Recently, it has been possible to observe toughening of requirements to reduce environmental burden and environmental profile of products. While the first requirements were rather general, in the course of time they have toughened and focused on spheres that most considerably affect the environment, namely, on energy-related products. According to high energy consumption in the industrial sector, an increase of legislative requirements for engineering products is also expected. Currently, majority of environmental legislation also apply to engineering products. This development should draw an attention of machinery manufacturers to the changes planned for the near future that they can also be concerned with. The present article is devoted to the development of methodology for evaluation of environmental burdens caused by greenhouse gas emissions (in this case it is carbon dioxide) arising from production of engineering materials (e.g. cast iron); from mining and processing of raw materials to casting and transporting of finished product to the site of its subsequent processing.
