Those who say that they care about climate change talk the talk, but don’t walk the walk, according to a UK government report. Participants who said that they worried about climate change used more energy than those who agreed that climate change is too far into the future to worry about.

Researchers monitored 250 households’ energy usage for a year and figured out that older respondents were more likely to say that they were not worried about climate change and also more likely to use less energy. But when the older households were removed from the picture, researchers still found that what participants said about their climate change worries had little effect on their consumption and footprint.

The report said that, “policy makers cannot rely on stated behaviors alone,” especially when, “the greater the concern people express about global warming, the less they do to reduce their energy usage.”

The U.S., on the other hand, has another issue. One in four Americans still believe that there is no solid evidence that global warming is a thing that is happening. But if the UK findings are true, and true across the Atlantic as well, then more climate change deniers may just be better for the environment after all.
