Christine Todd Whitman, head of the US Environmental Protection Agency (EPA) under George W Bush, accused Mr Trump of ignoring compelling science.
And she warned that his threat to scrap climate protection policies puts the world's future at risk.
Trump supporters say rules on climate and energy are stifling business.
But Ms Todd Whitman says the US must find ways of promoting business without unduly harming the planet.
