Within the corrugations of the Life Box, which can be used for posting items, are hundreds of tree seeds and thousands of beneficial spores of mycorrhizal fungi.
Once a customer receives the parcel, the box is torn up and planted for tree seedlings to emerge, said American researcher, inventor and entrepreneur Stamets.
"After two years baby trees are planted about 30 feet apart. Of the hundreds of seeds in each box, if only one survives for 30 years, around one tonne of carbon is sequestered," he claimed.
The potential for coverage with trees coming from Life Boxes was 10,000-10 million hectares per week, Stamets maintained.
"The beauty of the box is that it adds negligible weight to the parcel and empowers individuals to offset climate change by planting trees."
Ten trees in each box, made of recycled cardboard and soy-based inks, include birches, alders, pines, hemlocks and cedars.
