Top Carbon Startups in 2027

Planet Alpha Corp. (“PαC”) is a carbon measurement infrastructure, carbon securities and carbon products company integrating multiple Earth, economic and social transactions to reduce emissions of CO2 and greenhouse gases (GHG) to benefit landowners, investors and the planet. We do good by directly supporting landowners for their reduction of CO2 emissions through forest growth and management resulting in a performance-linked GHG economy positioned for business growth and return on investment. PαC creates a new forest carbon business paradigm that pays landowners and Indigenous People, upfront and annually, for directly measured carbon sequestration and sustainable management over the lifetime of the project covering decadal intervals up to 100 years.

Coastal Carbon is a seed-funded startup on a mission to create positive impact through earth observation and AI. Founded at the University of Waterloo by a team of PhDs and engineers, we’re backed by some of the best AI and climate tech investors like HF0, Inovia Capital and Propeller Ventures, angels like James Tamplin (cofounder Firebase) and Sid Gorham (cofounder OpenTable, Granular), and partners like Amazon AWS and the United Nations. We’re building multimodal foundation models for the natural world. We believe there’s more to the world than the internet + more to intelligence than memorizing the internet. Our models are trained on satellite remote sensing and real world ground truth data, and are used by our customers in nature conservation, carbon dioxide removal, and government to protect and positively impact our increasingly changing world. Our ultimate goal is to build AGI of the natural world.

Avnos is the world’s best shot to get to gigaton scale of carbon removal from direct air capture. We empower any company committed to decarbonization – from energy companies to carbon utilization to project developers — to remove carbon dioxide using fewer natural and financial resources when compared to other DAC companies. Avnos’ technology produces water — the world’s most valuable and scarce resource — and a key benefit to communities across the globe whose access is changing. Because it is geographically-flexible, Avnos’ technology has a broader operating range making it scalable in markets across the globe. We are a driven team of scientists, engineers and technical operators working together to solve one of the most fascinating and impactful problems the world has to solve: removing legacy carbon emissions in service of cooling the planet. We know that innovation requires creativity and courage and we give our people ownership to follow their curiosity to a solution. We work fast and collaboratively, learning from each other as we create answers to climate’s most pressing questions. Avnos is a place where you can see the impact of your work in the real world. At Avnos, we believe in the power of diversity and inclusion to drive innovation and success. Our mission-driven culture is fueled by individuals from various backgrounds, experiences, and perspectives coming together to make a meaningful impact.

Your unique talents and perspectives are not just welcomed; they are essential to our success. Apply today and be a part of a team that is dedicated to making a meaningful difference in the world.

Zenero helps consumer brands measure, verify, and communicate environmental impact with credibility. We deliver product-level Life Cycle Assessments (LCAs), power Digital Product Passports (DPPs), and provide compliance-ready carbon labels at scale. The standard for carbon labelling, built for sustainable brands and conscious consumers.

Prithu is a leading end-to-end carbon project developer, working with a goal of sequestering 20 million tonnes of CO2e by 2030. We help smallholder land stewards mitigate and adapt to climate change through the development and scaling of Nature Based Solutions (NBS). Thousands of smallholder farmers form the core of our operations, implementing projects in regenerative agriculture, biochar, and afforestation, reforestation, and revegetation (ARR) across the Indian subcontinent. Our model ensures that land stewards receive the majority of project benefits, aligning incentives locally while strengthening the long-term sustainability of our projects. We validate practice implementation, emissions, and removals through our state-of-the-art blockchain-based monitoring, reporting, and verification (MRV) system, powered by remote sensing, machine learning, and biogeochemical modelling, and calibrated using soil samples to accurately quantify and generate premium-quality carbon credits.
