Reduce methane emissions
Reducing methane emissions is crucial in the fight against climate change. Methane is a potent greenhouse gas with a warming effect 86 times stronger than carbon dioxide over a 20-year period. The good news is that there are several strategies we can employ to reduce methane emissions and mitigate their impact on the environment.
One of the most significant sources of methane emissions is the oil and gas industry. Oil and gas operations have been identified as the largest source of methane emissions from the fossil fuels sector. However, there is strong potential to reduce these emissions at a low cost. Quick and decisive action in this sector could have a significant impact, potentially avoiding up to 0.1 degrees Celsius of warming by the middle of the century. This would be equivalent to eliminating the emissions of every car and truck on the planet. To achieve this, we can focus on flaring and venting reduction, as well as tackling fugitive methane emissions. While technology for detecting and measuring methane emissions has improved, effective leak detection and repair often require multiple complementary approaches, including satellites, aerial surveillance, and on-ground survey teams.
Another major source of methane emissions is agriculture, which accounts for about 40% of human-caused methane emissions. Livestock rearing, animal manure management, and rice production are significant contributors within this sector. To reduce methane emissions from livestock manure management, it is recommended to switch to practices that manage manure in drier, aerobic conditions. This is because liquid manure management systems lead to anaerobic conditions that increase methane production. Additionally, when selecting a manure management practice, it is essential to consider its impact on other greenhouse gas emissions, such as nitrous oxide, and on carbon sequestration.
Individuals can also play a role in reducing methane emissions from smaller sources in their daily lives. For example, vehicles, construction equipment, lawn mowers, and other gas-powered tools are significant contributors to methane and other greenhouse gas emissions. By choosing fuel-efficient vehicles, carpooling, biking, using public transportation, or opting for electric alternatives, individuals can significantly reduce their carbon footprint. Additionally, simple actions such as keeping tires properly inflated, turning off engines when idling, and reducing energy consumption at home can collectively make a substantial impact on methane emissions.
Finally, governments and industries have a crucial role in driving systemic change to reduce methane emissions. The Global Methane Pledge (GMP), launched in 2021 by the United States, the European Union, and other CCAC partners, aims to reduce global methane emissions by at least 30% from 2020 levels by 2030. This could have a significant impact on warming, eliminating over 0.2 degrees Celsius of warming by 2050. Governments can support and incentivize industries to adopt cleaner production techniques, improve waste management, and reduce methane emissions.

Clean up hazardous waste sites
Hazardous waste sites are a significant source of pollution and can have detrimental effects on the environment and human health. The US Environmental Protection Agency (EPA) has developed several programs to address the cleanup of these sites, with a focus on flexibility and results.
One such program is the Superfund program, established in 1980, which aims to locate, investigate, and clean up large, abandoned hazardous waste sites. The Superfund program oversees long-term ("remedial") cleanups at National Priorities List (NPL) sites and short-term ("removal actions") cleanups, as well as responses to chemical and oil spill emergencies. The EPA compiles a database of potential hazardous substance release sites and evaluates the potential for a release using the Superfund cleanup process steps.
Another program is the Brownfields and Land Revitalization cleanup enforcement program, which provides guidance and uses site-specific enforcement tools to assist parties seeking to clean up, reuse, or redevelop contaminated properties. This program addresses available liability protections and can help transform contaminated land into community assets.
The EPA also provides guidance and information to help the regulated community and program implementers learn about and enforce the hazardous waste cleanup process. The first step in most cleanup programs is an initial site assessment, where state or EPA technicians require facilities to produce information on site conditions, releases, potential releases, and exposure pathways. This step helps determine whether a cleanup is needed and identifies areas of concern. Following the initial assessment, site characterization is necessary to ascertain the nature and extent of contamination before selecting a final remedy.
During the cleanup process, interim actions may be required to control or abate ongoing risks to human health and the environment. These actions can include providing alternative drinking water sources if contamination of water supplies is suspected. The EPA has developed guides to assist in the selection of appropriate corrective measures and to help parties working on hazardous waste cleanup.
Overall, the EPA's programs and resources aim to provide a flexible and effective approach to cleaning up hazardous waste sites, protecting human health, and mitigating the environmental impact of pollution.

Improve indoor air quality
Improving indoor air quality is of critical importance to health, especially as Americans spend 90% of their time indoors. Poor indoor air quality can cause a range of health issues, from headaches to lung cancer.
There are three basic strategies to improve indoor air quality: eliminate individual sources of pollution, reduce their emissions, and increase ventilation.
Eliminating Individual Sources of Pollution
The first step is to identify sources of pollution in the home. Common indoor allergens include pet dander, mould and mildew, and dust. Other sources of pollution include asbestos, gas stoves, and tobacco smoke. Once identified, these sources can be sealed off or enclosed, or adjusted to decrease emissions. For example, gas stoves can be adjusted to decrease emissions, and asbestos can be sealed off.
Reducing Emissions
Appliances such as cook stoves release emissions directly into the home. Furnaces and water heaters, on the other hand, vent most combustion by-products outside. When purchasing new appliances, opt for energy-efficient models with fewer emissions.
Increasing Ventilation
Ventilation helps to remove or dilute indoor airborne pollutants. Natural ventilation, such as opening windows and doors, can improve indoor air quality by reducing pollutants and moderating indoor temperature. However, if you live near a source of outdoor air pollution, such as a freeway or factory, opening windows and doors may not be advisable. In these cases, mechanical means of increasing ventilation, such as energy-efficient heat recovery ventilators, can be used.
Other Tips
- Plant trees: Trees filter pollutants, absorb carbon dioxide, and release oxygen into the atmosphere.
- Choose fuel-efficient vehicles: Vehicle exhaust is a major source of air pollution. Opt for fuel-efficient cars and consider carpooling, biking, or taking public transportation.
- Save energy: Turn off electrical appliances when not in use, and choose efficient appliances and heating systems.
- Avoid burning garbage: Burning household waste is dangerous to health and the environment and is generally against the law.

Reduce vehicle emissions
Vehicle emissions are a significant contributor to air pollution, which has detrimental effects on the health of humans, animals, and plants. To reduce vehicle emissions, individuals can make changes to their driving habits and vehicle maintenance routines, while governments can implement policies and incentives to encourage the use of cleaner vehicles and fuels.
One way to reduce vehicle emissions is to drive less and opt for more sustainable modes of transportation, such as walking, biking, carpooling, or taking public transit. This not only reduces emissions but also improves fuel efficiency and saves money. When driving is necessary, individuals can adopt fuel-efficient driving habits, such as avoiding aggressive acceleration and hard braking, removing unnecessary accessories like roof racks, and maintaining proper tire pressure. Proper vehicle maintenance is also key, including regular tune-ups, oil changes, and the use of recommended motor oils and fuel additives to improve engine efficiency and reduce emissions.
When purchasing a new vehicle, individuals can choose fuel-efficient models with low greenhouse gas emissions. Electric vehicles, hybrids, and compact fuel-efficient cars are cleaner alternatives to traditional gasoline-powered cars. Governments can support this transition by offering incentives, such as subsidies or tax breaks, for the purchase of cleaner vehicles. Additionally, governments can implement stricter emission standards and regulations to ensure vehicles meet environmental performance criteria, as well as promote the development and adoption of innovative emission reduction technologies.
Another way to reduce emissions is to limit idling. Modern vehicles do not require prolonged idling to "warm up" in cold weather, and idling creates a hotspot of pollution, wasting fuel and causing unnecessary engine wear. Implementing no-idling policies, especially for school buses, can significantly reduce children's exposure to diesel exhaust and improve air quality.
By combining individual actions with governmental support and policies, we can effectively reduce vehicle emissions, improve air quality, and combat climate change.
