For companies trying to be sustainable and carbon neutral, warehousing and distribution can be difficult. It's fine to make green products, but it is more difficult to find a green way to get them into stores.
If you are serious about reducing emissions, and your product doesn't weigh too much, then this human-powered forklift may be a good option. You can move and lift pallets entirely with human power, and get that gas or diesel forklift out of your warehouse.
Although, it will only lift 30kg so it clearly isn't a replacement option for all companies. You raise the bed by turning a crank with your hand, and you transport the goods by pedalling with your feet. Quite a lot of forklifts are electric anyway though, so are fairly green to start with. ::Gizmodo
