If policy makers were smarter technocrats, they would know that passive cooling film technology exists now and can cool surfaces below ambient by rejecting sunlight and having high thermal emissivity (unlike metallic reflectors). Add this everywhere to reduce A/C and lower urban heat island effects. It’s basically performs optically like snow. Paint doesn’t work because it gets dirty too fast, films can incorporate anti-fouling tech. Delivery companies are already putting these on their vehicles (look at the top of UPS trucks in the US, if there is a giant white rectangle, that’s it).
