Top Sustainability Startups in 2027

unWOOD is a new category of material engineered to transform low-value plastic waste into a sustainable and durable wood alternative. It rescues plastic from landfills, saves mature trees from being cut down, and is fully recyclable at the end of its life. unWOOD outperforms traditional wood by being resistant to water, termites, weather, and heat. One metric ton of Plastic Waste Recycled makes 2MT of unWOOD (that’s 40 benches) and saves 3 fully matured trees.

If you're excited about the future of work, tech with purpose, and building a better planet — come join us. Let’s make doing good the new normal.

At Emidat, we are building the first climate-native product management system for building material manufacturers. Emidat aims to decarbonise building materials, making up 11% of global GHG emissions. We collect data from physical production processes, generate a digital product passport with verified environmental data and make it usable along the value chain. In short: One solution to assess, design, buy, sell and manage products - with environmental impact at the core. Embodied carbon is emitted on day zero and can never be reduced later, while global floor area is set to double by 2060. From January 2026, EU regulation (CPR) requires verified environmental data. 430,000 manufacturers will need it, and only about 2,500 have it today. That gap is our market.

Amber is a new way to buy power, designed for a world powered by renewable energy. We give customers direct access to the real-time wholesale electricity price as it varies every 30 mins. We then provide the technology to shift energy usage to the times when cheaper renewables are available in the grid and export to the grid at times when the price is highest. It’s a cheaper way to buy power and the fastest way for Australia to reach 100% renewable energy. We have thousands of customers who love what we are doing and a great product that will play a significant role in driving Australia towards a renewable future. We are backed by Australia’s leading VCs (including Square Peg Capital and Main Sequence Ventures), impact-focused investors and individuals, and most recently by Commonwealth Bank. We’re now at a critical moment in taking the business to real scale as we disrupt a huge market for the better. We’re committed to building a diverse and inclusive workplace and a great culture of people who love coming to work to build a better world. You’d be a part of a rapidly growing team of over 60 with expertise across energy, technology, marketing, and operations.

At WeDriveU, our vision is to improve corporate mobility.
