emissions by 50–90% while saving you money, what makes LEDs cleaner and safer than older technologies, how they fit into a broader sustainability strategy (alongside options like wind and solar), and how Relumination helps commercial and industrial companies turn “going green” into a very practical business decision.
By the end, you’ll see that saving money and saving the environment often go hand in hand—and that lighting is one of the best places to start.
What Is a Carbon Footprint—and Why Should Businesses Care?
Just in case you’re unaware, the world’s carbon footprint is measured by analyzing the amount of greenhouse gases present in the Earth’s atmosphere. They are an amalgamation of various gases, including hydrofluorocarbons, methane, carbon dioxide, and nitrous oxide.
Collectively, they are generated during our use and subsequent disposal of services and goods. Electricity and the items generated understandably fall into those two categories.
In 2024, it was revealed that the world’s carbon footprint was an eye-popping 31.6 gigatonnes. When announcing that number, the International Energy Agency made several suggestions for how it could be reduced.
One of them was increasing the world’s use of eco-friendly lighting systems like LEDs.
As a business owner, you occupy a unique position when it comes to reducing your carbon footprint. Not only can this help save the environment, but it will also save you money. Regardless of your business’s size, improving energy savings is a valuable investment, both for your company’s competitiveness and for the planet.
Relumination exists to help companies make that investment in a way that’s technically sound, financially smart, and easy to implement.
Why Lighting Is a Big Piece of the Carbon Puzzle
Lighting is responsible for a large amount of unnecessary wasted energy and for releasing the potent greenhouse gas carbon dioxide into the atmosphere.
According to the U.S. Energy Information Administration, in 2011 about 461 billion kilowatt-hours (kWh) of electricity were used for lighting by the residential and commercial sectors. This was about 17% of the total electricity consumed by both sectors and about 12% of total U.S. electricity consumption.
That means even modest improvements in lighting efficiency translate directly into big energy and emissions savings at scale.
Many people have already chosen to switch from incandescent to fluorescent lighting, but fluoroscents have a number of disadvantages:
- Lower efficiency than LEDs – they still waste a significant portion of energy as heat.
- Toxic materials – each fluorescent light bulb contains about 5 milligrams of mercury, a potent neurotoxin that can cause brain and kidney damage. It’s enough to contaminate approximately 3,000 gallons of drinking water.
- Disposal challenges – when the light bulbs burn out, the average consumer will often throw the bulb away in the trash, creating a risk to your business, your employees, and the environment.
Lighting is clearly a large and visible contributor to your energy bill and carbon footprint—and that’s exactly why it’s such a powerful lever for change.
Why LED Lighting Is an Effective Path to a Reduced Carbon Footprint?
Regardless of whether an enterprise uses fluorescent, incandescent, sodium, or metal halide lighting—or some combination thereof—a switch to LED lighting offers obvious benefits.
Commercial LED lighting is 50–90% more efficient than traditional lighting, depending on the application. In some projects, energy usage can be reduced as much as 90 percent.
LEDs:
- Use far less electricity for the same (or better) light levels
- Last dramatically longer than older technologies
- Contain no mercury or fragile glass tubes
- Run cooler, which reduces air conditioning loads
- Can be controlled, dimmed, and automated in ways older systems can’t
A transition to LED (Light Emitting Diode) lighting is one of the most effective sustainability steps that any business can undertake. The ratio of dollars invested to carbon reduced is often better with LED lighting than with most other efforts to shrink a company’s carbon footprint.
So much so that for many of our clients, upgrading to LED is not just an environmental initiative—it’s a core cost saving and operational improvement strategy.
What are the The Environmental and Financial Benefits of LEDs
Let’s break down exactly how LED lighting helps you reduce your carbon footprint while strengthening your bottom line.
Massive Energy Savings and Lower Utility Bills
LED lighting is 50–90% more efficient than conventional bulbs. LED lights use half as much energy as conventional lighting—or only a tenth of the amount in some cases. This translates directly to a 50–90% saving on your energy expenditures.
From another one of our articles:
LED lights are as much as 90% more efficient than conventional lighting. This means you’re looking at up to 90% savings on your utility bills.
A high-profile example: Delta Airlines announced they’re committed to upgrading their entire fleet to LED lighting over the course of three years, in a move that’s estimated to save as much as $50,000 per plane, per year.
You don’t have to be an international air carrier to see that kind of value, of course. Even small and mid-sized facilities see substantial savings as soon as the new lighting is turned on.
Every kilowatt-hour you don’t use:
- Reduces your operating costs
- Reduces the total power that needs to be generated
- Reduces the associated greenhouse gas emissions from that power
Saving money and saving the environment often go hand in hand.
Longer Life, Less Maintenance, and Less Waste
LED lights also last far longer than older technologies.
- Many LED systems last five times longer than conventional lighting.
- In some industrial applications, LED systems last up to 15x longer than HID or fluorescent lamps, delivering tens of thousands of hours of reliable use.
Think about how annoying (and expensive) it is when a light bulb burns out. You’re not only paying for the replacement lamp, but also:
- The labor and time to fix it
- Lifts, ladders, or other equipment to reach fixtures
- Downtime or disruption in the area affected
With LEDs, those headaches go away for years at a time. This “fit-and-forget” level of reliability means fewer replacements, less waste headed to landfills, and less carbon emitted manufacturing and transporting replacement bulbs and components.
Cooler Operation and Reduced HVAC Loads
Conventional lighting generates a lot of heat, as anyone who’s changed a light bulb will tell you. That wasted heat:
- Makes spaces less comfortable
- Forces air conditioning and ventilation systems to work harder
- Adds directly to your energy use and emissions
LED lights, on the other hand, waste less than 10% of their energy as heat. Because of their better energy efficiency and low operating temperature, they:
- Put less strain on your AC, especially in hot climates or in industrial applications
- Improve comfort for employees and customers
- Reduce the risk of contact burns if someone touches a fixture
Again, this means further savings on your energy bills and your carbon footprint.
Non-Toxic, Low-Pollution Technology
Unlike fluorescents, LEDs are non-toxic. LED lighting:
- Contains no mercury, so there’s no risk of contaminating thousands of gallons of water if a lamp breaks or is improperly disposed of
- Does not emit harmful radiation such as infrared (IR) and ultraviolet (UV)
- Generates far less heat, reducing the risk of heat-related damage to surroundings
In addition to being carbon-footprint-friendly and recyclable, LEDs’ extended use also helps minimize light, soil, and water pollution.
Their small, compact profile and durable design—no thin glass tubes—make them extremely safe for tight spaces, food prep areas, or clean rooms where breakage and contamination would be serious issues.
Instant On/Off and Smarter Controls
Older technologies like HID or fluorescent often come with long warm-up or cool-down times, which is why many facilities leave them on even when they don’t strictly need to. Turning them off means waiting for them to come back up to full brightness.
LED lights turn on and off instantly. There is no warm-up period, which completely changes how you can operate your lighting system:
- Occupancy sensors can shut off lights in unoccupied zones without worrying about slow restarts.
- Daylight sensors can dim or switch off fixtures when enough natural light is available.
- Schedules and advanced controls can ensure every area is lit exactly as much as it needs to be—no more, no less.
With LED, we no longer have to run lights wastefully just to avoid flicker or delay. We can implement more advanced lighting controls, not only to maximize energy savings but also to ensure the facility is running at optimal levels.
Where LEDs Deliver the Biggest Carbon Reductions
Commercial LED lighting first emerged as a new way to illuminate surfaces not far from the lights themselves. Today, the technology has evolved to the point where LEDs can be deployed at mounting heights that vastly expand their usage:
- Large warehouses and production floors
- Parking lots and parking garages
- Big-box retail and supermarkets
- Campus-style office buildings and hospitals
Those that have facilities with long operating hours stand to benefit the most from both lower costs and a reduced carbon footprint. If your lights are on:
- 12–24 hours a day
- Across large areas
- With high maintenance costs to reach and replace fixtures
…then upgrading to LEDs often pays for itself quickly in reduced energy and maintenance—and keeps paying you back for many years.
Interestingly, the potential for reducing your carbon footprint via LED lighting is still improving as production costs drop and performance improves.
If LEDs Are So Great, Why Hasn’t Everyone Switched?
The Carbon Trust, a global organization that assists businesses, the public sector, and governments to improve the pace at which they adopt sustainable energy practices, has looked closely at this question.
James Dunlop, Technology Manager at the organization, suggests that inertia surrounds some lighting systems that are “good enough,” even at the expense of excessive energy consumption. On occasion, some end users across the vast expanse of the business community lack the technical expertise to fully understand the potential benefits.
Once such an end user has started a partnership with a supplier that does possess the expertise, lighting solutions can be explained and subsequently deployed.
That’s precisely where Relumination fits in: we bring the technical knowledge, design experience, and implementation capabilities so you don’t have to become a lighting engineer just to modernize your facility.
Beyond Lighting: A Simple Framework for Shrinking Your Carbon Footprint
LED lighting is one of the best first steps, but it isn’t the only one. All commercial and industrial companies want to decrease their carbon footprint and reduce waste. While some view a reduction in waste as a difficulty, it’s actually quite simple to use less and shrink your consumption.
We’re not suggesting that you go “all in” and declare yourself carbon neutral, or that you reduce your CO₂ emissions by 100%, but there are several straightforward ways that you can help lessen waste and reduce your carbon footprint.
Here are three practical steps your business can use.
Step 1: Know Where You Stand
It’s difficult to reduce if you don’t know what you use.
- Find out what sort of emissions your buildings emit and start setting up a strategy.
- Measuring your carbon footprint will help you set up a plan to reduce it.
Once you outline a plan of attack, you can begin the next phase.
Step 2: Look for Solid Reduction Opportunities
A handy strategy is to identify low- to no-cost methods of reduction first. For example:
- Reduce heating and cooling bills by setting up a waste reduction strategy on temperature settings and usage.
- Place lights on a timer or install sensors so they aren’t on when they don’t need to be.
- Replace old lighting fixtures with energy-efficient LED bulbs and systems.
Lighting is often one of the fastest, cleanest wins here: a single LED retrofit project can permanently lower your base energy load.
Step 3: Upgrade Outdated Systems with Energy-Conscious Versions
Once you’ve tackled the “low hanging fruit,” you can move on to deeper upgrades:
- Place darkened screen films over windows to cut cooling costs in summer.
- Consider using solar panels and wind power to use less grid energy altogether.
- Upgrade your company vehicles to use renewable sources of fuel, which will reduce our dependency on fossil fuels.
Creative renewable technologies are emerging all the time. For example, Hawaii, which has always been a leader in green energy out of necessity, has set a bold goal to use 100 percent renewable energy by 2045, despite having limited land for large-scale projects.
One wind-based project Hawaii decided to fund uses a very unusual approach:
- Minnesota-based green energy firm SheerWind is working on an unusual wind turbine designed to catch relatively low-powered breezes and multiply their power using the Venturi effect.
- A 360-degree turbine with a cap sits on top of a funnel. As the turbine spins, the wind is pushed down into the funnel. As the funnel narrows, the pressure increases and the wind pushes harder. At the narrowest point—when the wind has reached maximum force—it pushes against turbines to create power, then diffuses out of the base.
Whether or not this specific technology becomes a standard, it illustrates an important point: there are many innovative ways to cut your carbon footprint, and lighting is one of the easiest places to start, with proven technologies and immediate payback.
