Whilst there is an expectation that new green jobs will be created as “brown” jobs go, this is often overstated. It is more likely that existing jobs evolve into “greener jobs” and existing skills sets become greener. In certain circumstances occupations may require more specific “green” skills sets but these are likely to be either top-up skills that enhance existing competencies but applied to new green technologies or ways of working, or more specific skills linked to emerging sub-sectors or fields.57 Table 7 provides an example of categorisation of green occupations in a selection of countries.
