A US study suggests that LGBT people are more concerned about the environment than their straight counterparts.

According to a poll by Harris, 55 per cent of LGBT adults say they “personally care a great deal about the current state and future of the environment,” compared with 33 per cent of heterosexuals,.

Furthermore, the survey found that 40 per cent of LGBT adults say they “encourage others to be more environmentally friendly”, compared with 24 per cent of straight people.

In other results, it was found that LGBT people were more likely in 2010 to say they were “environmentally conscious” than the year before. The opposite was seen in straight respondents.

Forty-seven per cent of LGBT adults described themselves as “environmentally conscious” in the 2010 survey, up from 38 per cent in the 2009 one. Twenty-eight per cent of straight people described themselves as such in 2010, down from 30 per cent in 2009.

The poll surveyed 2,352 adults in December, 347 of whom described themselves as LGBT.
