2012 has been a very dynamic and challenging year for the photovoltaic sector: The rapid cost reduction of photovoltaic power systems has continued throughout the year, leading to the emergence of new markets and market models. The market has continued to grow but at a slower pace than in the years before. At the end of 2012, about 100 GW of photovoltaics were installed worldwide, with contributions up to 6% of the electricity supply of some countries.

The goal of this report is to provide an understanding of global non-ferrous metal scrap flows in the context of non-ferrous industry developments over the 2000 to 2011 period. The focus of this study is on copper and aluminium as the two largest non-ferrous metals in terms of both material tonnages and market value. The report consists of four chapters. The first chapter, presented here, provides a brief backdrop to the analysis on non-ferrous scrap flows. It outlines growth in metal demand and the underlying reasons for this growth.

Under the umbrella of the Cement Sustainability Initiative (CSI) of the World Business Council for Sustainable Development (WBCSD), a number of leading cement companies are collaborating on monitoring and reporting greenhouse gas (GHG) emissions. One of these issues is the industry"s emissions of carbon dioxide (CO2), the main GHG contributing to man-made global warming. This revised Version 3 of the Cement CO2 and Energy Protocol is published in May 2011 and is intended to be applied for reporting of data starting in the year 2011.
