With the days getting longer, many homeowners’ thoughts turn to the work that waits in their yards. Many people associate air pollution with cars, airplanes, energy-producing facilities, and other large fuel consumers. The small engines used in lawn mowers, hedge trimmers, chain saws, and leaf blowers, however, represent a significant source of air pollutants. Indeed, most small engines emit high levels of carbon monoxide (CO), a colorless, odorless, poisonous gas. In addition to CO, small engines emit ozone-forming hydrocarbons and nitrogen oxides. Ground-level ozone impairs lung function and contributes to smog formation. According to the Government of Canada, a gasoline-powered lawn mower emits about 48 kilograms of greenhouse gases in one season. There are ways to help clean the air while maintaining your yard. Here are a few ideas to get you started. Avoid Spills and Overfilling · Spilling gas and overfilling the tank allow for gas to evaporate · With evaporation, hydrocarbons are released into the atmosphere Maintain Equipment · Change oil and clean or replace air filters regularly · Use the proper fuel/oil mixture in two-stroke equipment · Keep blades sharp to improve fuel efficiency Use Manual Tools · No fuel required, which means no emissions produced · An easy way to get exercise and have fun, without any pollution Reduce Mowing Time · The less time the mower is running, the less fuel is used · Decrease lawn area with trees or shrubs or use low-maintenance turf grasses that grow slowly Recycle old equipment · Instead of sending old equipment to the landfill, send it to a recycling center · Many lawn tools can be converted into raw materials for use in other products. · Turn in your old high-polluting lawn mower at the nearest Home Depot between April 17-27, 2008 in return for an instant rebate of up to $100 on an energy-efficient, low-emission alternative. · Mowers with newer engines are subject to stricter emissions standards, so they will likely burn cleaner than your old lawn mower.
