‘Overall, the Handbook is a valuable resource. It provides a detailed and probing analysis of various facets of the investment-environment relationship, despite some chapters being slightly editorial. The Handbook’s key added value is its analysis on investment and environmental law regimes. More generally, while the Handbook provides certain analysis focussed on reconciling investment and environmental law protections it is largely limited to a lex lata analysis, rather than providing a lex ferenda vision for how investment and environmental norms, principles, and treaties may be harmoniously applied or interpreted. In this regard, scholars and academics searching for strong base material in these areas will find the Handbook useful, but the Handbook, for the most part, does not go on to chart new territory on investment and environment. Given the rapid acceleration of investment into environmentally sensitive or environment adjacent projects the investment environment nexus will surely continue to grow and the Handbook provides an overall solid starting place for those seeking to understand the legal relationship between the two regimes.’
