Traffic management

Jamie Learner made a new intergrated traffic system (the use of buses).
There are triple articulated buses to reduce the number of people using cars and damaging the environment.
It is very efficient (comes every 60s).
The transport system funds itself as 2 million people use it per day.
Employers subsidises their employees to use it.
There are more pedestrianised areas built to enourage more walking.
No one lives more than 400m from a bus stop so it is easy to commute everywhere.
80% of travellers use this system. This means that the CO2 emissions are significantly less and they can live in a more sustainable lifestyle.
Walking and cycling are safe.

Air pollution management

Reducing the amount of vehicles used reduces the amount of greenhouse gases emitted.
Lots of parks are being created to be able to absorb more of the CO2. In total, the is 12 acres per 1000 people.
The parks also allow people to walk to work and create leasure facilities.
At the roof of flats, plants are planted there to absorb more of the pollutants.
