What is RE-ZIP RE-ZIP is a circular packaging concept offering circular packaging to more or less all players in the ecommerce industry. By circulating and hence reusing rather than using single-use packaging (even recycled) we save CO2 even the first time a packaging is reused. It works likes this RE-ZIP delivers the packaging to webshops who offer the sustainable packing solution to their customers at check-out for a minor fee (paid back via reward voucher upon returning the packaging). Upon receipt of the goods the customer folds the RE-ZIP packaging to a return format and return it at a Drop Point. The packaging is returned to the RE-ZIP warehouse for cleaning and re-circulation to the webshops. The RE-ZIP packaging can be circulated up to 10 times, but more importantly the packaging will begin saving CO2 Within the first or second use – depending on the type. RE-ZIP has developed a state-of-the-art backend system supporting the above process and are currently operating in Denmark, UK and Poland. Hence working at RE-ZIP will offer you in-person colleagues in Denmark and remote colleagues in before mentioned countries and more to come. Working at RE-ZIP Working from the Danish RE-ZIP HQ you will find a bunch of nice new co-workers who appreciate to work from the office most days, because the energy we create together is important for us. That does not mean that you have to be here all day every day. You will have flexible working hours to accommodate your daily life. The atmosphere in the office is laid back and rather than working solo on projects and tasks we gather and combine our skills. Send us your application to come join us in our mission to change e-commerce packaging for good.

At North ESG, we’re building the AI-powered ESG accounting software for SMEs. 99% of all companies in Europe are small and medium-sized enterprises. They drive our economy - but when it comes to sustainability, they are underserved. ESG reporting is complex, time-consuming, and an administrative hassle. We believe the future of ESG should be about growth - not admin. Our mission is to free up time and strengthen the ESG profile of SMEs as a commercial advantage, so they can stay competitive, win more business, and meet rising demands from customers, regulators, and investors. Our platform automates the entire ESG reporting process using AI - from data collection to emissions calculations and EU-aligned reporting. It integrates with ERP systems and leverages both public and private data sources to generate tailored, commercially viable ESG reports. We’ve already gained strong market traction across industries in Denmark. And with ESG requirements increasingly cascading down from large corporates and financial institutions, we’re solving a growing pain for millions of SMEs across Europe.

Girls' education is an incredibly powerful climate solution due to its stong relationship with child marriage prevention and subsequent delayed motherhood; impacting population growth and lowering consumption-based emissions. 130 million girls in the world's poorest and most climate-vulnerable communities are effectively excluded from education due to poverty. Humanitarian organizations in low-income countries constantly struggle to fundraise and are never able to fully meet the needs of the most marginalized. SoGreen is a startup with a big heart and an even bigger ambition: A world where all girls realise their right to education and climate justice is placed at the heart of all climate action. In collaboration with leading scientists at renowned European research institutions in the field of demography and climate science,* SoGreen has developed a methodology to quantify the climate impact of girls' education in tonnes CO2-equivalent avoided. This allows for the generation of carbon credits (1 ton = 1 carbon credit) which can be sold on the international carbon market to channel climate finance to girls' education. In partnership with FAWEZA, a leading pan-African NGO focusing on girls' education, SoGreen's pilot project is being implemented in Zambia. Over the coming 5 years, the project will ensure a full secondary education for 180 marginalized girls. All carbon credits generated by the project have been sold ex ante to over 30 companies that have ambitious sustainability strategies, which allow for the use of carbon credits in addition to reducing their own emissions. SoGreen aims to be the provider of the worlds most popular carbon credits within the next 5 years; resulting in a powerful reduction in emissions and a massive increase in educational attainment - a basic human right. *International Institute for Applied Systems Analysis (IIASA) in Austria, Potsdam Institute for Climate Impact Research (PIK) in Germany, and The Wittgenstein Centre for Demography and Global Human Capital (WIC) in Austria.

Heated lifestyle products for bikes, to make green transport throughout the year the norm. Promoting winter cycling through engagement of committed, quality conscious cycling communities. We aim to bring a brand to life that makes people excited to cycle through winter because of the design and functionality it offers the cyclist. Our three product strategy takes the car seat heating concept and expands it into a visionary perspective of bicycles as a year-round transportation mode. Abrigo in Spanish means jacket - and the latin origin word, connotes shelter. We want to make cycles a a form of shelter so that we are able to bridge the transportation gap whereby summertime cycling far outweighs wintertime cycling. We are starting with heated seatwear, and are going to expand into handles and pedals, in due course.

Many people are talking about the smart grid and how we can reach 100% sustainable energy, and avoid global warming getting out of hand, by intelligently balancing the consumption so it fits with the electricity production. At True Energy we're already doing it! True Energy offers a smart charging app to our end users so they can register their car or charger and have it start or stop charging based on the hour of day and the electricity price, so the user optimizes their charging to be cheapest. The service is free of charge for the end user because they participate in our flexibility pool where the power companies can buy offsetting of the consumption if the grid is overloaded or production is expensive. We use Google Workspace, GitLab as code repo, Jira for our agile project management, and Slack for chat. We have a policy of 100% line coverage for unit tests, and want to support continuous delivery. We focus on collaboration and an open, inclusive work environment. Our team is multinational, and the working language is English, so full proficiency is required.. We have team members in several time zones.

We develop, innovate, produce and deliver scalable waste-based building elements and interior products for the professional built environment. The construction industry account for 40% of all waste generated and is the #1 consumer of raw materials globally. The embedded carbon in building materials account for 11% of global carbon emission. At the same time, global floor area is expected to double by 2060. Sustainable building materials will be key to reducing footprint from the construction industry. We need to change the way we build and focus on materials produced from non-virgin materials. We make it possible to accelerate the necessary change towards a reduced use of virgin raw materials in our buildings by developing new earth and climate friendly products and solutions based on waste, biproducts, unused resources, and discarded production. We make it easy for the ones who design and build to choose a waste-based product, for the benefit of the environment, the user and the investor. Our approach is scalable. We are experts in creating valuable upcycledproducts from scalable sources of waste.We see opportunities, when others see waste. Our know-how drives innovation and product development and shape the products of tomorrow with the waste of today. Together with our trusted production partners, we offer our products at scale to the professional customer with warranties, guaranteed delivery, certifications and documentations.
