Emissions to air

Regular monitoring of our emissions to air is a part of environmental management at BASF. In addition to greenhouse gases, we also measure emissions of other air pollutants. These include inorganic compounds such as carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxide, ammonia and other inorganic compounds, dust, heavy metals and non-methane volatile organic compounds (NMVOCs).

¹ See table below for the composition of the air pollutants

Our reporting does not take into consideration air pollutant emissions from oil and gas operations due to their substantial fluctuation during exploration phases. Emissions of ozone-depleting substances as defined by the Montreal Protocol totaled 62 metric tons in 2011 (2010: 93 metric tons), while emissions of heavy metals totaled 3 metric tons (2010: 4 metric tons).

As our portfolio expands and production volumes increase, we remain committed to our goal of reducing the emission of air pollutants from our chemical plants. By 2020, we want to reduce absolute emissions by 70% in comparison with baseline 2002. In 2011, the decline was 60.5%; we reduced emissions to 33,807 metric tons (2010: 60.4%; 33,940 metric tons).
