Environmental performance rating and disclosure - China's green-watch program
This paper describes a new incentive-based pollution control program in China in which the environmental performance of firms is rated and reported to the public. Firms are rated from best to worst using five colors-green, blue, yellow, red, and black-and the ratings are disseminated to the public through the media. The impact has been substantial, suggesting that public disclosure provides a significant incentive for firms to improve their environmental performance. The paper focuses on the experience of the first two disclosure programs, in Zhenjiang, Jiangsu Province and Hohhot, Inner Mongolia. Successful implementation of these programs at two very different levels of economic and institutional development suggests that public disclosure should be feasible in most of China. The Zhenjiang and Hohhot experiences have also shown that performance disclosure can significantly reduce pollution, even in settings where environmental nongovernmental organizations are not very active and there is no formal channel for public participation in environmental regulation.Environmental Economics&Policies,Public Health Promotion,Decentralization,Water and Industry,Health Monitoring&Evaluation,Environmental Economics&Policies,Water and Industry,Health Monitoring&Evaluation,National Governance,Health Economics&Finance
Object Detection in Foggy Scenes by Embedding Depth and Reconstruction into Domain Adaptation
Most existing domain adaptation (DA) methods align the features based on the
domain feature distributions and ignore aspects related to fog, background and
target objects, rendering suboptimal performance. In our DA framework, we
retain the depth and background information during the domain feature
alignment. A consistency loss between the generated depth and fog transmission
map is introduced to strengthen the retention of the depth information in the
aligned features. To address false object features potentially generated during
the DA process, we propose an encoder-decoder framework to reconstruct the
fog-free background image. This reconstruction loss also reinforces the
encoder, i.e., our DA backbone, to minimize false object features.Moreover, we
involve our target data in training both our DA module and our detection module
in a semi-supervised manner, so that our detection module is also exposed to
the unlabeled target data, the type of data used in the testing stage. Using
these ideas, our method significantly outperforms the state-of-the-art method
(47.6 mAP against the 44.3 mAP on the Foggy Cityscapes dataset), and obtains
the best performance on multiple real-image public datasets. Code is available
