One single LED bulb could minimize greenhouse gas emissions by about half a ton. LED lighting can help the environment in different ways, they reduce greenhouse gas emissions which help having a smaller carbon footprint. Pricing is also a plus that would help lifetime operating savings of $1.4 trillion for commercial buildings and $3.2 for residential buildings. Along with the reduction of greenhouse gas emissions and the operating savings, they have longer lifetimes than other lighting, carbon dioxide emissions are low.
