Who we are
At NuWa Solutions, we’re dedicated to restoring balance to the planet through high-quality marine carbon dioxide removal (mCDR). Our work is based on transparent science, careful monitoring, and respect for coastal ecosystems and communities.
Our name is inspired by NuWa, a figure in Chinese mythology who repaired the heavens with stones. This story reflects our approach: taking practical, caring action to help fix systems that are out of balance. Today, our challenge is climate change and the ocean’s changing chemistry.
We work with the ocean to develop Ocean Alkalinity Enhancement (OAE) solutions that support its natural ability to absorb carbon dioxide. Simply put, we help the sea do what it already does, but more effectively and with clear safety measures.
Because OAE can reduce local acidification stress when thoughtfully designed, it can also support coastal resilience, especially in regions where acidification threatens fisheries, aquaculture, and marine habitats. In some settings, buffering can create conditions more favorable to biodiversity and sensitive life stages, such as those of shell-forming organisms. We treat these outcomes as potential co-benefits, not assumptions, and we design monitoring to evaluate them alongside carbon performance and environmental safety.
We approach OAE with both care and thoroughness. Every project includes measurement, reporting, and verification (MRV) along with environmental safeguards. This way, our progress is credible to buyers and regulators and accountable to local communities.

What We Do
Ocean Alkalinity Enhancement (OAE)
We advance OAE approaches that increase seawater’s buffering capacity in carefully controlled ways to enhance long-term CO2 uptake. Depending on the site and goals, this can involve small additions of carefully selected alkaline materials—including lime-derived alkalinity and mineral pathways—chosen for predictable behavior in seawater and low impurities.
MRV and environmental safeguards (integrated from the start, not added later)
We design monitoring around what communities, scientists, buyers, and regulators need to trust outcomes, including carbonate system measurements with robust quality assurance and quality control, clear safety guardrails, site-appropriate environmental monitoring, including biological indicators where relevant, and transparent reporting that supports credible claims and continuous learning.
Community-grounded project design
We aim to design projects together with local stakeholders, because the best climate solutions are those that communities can understand, shape, and trust.

Why NuWa
Science-led execution: We have strong expertise in ocean chemistry and carbon cycling, along with hands-on experience designing monitoring systems and practical workflows for the field.
High-integrity MRV: We focus on data quality, understanding uncertainty, and being transparent, so our results can stand up to careful review.
Responsible scale: We pursue approaches that can scale without cutting corners on safeguards, monitoring, or stakeholder trust.
Collaboration by default: We work with researchers, coastal partners, and project teams to create projects that are rooted in local needs and respected worldwide.
Our vision
To foster a sustainable future where oceans play a pivotal role in high-integrity carbon removal and environmental stewardship, supporting both global climate goals and healthier coastal waters.
Our mission
Through innovation, collaboration, and deep respect for marine ecosystems, we deliver measurable, verifiable, and scalable carbon removal solutions. Our work bridges marine chemistry expertise, field implementation, and real-world measurement, reporting, and verification to address urgent climate challenges without compromising environmental responsibility.
