These 96 cities account for more than 20% of the global economy. The mayors of these cities plan to pass laws and offer incentives to have their plans accepted and implemented.

One can look at Oxfordshire, England, as an example. Oxford is a city in England in the county of Oxfordshire and is one of the 96 members of the C40 Cities. I chose Oxfordshire as an example because they have a detailed website available to anyone who wants to understand this concept better.

The structure of C40 Cities is also called 15-minute Cities. The concept here is that filters would be placed around the city to keep people within a 15-minute radius of their residences.

In their FAQ section on the council's website, it is explained how traffic filters work. These filters will not be physical road closures. Rather, they will be enforced by automatic number plate recognition (ANPR) cameras. Unauthorized vehicles going through traffic filters can therefore be identified. Any car that goes through the traffic filter that is not exempt will be issued a fine.

It was proposed that residents of Oxfordshire County will be issued 25 day passes per vehicle per year with a maximum of one car per person and two vehicles per household. Residents in the Oxford city permit area, who are most affected by the plan, would receive a maximum of 100 day passes per vehicle per year.

Oxfordshire County did open up the plan for public comments. The council received over 5,700 comments, of which 93% opposed traffic filters and only 7% supported them. Yet in November 2022, Oxfordshire County Council approved £6.5m for six traffic filters. (At the time, 6.5m pounds was equal it $8,306,350 dollars.) Leaders say traffic filters are intended to reduce traffic levels in Oxford by targeting unnecessary journeys by cars and will encourage walking, cycling, and using shared public transportation.

ESG – Who Cares Wins
You may have heard of the planned United Nations proposal Agenda 2030. Now it's best known as ESG. ESG stands for "Environmental, Social, and Government." The term was first used in a 2004 United Nations report entitled "Who Cares Wins; Connecting Financial Markets to a changing world."
