Nowadays more and more intense discussions of professionals are carried out; they are focused on the issues of global warming. One of the latest documents in the fight against the climate change is the New Global Climate Agreement approved during the Climate Conference in Paris in December 2015. Although the signed agreement does not stipulate any timetable or particular targets for individual countries, it is nevertheless considered to have its impact on the individual spheres of economy, for which there are currently no mandatory environmental requirements. These results in the fact that the existing measures are not sufficient to achieve the objective of 40% reduction in greenhouse gas emissions by 2030 compared with 1990, to which the European Union has already committed itself [EC 2015]. Other measures thus may relate primarily to heavy industry, specifically to the area of machinery, which belongs among large energy consumers [Iskandirova et al. 2014]. The present article covers the assessment of environmental impact of greenhouse gas emissions on designing the machinery. The article describes a proposal of methodology for evaluation of emissions of greenhouse gases released in the production of engineering materials.
