The ten pollutants with the largest volumes of inputs to the environment (air, soil, water, wastewater) make up our "Top 10 Pollutants". The figure for 2010 clearly shows that a 'major polluter' can be identified for most of these pollutants. 'Major polluter' refers to a sector of industry whose share of the pollution reported in Thru.de is particularly high.
The major polluter by far for carbon dioxide emissions (CO2) is the energy industry. The second highest-ranking chlorides are caused in almost equal part by the chemical industry and the minerals processing industry, followed by waste and wastewater management (municipal wastewater treatment plants in particular). It should be noted that total chloride volumes owe to discharges into water, inputs to soil as well as to releases in wastewater.
The major polluter for carbon monoxide emissions (CO) is the metalworking industry. The minerals processing industry – and coal mining in particular – is the major polluter for methane emissions, closely followed by waste and wastewater management and landfills in particular. Nitrogen oxide and sulphur oxide emissions, similarly to CO2, originate mainly in the energy industry, although their lead over the next closest sectors is much narrower.
The main sources of total organic carbon (TOC) are the chemical industry, the food industry, and the paper and wood industry. However, waste and wastewater management, especially wastewater treatment plants, were also responsible for a large share of TOC volumes. Emissions to water and discharges in wastewater are grouped together in this graph. Wastewater treatment facilities are also the major polluters for total nitrogen.
The sector "Other industries" had the largest share of non-methane volatile organic compounds (NMVOC) emissions. This sector includes facilities where surfaces are coated with solvents, such as automobile manufacturers and paint shops in particular. Intensive livestock production is the clear leader in ammonia emissions (NH3). The chemical and minerals processing industries represent smaller shares.
