The British Tories are running around like headless chickens trying to jump on any policy bandwagon that'll attract the populist vote - and that includes the many Green issues. But we all know they ll "promise you the Earth", but deliver next to nothing that will be properly Green because to be remotely Green isn't in most business interests unless the consumer influences them - not the Tories. So no. Blue is NOT the new Green
The LibDems have always had a leaning toward Greenism, so that's not the new Green either.
