Short-term measures to improve air quality
In preparation for the 2008 Olympic Games, China implemented a series of short-term measures to improve air quality in Beijing and the surrounding areas. These measures were taken to ensure a "Green Olympics" and were in place for several weeks before, during, and after the games. Here are some of the key short-term measures:
- Temporary closures or production reductions at polluting plants: Chemical and cement factories near Beijing were shut down temporarily, including major polluting plants such as the Beijing Dyeing Plant and the Beijing Coking Plant.
- Traffic control: The number of cars on the roads in Beijing was reduced by half during the Olympic period. This significantly cut vehicle emissions and improved air quality.
- Holiday for government organizations: During the 2014 APEC Summit in Beijing, employees of government organizations and institutions were given a six-day holiday, which reduced traffic and improved air quality in the city. However, this measure added traffic and pollution to surrounding areas and was only a temporary solution.
- Emissions standards: Tougher emissions standards were imposed on coal-fired plants, and coal-fired boilers in homes were replaced with gas or electric heaters.
- Local targets: Local officials were given specific environmental targets to work towards, encouraging a collective effort to improve air quality.
These short-term measures were successful in bringing about a rapid improvement in air quality for the 2008 Olympic Games, with Beijing experiencing a 29.6% reduction in air pollution during the games compared to the previous year. However, it is important to note that these measures were intensive and costly, and longer-term, more sustainable programs were later implemented to continue improving air quality gradually.

Long-term environmental protection programs
The Beijing 2022 Winter Olympics has been touted as the "greenest and cleanest ever" by China and the International Olympic Committee (IOC). However, many experts and activists have criticised the host city for unsustainable practices, particularly in the context of China's broader environmental issues, such as its reliance on coal-powered energy.
To address these concerns, Beijing 2022 released a Pre-Games Sustainability Report, outlining various long-term environmental protection programs. The report followed three international standards: the ISO 20121 Event Sustainability Management System, the ISO 14001 Environmental Management System, and the ISO 26000 Guidance on Social Responsibility. Here are some key programs and initiatives from the report and other sources:
- Carbon Neutrality: Beijing 2022 committed to staging carbon-neutral Games by implementing measures to reduce carbon emissions. This included the use of low-carbon venues and transport solutions, and natural CO2 refrigeration systems in ice venues, which are more energy-efficient than traditional methods.
- Green Energy: All venues were powered by green energy, a first in the history of the Olympics. This included the use of renewable energy sources and hydrogen-powered vehicles.
- Afforestation: Beijing and Zhangjiakou planted tens of thousands of hectares of forests and green areas. While this was promoted as a carbon offset measure, some experts questioned its efficacy and the potential impact on biodiversity.
- Sustainable Land Use: The site layout for the Olympics was designed to minimise construction and damage to the natural environment. The Olympic transportation design also considered sustainability, benefiting the Beijing-Tianjin-Hebei coordinated development.
- Water Conservation: Beijing suffers from water shortages, and the Games aimed to address this by prioritising water-saving measures in venue design and construction.
- Waste Management: Beijing implemented a sustainability management system with scheduled meetings, on-site inspections, and third-party reviews to ensure compliance with sustainable development goals.
- Legacy Infrastructure: The long-term objective is to create a positive societal impact and promote sustainable development. Beijing plans to convert Olympic venues into permanent ski resorts, with the potential for continued environmental impact.
- Wildlife Protection: Environmental Impact Assessments (EIAs) were conducted for the new competition zones, and wildlife was protected through restrictions on night-time construction, the establishment of wildlife corridors, and the transplanting or protection of plants.
These long-term environmental protection programs aimed to reduce the ecological impact of the Beijing 2022 Winter Olympics and create a positive environmental legacy. However, the effectiveness of these programs has been debated, and some critics have accused Beijing of ""greenwashing".

Air pollution control programs
In the years leading up to the 2008 Beijing Summer Olympics, China had been experiencing a sharp increase in air pollution. The Chinese government responded with quick reforms and temporary measures to reduce pollution during the games. These included shutting down some chemical and cement factories near Beijing and reducing the number of cars on the roads. While these measures were successful in improving air quality during the Olympics, they were not enough to bring about long-term change.
Recognizing the need for more sustainable solutions, China shifted its focus to long-term environmental protection programs after the 2008 Olympics. Beijing, in particular, implemented a series of comprehensive air pollution control programs. These programs included encouraging the use of natural gas instead of coal, closing down major polluting industries, improving supervision at construction sites, and upgrading coal-burning boilers. The city also adopted more stringent emission standards, leading to the retirement of high-emission vehicles and the renovation of buses and taxis.
One notable initiative is the Beijing Clean Air Action Plan, which ran from 2013 to 2022. This large-scale program aimed to address polluting industries, increase green energy generation, reduce traffic-related emissions, and restore barren land through reforestation. The plan contributed to a significant improvement in Beijing's air quality, with the average daily Air Pollution Index 36% lower during the 2008 Olympics compared to the previous eight years.
China's efforts to combat air pollution have had notable results, with US academics finding that China is responsible for over 70% of global reductions in airborne pollutants over the last seven years. However, challenges remain, as pollution levels in 2020 were still above the World Health Organization (WHO) guidelines. In preparation for the 2022 Winter Olympics, China continued its rapid actions to reduce pollution further and sustain these improvements.
Overall, the Olympic Games served as a catalyst for China to implement air pollution control programs and raise environmental awareness among its population. While short-term measures were initially successful, the shift towards long-term sustainability has led to more significant and lasting improvements in air quality.
