Wine glasses in general and handmade wine glasses in particular have a carbon footprint. It takes energy to produce them and more energy to ship them around the world, because you are basically shipping air.
That is why Bottega del Vino Crystal donates enough money each year to the National Forest Foundation, to offset the carbon footprint of the glasses we produce, from our factory all the way to your door.
In terms of accounting, transparency, and efficiency, The National Forest Foundation receives a nearly perfect rating from Charity Navigator.
