Carbon accounting & offsets (2024)

Two years ago, VCs were tripping over themselves to invest in carbon accounting startups — which make tools to help businesses measure their emissions. But things were significantly quieter in 2023, and funding levels in 2024 are flat.

Some segments are doing well — carbon offset marketplaces, where businesses can select credits, are popping up around Europe.

Startups are also developing carbon registries — which assess the legitimacy of credits and put a stamp of approval on them — as well as producing data that can be used by companies and asset managers to assess the quality of credits they intend to purchase.

We’re seeing more specialism: startups are increasingly focusing on specific sectors, promising tailored measurements for industries like food and fashion, financial services and real estate.

Another trend: carbon credit marketplaces are turning away from offsets that avoid carbon entering the atmosphere, and towards ‘removals’, which actively remove carbon from the atmosphere.
