Hemp is a carbon-negative renewable resource.
Fossil fuel plastic is made from a non-renewable resource and emits significant greenhouse gasses during its lifecycle. Hemp, on the other hand, is a renewable resource that is actually carbon negative – it consumes far more greenhouse gasses than are emitted in its production. Just one ton of hemp can absorb up to 1.6 tons of CO2, making it one of the best carbon sequestration options on the planet.
Hemp production can be good for the planet.
In addition to being a “carbon negative” crop, hemp prevents soil erosion, can be cultivated over and over again on the same land and can even reduce water pollution.
