🏢 ClimateHack Vol. 51: Decarbonizing cities

PLUS: Czech startup Woltair secures €20.5 million for their heat pumps.

Hey There,

Fun fact: While only covering 2% of the Earth’s surface, cities are one of biggest contributors to the climate crisis (≈70% of GHG emissions).

Okay, not so fun - but decarbonising cities is absolutely critical to a net zero future, and will require significant investments in low-carbon energy and transport systems, programs to reduce urban sprawl, and nature-based solutions for urban cooling and disaster risk management.

Step in Sweden’s CliamteView, which helps cities analyze, plan and finance projects that will reduce their climate footprint and fossil emissions.

Their solution is already used by over 30 cities across the world including metropoles like Madrid, Dortmund, Cincinnati and Nottingham - and this week the company announced their €14M in funding led by 2050.

ClimateView are doing what I like to call the boring, but essential work. No one really likes doing planing, budgeting, reporting - but it is essential in order to mobilize capital towards climate action.

Any other examples of the boring but essential work in Climate? I’m making a list.

In today's edition:

🍗 USDA has approved the label “cell-cultivated chicken”.
🌡 Czech startup Woltair secures €20.5 million for heat pumps.
👜 Biomaterials startup Uncaged Innovations raised $2M from Land Rover.

🍗 The USDA has approved the label “cell-cultivated chicken” for the chicken produced by Eat Just and Upside Foods, when the products are eventually approved for sale. The approval signifies that the department feels these companies “have demonstrated full compliance with pre-market labelling requirements”, and brings them a step closer to commercialisation.

🧫 UK-based industrial biotechnology CDMO Extracellular announced the availability of low-cost and license-free cell banks for early-stage cultivated meat researchers and startups. Its animal primary cells suitable for cultivated meat research and development are up to 90% cheaper than other cell line providers and free from licensing restrictions.

🧀 Californian food tech Climax Foods debuted what it says is the world’s first plant-based casein, which it claims mimics the functionality, flavour, texture, melt, and stretch of animal dairy casein.

🍦 Singapore restaurant Fico unveiled the world’s first gelato made from air, developed using Finnish startup Solar Foods’ incredibly versatile Solein protein.

💡 Good Read: Steve Molino, Principal at Clear Current Capital, tells what it’s like attending a cultivated meat tasting and explains why, without trust, it’s game over for sustainable foods.
