Policies to Reduce Vehicle Emissions around world


Air quality in Paris made policy makers go harder on diesel vehicle bans

So many cities around world have proposed or been implementing policies to curb private vehicle emissions. “Transportation, driven by rapid growth in car use, has been the fastest growing source of C02 in the world’ – Michael Replogie

Shanghai was an early adopter of license auctioning, an approach pioneered in Singapore in which residents bid to receive one of a limited number of license plates. Shanghai employed this policy in 1994 and kept conducting this policy until now. One thing needs to be noted is that the price of license plates in Shanghai is extremely high compared to the cost of buying a car or the annual maintenance fee, achieving $13,380 in July, 2015. However, Shanghai city invested what they gained from the auctioning to invest more on public transit expansion. Nowadays, Shanghai Metro owns the longest length 538km in the world.

In 2004, Beijing had about 2 million vehicles. By 2010, Beijing’s car ownership had skyrocketed to 5 million. In contrast to Shanghai, Beijing adopted a comparatively equitable lottery system, randomly awarding licenses to applicants. However, this system did lose the opportunity to improve public transit, also stimulated the black markets for illegal bidding proxy agencies.

Oslo has announced that it plans to ban private cars from the city centre by 2019. it is part of a plan to cut greenhouse emissions by 50%.

Paris started to conduct a temporary ban on cars last year. Cars with even-numbered plates couldn’t be used, and the effect was immediate: pollution fell by as much as 30% in some areas. In the future years, Paris will apply other restrictions on cars. Unless you live in a specific neighborhood, you won’t be able to drive around there on certain days.

Mexico City has tried to institute even / odd car days — cars with even license plates drive one day, and vice versa. Earlier this year, the city designated one Saturday a month to be car-free to give the the atmosphere a chance to clear.

Istanbul has pedestrianised over 250 streets on its Historic Peninsula, creating a car free environment that has improved air quality, reduced traffic congestion and improved pedestrian safety.

Rome has recently intoduced a parking ban in one of Rome’s most historical lanes in the city centre as the start of an ambitious plan to change the dominating car culture.
