Google is putting more than $6 million behind a new research push designed to solve some of the hardest technical problems in carbon removal and superpollutant abatement. The initiative targets technologies that could eventually operate at gigaton-scale carbon dioxide removal and megaton-scale pollution reduction, placing research bottlenecks alongside procurement as a central part of Google’s climate strategy. The 2026 Google Carbon Removal and Superpollutant Elimination R&D Awards will distribute grants ranging from $350,000 to $500,000 across a portfolio that spans oceans, engineered carbon capture, biomass, land management and methane. Reilly O’Hara, senior program manager of carbon removal at Google, said the awards will target “critical scientific bottlenecks to unlock carbon removal at the gigaton scale and superpollutant abatement at the megaton scale.”

Google Targets Carbon Removal Bottlenecks

The funding portfolio reflects Google’s focus on scientific and engineering bottlenecks that currently constrain the development and scaling of carbon-removal technologies. Google’s awards therefore spread capital across multiple approaches rather than concentrating the program around a single removal technology. Ocean alkalinity enhancement receives some of the largest allocations, including as much as $450,000 for field trials that examine environmental and ecological consequences. Another $400,000 track will investigate whether ocean alkalinity approaches can expand beyond coastal outfalls, a question that matters if the technology eventually needs to handle removal volumes measured in hundreds of millions or billions of tons. For investors and infrastructure developers, the significance lies in what happens after the research stage: technologies that demonstrate credible performance in real-world environments can become substantially easier to evaluate for larger capital commitments.

Engineered carbon capture receives another significant portion of the program, with Google directing funding toward technologies that could reduce the energy and materials burden associated with capturing carbon dioxide. One research track offers up to $400,000 for next-generation capture systems designed for bioenergy facilities, with a particular focus on solid sorbents and metal-organic frameworks. The research will examine solid sorbents and metal-organic frameworks as next-generation capture materials, with the program targeting improvements that could reduce the energy required for regeneration. A separate track offers as much as $450,000 for research into the energy requirements of capturing low-concentration carbon dioxide, addressing a challenge that becomes increasingly difficult as CO2 concentrations fall. The distinction matters because carbon-removal economics depend heavily on how much energy and equipment a process requires for every ton removed.

Biomass Projects Expand the Removal Portfolio

Google is also backing pathways that connect carbon removal with waste management, agriculture and ecosystem restoration. Biochar research focused on difficult, high-moisture waste feedstocks can receive up to $450,000, targeting a segment of biomass that can create technical problems for conventional production processes. The program also allocates up to $350,000 toward mangrove restoration strategies designed to withstand rising sea levels, while land-use optimization for nature-based removal projects can receive as much as $400,000. These categories highlight a broader issue for nature-based carbon removal: the carbon accounting does not end when a project stores carbon. Long-term resilience, competing land uses, ecological changes and climate impacts can all determine whether the claimed removal remains durable. Google Climate & Sustainability will separately collaborate on perennial crop systems, with as much as $400,000 available for each of two projects, creating a potential $800,000 allocation.

Methane occupies a different position in Google’s climate portfolio because reducing emissions can influence near-term warming far more rapidly than removing carbon dioxide from the atmosphere. The awards include as much as $500,000 for systems designed to address diffuse methane emissions using photocatalytic and thermocatalytic approaches. Another $500,000 will support work with Spark Climate Solutions to improve constraints around atmospheric methane lifetime, while a further $450,000 will support validation of methane models at small-scale landfill sites. Those projects address different layers of the same problem: identifying emissions, understanding atmospheric behavior and determining whether mitigation technologies work outside controlled environments. Google is also working with Spark Climate Solutions on tidal wetland restoration frameworks, offering up to $450,000 for research that weighs carbon sequestration against methane emissions. The trade-off is important because wetlands can store substantial carbon while also producing methane under certain conditions.

Open Call Broadens Google’s Climate Bet

Beyond the named research tracks, Google has opened the program to proposals aimed at other critical bottlenecks in carbon dioxide removal and superpollutant abatement. The open call covers methane, nitrous oxide, ozone-depleting substances and fluorinated gases in addition to carbon dioxide removal. Individual projects can receive as much as $450,000, giving researchers an opportunity to pursue ideas that do not fit neatly into the predefined categories. This structure could prove strategically important because some of the most consequential climate technologies may emerge outside today’s dominant removal pathways. It also creates a mechanism for Google to identify technical opportunities before they become obvious to the broader market. The listed priority areas carry maximum awards totaling approximately $6 million, while a separate open call offers up to $450,000 for a single additional research project.

Google’s research strategy sits alongside a growing role as a buyer of carbon-removal credits, giving the company exposure to both the technology-development side and the procurement side of the market. The company recently agreed to purchase 260,000 tons of carbon-removal credits from Thryve.Earth for an agroforestry reforestation project in Sulawesi, Indonesia. Google made that purchase through the Symbiosis Coalition, a carbon-buying consortium formed in 2024 with Meta, Microsoft and Salesforce to support nature-based carbon removal. The transaction adds another corporate purchase commitment to a carbon-removal market in which companies are using long-term offtake agreements to support nature-based removal projects. Research funding addresses technical and scientific challenges before the technologies move toward wider commercial deployment. Google’s procurement agreements give selected removal projects a contracted buyer, including long-term purchases such as the 10-year Thryve.Earth agreement. Together, those mechanisms create a feedback loop between technological progress and market demand.

Biochar Deal Adds Another Layer

Google has also committed to biochar-based carbon removal through an agreement with Commonwealth Sortation to purchase 200,000 removal credits by 2030. The deal adds a waste-derived pathway to Google’s portfolio, with AMP’s project designed to collect organic waste from municipal landfills and convert it into biochar. Biochar can potentially connect waste management with carbon removal, but its climate value depends on feedstock characteristics, production methods, storage conditions and rigorous accounting. That makes research into high-moisture waste particularly relevant to the broader commercial picture. If researchers can improve processing efficiency and demonstrate durable carbon storage, a category that currently depends heavily on project-level execution could become easier to scale. Google’s research awards and purchasing agreements therefore operate on complementary timelines, with research addressing technical uncertainty while procurement creates an early market for technologies that meet credible performance standards.

The more consequential feature of Google’s initiative is not the headline dollar figure but the breadth of research areas the company is supporting across carbon removal and superpollutant abatement. Carbon removal requires technologies capable of moving from laboratory validation to field deployment, standardized measurement and ultimately industrial-scale operations without allowing costs or environmental trade-offs to rise faster than removal volumes. Google’s portfolio touches nearly every point along that chain, from ocean experiments and engineered capture materials to methane modeling, waste-derived biochar and resilient ecosystems. Google is combining R&D funding with carbon-removal purchases, giving the company activity on both the research and procurement sides of the emerging removal market. At the same time, the diversity of the awards spans ocean-based, engineered, biomass, land-based and methane-focused approaches, reflecting the range of pathways Google is supporting through the program.

From Climate Procurement to Climate Infrastructure

Google’s latest move expands the role of corporate climate spending beyond carbon-removal purchases to include direct support for research and technology development. The company’s carbon-removal purchases establish demand, while its R&D awards seek to improve the technologies that could eventually satisfy that demand at materially greater scale. The combination matters because Google’s R&D program directly targets scientific and engineering bottlenecks while its procurement agreements support the deployment of specific removal projects. Research institutions need capital to test uncertain ideas, developers need evidence before scaling projects and buyers need confidence that future credits will represent measurable climate benefits. Google is attempting to connect those stages through a funding model that treats research as a strategic component of the carbon-removal market. The $6 million initiative therefore looks less like a conventional corporate climate donation and more like an early-stage bet on the technologies that could underpin the next generation of carbon infrastructure.
