THE UPCYCL

THE UPCYCL connects your industrial waste streams with your neighbors supply chain. We make it possible to reduce our amounts of industrial waste, by turning waste material streams into business opportunities. Our material database displays leftover materials from production, giving developers easy access to reusable materials, also called "New Waste". Hereby, achieving a significantly lower CO₂ footprint than with virgin materials. When circulating New Waste materials with the THE UPCYCL, we also offer to monitor CO₂ savings. We work to accelerate the use of circular materials, worldwide. Because Waste is Everyone's Business!

Copenhagen Atomics A/S

We are changing the world! Copenhagen Atomics is building the next generation nuclear reactors for the world based on molten salt technology. This provides a cheap and clean energy source that aims to change the energy system in general. A thorium based molten salt reactor is small, efficient, safe and is burning the nuclear waste from current nuclear plants.

GoBoat

Climaider

Climaider is a rapidly growing startup, enabling Small and Medium sized Enterprises to measure and report their ESG and to take real climate action. ESG reporting is becoming a necessity if you want to stay competitive, retain your employees, get funding or financing and win customers and jobs. But SMEs have been left behind in a reporting environment that has been shaped first and foremost to accomodate very Large enterprises - leaving SMEs with an extremely complicated and tedious reporting job that often falls on employees or owners with a 1000 other responsibilities too. We help and guide SMEs, automate +95% of the work and instill in them the confidence that they can do this and that they have done it the right way. Our goal is to remove the headache of reporting, leaving room to focus on what is actually important: Reducing the carbon footprint of your company. We're set on becoming THE solution for SMEs all over Europe, making reporting easy, comparable and actionable. Join us!

KhaosGuard

KhaosGuard is making greenhouse gas emissions visible. KhaosGuard is developing a new generation of laser and optical technology that can measure, map and quantify greenhouse gas emissions across large areas in real time. By combining advanced mid-infrared laser spectroscopy, optical sensor networks and wind-field data, we can turn complex emission plumes into accurate, quantitative measurements of where emissions come from and how much is being released. Our technology brings together advanced spectroscopy and atmospheric modelling in a robust field system — creating a level of spatial and real-time emissions intelligence that has not previously been available. Starting with wastewater treatment Our first focus is wastewater treatment plants, where we are helping operators detect, localise and quantify nitrous oxide (N₂O) emissions — commonly known as laughing gas and a highly potent greenhouse gas. By making these emissions visible, we give wastewater operators the intelligence they need to understand what is happening across their plants, identify emission hotspots and optimise their processes for greater efficiency and lower emissions. Ultimately, our goal is simple: you cannot optimise what you cannot measure.

Elby

Personal transportation is one of the greatest sources to Co2-emmission and air pollution. The change from a fossil fuel car to an EV is the lowest hanging fruits to decrease this emmission. Before you make this shift, you want to make sure that you can charge your car, which can be challenging if you live in a city, where you depend on a public roll out of EV charging infrastructure, which often lacks behind. This is what we want to change with Elby. Elby's solution enables an ubiquitous roll out on market conditions and at a marginal cost of the known solutions.

Envira

Envira is a Copenhagen-based climate-tech company that turns satellite and environmental data into decision-ready intelligence for finance, government, and agriculture. By combining Earth Observation, advanced analytics and deep regulatory expertise, we translate complex, forward-looking signals into clear, auditable answers — not just raw layers — so organisations can quantify risk, build resilience and act with confidence.

PhaseTree

PhaseTree is a pioneering deep-tech startup from the Technical University of Denmark (DTU), founded in 2021 with a mission to revolutionize materials discovery for the energy industry. Traditional development of new materials—such as advanced battery technologies and catalysts for hydrogen production—can take decades, creating a significant bottleneck in the global effort to combat climate change. PhaseTree aims to change that. By combining cutting-edge computer simulations, lab automation, and artificial intelligence, PhaseTree dramatically accelerates the research and development process, unlocking breakthrough materials at unprecedented speeds. Our innovative approach not only helps build a more sustainable future but also creates unique business opportunities in the rapidly evolving clean energy sector. With a team of world-class scientists and engineers, PhaseTree stands at the forefront of AI-driven materials discovery, ensuring that the next generation of energy technologies arrives faster, more efficiently, and at lower costs.

Nordic Smart Grid Solutions (NSGS)

At Nordic Smart Grid Solutions (NSGS), we believe the green transition requires more than just ambition, it requires action. We exist to solve the overlooked technical challenges that keep renewable assets from going online. Our work is defined by bridging the gap between the digital world of cloud architects and the physical reality of high-voltage renewable infrastructure. Whether we are on-site commissioning Battery Energy Storage Systems or deploying our AI-driven SiteKick tools, our goal is to resolve the technical bottlenecks that slow down the green transition. By combining deep engineering expertise with scalable digital solutions, we ensure that connections are safe, assets are efficient, and the world moves closer to clean, reliable, and affordable energy, one commissioned site at a time.

Incremental Maritime A/S

Incremental Maritime is developing a digital compliance solution that helps shipowners and operators navigate complex decarbonization regulations; transforming compliance into lower emissions and higher margins. Our deep regulatory expertise, data-driven models, and hands-on client support are what set us apart. Global shipping faces an accelerating tide of climate regulation, from the IMO’s GHG Fuel Intensity targets to FuelEU Maritime and EU ETS. These rules impact everything: fuel costs, asset values, and day-to-day operations. Yet most market players lack the tools and insights to respond; let alone turn compliance into an advantage. This leaves shipowners and operators asking: - What decarbonization investments make financial sense? - How do I reduce risk and avoid penalties? - Can I stay compliant across multiple regimes without extra complexity? - Without smart tools, these questions are hard to answer - and costly to get wrong. Our solution has two core parts: Advisory with immediate impact: We help clients assess regulatory costs, model emissions, evaluate investment cases, and support decision-making from planning to operations. A digital compliance agent (in development): Built on real client work, this tool will combine - Real-time emissions tracking - Cross-jurisdictional compliance logic - Commercial impact analysis - Support from pre-fixture to post-voyage We’re building the go-to compliance engine for modern shipping: one that simplifies decisions, protects margins, and scales with regulation. We launched Incremental Maritime because we saw a blind spot: climate regulation was outpacing the industry’s ability to respond and the result was confusion, cost, and missed opportunity. With experience spanning maritime operations and regulatory systems, we knew we could help. We believe that smarter compliance is not a burden, it’s a pathway to performance. We're here to equip shipping with the tools to decarbonize profitably, one fixture, one voyage, one regulation at a time.
