The book provides an empirical analysis of the factors that determine the employment impact of environmental innovations. The multivariate estimations are based on a methodology taking direct and indirect employment effects on the firm level into account. The data are derived from interviews with more than 1500 firms in Germany, Italy, the Netherlands, Switzerland, and the UK specifically conducted for this analysis. In addition to the empirical study based on interviews, case studies from five selected business sectors are used to provide profound insight in the environmental innovation behaviour of the firms.
