When we encourage to use electric vehicle we also need to consider that most battery are also naturally sourced material like lithium. Though we have credits associated to bicycle and walkscore criterions in reality these are not effectively used as an application front rather the points front alone its taken care at project level. However when we term sustainability we need to limit the vehicles including eletric vehicles such that we avoid carbon emissions and also there might be a chance for the project to provide shelters within the project premises for thier FTE/visitor counts. Since v5 is concentrating on carbon reduction as well. This course of action may really reduces the embodded carbon, limits the new manufacturing products in transportation. Even a small portion shall contribute to big level of emission reduction.
