How Does Tobacco Damage the Environment? Key Facts and Data
Key takeaways
The World Health Organization estimates tobacco's yearly footprint at 84 million tonnes of CO2, 600 million trees, 22 billion tonnes of water and 200,000 hectares of land, with about 4.5 trillion filters polluting the environment. In Canada, Environment and Climate Change Canada reports that cigarette butts topped the 2018 Shoreline Cleanup for abundance of litter.
Tobacco is usually discussed as a health problem. The same supply chain also uses farmland, water and fuel, and ends as litter that does not go away quickly. Two official sources give numbers: the World Health Organization for the global picture and Environment and Climate Change Canada for Canadian shorelines.
The global footprint
On World No Tobacco Day 2022 the WHO set out what it called the industry’s annual environmental cost:
| Resource | Estimated yearly amount |
|---|---|
| Carbon dioxide | 84 million tonnes |
| Trees | 600 million |
| Water | 22 billion tonnes |
| Land | 200,000 hectares |
| Cigarette filters entering the environment | About 4.5 trillion |
The WHO added that the industry’s carbon footprint is about one-fifth of that of the commercial airline industry. These are global estimates from the WHO, not Canadian measurements, and we found no country breakdown in the release.
Waste: the filter problem
The same WHO statement says tobacco products contain over 7,000 toxic chemicals that leach into the environment when discarded, and that cigarette filters contain microplastics. Its health promotion director is quoted as saying that “tobacco products are the most littered item on the planet.”
That squares with Canadian cleanup data. Environment and Climate Change Canada’s science assessment of plastic pollution reports that cigarette butts topped Canada’s 2018 Shoreline Cleanup for the highest abundance of litter, and that smoking-related litter made up 42.1% of the types of litter collected. The assessment lists cigarette butts among plastic items, but it does not say what share of a butt is plastic, so we do not quote one.
What Canada’s rules cover
Canadian tobacco law is written around health, not waste. The Tobacco and Vaping Products Act regulates how products are made, sold and promoted. We did not find a federal rule that makes manufacturers responsible for collecting or disposing of cigarette butts.
The government has taken one step that comes close in spirit. The Tobacco Charges Regulations make manufacturers pay for federal tobacco-related public health work; their stated purpose is cost recovery for those activities, and the sources we reviewed do not mention litter clean-up. Separately, some respondents to the second legislative review suggested messaging on “environmental impacts (such as litter, pollution and climate change)” as one way to discourage use. The review records that suggestion; it does not adopt it.
How to read the numbers
The WHO figures are global totals, so they are good for scale and not for judging any one country. The Canadian shoreline data counts what volunteers pick up from specific beaches in a given year, so it shows relative abundance, not the total volume of litter.
For the industry that generates this waste, see the tobacco industry hub, and for the rules that apply to packaging and sales, tobacco regulation.
Frequently asked questions
How much carbon does the tobacco industry produce?
WHO's 2022 statement puts the industry's annual footprint at 84 million tonnes of CO2 and says it is about one-fifth of the commercial airline industry's CO2 emissions.
Are cigarette butts really the most littered item?
WHO says tobacco products are the most littered item on the planet. In Canada, Environment and Climate Change Canada reports that cigarette butts topped the 2018 Shoreline Cleanup for highest abundance of litter.
Do Canadian rules address tobacco waste?
We did not find a Canadian federal regulation aimed at cigarette butt waste. In the legislative review, some respondents suggested health messaging about environmental impacts such as litter, pollution and climate change.
