Are Car Air Fresheners Bad for the Environment?

There's a sense of pleasure and comfort when we step into a car that smells fresh and familiar. As many of us hang our favourite scents from rear-view mirrors or spritz our interiors, a pressing question emerges: how do these fragrant companions fare when it comes to their environmental footprint? 

Dive in as we explore the relationship between car air fresheners and the world around us. We also take a look at sustainable alternatives for conscious car enthusiasts. 

Environmental Concerns of Car Air Fresheners

Car air fresheners come in various forms, each offering a distinct method of fragrance delivery. A few of the most common types are:


  • Hanging cardboard fresheners
  • Vent clips
  • Gel fresheners
  • Diffusers
  • Oil wick fresheners
  • Sprays
  • Canned fresheners
  • Plug-in fresheners
  • Scented bags or sachets


However, each comes with a unique aroma and, unfortunately, its own set of environmental concerns. Some of the most notable issues include:

Chemical Components

One of the primary concerns surrounding car air fresheners is their chemical composition. Many conventional air fresheners contain harmful substances such as phthalates, formaldehyde, and volatile organic compounds (VOCs). 


When these compounds react with other elements in the air, they can produce pollutants harmful to both the environment and human health. Not only do they contribute to air pollution, but prolonged exposure to some VOCs has been linked to health issues, from minor headaches to more severe respiratory problems.


Another aspect to consider is the packaging of car air fresheners. Most air fresheners come in single-use plastic packaging, contributing to the growing plastic waste problem. With the UK striving to reduce its plastic waste, this is a significant point of contention. This non-biodegradable packaging not only clogs our already overflowing landfills but can also harm marine life when it finds its way to our oceans.

Waste and Disposal

Once the scent fades, the freshener's journey doesn't end. Many resist decomposition, especially those made from gel or encased in plastic. Improper disposal can lead these to sit in landfills for years or even centuries. Worse still, they may release toxins into the soil when they break down, threatening plant life and potentially entering water systems.

Sustainable Car Air Fresheners

Car air fresheners, like many products in today's eco-conscious market, are undergoing changes to become more environmentally friendly to battle against the negative effects they have on our planet. Here's how:

Natural and Sustainable Ingredients

Many brands are offering eco-friendly air fresheners made from natural ingredients like essential oils, plant extracts, and organic compounds that release fewer or no VOCs. This reduces potential health risks and limits environmental damage.

Furthermore, some air fresheners are now made using biodegradable materials such as wood, bamboo, or recycled paper. These materials break down more rapidly and harmlessly when disposed of.

Reusable and Refillable Designs

Rather than throwing away the whole freshener when it's spent, reusable and refillable options are now available, allowing users to replace scent cartridges or refill the fragrance. This reduces waste and can be more cost-effective in the long run. 

Longer-Lasting Products

Instead of producing items that last for only a short period, companies are creating products that maintain their scent for longer durations, meaning fewer replacements and less waste as a result.

Eco-Friendly Packaging

Many manufacturers now opt for sustainable materials like recycled paper or cardboard while also reducing the overall amount of packaging used. This minimises waste and reduces the carbon footprint associated with production and disposal.

Sustainable Production

Beyond the product itself, manufacturers are adopting practices that use less energy in the production process, aiming for a smaller carbon footprint. This might include everything from utilising renewable energy sources to streamlining manufacturing processes and reducing water consumption.
