The world faces the harsh realities of climate change, with rising sea levels, severe droughts, and catastrophic wildfires becoming more frequent and intense. The need for solutions to mitigate the devastating impacts of climate change has never been more pressing. Thankfully, a new generation of climate tech startups is rising to the challenge. These companies are leveraging the latest scientific and technological advancements to create innovative solutions that reduce greenhouse gas emissions, protect the environment, and pave the way toward a more sustainable future for all.

As highlighted by the latest United Nations IPCC climate report, the situation is dire, and urgent action is required from all sectors of society. These climate tech startups are at the forefront of this effort, working tirelessly to develop cutting-edge technologies to help mitigate the worst effects of climate change. Here are some of the most promising climate tech startups making a real difference.


ReSeed created a program that enables farmers to create carbon credits for their contributions to environmental conservancy by sequestering carbon and reducing carbon emissions through sustainable farming practices. The program begins with the farmer entering data through ReSeed’s mobile app, providing information about their crops, farming practices, and other relevant details. ReSeed then verifies this data using an AI engine that collects information from trusted sources. Based on this data, ReSeed generates carbon credits for each farm, representing the amount of carbon sequestered by the farmer. The credits are then paid directly to the farmers, incentivizing them to maintain and grow their carbon stocks. This creates a cycle of environmental stewardship, which benefits not only the farmers but also consumers, companies, and investors who support sustainable farming practices.

Impossible Metals

Impossible Metals is a robotics company that has successfully developed a new technology to collect critical metals from untouched regions five miles under the sea. The metals collected are important in developing batteries for electric vehicles (EVs). With the rising demand for EVs, mining efforts for these critical metals like nickel, cobalt, copper, and lithium, among others, have had detrimental impacts due to land-based mining and seabed dredging. Impossible Metals provides a sustainable solution by collecting these metals safely and harmlessly in the seabed using their robotic vehicle, Eureka 1, which hovers above the seabed without touching it. In addition, the vehicle is designed to identify which rock nodules have life growing on them, such as sea coral, sea sponge, or any indication of life, which are excluded from collection efforts and not disturbed. This new technology will combat the mining industry and provide more sustainable solutions, positively impacting global supply chains.


OceanShot, led by climate scientist Dr. Deborah Brosnan, is a coral restoration project that aims to protect coastal communities from the effects of climate change. By building a huge coral module and growing hundreds of baby corals that can be planted into reefs, OceanShot can revitalize marine biodiversity and bolster local economies that depend on the ocean. The project launched off the coast of Antigua and Barbuda in collaboration with the nation’s government and philanthropist JP DeJoria, has already seen promising results. In just four months since its deployment, fish that had left dead coral have returned, providing hope for the recovery of the ecosystem. With scalable solutions, OceanShot can protect coastal communities worldwide from the ravages of the climate crisis.

CarbonCure Technologies

CarbonCure Technologies is a company shaking things up in the concrete industry with a groundbreaking solution to reduce carbon emissions. They inject carbon dioxide (CO2) into wet concrete during mixing using innovative technology. But here’s the kicker: the CO2 makes the concrete stronger and reduces its carbon footprint. This means that their solution benefits the environment and leads to stronger and more durable concrete. With over 300 concrete plants worldwide already using their technology, CarbonCure has avoided over 200,000 metric tons of CO2 emissions, which is no small feat.


Terramera is a company that is developing sustainable pest control solutions to protect crops while reducing the use of harmful chemicals. The company’s technology is based on a patented platform called Actigate, which delivers plant-based pest control products more efficiently than traditional methods. Terramera’s mission is to create a world where healthy food is grown without compromising the health of the environment, farmers, or consumers.

As the IPCC report highlights, climate change is a global crisis that requires urgent action. Fortunately, these innovative startups are stepping up to the challenge and creating technologies making a difference. These companies represent just a tiny sample of the many startups working towards a more sustainable future. As the world comes together to tackle this issue, these startups will play a critical role in helping to mitigate the effects of climate change and pave the way toward a more sustainable future for all.
