This video
Has been blocked worldwide, again a 2 min excerpt, about climate solutions. Here about the city of Masdar.
It is unclear why the BBC is blocking videos which explain basic science or solution to dangerous climate change. For now i can not recommend to use any BBC footage, because it will eventually be blocked, even if you give credit and use short excerpts to promote science and education to solve climate change under fair use guidelines.
