Toco

Toco is on a mission to revolutionize the economic system by recognising our most valuable asset - our Home Planet. Through an innovative approach, Toco introduces a new digital currency backed by real-world climate projects that reduce and remove CO2 from the atmosphere and contribute to saving our Home Planet. With an easy-to-use payment app, Toco makes every transaction - from buying a plant-based burger to renting a city bike - a step forward towards solving climate change. OUR WHY: We are on a mission to solve climate change. We must protect our common resources that are vital to life on earth. We are uniting communities to make climate action simple. HOW: We have tested this concept in Stellenbosch, a small South African town, with 67% business adoption and 45% MoM Community growth. Individuals could live in a currency that values the environment instead of its destruction. We are now expanding in Zurich and Denmark. Toco is a new global currency backed by CO2 (Supported by https://www.thecarbonreserve.org/) Every toco represents one tonne of CO2 credibly mitigated from the atmosphere. We turn economic activity into climate action. CURRENTLY: This summer, Toco is launching in Copenhagen, offering a unique opportunity to join a climate-forward movement of talented individuals called the Custodians of the Common. Custodians are passionate about using their time and talents to protect the environment and solve the greatest challenge of our time - climate change. Custodians come together to create change NOW, driven by the realisation that time is running out for the planet’s finite resources and there is NO PLAN(ET) B! As a Custodian, you will be at the forefront of introducing Toco to Copenhagen, spreading the word, and onboarding businesses and individuals to join the movement and start using a currency that directly contributes to sustainable projects that remove or reduce carbon dioxide from the atmosphere, to combat climate change. Beyond the climate impact that each Custodian creates, Custodians volunteer their time and are financially rewarded based on the climate impact they create.

Responsibly

Responsibly is a sustainability tech start-up with vision of making every purchase in the world responsible 🌍 There's no bigger problem out there than the climate, and procurement represents a big part of the solution - when purchase decisions are made on the background of responsible data like CO2 footprint, suppliers have a huge incentive to change. However, procurement is becoming overloaded with complexity. Different frameworks, different data sources, different coverage, making it difficult to make purchase decisions to improve your responsibility profile and scope 3 emissions. At Responsibly, we're trying to solve this issue by using leading technologies and data science, to build a supplier data platform that makes it easier to source responsibly. We're founded by two serial entrepreneurs with previous successes like Dixa and Ofload, and have received pre-seed funding from some of Europe's top VCs and angels. We're now building a top-tier team to tackle this big thing called climate, and have fun while we're doing it 🤘

ENZIDIA

Enabling the bioindustrial revolution with the fastest enzymes. Many of the hardest climate and environmental problems can be solved through synthetic biology. But biosolutions are held back by the enzyme efficiency bottleneck. The ENZIDIA Enzyme Engineering Platform will address this with 10^4 to 10^7 times higher efficiency than current technologies.

GLYON

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.

FuelVision

FuelVision is a climate tech startup building a more sustainable aviation industry. We bridge the gap between flight data and real operational decision-making. We are building an intelligence platform that processes Flight Data Monitoring at scale. Using machine learning and behavioural science, we turn raw data into personalised, actionable insights for airlines and pilots. Our solutions give airlines fleet-wide optimisation and risk awareness, and provide pilots with an engaging mobile app where flying becomes measurable, improvable and meaningful. Think Strava for pilots: track your impact, understand how your technique influences each flight and take pride in flying at your best. We are forming a small team of curious, ambitious builders who want to work on something real and consequential. You will help shape a product with tangible operational impact, move fast and work closely with pilots and aviation experts to make data genuinely useful. If you want to put your skills into something that matters in the real world, FuelVision could be the place for you.

ClimEdU

The world is changing and we have to move towards more sustainability. ClimEdU works for this change. We help businesses to optimize their: - Production - Value chain - Internal recruitment - Leadership - Green profile How do we do it? We research and calculate their carbon footprint for the above and suggest ways to improve this. That way companies can become more sustainable as well as more preferred by investors and clients who choose green profiles more and more. The EU has voted for a directive that is called CSRD, which in danish is equivalent to ESG (Environment, Social and Governance) But we don't just do that. We also help architects and others in the construction industry with LCA's (Life Cycle Analysis) And we offer a marketing strategy and a plan to fulfill the goals in the ESG plan. Finally, we're making a platform, that is going to revolutionize the industry. We want to automate as much of the processes as possible. So we are always looking for the best candidates to help us on our journey. Almost all companies will need this service sooner or later (Check out the plan from the CSRD directive) so we need to make ourselves as visible as possible and if you can help us with that, let's have a talk.
