One pack of cigarettes (20 cigarettes)
Yksi savukeaski (20 savuketta)
Comprehensive LCA by Zafeiridou et al. (2018) in top journal. Carbon and water per cigarette well-established.
One pack of cigarettes produces 0.28 kg CO₂e and consumes 74 liters of water. But emissions are the smallest problem — tobacco kills 8 million people/year, and cigarette butts are the world's most littered item (4.5 trillion/year), each containing 15,000 microplastic fibers.
How was this number determined?
The Truecost score is calculated from absolute physical values. Each row below shows the measured value, how it was normalized, and where it comes from.
| Dimension | Absolute value | Score 100 = | Normalized | Weight | Weighted | Confidence |
|---|---|---|---|---|---|---|
| Carbon Emissions | 0.28 kg CO₂e | 9.5 kg CO₂e | 2.95 | ×0.35 | 1.03 | HIGH |
| Water Consumption | 74.0 liters | 3840 liters | 1.93 | ×0.2 | 0.39 | HIGH |
| Land Use | 0.4 m²·year | 51 m²·year | 0.78 | ×0.2 | 0.16 | MEDIUM |
| Waste | 0.035 kg | 5 kg | 0.7 | ×0.15 | 0.10 | HIGH |
| Toxicity | 50.0 µDALY | 162 µDALY | 30.86 | ×0.1 | 3.09 | MEDIUM |

- WHO FCTC (2022): Tobacco and its environmental impact
Curing (wood/coal burning) is the largest CO₂ source — more than all other stages combined (45 Mt CO₂e/year globally).
- Zafeiridou et al. (2018): ES&T — tobacco water footprint
Tobacco requires intensive irrigation. One pack's water = 1 person's drinking water for 37 days.
- Zafeiridou et al. (2018): ES&T — land use data
- WHO (2023): Tobacco and deforestation
Tobacco farming drives deforestation — 600 million trees cut annually for curing fuel (~1 tree per 15 packs).
- WHO (2022): Tobacco: poisoning our planet
- OceanCare (2023): Cigarette butts — toxic plastic pollution
4.5 trillion cigarette butts littered globally per year — #1 most littered item on Earth. Each contains 15,000 microplastic fibers.
- WHO (2023): Tobacco fact sheet — 8 million deaths/year
- Novotny et al. (2009): Cigarette butts and the case for environmental policy — International Journal of Environmental Research and Public Health
- CDC (2023): Tobacco lifecycle environmental impacts
Toxicity score vastly understates human health impact. Actual smoker DALY loss is orders of magnitude higher. Score here reflects environmental toxicity pathway only.
Comparisons
- 74 L water = one person's drinking water for 37 days
- A pack-a-day smoker (365 packs/year): 102 kg CO₂e + 27,000 L water
- 600 million trees are felled annually for tobacco curing
Methodology
Full supply chain LCA from Zafeiridou et al. (2018, ES&T) covering cultivation, curing, manufacturing, transport, and disposal. Water from irrigation data. Toxicity reflects environmental pathway only (not direct smoker health impact).
