How Web3 can help island nations fight climate change: Opinion

The cruel reality for small island nations across the Asia-Oceania region is their position at the tip of the climate change spear. Our collective march toward convenience and wealth at the expense of the environment has sea levels on pace to rise two-thirds of a meter by 2100. To put that in perspective, the countries of Kiribati and Maldives are estimated to be totally submerged by 2050. And that is not even to consider the impact of increasing weather events like cyclones.

In this absence of real commitment to sustainability, island nations have been left to fend for themselves. Rising sea levels are regrettable, say the large polluting nations, but are not nearly enough to warrant systemic change. It has left island nations searching for solutions to an existential problem. Namely, what can be done now to ensure, or at least prolong, the future existence of their homes.

Web3 has been offered up as a potential solution to the problem of climate change. It doesn’t have all the answers, to be sure, but it can be a useful tool. For island nations in particular, Web3 presents opportunities to issue revenue-generating climate assets, find new sources of funding for climate projects, and ultimately create a system of sustainable wealth transfer from the world’s biggest polluters.

On-chain climate assets as a revenue stream

The concept behind climate assets, such as carbon and renewable energy credits, is to incentivize regeneration, preservation and sustainability. And while the spirit behind the scheme is good, the implementation has created issues — the opacity and complexity of carbon markets, for one. Another is the cost associated with getting climate assets to market. These all add up to a supply shortage when corporate demand for carbon credits is at an all-time high.

Island nations are rich in climate assets — mangroves, rainforest, seaweed, seagrass, wind and sun. What they don’t have is a means to leverage the potential of those assets to meet global demand and create new revenue streams. This ultimately furthers the case for exploitation, a double-edged sword that both reduces a nation’s climate assets and puts it at even greater risk of rising sea levels and other climate events.

Web3 and its underlying technology are making it easier for island nations to leverage their climate assets. Carbon and renewable energy credits can be issued on-chain through asset tokenization, sold on a transparent voluntary market, and retired in a way that prevents fraud and double-selling. This process effectively turns climate assets into a legitimate asset class because once you have them on-chain, they are accessible by all and can be used in decentralized finance and regenerative finance
