• Financial instruments (shares, bonds, funds) only if issued, or sponsored, by environmentally and financially sound companies
• Physical assets (forests, renewable energy micro-generation power plants...)
• For the more sophisticated investor, derivative instruments such as emission allowances (aka “pollution rights”), green certificates etc. One should note that this is still a very young market, to be approached with extreme caution. However, the opening of the European Trading Scheme in February 2005, in the context of the Kyoto Protocol, has attracted a lot of attention, increasing volumes, and offers some opportunities (and risks).
