Abstract: Manufacturing processes, as used for discrete part manufacturing, are responsible for a substantial part
of the environmental impact of products, but are still poorly documented in terms of their environmental footprint. The
lack of thorough analysis of manufacturing processes has as consequence that optimization opportunities are often not
recognized and that improved machine tool design in terms of ecological footprint has only been targeted for a few
common processes. At the same time, a trend can be observed towards more energy intensive unconventional
processing techniques, so the impact of the manufacturing sector is in consequence growing steadily [1]. To address
these shortcomings, a worldwide consortium of universities and institutes recently launched the CO2PE!–Initiative
(Cooperative Effort on Process Emissions in Manufacturing) [2]. In addition to life cycle analysis, in depth process
analysis also provides insight in achievable environmental impact reducing measures towards machine builders and
eco-design recommendations for product developers. Influences of choices, made during the manufacturing stage, on
the impact of a product are indicated. In this paper, first an overview is given of the shortcomings in terms of the
coverage of production steps during LCA studies with existing tools. In a second part, the methodology used to
analyze manufacturing unit processes is summarized. Finally, some initial case studies conducted at the K.U.Leuven,
which allowed to identify significant improvement potential, are presented.
