This review surveys five major efforts to identify and declare values essential to global sustainability; describes empirical trends (as measured by multina- tional and global-scale surveys) in values, attitudes, and behaviors related to human and economic development, the environment, and driving forces (population, affluence, technology, and entitlements); and describes empirical trends in attitudes toward contextual values that condition sustainable development (e.g., freedom and democracy, capitalism, globalization, and equality). Finally, the review identifies important barriers between attitudes and behavior; draws several conclusions regarding the value, atti- tudinal, and behavioral changes needed to achieve global sustainability; and suggests future research directions.
