How Much Carbon Dioxide Does A Candle Produce?

Candles are a wonderful source of light and warmth, but they can also affect the air quality in your home. After a stressful day at work or during a relaxing bubble bath or to cover up the smells of a burnt dinner disaster, candles are great for providing ambiance and a fresh aroma. However, are they affecting the air pollution in your home?

Burning a paraffin candle releases about 10 grams of carbon per hour. Most candles are made out of paraffin, which is a heavy hydrocarbon derived from crude oil. When a paraffin candle burns, the hydrogen combines with the oxygen in the atmosphere to become carbon dioxide and steam. Most of the matter ends up as these two gases.

Can A Candle Cause Carbon Monoxide Poisoning?

A candle can indeed produce levels of carbon monoxide that are measurable from incomplete combustion. However, it's extremely unlikely that you'll ever experience anything harmful from using candles.

Carbon monoxide is typically associated only with exhaust, like a car. However, there are many sources where carbon monoxide can exist. These include grills, wisps of smoke, portable generators, and any kind of fire, gas, or charcoal stove.

Any item within your house which requires power will produce carbon monoxide around it. This means you need to be extra careful around these items.

You shouldn't leave a candle burning in a room which is completely closed off. Instead, place the candle somewhere else in the room.

However, if you do decide to light a candle, please remember to keep it away from children and pets. Also, make sure that you extinguish the flame after every use.

How Do Candles Burn?

Candle burning produces a lot of CO2. A typical candle burns for approximately 20 minutes, during which time it creates enough heat to melt about 1/4 cup of wax. As the wax melts, it turns into a hot gas that is pulled up through the wick by capillarity. Once the wax reaches the tip of the wick, it combusts and releases its stored chemical energy as heat, light, water vapor, and carbon dioxide.

A typical candle burns for approximately twenty minutes, during which time the candle creates enough heat to melt approximately 1/4 cup of melted wax. As the wax heats up, it becomes a hot gas that is drawn up through the wick. At the end of the burn, the wax combusts releasing its stored chemical energy as light, heat, water vapor, and CO2.

As the wax combusts, it generates enough heat to radiate back and start melting more wax. This continues until the fuel is exhausted or the heat is removed.

Because candles are made out of wax, they release a lot of CO2 into the atmosphere. One lit candle uses about 10 grams of wax, which translates to roughly 0.5 pounds of CO2.

Why Does The Flame Of A Candle Always Point Up?

The behavior of candle flames always points upwards because the hot air inside the flame rises faster than the cool air outside the flame. This causes the warmer air to move up and outwards, creating a continuous flow of air around the flame. Because there is no place for the hotter air to escape, it stays near the surface of the flame where it continues to heat the surrounding air.

This process happens continuously until the temperature difference between the air inside and outside the flame becomes small enough that the air outside the flame begins to cool down and fall back towards the flame. At this point, the air inside the flame stops rising and the flame goes out.

Because the air inside the flame doesn't stop moving, it keeps heating the surrounding air and causing the air above the flame to continue rising. This continues until the air outside the flame reaches the same temperature as the air inside the flame. Once this occurs, the air inside the fire stops rising and the flame dies out.

Are Candles Bad For Your Home's Air Quality?

Candles are bad for your home's air quality. Not only do they emit toxic fumes into the air, but they also leave behind sooty residue on surfaces throughout your house. You may think that you can clean up after yourself, but if you burn candles regularly, you'll find that cleaning up the mess becomes increasingly difficult.

Make sure that you buy candles that are labeled as safe for indoor use. Look for those that say they are non-toxic, biodegradable, and environmentally friendly. Avoid buying candles that are made out of beeswax, soybean oil, palm oil, coconut oil, or tallow. These oils are highly flammable and can easily catch fire.

Don't forget to dispose of your old candles properly. Don't just throw them away in the trash. Instead, recycle them at your local recycling center. Recycling centers accept used candles, which means that you don't have to worry about disposing of them improperly.

Are Candles Harmful To The Environment?

There are several types of candle wax available today. Some are made from petroleum products, others from natural sources like palm oil and coconut oil. Each type of wax has its pros and cons.

Paraffin wax is the most common type of wax used in candles today. It comes from fossil fuels and releases harmful chemicals into the atmosphere when burned. Paraffin wax is also known to cause respiratory issues and skin irritation.

Soy wax is another type of wax that is commonly found in candles. It is derived from soybeans and is considered a renewable resource. However, it still produces carbon dioxide during combustion.

Coconut oil is another type of wax used in making candles. It is extracted from coconuts and is considered a sustainable alternative to traditional paraffin wax. Coconut oil burns cleanly without releasing any harmful pollutants into the air.

Beeswax is another type of wax commonly used in candles. It is produced naturally from honeybees and is considered a renewable source. Beeswax is also non-toxic and biodegradable.

Palm oil is another type of natural wax that is commonly used in candles. Palm oil is derived from palm trees and is considered a renewable energy source. Palm oil is also non-toxically and biodegradable, however, it emits high levels of greenhouse gases during combustion.

Natural waxes include candelilla wax, carnauba wax, rice bran wax, jojoba wax, and lanolin. These waxes are derived from plants and are considered safe alternatives to paraffin wax.

Are Soy Candles Harmful To The Environment?

Soy candles are healthier for the environment than traditional paraffin candles. Not only are they made from renewable resources, but they also last longer and produce less soot. Because they are made from soy wax instead of petroleum, they are also free of carbon soot.

However, soy candles still produce a small amount of soot because they burn at a pure blue flame. So if you prefer a cleaner scent, you may want to consider using a soy candle.

You'll find that soy candles are a great choice for those who want to reduce their environmental impact. You won't regret making the switch to soy candles!

Are Scented Candles Harmful To The Environment?

Aromatic candles are great for adding a little extra oomph to any room. But if you've ever used one, you'll know that it can leave behind a lingering scent that lingers long after the candle burns out.

Paraffin wax is the main ingredient in most scented candles. Paraffin wax comes from fossil fuels, such as coal, petroleum, and natural gas. These fossil fuels release toxins into the atmosphere during combustion, including carbon monoxide, formaldehyde, benzene, and xylene.

A study from South Carolina State University found that paraffin candles give off harmful fumes that cause lung cancer and asthma. So, if you're worried about the impact of burning scented candles, consider switching to soy wax candles instead. Soy wax doesn't emit any toxins into the air, and it won't leave behind a lingering scent.

Do Candles Contribute To Global Warming?

To some extent, yes, candles contribute to global warming. You should only buy candles that are labeled 100% natural. Many candles are made with synthetic materials and may emit toxins. Some brands of candles are made with recycled plastic bottles. These candles are usually cheaper, but they are still not safe.

If you must light candles, try buying organic cotton wicks instead of traditional ones. Cotton wicks do not contain any toxins and are safer than traditional wicks. You can even purchase reusable cotton wick holders.

How Can I Use Candles To Their Full Potential While Minimizing The Negative Effects?

Candles are great for creating ambiance, adding warmth and beauty to any room. However, if you want to maximize the benefits of candles without contributing to global warming, you should consider making your own. You can easily make your soy candles at home, and they'll last longer than store-bought or candle brand ones.

Soy candles are made from soybean oil, which is derived from soybeans grown by farmers all over the world. Soy candles are biodegradable and non-toxic, and they burn at cooler temperatures, which results in a cleaner and longer burning candle.

You can also make your beeswax candles, which are made from honeybees' wax comb. Beeswax candles are naturally antibacterial and antifungal, and they smell amazing. They also burn at lower temperatures, which makes them safer for children and pets.

Finally, you can make your coconut wax candles, which are made with coconut oil. Coconut wax candles are naturally antimicrobial and antifungal. They also burn at cool temperatures, which helps prevent fires.

All of these options are great alternatives to traditional candles, and they won't harm the environment. So, next time you light up a scented candle, think about making your own instead!

Smell is one of the human senses which can flow through the whole body. I am the Founder of where we talk all about scented candles. Known as Candace the Candle Girl, I know pretty much all there is to know about scented candles. I make and sell them on Etsy and Ebay - so be sure to ask if you have any burning questions :) (pun intended ;) )
