Exploring environmentally responsible behavior of megaproject contractors using an extended theory of planned behavior.

Environmentally responsible behavior (ERB) of contractors in megaprojects is crucial for promoting sustainability, but how to trigger and predict it remains unclear. This study integrates moral identity and corporate green culture into the theory of planned behavior (TPB) to develop an extended TPB (ETPB). Based on a questionnaire survey (N = 181) from Chinese megaprojects, we found that (1) contractors' attitudes, subjective norms, and perceived behavioral control positively influence their intentions to engage in ERB; (2) perceived behavioral control, intentions, moral identity, and corporate green culture positively influence ERB; and (3) the explanatory power (R) and predictive power (PLS, CVPAT) of the ETPB model are superior to those of the TPB model.

Patterns of household concentrations of multiple indoor air pollutants in China.

Most previous studies on indoor air pollution from household use of solid fuels have used either indirect proxies for human exposure or measurements of individual pollutants at a single point, as indicators of (exposure to) the mixture of pollutants in solid fuel smoke. A heterogeneous relationship among pollutant-location pairs should be expected because specific fuel-stove technology and combustion and dispersion conditions such as temperature, moisture, and air flow are likely to affect the emissions and dispersion of the various pollutants differently. We report on a study for monitoring multiple pollutants--including respirable particles (RPM), carbon monoxide, sulfur dioxide, fluoride, and arsenic--at four points inside homes that used coal and/or biomass fuels in Guizhou and Shaanxi provinces of China.
