The group cultivates relationships with governments and provides the necessary tools to help with the implementation of technology and new techniques. But often the solutions are far more sophisticated. In most cities, pavement and roofs together comprise over 60 per cent of urban surfaces. Akbari states that replacing 10 square metres of dark roofing with white roofing can offset one tonne of CO2.

In other words, the temperature reduction due to radiation not being absorbed by the earth is equal to the increase in temperature caused by one tonne of CO2 in the atmosphere, effectively balancing any change. By decreasing absorption of roofs by 25 per cent and pavement by 15 per cent, the overall temperature of a city can be reduced by two to three degrees Celsius.

Akbari points out that northern cities are ill equipped for heat waves, and for vulnerable populations, the consequences can be fatal. Recently at the Third International Conference on Countermeasures to Urban Heat Islands, held in Venice, Italy, in Octobermore than national delegates signed an agreement to promote the principles espoused by the Global Cool Cities Alliance in their home countries.

Akbari is particularly optimistic about the positive outcomes for Quebec if the province continues to implement his principles more widely.
