What You'll Learn
NASCAR cars' non-EPA-regulated engines
NASCAR cars are equipped with non-EPA-regulated engines, which are exempt from the Clean Air Act. The Environmental Protection Agency (EPA) mandates certain levels of cleanliness from everyday passenger cars, but NASCAR vehicles are not subject to these same standards. This means that NASCAR cars can emit toxins without the use of mufflers, catalytic converters, or any other type of emissions control device. The EPA has, however, had the authority under federal law to ban engine or exhaust modifications that tamper with cars' emissions-control systems for about 25 years.
The non-EPA-regulated engines of NASCAR cars are a significant contributor to the sport's environmental impact. During a typical NASCAR race weekend, with over 40 cars racing at high speeds for 500 miles (804 kilometers), the fuel consumption is approximately 6,000 gallons (22,712 liters). This results in the emission of about 120,000 pounds (54,431 kilograms) of carbon dioxide for that race weekend. When multiplied by the roughly 35 races per year, NASCAR's annual carbon footprint reaches around 4 million pounds (1.8 million kilograms).
In addition to fuel consumption, NASCAR cars also go through a significant number of tires, with each team using approximately 8-10 sets of tires per weekend. The synthetic rubber used in tire production requires oil, and according to the Rubber Manufacturers Association, it takes about 7 gallons of oil to make one tire. This results in NASCAR using approximately 8,960 gallons of oil per race weekend for tires alone, further contributing to the sport's environmental impact.
While NASCAR's carbon footprint is substantial, some argue that it is relatively insignificant when compared to the annual US automobile-induced air pollution, contributing only about 0.00003%. Additionally, it is important to consider the advancements in automotive technology that have resulted from NASCAR racing. The research and development in the racing industry have contributed to safer and more efficient regular cars, potentially offsetting some of the environmental impact of the sport.
Despite these considerations, there are concerns about the environmental impact of NASCAR, particularly in light of the BP oil spill. Some suggest that regulations should be implemented to control the toxic emissions from NASCAR vehicles, encouraging the use of more economical and less polluting driving techniques.

The environmental impact of NASCAR tires
NASCAR races are notorious for their environmental impact, owing largely to their fuel consumption. However, the sport's tires also contribute to its carbon footprint.
NASCAR tires are radial and are filled with compressed nitrogen, which provides more control over tire pressure at high temperatures. Each team uses approximately 8-10 sets of tires per weekend, and it takes about 7 gallons of oil to make one tire. With 40 racers, that's 8,960 gallons of oil used on tires alone for a race weekend.
Estimates of the CO2 emissions resulting from burning this oil range from 149,090 pounds to 160,000 pounds per weekend. To put this in perspective, the average person contributes about 45,000 pounds of CO2 in an entire year.
NASCAR's tire sponsor, Goodyear, recycles old tires, and NASCAR has also begun planting ten trees for every green flag dropped to mitigate its environmental impact. However, the sport still faces criticism for its lack of regulation by the Environmental Protection Agency (EPA) and its contribution to air pollution.
While NASCAR's carbon footprint is significant, some argue that it is relatively minor compared to other sources of air pollution, such as the millions of registered automobiles in the US. Additionally, NASCAR's research has trickled down to regular cars, improving their safety and efficiency.
Overall, while NASCAR tires do contribute to the sport's environmental impact, the organization is taking steps to reduce its carbon footprint and promote sustainability.

NASCAR's switch to unleaded gas
NASCAR has long been criticized for its environmental impact. The sport, which involves powerful cars racing at extremely high speeds, is known for its high fuel consumption and carbon emissions. In a typical NASCAR race weekend, with over 40 cars racing at speeds close to 200 mph, the fuel consumption can reach about 6,000 gallons. This results in approximately 120,000 pounds of carbon dioxide emissions, contributing to NASCAR's significant carbon footprint.
Beyond fuel consumption, NASCAR cars also go through a large number of tires, which are made with synthetic rubber and require oil for production. The use of leaded gasoline, which was common in NASCAR well into the 2000s, further raised concerns due to its impact on nearby communities.
In response to these concerns, NASCAR began experimenting with unleaded fuel as early as 1998. However, the challenge lay in finding an alternative additive to lead, which lubricates engine valves. Despite this hurdle, NASCAR completed the transition to unleaded fuel in 2007, starting with the national series in 2006 and concluding with the premier class at the Fontana round in February 2007.
The switch to unleaded fuel had a notable impact on the communities living near racetracks. Researchers found that test scores in schools near the Daytona and Homestead tracks in Florida showed steady improvement after the transition to unleaded gasoline in 2007. This improvement was relative to students studying further away from the racetracks, indicating a potential link between the removal of leaded gasoline and enhanced educational performance.
While the switch to unleaded fuel is a positive step, there are still calls for NASCAR to further address its environmental impact. This includes exploring new ways to entertain fans while reducing energy intensity and developing less polluting technologies.

The use of ethanol in NASCAR races
NASCAR has been labelled as the most polluting sport in America, with its cars burning a lot of fuel and emitting about 120,000 pounds of carbon dioxide during a typical race weekend. The sport has also been criticised for being exempt from regulations by the Environmental Protection Agency, which has allowed NASCAR cars to emit toxins without using mufflers, catalytic converters, or any other emission control devices.
In 2010, NASCAR announced that it would start using a 15% ethanol-gas blend in its race cars, with the trade group Growth Energy signing a six-year deal to promote the product. This move was met with mixed reactions, with some questioning the fuel economy and performance of ethanol blends. However, the ethanol industry has touted the benefits of ethanol, claiming that it boosts horsepower and reduces emissions.
Since the debut of ethanol in the 2011 season, NASCAR has completed over 15 million competition miles using the Sunoco Green E15 fuel blend, which contains 15% ethanol. Race teams and engine builders have praised the fuel blend for boosting horsepower and reducing emissions.
The use of ethanol in NASCAR has been controversial, with critics arguing that it sets a bad precedent for the average driver and raises concerns about fuel economy and performance. However, supporters of ethanol claim that it is a great fuel that can demonstrate its benefits through its use in NASCAR.
While the environmental impact of NASCAR is significant, it is important to consider the impact of other factors such as fan travel, air travel, TV crews, and the land used for racetracks. Additionally, NASCAR has taken steps towards sustainability by using ethanol-blended fuel, which has the potential to reduce emissions and improve fuel efficiency.

The impact of NASCAR on local air quality
NASCAR races have been labelled as "wasteful" and bad for the environment. The cars' non-EPA-regulated engines and high speeds make the sport one of the least environmentally friendly. NASCAR cars have a standard fuel efficiency of 5 miles per gallon, while many commuter cars get up to 50 miles per gallon. The emissions from NASCAR races quickly add up, and the gasoline burned also contains particulate matter, sulfur oxides, and other pollutants that destroy air quality.
A typical NASCAR race weekend with over 40 cars racing at high speeds for 500 miles burns about 6,000 gallons of fuel. Each gallon burned emits about 20 pounds of carbon dioxide, so that's about 120,000 pounds of CO2 emitted for a race weekend. Multiply that by roughly 35 races per year, and NASCAR's annual carbon footprint is around 4 million pounds. The energy expended in one race could power more than three houses or drive seven cars for a year.
NASCAR cars also use a lot of tires, with each team using about 8-10 sets of tires per weekend. The tires are made with synthetic rubber and require oil to produce. NASCAR uses about 8,960 gallons of oil per race weekend on tires alone, which emits roughly 149,090 pounds of CO2.
In addition to the emissions from the cars, NASCAR races also impact local air quality through noise pollution. Engine noise levels can reach as high as 140 decibels, which can cause severe damage to a person's sense of hearing. The noise levels last for about three to four hours, the average duration of a NASCAR race.
NASCAR has faced criticism and is working to reduce its carbon footprint. In 2011, NASCAR started using ethanol, which has reduced emissions by 20%. They have also installed solar panels at several tracks and planted thousands of trees. While NASCAR is taking steps to improve its environmental impact, it is clear that the sport has a significant effect on local air quality through fuel consumption, emissions, and noise pollution.
