While some may dismiss talk about environmental sustainability as a misguided or even bogus agenda for liberal activists, the economic reality is that "going green" means new, potentially lucrative coverage opportunities that carriers and brokers ignore at their own peril, leaders in this growing field contend.

For the past few years, several insurers have taken an active role in promoting environmental awareness and taking advantage of growth opportunities in this emerging exposure sector. Among the most prominent have been Allianz, Zurich, Swiss Re, American International Group and Travelers.

"We strive for exceptional financial performance and growth based on our commitment to the pursuit of a sustainable world, through combining long-term economic value, environmental stewardship and social responsibility," wrote Allianz in its "Sustainable Development Summary Report 2008."
