Carbon Footprint?

That's called a lifecyle essment, and well done for thinking about it. The container is made from recycled plastic itself and is supposed to be used permanently - meaning there is no recycle/discarding stage in its life. So, the real question is how much environmental damage e.g. pollution did it take to make it to your house? I am not sure about that, but if you found out you could reduce your carbon emissions in other areas to compensate for the stages from its initial production to delivery on your doorstep.
