Plant 3m trees: Milan's ambitious plans to get city cleaner and greener

MILAN - If Italy's fashion capital has a predominant color, it is gray not only because of the blocks of neoclassical stone buildings for which the city is celebrated, but also due to its often-gray sky, which traps pollution.

But Milan now wants to shift its color palette toward green.

The city has ambitious plans to plant 3 million new trees by 2030, a move that experts say could offer relief from the city's muggy, sometimes tropical weather.
