"Cutting "70%-90% emissions" as if this object magicly appeared on location, no it's manufactured and needs to moved, recharged, etc..It is really time that we come up with a comprehensive footprint indicator, as of right now there isn't a widespread way of measuring that help everyone comprehend the impact, we should be able to compare it at purchase first and as we go.How are you planning to make people believe they're doing something positive when there's no evolving numbers to prove it ?!"
