Abstract
Public provision of environmental information is becoming prevalent worldwide to improve public awareness of environmental risks to protect public health, but there is a lack of evidence on its effectiveness. This study examines how multiple interventions on air quality information will affect the attitudes, behaviors, health, and test scores of students in China.

Experimental Design

Experimental Design
We will conduct a survey experiment which randomly selects students in Chinese middle schools into multiple interventions. The interventions include basic information on ambient air quality at school, adverse impacts of air pollution, defensive measures against air pollution, and potential benefits and costs of defensive measures.
We measure multiple student outcomes before and after the experiment, including attitudes and behaviors, mental health and subjective well-being, and test scores.
