Millions of sustainability jobs are available to people with the right skills. The problem: Many don't have them, especially women.

• Only 1 in 8 workers globally have the green skills companies are looking for, according to LinkedIn.
• The gap is most acute among women, highlighting an emerging "green ceiling." 
• Employers will have to rethink how they hire, LinkedIn told Business Insider.

The green transition is widely expected to create millions of new jobs around the world.
