NFTs are a kind of crypto asset that exploded in popularity last year, with a unique digital signature guaranteeing they are one of a kind. Other efforts to fund conservation via NFTs include plans for a South African wildlife reserve.
In Brazil, a company called Nemus on Friday began selling NFTs granting buyers unique sponsorship of different sized tracts of forest, with the proceeds going to preserve the trees, regenerate clear-cut areas and foster sustainable development.
Token holders will not own the land itself, but will have access to key information about its preservation, from satellite imagery to licensing and other documentation, said Nemus founder Flavio de Meira Penna.
He said Nemus had sold 10% of an initial offer of tokens for 8,000 hectares on the first day.
“My guess is this will accelerate rapidly in coming weeks,” Penna told Reuters, adding that blockchain technology would ensure transparency in the use of the funds.
Plots vary in size from a quarter of a hectare to 81 hectares (0.6 to 200 acres), which buyers will be able to locate with online maps.
NFTs for the smallest plots sell for $150 and the largest fetch $51,000, said Penna, who is hoping to raise $4 million to $5 million to buy an additional 2 million hectares of land already under negotiations in the municipality of Pauini in Amazonas state.
Along with preserving the forest, Penna said the funds would support sustainable development efforts such as harvesting acai berries and Brazil nuts by local communities in Pauini, which is the size of Belgium.
Each token comes with artwork of an Amazon plant or animal and is processed by San Francisco-based Concept Art House, a content developer and publisher for NFTs.
Critics have questioned the value of NFTs for environmental causes because tokens using the blockchain technology require intense computing power, driving up demand for electricity generation that releases climate-warming greenhouse gases.
Penna dismissed that view, saying preservation of threatened areas of the Amazon far outweighs the environmental cost of NFT transactions.
