As urbanisation accelerates and infrastructure decays, researchers are working out how cities can heal themselves. As the FT’s Nikou Asgari explains, they are carrying out tests on materials that repair themselves and an army of maintenance robots that can work around the clock. Small robotic worms will find and fix leaks in buried water pipes and drones will detect and patch up potholes in the middle of night.
Can whales help cool the temperature of our planet? A whale’s body can store up to 33 tonnes of harmful carbon dioxide. When they die and sink to the ocean floor, all that carbon is stored there for centuries...
Oceans are the source of at least 50 per cent of all oxygen produced on Earth. Yet industrial fishing, offshore oil exploration and using the ocean as the world’s dumping ground for plastics and harmful chemicals have placed this fragile ecosystem...
The long haul to zero emissions aviation. Intriguing technologies are emerging which could lead to zero emissions aviation. Bio and synthetic fuels are viable, but still expensive and not perfectly clean.
The world is choking on plastic waste. Less than nine per cent of it is recycled, but an emerging industry promises to change all that. The FT’s Charlotte Middlehurst discovers how chemical recycling...
Renewable energy sources such as wind and solar power are now becoming viable alternatives to fossil fuels. But for electricity grids, constantly matching supply with demand becomes much harder when you strip out coal and gas-fired plants that provide...
If renewable energy is going to provide a steady source of energy to power grids, we need to find ways of storing it. Lithium-ion batteries are currently the dominant technology, but new rivals are emerging.
Patagonia and Stella Mccartney have been singing the tune of ethical fashion for a few decades, but it wasn't until the past few years that some of the most exciting innovations in environmentally conscious fashion have been launched.
Could the second-hand clothes market help support a circular economy? With over 80 billion garments being produced every year and garments only being worn 7 times before being thrown away, the fashion industry has a massive negative environmental impact.
Amidst the growing appetite among companies and investors for disclosure of environmental, social and governance data, the London Metal Exchange plans to launch a platform which trades ‘low-carbon’ aluminium.
Aluminium is lightweight, durable, and 100% recyclable. It’s also a key input for numerous industries. But today, the aluminium sector contributes about one per cent of global greenhouse gas emissions.
Start up, Dendra Systems, aims to restore ecosystems and biodiversity using AI and drones. With the ability to analyse an entire ecosystem down to a blade of grass, Dendra Systems hopes to restore and reforest areas around the world that have been damaged
