Our proposal in few words

• Green Zoning is a flexible method to halt the spread of the virus and restore safe mobilty within a single country or a group of countries.

• It is based in four key principles:

1. Divide each country into smaller zones (for example, states, regions, provinces, or economic commuting zones).

2. Label zones green or red based on common, objective criteria, depending on whether the virus is under control or not.

3. Adopt public health measures depending on the colour of the zones (and finer differentiations).

4. Allow travelling between green zones, but limit other travels as much as possible (for example, require a negative test, or a 7-day quarantine).

• Green zones form a safe network where life can progressively return to normal.

• Red zones, on the contrary, need to be managed carefully to halt the spread of virus and protect the population.
