For instance, the environmental goods and services (EGS) sector is estimated to be worth over USD 600 billion world wide and is projected to rise to just under USD 800 billion by 2015, with very positive impacts on employment (Selwyn and Leverett, 2006). Value added is mainly due to rent, interest and profit, however, implying that GDP data hugely overstate the benefits of this investment for the regions concerned, which depend mostly on wages. The impact on labour markets will depend on the job multipliers associated with the activities located in a given region. For instance, the stricter environmental regulation needed to encourage the use of renewable energy will probably act as a “job killer" in places specialised in conventional energy production, reducing the number of jobs in this sector.
