  • *1NOx (Nitrogen Oxides: Produced when a substance combusts and reacts with nitrogen in the atmosphere, or when fuels or substances containing nitrogen compounds, such as coal, combust.) They not only cause air pollution such as photochemical smog and acid rain, but have detrimental effects on human respiratory organs.
  • *2SOx (Sulfur oxides): Produced through the combustion of fossil fuels with sulfur content. Their reactions with moisture in the atmosphere produce sulfuric acid and sulfurous acid, making them a cause of both air pollution and acid rain.
  • *3Particulate Matter: The solid particles (soot) of the soot and smoke produced by fossil fuel combustion are a cause of air pollution and also pneumoconiosis in people who inhale them in high concentrations.

  • *Our company’s pay system is a so-called “Position Class System” which does not in and of itself give rise to gender pay differentials. One reason such differentials have nevertheless emerged is the comparatively low numbers of female managers, possibly due to female employees in their late-20s and 30s going onto the “Mommy Track” of childbirth and childcare. We shall respond to this going forward by increasing female manager numbers in order to narrow gender pay disparities.
