According to the latest ABTA Consumer Trends Survey, 33% of holidaymakers believe holidays should have an environmental rating, up from just 29% in 2010.
The figure is even higher among women (38%) and those who take several holidays a year (49%).
The survey also found that 19% of holidaymakers would be prepared to pay extra for a holiday with a company that has a good environmental and social record.
Soren Stober, business manager for Travelife, a certification scheme that ranks the environmental and social practices of accommodation providers, said: "More and more people are expecting holiday companies to be both socially and environmentally responsible.
"Schemes such as Travelife can now meet the steadily growing demand for sustainably rated holidays."
Earlier this year, a separate ABTA study revealed that one in three people between the ages of 25 and 34 believe sustainability issues are important when booking a holiday.
