“The goal is net zero, which is a balance between the emissions we put into the air and the emissions we take out….We have solutions and…it’s not that the technologies don't work, it's not that we don't know how to use them. It's because we haven't made the choice to actually use them at the size and scale that we need to, as quickly as we want to, to avoid all these really terrible, terrible impacts of a changing climate.” Melissa Lott on Electric Ladies Podcast.
