China's War on Pollution

2008 Beijing Olympics Context
- China's first Olympic Games hosted in 2008
- 10,000+ athletes from 200 countries
- 300 summer events
- Most watched televised event in history at the time
- Beijing's grand entrance to international stage
- $9 billion spent on public transit improvements
- Doubled subway size
- Buried ugly power lines underground
- Planted flowers, constructed 20 new buildings
- Bird's Nest stadium opening ceremony
- August 8th, 2008 at 8:08 PM (lucky number 8)
- 4-hour event cost $100 million ($7,000 per second)
- Weather manipulation: shot chemicals at sky with rocket launchers to clear rain
- Severe pollution problem during Olympics
- City covered in thick grey smog
- Air quality so bad athletes changed events or didn't compete
China's CO2 Emissions Perspective
- Per capita emissions comparable to Poland/Mongolia
- Much lower than US, UAE, Qatar
- Total emissions: 25% of world's emissions
- Population: 1.3 billion people
- World's largest car market
- 322 million motor vehicles (equal to US population)
- Pollution severity: stops planes from landing, visibility so poor can't see fingers
Vehicle Registration Restrictions
- Beijing, Guangzhou, Guiyang use lottery system
- Originally 1 in 783 chance of winning license plate
- Beijing reduced quota from 90,000 to 40,000 annually
- Current odds: 1 in 2,031
- Shanghai auctions license plates
- Average price: $14,022 (nearly 2x China's per capita GDP)
- More expensive than most cars themselves
- Corruption: government official arrested for accepting $30,000 bribes per plate
Driving Restrictions in Beijing
- Last digit of license plate determines driving days
- Numbers 1&6: no Monday driving
- Numbers 2&7: no Tuesday driving
- Numbers 3&8: no Wednesday driving
- Pattern continues, all allowed weekends
- Numbers rotate 4 times per year
- Violations: 3 points on license (12 points = suspension)
Air Quality Measurements
- Normal cities (LA, San Diego, southern China): 50-100 AQI
- Northern China: often 3-5x higher (150-500 AQI)
- Pollution kills estimated 1.6 million people annually in China
- Impacts tourism, visible in capital where politicians live
Electric Vehicle Revolution
- China buys more EVs than rest of world combined
- Millions entering middle class buying first cars
- No stigma against electric vehicles
- EV incentives:
- Exempt from last-number driving restrictions
- Separate license plate application line
- Many don't require driver's license
- Low-speed EVs: 40 mph top speed, cost $4,000-5,000 (vs $20,000-30,000 for smart cars)
- Tesla factory approved outside Shanghai
- All Shenzhen buses converted to electric
- Charging infrastructure doubled in last year
Coal and Energy Transition
- China burns more coal than India
- Three types of coal plants:
- Subcritical (low temperature, less efficient)
- Supercritical (medium efficiency)
- Ultra-supercritical (high temperature, most efficient)
- By 2020: all Chinese coal plants more efficient than US coal plants
- Limited natural gas reserves, moving directly to renewables
- Produces more renewable energy than any other country
- Renewable energy creates more jobs than fossil fuels
- Coal employs fewer Americans than Arby's fast food chain
Environmental Progress Results
- Beijing air pollution decreased 35%
- Could save 20 million residents 3 years of life expectancy
- 2018: overall car sales fell to 2-decade low
- Electric/hybrid cars continued growing despite economic slowdown
- US removing EV tax credits and environmental protections while China leads
