Smoking's Environmental Impact: A Polluting Habit

Smoking is known to have a detrimental impact on human health, but it also has a significant and often overlooked effect on the environment. The tobacco industry has been called out by the World Health Organization (WHO) for its environmental consequences, including the loss of millions of trees, land, water, and the release of millions of tonnes of CO2. The production, processing, and transportation of tobacco contribute to global warming, and the cigarette butts that are discarded are the most commonly littered item worldwide, polluting our oceans, rivers, soil, and beaches. With cigarettes containing over 7000 toxic chemicals, the environmental impact of smoking is an urgent issue that requires attention and action.

Cigarette butts are the most littered item

The tobacco industry has historically marketed filtered cigarettes as healthier, despite research suggesting otherwise. The filters are made of cellulose acetate, which only degrades under severe biological circumstances, such as when filters collect in sewage. Even under optimal conditions, it can take at least nine months for a cigarette butt to decompose. This has led to cigarette butts becoming a significant source of pollution, with studies finding them to comprise 25-50% of all collected litter items from roads and streets, and 30-40% of all items collected in annual international coastal and urban cleanups.

The cost of cleaning up littered tobacco products falls on taxpayers, rather than the industry creating the problem. However, some countries and cities, such as France, Spain, and San Francisco, have implemented "extended producer responsibility legislation," which makes the tobacco industry responsible for clearing up the pollution it creates. This type of policy has been encouraged to be implemented globally, along with other suggestions such as banning cigarette filters, implementing deposit-return schemes, and creating special taxes on tobacco products to fund cleanup efforts.

The environmental impact of cigarettes begins even before they are lit, with the growing of tobacco plants contributing to water and farmland depletion, deforestation, and carbon emissions. The World Health Organization (WHO) has raised alarms about the tobacco industry's environmental impact, calling for steps to make the industry more accountable for the destruction it is causing. WHO's report "Tobacco: Poisoning our Planet" highlights that the industry's carbon footprint from production, processing, and transporting tobacco is equivalent to one-fifth of the CO2 produced by the commercial airline industry each year, contributing to global warming.

The tobacco industry's carbon footprint

The tobacco industry has a significant carbon footprint, impacting the environment at every stage of a cigarette's life cycle. From the growing of tobacco plants to the disposal of cigarette butts, the industry contributes to climate change, water and soil depletion, and deforestation.

Tobacco is a highly engineered product, requiring substantial resources for its production. The global cultivation of tobacco demands extensive land and water use, as well as the application of pesticides and labour. According to the World Health Organization (WHO), the tobacco industry costs the world 600 million trees, 200,000 hectares of land, and 22 billion tonnes of water annually. This is particularly detrimental as tobacco cultivation is concentrated in low- and middle-income countries, where these resources are desperately needed for food production.

The carbon footprint of the tobacco industry extends beyond resource depletion. The energy and fuel consumption associated with tobacco cultivation, processing, and transportation contribute to climate change. The industry's carbon dioxide emissions are equivalent to one-fifth of the CO2 produced by the commercial airline industry each year, further exacerbating global warming.

Cigarette butts, which contain toxic chemicals, are also a significant source of pollution. They are the most commonly littered item, with an estimated 4.5 trillion cigarette filters polluting oceans, rivers, soil, and beaches annually. These filters are made of cellulose acetate, a type of plastic that can take up to two years to biodegrade. When improperly disposed of, cigarette butts release harmful chemicals such as cadmium, lead, formaldehyde, and arsenic into the environment.

The environmental impact of the tobacco industry is not limited to ecological damage. The costs of cleaning up tobacco product waste fall on taxpayers and governments, with some estimates suggesting spending of tens of billions of dollars annually. Additionally, tobacco-related fires contribute significantly to environmental damage, with global spending on smoke-related fires reaching $27 billion in 1998.

Addressing the tobacco industry's carbon footprint requires a multi-faceted approach. Implementing extended producer responsibility legislation, as seen in France, Spain, and San Francisco, holds the industry accountable for clearing up the pollution it creates. Supporting tobacco farmers in transitioning to sustainable crops and imposing strong tobacco taxes, including environmental taxes, can also help reduce the industry's carbon footprint. Additionally, raising awareness about the environmental impact of cigarette butts and providing accessible waste collection methods can promote responsible disposal practices.

Cigarette butts damage aquatic life

Cigarette butts are the most common form of litter, with an estimated 4.5 trillion cigarette butts thrown away every year. They contain all the carcinogenic chemicals, pesticides, and nicotine that make tobacco use the leading cause of preventable death worldwide. When these butts end up in aquatic environments, they can have serious effects on the creatures within.

Cigarette filters are made of tiny pieces of plastic called cellulose acetate, which does degrade in the presence of UV light but is not truly biodegradable. The sun's light causes them to break into smaller pieces, but those pieces persist in the environment. Cigarette butts contain several harmful chemicals that can be leached into the environment, particularly in marine settings.

The chemicals in cigarette butts can kill both marine and freshwater fish. A study from San Diego State University suggests that one smoked cigarette butt in a single litre of water is enough to kill both types of fish. Another study found that leachate from smoked cigarette filters (without tobacco) was less toxic, with LC50 values of 1.8 and 4.3 cigarette butts per litre for marine topsmelt and freshwater fathead minnow, respectively. Unsmoked cigarette filters (without tobacco) were also toxic, with LC50 values of 5.1 and 13.5 cigarette butts per litre for both fish species.

The plastic packaging around a pack of cigarettes can also harm aquatic life. It can be mistaken for a jellyfish or other food item and eaten, leading to suffocation or digestion problems. This can occur in numerous ocean species and could easily be fatal.

To protect aquatic life, it is crucial to reduce cigarette butt litter and lower the smoking rate. Prohibitions on smoking in outdoor public places, including parks and beaches, can help prevent butt waste from reaching aquatic environments. Additionally, more disposal locations for smokers and the encouragement of pocket ashtrays can minimise the impact of cigarette litter on marine life.

Cigarette filters are plastic pollutants

Smoking has a significant impact on the environment, from the growing of tobacco plants to the disposal of cigarette butts and packaging. One of the most concerning aspects is the presence of plastic in cigarette filters, which has led to widespread plastic pollution.

Cigarette butts are the most littered item globally, with over 4.5 trillion filters polluting oceans, rivers, sidewalks, parks, soil, and beaches annually. This is because the majority of smokers incorrectly assume that filters are made from biodegradable materials like cotton. In reality, most modern cigarette filters are made from cellulose acetate, a type of plastic that can take up to 12 years to fully decompose. During this slow degradation process, the average cigarette filter releases 12,000 microfibers, which contribute to the growing issue of microplastics in our waterways and oceans. These microfibers are consumed by plankton, which form the base of the marine food chain, leading to toxic chemicals being ingested by marine life and potentially entering the human food supply.

The widespread littering of cigarette butts has severe environmental consequences. When cigarette butts are discarded on the ground or in sewers, they are often washed into storm drains and end up in waterways. This leads to the leaching of toxic chemicals into aquatic environments, killing fish and other aquatic organisms. In addition, the tobacco industry has largely evaded responsibility for the cleanup of cigarette waste, with the financial burden falling on taxpayers and communities instead.

Efforts are being made to address this issue. The World Health Organization (WHO) has raised alarms about the environmental impact of the tobacco industry, calling for the industry to be held accountable for the destruction it causes. Some countries and cities, such as France, Spain, and San Francisco, have implemented "extended producer responsibility legislation," making the tobacco industry responsible for cleaning up the pollution it creates. The European Union is also taking steps to reduce single-use plastics, including requiring the tobacco industry to fund the cleanup of cigarette stubs. Additionally, organizations like Wild at Heart Legal Defense Association Taiwan are advocating for public awareness, proper disposal of cigarette butts, and the phasing out of plastic filters by international tobacco companies.

Despite these initiatives, the problem of plastic cigarette filters persists. The tobacco industry continues to market filters as providing health benefits, despite a lack of evidence to support these claims. While some have proposed biodegradable filters as a solution, experts warn that these filters still contain toxins that can take a long time to degrade, and may even encourage more littering. Ultimately, the most effective way to reduce the environmental impact of smoking is to address the root cause: the global consumption of cigarettes.

Smoking contributes to deforestation

Smoking has a significant environmental impact, from the growing of tobacco plants to the disposal of cigarette butts. One of the most concerning effects is its contribution to deforestation.

Tobacco cultivation is a major driver of deforestation, especially in the Global South. The process of curing tobacco leaves, specifically the Virginia variety, is a significant contributor. This variety is commonly used in American Blend cigarettes and requires hot air curing. The leaves are hung in a barn with heated air, often generated by burning wood, leading to extensive wood fuel usage. This practice has been linked to deforestation in countries like Tanzania, where forests are cleared to create new fertile fields for tobacco cultivation.

The demand for tobacco has led to the clearing of forests in low- and middle-income countries, where tobacco growing is concentrated. The percentage of deforestation caused by tobacco farming reached 4% globally by the early 2000s, with much higher rates in specific countries: China (18%), Zimbabwe (20%), Malawi (26%), and Bangladesh (>30%). The expansion of tobacco farming has resulted in large-scale forest removal, soil degradation, and increased usage of pesticides and chemicals, further exacerbating environmental issues.

Additionally, cigarette butts, which contain toxic chemicals, are often littered and can cause forest fires, contributing to deforestation. They are the most commonly collected waste item during beach clean-ups and make up an estimated 25-50% of all collected litter items from roads and streets. The toxic chemicals in cigarette butts can leach into the environment, impacting aquatic ecosystems and killing aquatic organisms.

The environmental impact of smoking extends beyond deforestation, including water depletion, fossil fuel depletion, and carbon emissions. The tobacco industry's carbon footprint contributes significantly to global warming, with production, processing, and transportation equivalent to one-fifth of the CO2 produced by the commercial airline industry annually.

Addressing the environmental impact of smoking requires a multi-faceted approach. Implementing extended producer responsibility legislation, as seen in France, Spain, and San Francisco, holds the tobacco industry accountable for clearing up the pollution it creates. Supporting tobacco farmers in transitioning to sustainable crops, imposing strong tobacco taxes, and offering services to help people quit tobacco are also crucial steps.
