In 2011, our carbon dioxide emissions totaled 272,037 (296,972) tons. This includes CO2 emissions from our direct and indirect energy use (Scope 1 and 2). About 73 percent of our CO2 emissions are created indirectly when purchased electricity, steam and district heat are produced elsewhere. In absolute terms, total CO2 emissions have decreased, mostly due to decreased energy comsumption. Our production has also become more energy efficient, which can be seen in a decreasing CO2 emissions index.
Scope 3 emissions (e.g. employee travel and transportation) are currently not reported at the Group level and are not included in this report.
Most of our VOC emissions are created during the use of solvent-based chemicals in foundry and painting processes and in washing components. In 2011, our VOC emissions were approximately 421 (397) tons. The VOC total and the VOC emissions index should only be used as a guideline, as the figure is not comprehensive for all Metso production units.
