Everything that uses energy has an environmental impact, but using the Pure Outboard by far minimizes the overall environmental impact of a boat.
A Pure Battery Pack contains about 200g of cobalt, which is an environmentally unfriendly element to mine. But it replaces the use of about 2,000 gallons of gasoline in one outboard motor, which would cause the same amount of carbon monoxide, oxides of nitrogen, and hydrocarbon pollution as 430 cars over their entire lifetimes, in addition to 40 tons of CO2 pollution.
