Furthermore, the green growth poles are self-dynamic in nature, with catalytic and spillover effects, notably in terms of income generation, enhanced technological and skills capacity, as well as lower pressure on material/resource depletion and related resource pricing. However, in some areas (e.g. EE in end-use sectors and renewable energy equipment), additional investments will have to be made by a large number of small investors, for which viable financing arrangements/facilities should be made available.54 Furthermore, mobilization of private investment in poor developing countries will not be straightforward, and will likely require significant additional official development assistance and other foreign assistance, as well as foreign direct investment. Similarly, a group of companies, including Sony and Nokia, have created an “eco-patent commons” with initial donations of 31 EE-related patents.
