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.

With over 300,000 visitors and thousands of deals expected to be made, exhibitors from the aeronautic and air defence industries have gathered outside Paris for the "Le Bourget" air show. We also take a look at Switzerland's decision to become carbon neutral by 2050 and raise corporate taxes to 15 percent.
