Dubai is hosting the UN COP28 summit on climate change, which aims to encourage countries to speed up their energy transitions. The fact that the event is taking place in an oil-rich emirate is the last straw for many activists, who are boycotting the event. Dubai, home to artificial islands and ski slopes in the desert, is nonetheless trying to boost its green credentials and is counting on startups to do so.

Several companies at the Paris Air Show are presenting advanced prototypes of air taxis that could offer an alternative means of inner city transport. One of them, German group Volocopter, is aiming to get its aircraft up and running for the 2024 Paris Olympics. Also in the show, we look ahead to the Summit for a New Global Financing Pact that's taking place in Paris later this week. World leaders will be convening to discuss changes to the global financial system in order to better respond to the climate emergency.
