Frequently asked questions
NOx refers to a group of highly reactive gases containing nitrogen oxides, including nitric oxide (NO) and nitrogen dioxide (NO₂). These gases are produced during combustion processes when any type of fuel is burned, such as natural gas, oil, kerosene, wood or coal. This includes cooking with gas or oil stoves and ovens, burning firewood in wood burning stoves and log burners, vehicle exhaust fumes, wildfires or the burning of charcoal or tobacco. These activities can introduce a range of pollutants into the air.
In the context of emissions, NOx refers to nitrogen oxides released as a result of various combustion or burning processes. These emissions are a major contributor to air pollution, particularly in urban areas. Although you may feel like you can shut this pollution out of your home, modern houses are increasingly well sealed and energy efficient, which means you might be shutting pollution inside with you.
Sources of NOx include:
• Gas stoves and ovens
• Oil or propane stoves and ovens
• Wood burning stoves and log burners
• Vehicle emissions, e.g. cars, trucks, buses
• Burning charcoal, e.g. barbeques
• Tobacco smoke
• Wildfires, lightning, volcanic activity
High levels of NOx can cause respiratory issues, especially for individuals with conditions like asthma. Long-term exposure can lead to decreased lung function and other respiratory diseases.
NOx reduction is a key focus in environmental regulations aimed at improving air quality and reducing health risks.
NOx contributes to the formation of ground-level ozone (smog) and particulate matter, which can harm human health. It can also play a role in the formation of acid rain, which can damage ecosystems, soils and bodies of water.
