Blue Green Future (BGF) is proud to be part of team that just released the important article titled “Global distribution, quantification and valuation of the biological carbon pump,” published in Nature Climate Change on March 27, 2025, https://rdcu.be/efknr. The paper focuses on the role of the biological carbon pump (BCP), a crucial oceanic process that sequesters significant amounts of carbon, highlighting its importance for conservation, climate finance, and related policy considerations.
The BCP plays a vital role in the global carbon cycle by transferring carbon from the ocean’s surface to its depths, effectively reducing atmospheric CO₂ levels.
The article provides a comprehensive analysis of the BCP’s global distribution, quantifies the amount of carbon it sequesters, and discusses its economic valuation.
The article also estimates the economic value of the BCP at approximately $500 billion to $1.5 trillion USD in present value terms, depending on carbon market pricing and discount rates used.
Understanding these aspects is essential for informing conservation strategies and integrating the BCP’s value into climate finance mechanisms.
By emphasizing the significance of the BCP, the article underscores the need to incorporate oceanic carbon sequestration processes into broader climate policies and financial frameworks aimed at mitigating climate change.
Moreover, activities such as deep sea mining, commercial fishing, and bottom-trawling interfere with the BCP and thus reduce the ability of the ocean to help regulate climate.
