In 2008, China launched the Green Securities Policy to increase sustainability practices among companies listed on Chinese stock markets. An integral component of the policy is the environmental disclosure regulation, which directs publicly traded Chinese companies in 14 highly polluting industries to report required environmental information. This research explores the Green Securities Policy in two ways. First, it determines the compliance level with environmental disclosure requirements from 2008 to 2010 by companies covered under the Green Securities Policy. The findings indicate that about 60% of listed companies report the required environmental information at some level. Second, the research examines the dynamics underlying environmental disclosure by Chinese listed companies through the lens of ecological modernization theory. While China’s ecological modernization has created an increasingly favorable environment for environmental disclosure regulation, the research highlights problems that have impeded the progress of environmental disclosure by listed companies.

ABSTRACT:Permafrost is sensitive to climate change. In recent decades, a growing body of research has focused mainly on the study of permafrost thaw, but leaving the climate change in the permafrost region that has not been adequately assessed, which is of first importance for the research on permafrost thaw. Using gridded observations from the Climatic Research Unit (CRU), in conjunction with the European Centre for Medium-Range Weather Forecasts Reanalysis Interim (ERA-Interim) and Japanese 55-year Reanalysis (JRA-55) data, this study investigates characteristics of air temperature evolution in the region of permafrost throughout the 20th century. Results show that yearly air temperatures in the permafrost region of the Northern Hemisphere experienced a statistically significant warming, with trends of 0.13 ∘ C decade −1 for 1901-2014 and 0.40 ∘ C decade −1 for 1979-2014. Winter air temperatures showed the greatest increase during 1901-2014, while autumn air temperatures increased the most during 1979-2014. In addition, increases in air temperature in high-latitude permafrost sub-region are greater than those in high-elevation permafrost sub-region, and air temperatures in the permafrost sub-region of Mongolia have the largest trend from 1901 to 2014, followed by those in Russia, Alaska, Canada, and China. Air temperatures in the permafrost region increased 1.7 times more than temperatures globally from 1901 to 2014, and underwent an increase at a rate of 0.32 ∘ C decade −1 during the period 1998-2014, when the global warming hiatus occurred with a trend of 0.06 ∘ C decade −1 . This implies that permafrost thaw may have continued during the global warming hiatus period. The close agreement between CRU data and ERA-Interim and JRA-55 reanalysis data indicates good reliability of air temperature evolution characteristics. These results provide information relevant to climate change in the permafrost region, and are useful for researching and understanding historical permafrost change.

Pakistan summer monsoon rainfall consists of a large portion of the local annual total rainfall, and in the recent monsoon seasons, prolonged periods of anomalous rainfall and excessive flooding have appeared in Pakistan. A full understanding of the monsoon rainfall variability is important for the sustainable development of the country. Based on multiple data analyses and the weather research and forecasting model, the potential impact of Tibetan Plateau (TP) heating on the interannual variability of Pakistan monsoon rainfall is investigated. It is observed that a significant negative relationship exists between the thermal forcing over the southeastern TP and Pakistan monsoon rainfall in July-August. Both the data analyses and model sensitivity experiments identify that the TP heating drives a Rossby wave response in the upper atmosphere characterized with an anticyclonic anomaly over the southern TP but a cyclonic anomaly to the north. This dipole pattern of anomalous circulation induces an evident upper-level convergence over Pakistan, corresponding with remarkable vertical sinking motion. Meanwhile, in the lower troposphere, the TP heating causes anomalous westerly wind along the Himalayas over the northern India continent. Such westerly anomaly further induces less water vapor transport into Pakistan from the Bay of Bengal. Therefore, both the dynamic and thermodynamic processes regulated by positive TP heating are not beneficial for the occurrence of monsoon rainfall in Pakistan. This study proposes a new potential mechanism in which TP heating acts as a driver of Pakistan monsoon rainfall variability on interannual time scales.
