The industry sector is an important direct and indirect source of greenhouse gas (GHG) emissions in Annex I countries. Emissions from the industry sector are expected to draw increasing attention by policymakers as they look for means to reduce domestic GHG emissions. For this reason, the Annex I Expert Group (AIXG) on the UNFCCC decided to hold a workshop in Berlin on 2-3 December 2002 to discuss the range of policies to reduce GHG emissions in industry, with a focus on voluntary approaches (VAs), taxes and trading. The overall aim of the workshop is to assess experience and identify and promote successful approaches, "good practice" and lessons learned to date. The policies cover both GHG emissions from energy use in industry and GHG emissions from industrial processes.
