Well sort of. The battery charger for this cordless electric mower is energy star qualified.

Qualified battery charging systems use, on average, 35% less energy when charging a battery than similar conventional models. How do they do this? The charger is smart enough to know when the battery is done charging and reduce its power draw accordingly. According to the Energy Star organization conventional battery chargers can be quite wasteful – drawing as much as 5 to 20 times more energy than is stored in the battery.

Until now we have only considered hand push lawn mowers green enough to be in our catalog. Electric mowers, while not emitting point-source pollution, were not going to convert over gas mower users who need the freedom from cords. And cordless electrics are generally underpowered and wasteful of electricity during the charging process. However, this new Energy Star Qualified Black & Decker CMM1200 cordless mower seems to be a step in the right direction and we have decided to include it in our lawn mowers section.

It also got some pretty good usability ratings — check out the consumer reports article on it.
