What's the Environmental Impact of Chainsaw Waste?

Chainsaws are invaluable tools for cutting and trimming trees and wood. However, like most gasoline-powered equipment, chainsaws have an environmental impact that we should understand. In this post, I’ll overview the key environmental concerns related to chainsaw use and waste.

What's the Environmental Impact of Chainsaw Waste?

The environmental impact of chainsaw waste includes the production of pollutants such as carbon monoxide, hydrocarbons, and particulate matter, which can be harmful to the environment and contribute to smog formation and respiratory problems.

Exhaust emissions

The exhaust from chainsaw engines contains carbon monoxide, hydrocarbons, and nitric oxides, which make up about 10% of total chainsaw emissions. Studies have shown that emissions from two-stroke chainsaw engines are nearly ten times higher than emissions from other forestry machinery. This is concerning since these pollutants can contribute to climate change, air pollution, and health problems. There have been efforts to introduce exhaust emission testing for chainsaws similar to automobiles to help reduce pollution.

Fuel and oil consumption

Higher powered chainsaws require more fuel and oil per tree felled compared to lower powered saws. On average, about 1 liter of fuel is needed to cut one cubic meter of wood. The fuel consumption combined with the petroleum-based oils used to lubricate the chains result in more waste and emissions released into the environment.

Soil contamination

Oil leakage from chainsaws can contaminate forest soils. It’s estimated that around 6 million liters of oil penetrate the environment each year in Poland alone. Used motor oil runoff is especially problematic because of its strong toxic properties, which can harm plants and seep into water sources. Proper disposal and recycling is key to prevent soil contamination.

Lubricating oils

Petroleum-based lubricating oils are essential for chainsaw function but get sprayed into the environment during use. Studies suggest 100% of the lubricating oil applied to the chain affects the surrounding environment. The aerosolized oil contributes to air pollution and soil contamination.

Alternatives to reduce environmental impact

Alternatives to reduce the environmental impact of chainsaws include using electric or battery-powered chainsaws, which produce zero emissions and are quieter than gas-powered models

Biodegradable chainsaw chain oil

Biodegradable chainsaw chain oils made from renewable materials like canola oil are safer for users and the environment. Compared to traditional petroleum-based oils, biodegradable oils reduce soil contamination if spilled and cause less respiratory irritation with fewer dangerous fumes. However, they may be less effective for lubrication.

Health risks associated with chainsaw waste

Chainsaw operators may experience vibration and noise-related health issues, such as hand-arm vibration syndrome and hearing loss.

Exposure to exhaust emissions

The exhaust emitted from chainsaw engines contains high levels of pollutants that can be detrimental to human and animal health if exposure is prolonged. Breathing in these exhaust fumes on a regular basis may cause respiratory issues or exacerbate conditions like asthma. Proper protective equipment and limited exposure times can help reduce health risks.

Exposure to petroleum-based lubricants

The petroleum-derived oils used to lubricate chainsaw chains release harmful fumes and can irritate eyes, skin, and the respiratory tract. Long-term exposure without protection may lead to more severe respiratory problems for chainsaw operators and damage lung tissue. Using protective equipment and biodegradable alternatives can help mitigate exposure.

Regulations and guidelines

Here are the regulations for the same-

Emission standards

Unlike other small engine equipment, chainsaws currently don’t have regulated emission standards. However, there have been efforts to introduce on-road exhaust emission testing for chainsaws to help monitor and reduce pollution, similar to how automobiles are tested. Stricter regulation would encourage manufacturers to develop cleaner, more efficient chainsaw models.

Environmental impact of other gasoline-powered lawn and garden equipment

The environmental impact of gasoline-powered lawn and garden equipment includes the emission of pollutants such as carbon dioxide, carbon monoxide, hydrocarbons, volatile organic compounds, and nitrogen oxides.

Contribution to air pollutant emissions

In addition to chainsaws, landscaping equipment like leaf blowers, trimmers, and lawn mowers contribute substantially to air pollution from small gasoline engines. Gasoline-powered landscape maintenance equipment accounts for around 43% of volatile organic compounds (VOCs) and 50% of fine particulate matter (PM) emissions from mobile sources. The two-stroke engines common in this equipment are responsible for the bulk of fine PM emissions.


It’s clear that chainsaw waste can have detrimental impacts on the environment, from air and soil pollution to health hazards. As chainsaws remain an essential forestry and landscaping tool, adopting more sustainable practices is crucial. Using properly maintained equipment, following safety guidelines, and exploring electric or more efficient gas-powered alternatives can help reduce environmental harm. With more rigorous regulations and emission standards, chainsaw manufacturers will also be pushed to innovate cleaner solutions.

Frequently Asked Questions

How can I reduce the environmental impact of my chainsaw?

Regular maintenance, using the proper fuel and chain oils, operating your saw efficiently, and limiting unnecessary use can help reduce waste and emissions. Consider an electric or more fuel efficient model for your needs.

Are electric chainsaws more environmentally friendly than gasoline-powered chainsaws?

Electric chainsaws have zero direct emissions, less noise, and lower maintenance costs. However, their power may be limited compared to gas models. With green electricity sources, electric chainsaws are a more sustainable option.

What are the main pollutants emitted by chainsaws?

Carbon monoxide, hydrocarbons, nitrogen oxides, volatile organic compounds, and particulate matter make up the bulk of chainsaw engine exhaust emissions. These can contribute to climate change and health problems.

How does chainsaw waste affect soil quality?

Leaked motor oil, fuel, grease, and other fluids from chainsaws contaminate soils. Oil residue in particular can contain toxic compounds that harm microorganisms and plant life in the soil.

What are the health risks associated with chainsaw waste?

Prolonged exposure to chainsaw emissions can irritate eyes and airways or cause respiratory issues. Petroleum-based lubricants also pose contamination risks. Using protective equipment is important for mitigating health hazards.

Are there any regulations in place to control chainsaw emissions?

Unlike other small engines, chainsaw emissions are currently unregulated. Efforts have been made to introduce exhaust emission testing and standards similar to automobiles to reduce pollution.

How does chainsaw waste compare to other gasoline-powered lawn and garden equipment?

Chainsaws produce similar types of emissions as other landscape maintenance equipment, especially two-stroke engines. Together, these small engine machines account for a substantial portion of air pollutants from mobile sources.
