If you believe that there is a risk of your suppliers causing air pollution, and you wish to include this topic in the annex to your Code of Conduct, you can add the following requirements to your Code of Conduct by clicking on "Save to clipboard".
Air pollution affects people's health and is detrimental to nature. How hazardous pollution is depends on the substances in the air, and the quantities involved.
- The supplier has the necessary permits for emission to air.
- The supplier complies with any other legal requirements on emissions to air (e.g. certain air pollution standards and limit values covering the specific type of production).
- The supplier documents and provides information on levels and types of relevant emissions to air - including documentation of adequate training of employees responsible for air emissions.
- The supplier includes diffuse emissions from its activities in estimates of total emissions.
- There are no visible signs of soot or other particles in and nearby the supplier’s facilities as a result of their emissions to air.
- The supplier keeps emissions in closed systems before emitted to air.
- The supplier cleans / treats emissions before emitted to air (e.g. by applying filters).
- The supplier clearly attempts to reduce air emissions through production efficiencies.
Air pollution can be due to a company's operations and activities, industrial processes, energy production and transport. Air pollution caused by flue gases typically concerns nitrogen oxides, sulphur dioxide, carbon monoxide, microparticles and dioxins. Air pollution from extraction systems is typically dust and volatile organic compounds (VOCs). It is also relevant to include other air emissions, such as ozone layer-depleting substances from refrigeration plant, or particles emitted by transport vehicles.
A distinction is made between:
- air-polluting substances (such as NOX, SOX, NH3, volatile hydrocarbons, dioxin and particles) and
- greenhouse gases (CO2, methane, nitrous oxide).
Air-polluting substances are directly toxic and hazardous when they are breathed in or discharged to nature, for example, while greenhouse gases contribute to global warming and other climate change. CO2 emissions create global climate change.
The supplier should monitor its emissions and take measures to reduce the number and quantity of air-polluting substances.
