In recent years, China has made significant strides in combating environmental pollution and transitioning towards a low-carbon society. At the forefront of this movement is Ma Jun, the founding director of the Institute of Public and Environmental Affairs (IPE). Through innovative use of data transparency and community engagement, Ma Jun’s efforts have not only improved air and water quality in China but have also provided a model for other nations seeking sustainable growth.
A Decade of Change
A decade ago, Beijing was notorious for its heavy smog. On the worst days, residents could barely see buildings across the street, and flights were frequently delayed due to poor visibility. The annual average concentration of PM2.5—a key indicator of air quality—was nearly 90 micrograms per cubic meter. Fast forward ten years, and that figure has dropped to 30 micrograms in 2022. Major cities across China have seen an average decrease of 57% in PM2.5 levels.
The Role of Data Transparency
This remarkable improvement didn’t happen by chance. Ma Jun attributes the success to increased data transparency and public engagement. Recognizing that addressing pollution on such a scale required extensive public intervention, Ma Jun and his team began compiling corporate monitoring data into a database in 2006. Initially, they recorded around 2,000 cases of environmental violations. Over the years, this number grew exponentially, with enforcement records now topping 2.9 million.
In 2014, China mandated thousands of major polluters to publicly disclose their real-time emission data every one to two hours—a pioneering move globally. To make this information accessible, the IPE launched the Blue Map app. This innovative tool allows users to view emission records of factories across the country, share information on social media, and even tag local environmental agencies.
Empowering Communities and Companies
The Blue Map app color-codes factories based on their environmental performance—blue and green for compliance, red and yellow for violations. Initially, many factories appeared as red dots on the map, indicating non-compliance. However, the app empowered citizens to hold polluters accountable. Local environmental agencies began monitoring social media tags and addressing public concerns, urging violators to change their practices.
An illustrative example occurred in Shandong Province, a significant industrial hub. Ma Jun recalls meeting with the head of the provincial Environmental Protection Bureau. Instead of reprimanding him for highlighting polluters, the official welcomed the app as a valuable tool to garner public support in tackling pollution.
Extending Impact to Climate Change
While China’s air quality has improved, global greenhouse gas emissions continue to rise. Ma Jun believes that the lessons learned from combating air pollution can be applied to the fight against climate change. Recognizing that supply chains contribute significantly to carbon footprints, the IPE launched the Green Choice Initiative in 2007. This initiative encourages companies to use data-driven solutions to measure and disclose their carbon emissions and set reduction targets.
In recent years, many brands have begun utilizing digital accounting solutions to monitor their suppliers’ emissions. In the previous year alone, supply chain CO2 disclosures reached 62 million tons. This transparency enables companies to make informed decisions and promotes sustainable practices throughout the supply chain.
Global Recognition and Collaboration
China’s approach to environmental transparency has garnered international attention. The IPE has been invited to share their experiences with countries in the Association of Southeast Asian Nations (ASEAN), including Vietnam, Indonesia, Thailand, and the Philippines. Additionally, African non-governmental organizations have expressed interest in developing similar apps to monitor environmental performance on their continent.
Ma Jun emphasizes that in a globalized economy, environmental monitoring and supervision must also be globalized. By sharing data-driven solutions, countries can work together to prevent pollution transfer and promote sustainable growth worldwide.
Conclusion
The transformation of China’s environmental landscape underscores the power of data transparency and public engagement. Ma Jun’s journey demonstrates how access to information empowers communities, drives corporate accountability, and fosters policy changes. As nations worldwide grapple with environmental challenges, China’s model offers valuable insights into building a healthier, more sustainable future for all.
