Boston's current greenhouse gas reduction goals are to reduce emissions 25% by 2020 and 80% by 2050.
Based on what the City has achieved so far, a 25% reduction would be the equivalent of taking 140,000 homes off the grid or in one year - Boston has 275,000 households. Or, if one large commercial building was equal to a thousand households, it would be the equivalent of 140 large commercial buildings.
An 80% reduction is the equivalent of nearly 450,000 homes - more than the entire stock of homes in Boston. Or, around 450 large commercial buildings - also more than the stock of commercial buildings. Of course, reaching this goal would require that much of our energy use come from renewable sources.
