Half of corporate real estate executives are willing to pay extra for space in green buildings, according to the fourth annual Sustainability Survey conducted by CoreNet Global and Jones Lang LaSalle.

Conducted in the fourth quarter of 2010, the survey results reveal a corporate real estate industry in the process of reconciling the focus on reducing environmental impacts of buildings with the need to control costs and support corporate financial performance.

The report indicates that sustainability is a critical business issue today for 64% of respondents and 92% consider sustainability criteria in their location decisions. The number of respondents willing to pay more for green leased space jumped from 37% in 2009 to 50% in 2010.

Just over 30% of corporate executives ranked employee productivity and health as their top sustainability concern, and an additional 11% rated employee satisfaction as the most important factor.
