Via Oxford Mail: People can drive freely around their own neighbourhood and can apply for a permit to drive through the filters, and into other neighbourhoods, for up to 100 days per year. This equates to an average of two days per week. The alternative is to drive out on to the ring road and then back in to the destination. A maximum of three permits a household will be allowed where there are several adults with cars registered to the address.
"Why are we introducing trial traffic filters? Across our county, we want to reduce unnecessary journeys by private vehicles and make walking, cycling, public and shared transport the natural first choice. This will help us deliver an affordable, sustainable and inclusive transport system that enables the county to thrive whilst protecting the environment and making Oxfordshire a better place to live for all residents."
WaPo editorial board: 'This policy is a steadily rising carbon tax. A carbon tax would put a lower ceiling on national gasoline use without more aggressive regulatory interventions. It would also encourage every other piece of the economy to green up over time, starting with those for whom doing so is cheapest. This is why it is also the least expensive path to lowering the country’s carbon dioxide emissions. But a carbon tax would require Congress to act, which it has serially failed to do.'
