Analysis of the spatial-temporal pattern and trend of carbon emissions provides an important scientific basis for the development of a low-carbon economy. Based on the corrected NPP-VIIRS and DMSP/OLS nighttime light data, a carbon emission model for the Chengdu-Chongqing Economic Zone (CCEZ) in China is constructed. Furthermore, the article establishes an integrated qualitative and quantitative research system.

Improving the green technology innovation capability of enterprises is an important way for industrial enterprises to improve product quality and production efficiency and reduce industrial pollution and energy consumption. Based on the Porter hypothesis, this paper took the data of listed companies of the heavy polluting industry in Chinese A-shares from 2011-2018 as a study sample, and a difference-in-differences (DID) model was constructed to explore the impact of environmental management system certification (EMSC) on enterprises' green innovation. This paper also studied the differential impact between the EMSC and enterprises' green innovation from the perspective of enterprise heterogeneity.

However, with proper treatment, these issues can be mitigated, turning large amounts of waste product into valuable resources and conserving energy resources. Based on this questionnaire survey conducted in the cities of Chengdu and Mianyang in Sichuan, China, this paper uses the value evaluation method to measure urban residents' willingness to pay for the treatment of gutter oil, and explores the factors and path influencing residents' willingness to pay based on the extended theory of planned behavior.

However, few studies concerned about the impact of energy efficiency label on consumers' purchasing behavior. Based on the theory of planned behavior (TPB), social cognitive theory and signaling theory, this paper constructs a theoretical model of the effect of the energy label on consumers' purchasing behavior of energy-saving household appliances.

Is it conducive to the sustainable development of the national economy? However, when most scholars study the impact of environmental regulations on companies performance, they have not classified companies performance. This article will study the relationship between environmental regulations and performance levels based on the classification of companies performance, and then divide the nature of industry pollution, companies location and nature of property for in-depth research.
Methods: First, this article uses a random effect variable-intercept model to measure companies financial performance and non-financial performance.
We report a case to provide an improved air quality index (AQI) based upon association between individual health risk and Particulate matter (PM) exposure. A Poisson sampling distribution model was used to quantify the health risk, in which the coefficient of exposure-response was derived from a simple Meta-analysis. The result shows that the old people are the most vulnerable population while exposing to PM, for which they are advised to reduce intensity of their physical activities.

Based on the panel data of 18 key provinces and cities between 2006 and 2015, this paper evaluated the agricultural carbon emission efficiency with the data envelopment analysis-Malmquist model and further explored their dynamic evolutionary trends. There were several main findings.

This study employed a data envelopment analysis (DEA) by using slacks-based measure (SBM) with undesirable outputs to assess the industrial environmental efficiency of western China during the period of 2001-2015. The Malmquist index was further used to examine the changes in the industrial environmental efficiency of the analyzed region. The result showed that western China presented a low industrial environmental efficiency throughout the period of 2001-2015.
