Algae Lamps from Shamengo.

French biochemist Pierre Calleja has created large-scale algae powered street lamps that can potentially absorb more than one ton of CO2 a year.

Algae lamps can charge up batteries during the day through their photosynthesis process that is driven by the sun and nutrients. This stored power is then used at night to power lights. Calleja’s lamps can also be illuminated artificially, such as in dark underground parking lots, where the algae go to work absorbing all the CO2 emissions from the cars. Above ground or in homes, they use natural daylight.

Maybe a forest of these algae lamps in every city might go a long way to replace all the CO2 absorbing trees that got cut down to make way for urban sprawl.
