Less bad is not good enough: approaching zero emissions techniques and systems

Radical changes towards sustainable products and a clean and safe system of production have yet to be developed and implemented in all sectors of industry. Technology holds the key to addressing many environmental problems and achieving sustainable patterns of economic growth. In many cases, companies already have the appropriate technological solution. However, the technology may not be in widespread use because of market and systemic failures and cultural barriers. Examples of market failures are the lack of information about cleaner technologies. Examples of systemic failures are weaknesses in linkages among firms, universities, research and development (R&D) institutions, and others involved in developing, supplying and applying technology. Cultural barriers are caused by the differences in the way companies communicate and do business. This makes “zero emissions” a much needed approach. The Journal of Cleaner Production has devoted this special issue to “Zero Emissions Techniques and Systems – ZETS” in the production and the urgent issues surrounding, “How to make sustainable companies become reality”. To document the state of the art in this field and to report progress are main goals of this issue. The objective of the planners of this special issue is to present perspectives, case studies and pedagogic initiatives from, academic, governmental, business, technical and financial sectors, as well as from NGOs from around the world. It is, however, evident that the term “zero emissions” still has different meanings and refers to different strategies and technologies. “Zero Emissions Techniques and Systems” are really a “SYSTEMS” aspect and not a sectoral approach. It develops more and more like a discussion about a mosaic. Some speak of the image they expect to be seen at the end, others speak of the tesserae they have to shape or the cement that fills the gaps between.
