Blockchain technology for a sustainable sea

Barcelona, June 29, 2023. Calculate and evaluate the capture of carbon dioxide (CO2) in the marine environment to enhance the sustainability of all activities related to the sea. This is the aim of the BlockchainxODS challenge in which the Sustainable Blue Economy Chair and the Tecnoambiente company participate. It is an initiative aimed at students and professionals from all sectors and the registration deadline ends on July 15 (www.blockchainxods.cat).

The new edition of the BlockchainxODS challenges is an initiative of CBCat (Centre Blockchain de Catalunya), promoted by the Barcelona Chamber of Commerce and the Generalitat de Catalunya. This year the challenges revolve are in line with Sustainable Development Goal 14, which aims to conserve and sustainably use the oceans, seas and marine resources for sustainable development.

These challenges encourage training in blockchain technology - a digital and decentralized record system based on a chain of interconnected blocks with coded information - and its subsequent application in projects to achieve the Sustainable Development Goals (SDGs) through a process cocreative Everyone who takes part in the challenges will receive a certificate attesting to their participation, and the members of the winning team will also receive attractive prizes, linked to the sea or new technologies.

Social justice and sustainable blue economy

"We seek to promote the sustainability of all activities related to the sea, of which there are many, taking into account three fundamental pillars: environmental, social and economic", explains Miquel Canals, professor at the Faculty of Earth Sciences and director of the Sustainable Blue Economy Chair at the University of Barcelona.

"Within the framework of the proposed challenge, we do so by connecting directly with the biggest problem facing humanity in our time: the global climate crisis", continues Canals. The oceans absorb - in different ways - huge amounts of CO₂ and heat, thus attenuating a global warming that would otherwise be unbearable. Through the proposed challenge, we want to evaluate the systems for calculating CO₂ absorption and, above all, propose mechanisms for certification and monetization of this process".

BlockchainxODS: Be part of the change

"We are looking for people from all areas and disciplines", explains Carles Agustí, coordinator of the CBCat BlockchainxODS project. "In fact, we try to make the working groups that will look for solutions to each of the challenges as multidisciplinary as possible. It doesn't make sense to make a group that only knows blockchain, but not law, or marine geology or biology, for that matter. That is why we address students and professionals who have a genuine interest in the challenges posed. Here everyone can contribute, and everyone adds up."

The IRBio members who will participate are:


The CBCat also promotes another challenge with the SUBMON organization which is included in the framework of the Horizon Europe SEA2SEE Project. It is an initiative to develop a tool based on blockchain technology to help consumers make informed and responsible decisions when buying seafood. "This challenge arises as a response to a need for clear information about sea products, since our daily actions directly affect the ocean", explains Juanita Zorrilla, head of projects at SUBMON.
