Web3 sector has made significant progress in altering the climate discussion, according to an executive.
Transitioning to proof-of-stake (PoS) plays a role in reshaping the perception of blockchains as detrimental to the environment; however, there are still numerous actions that the Web3 ecosystem can undertake to address climate change, as stated by Marek Olszewski, the CEO of Celo, an Ethereum layer-2 scaling solution.
Cointelegraph editor Zhiyuan Sun engaged in a discussion with Olszewski regarding the challenges posed by climate change, the advantages of utilizing blockchain-based systems for carbon offsets, and various methods through which projects can mitigate their carbon emissions.
Olszewski noted that as climate change continues to pose a risk to humanity, organizations and initiatives are increasingly aiming for carbon neutrality. He remarked:
“Climate change is still a systemic threat to our species. I think as a society we kind of owe it to ourselves to do anything that we can. And I suspect that every project and every company in the next ten years will probably move to be carbon neutral.”
The Celo executive is of the opinion that the wider Web3 ecosystem has been making “really good strides” in altering the narrative regarding blockchain’s environmental impact. Last year, the community marked the Ethereum Merge, which represented the blockchain’s transition from the energy-intensive proof-of-work (PoW) consensus to the more eco-friendly proof-of-stake (PoS) mechanism.

Olszewski believes that the Merge, along with the initiatives from various teams within Web3 to offset or commit to reducing their carbon footprints, benefits the sector in two significant ways. Firstly, it draws in individuals who were previously deterred by arguments against the environmental sustainability of blockchains. Secondly, the executive emphasized that this fosters innovation within the regenerative finance (ReFi) ecosystem.
“At the very least, I think we’ve started to shift the narrative, which I think is both really good for the crypto industry because I think it pulls more people in […] and it’s created a safe space to innovate within the ReFi ecosystem,” Olszewski stated.

In addition to these points, the executive highlighted several advantages of implementing an on-chain carbon offset system as opposed to conventional methods. Olszewski pointed out that traditional carbon credit systems suffer from a lack of transparency. He explained that blockchain technology allows for real-time transparency and verification of the validity of carbon offsets. He stated:
“Being able to tie satellite data through an oracle on-chain, you can bring that information and see with certainty that the carbon offsets are doing what they claim they would do.”
When queried about carbon credits and how blockchain-based initiatives can reduce their carbon footprint, the executive provided several examples. Olszewski mentioned that in addition to tree planting, which is a common method for offsetting carbon emissions, other approaches include restoring habitats for species, direct air capture sequestration, and utilizing biochar as alternative methods for carbon offsetting.
