This is the saddest thing. Research reported in American scientific journal PNAS finds that right wingers are made less likely to buy an energy-efficient bulb when the purchase was specified as environmentally friendly than when it wasn't.
In the study, one of two carried out by Dena M. Gromet, Howard Kunreuther, and Richard P. Larrick, the researchers offered participants the choice of buying a conventional lightbulb, and an energy-saving one. Every participant was offered "information about the energy efficiency benefits of the CFL bulb compared with the incandescent bulb (e.g., the CFL bulb lasts for 9,000 more hours and reduces energy cost by 75%)," and the experiment was run twice, once with a realistic price difference (50¢ for the incandescent bulb, $1.50 for the CFL) and once with both bulbs at 50¢.
The participants were then split into two groups. One of the groups were given the CFL bulb in a blank box, the other in a box that said "Protect the Environment" on it. The result? Most people except those who were very left-wing were put off by the environmental label. Whereas slightly over half the people offered two blank boxes chose the CFL bulb, people offered the environmental label chose it 80% of the time if they were left-wing, dropping to just 30% if they were right-wing.
It's one thing to see that people on the left politically are more encouraged to protect the environment than people on the right – that's always been known – but it's an entirely different kettle of fish to discover that (American) right-wingers are actively turned off something if they discover it will help the environment. No wonder fighting climate change is so hard.
