Top Climate Tech startups to watch in 2024

Climate change is one of the biggest threats to the world as we know it. From more frequent and intense droughts, storms, heatwaves to rising sea levels, melting glaciers and the warming of the oceans, we must take action. And, fast. Climate technology is a critical tool for addressing (and reversing) decades worth of damage to the environment. In the last year, Climate Tech alone raised $8.4B in capital. So as the world moves faster and faster towards a greener future we’ve pulled together a list of the ten Climate Tech startups to watch over the next 12 months.

By providing governments, businesses and communities with accurate data, Airly helps them to understand and respond to the threat of air pollution. Put simply, Airly means reduced emissions and improved public health.
Why we’re excited:
In the UK, air pollution is the biggest risk to public health. In fact, it is estimated that by between 2017 and 2025 the total cost to the NHS and social care system of air pollutants will be £1.6 billion. Finding a solution to air pollution is essential but until then measuring the air pollution around us is key to helping individuals lead happy and healthy lives. We’re all for Airly’s efforts to make this information easy and accessible to all.

Why we’re excited:
The cement and steel industries are two of the two largest producers of carbon dioxide (CO2), creating up to 13% of worldwide man-made emissions (yikes). To mitigate this impact and ensure a more sustainable future we need to develop zero carbon materials. We love Carbon Re because it is a company on a mission to accelerate this process, decarbonizing foundational materials such as cement using AI.

Greyparrot AI

Greyparrot is a leading AI waste analytics platform for the circular economy, digitising the waste management industry to tackle the growing waste crisis head-on. Greyparrot’s mission is to increase transparency and automation in recycling by unlocking the financial value of waste and ultimately keep our planet clean.
Why we’re excited:
When it comes to how waste is managed, there has been no systematic accountability to date. Hence, stagnating recycling rates and devastating environmental impact. To put things in perspective most of our waste is not biodegradable and cannot be properly recycled meaning its filling our oceans and landfills! It’s clear something more needs to be done and we believe Greyparrot is the start-up to do just that.

Why we’re excited:
Plug sockets can account for as much as 40% of a building's energy use. Measurable.energy can help not only to prevent devices from drawing power but drive behavioural change meaning less small power waste. Afterall, small changes make a big difference.

Why we’re excited:
The impact of climate change will become more and more apparent with severe events like floods, heatwaves, wildfires, droughts, and storms becoming more frequent. The key is anticipating them. Climate X is focused on helping governments, financial institutions and businesses understand what that means for them - in unprecedented detail. This positive impact will not only be global but multi-generational.
