Jelaskan "Cold Start" emissions dari Hutan bandar dalam bahasa melayu

The volatile components of asphalt pavement evaporate more slowly in shaded parking lots and streets.  The shade not only reduces emissions, but reduces shrinking and cracking so that maintenance intervals can be lengthened.  Less maintenance means less hot asphalt (fumes) and less heavy equipment (exhaust).  The same principle applies to asphalt-based roofing.
