Activist Greta Thunberg spoke to BBC Scotland ahead of the COP26 climate change summit, which is due to take place in Glasgow in November.
In a wide-ranging interview, Ms Thunberg said she was “not 100% sure” she would attend the talks and that her decision would depend on whether the event was “safe and democratic”.
She added that if she decided to come to Glasgow, her plan would be to travel by train from Stockholm.

“It has to be all about climate justice and we can’t achieve climate justice if everyone doesn’t contribute on the same terms,” she explained.
