Francesca Rheannon in "Sustainability Investment News" says that the book does not ask the most challenging question of all: is "clean growth" an oxymoron? She says that at a time when some experts say carbon emissions will need to be cut by 80 to 90% by 2050, the world may have to accept steady or even decreasing energy production, no matter how clean it is. Rheannon also states that there is little coverage of social issues. For example, nowhere is there mention of how water supply privatization and delivery by multinational corporations could affect the poor people of the world.
