Top 10: Sustainable Startups of 2023

We take a look at the top 10 startups demonstrating dedicated action to mitigate their climate impact, including Aurora Solar, AMP Robotics, and more

The path to sustainable operations is a tricky one, laden with unexpected pitfalls, significant sacrifices and lacking a unifying expectation of what ‘sustainable’ actually looks like in practice. Yet, getting a grip on emissions, waste and renewable resources among other elements – not to mention all the associated policy and process changes – is of vital importance in the coming years.

Enter the startup world. Often renowned for their ingenuity, scalability and passionate problem-solving, startups are perfectly poised to take on the mantle of sustainable practice and generate innovative solutions. Uninhibited by legacy tech and embedded processes, startups are free to assess sustainability in more efficient, effective ways.

Here, we take a look at the top 10 sustainable startups of 2023 to see which are prioritising the planet over personal gain and devising sustainable solutions.
