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.

1. Steigender Energiebedarf und ein Recht auf Kühlung? Darf es ihn geben, den Anspruch auf eine Klimaanlage und einen Kühlschrank – ähnlich wie das Recht auf eine Heizung? 2. Kühle Kette für eine gesunde Versorgung Nach Schätzungen der Weltgesundheitsorganisation (WHO) verderben durchschnittlich 30 Prozent, in tropischen Ländern sogar 50 Prozent der Lebensmittel mangels angemessener Lagerung. 3. Grüne Technik und Wertschöpfung Das Zauberwort heißt Ressourceneffizienz. Der Schlüssel in der Kältetechnik dafür sind natürliche Gase. 4.

Kühlschrank und Klimaanlage – sie stehen ganz oben auf der Wunschliste von Menschen in heißen Ländern. Bis zum Jahr 2030 rechnet die Internationale Energieagentur (IEA) mit einem viermal höheren Energiebedarf für Klimatisierung in den Entwicklungs- und Schwellenländern im Vergleich zu heute. Auch werden oft chemisch hergestellte Gase als Kühlmittel eingesetzt. Sie schädigen die Ozonschicht und treiben den Klimawandel voran. Grüne Technologien nutzen hingegen natürliche Gase zur Kälteerzeugung, sind energieeffizienter und können mit Sonnen- oder Windkraft betrieben werden.

Almost as much energy is used for refrigeration, air conditioning and insulation worldwide as for transport or heating. On behalf of the Federal Ministry for Economic Cooperation and Development (BMZ), the GIZ ‘Proklima’ project has now been working for some 15 years to help introduce environment- and climate-friendly alternatives to ozonedepleting industrial gases (such as chlorofluorocarbon, CFCs) in partner countries. Proklima thus supports developing and emerging countries in fulfilling their obligations arising from the Montreal Protocol on Substances That Deplete the Ozone Layer.

Initiated by the detection of the so called “ozone hole” over the Antarctic, the Montreal Protocol on Substances that deplete the Ozone Layer came into force in 1987. The Protocol regulates the phase-out of production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFC) in refrigeration and air conditioning. This phase-out has led to the introduction of new, environmental-friendly technologies in industrialized countries.

In 2015, global investment in renewables grew about 5 percent relative to the previous year and reached an all-time high of US$ 286 billion (bn). And there are more interesting trends: Investment in renewables’ based electricity generation capacity in 2015 has been more than double the investment in the major fossil fuels (renewables: US$ 266 bn versus US$ 130 bn for coal and gas stations). This also leads to added capacity in terms of Gigawatts in 2015 in renewables (134 GW) outstripping all other technologies combined (conventional coal, gas, and nuclear).

Effective responses to climate change require efforts by both the public and private sectors to develop and disseminate new environmentally sound technologies (ESTs) on a global scale, as well as to adapt them to local needs. However, due to a number of market failures and specific uncertainties, the spread of green technologies is less than optimal, which necessitates additional incentives. Based on a review of recent literature, the present Global Challenges
