Our seas and oceans are an impressive force of nature, but they also hold the potential for innovative new environmental solutions.

Whale faeces is the starting point of many food chains in the ocean. Researchers are now trying to use excrement from the lab as fertiliser to boost the CO2 storage of the oceans.

Heavy industries like cement and steel are dirty business. But can new carbon capture technologies help them to become more circular?

This year, the non-profit organisation Atmosfair built the world's first industrial production facility for synthetic kerosene, thus providing CO2-neutral fuel for commercial aviation.

As carbon dioxide levels hit record highs, scientists and entrepreneurs around the world are devising new ways to “scrub” the atmosphere of CO2. For its part, California-based startup Holy Grail is developing cost-effective, simple carbon capture devices that can be deployed by small businesses, and maybe – one day – even individual consumers.

Poorly understood peatlands have long been carelessly exploited, releasing their stored up carbon. With the help of satellites and advanced software, researchers now hope to accurately measure their vital signs.
