In 1992, more than 150 countries signed the United Nations Framework Convention on Climate Change (UNFCCC). The environmental treaty was designed to support a global response to climate change. Every year, delegations from countries signed to the convention gather for the Conference of the Parties, more commonly known as COP. The first COP was held in Berlin in 1995. More than 25 years later, the Scottish city of Glasgow will host COP26 at the beginning of November this year. Watch the video above to learn what happens at COP and the role it plays in the fight against climate change. ----- Subscribe to us on YouTube: http://cnb.cx/2wuoARM Subscribe to CNBC International TV on YouTube: https://cnb.cx/2NGytpz Like our Facebook page: https://www.facebook.com/cnbcinternational Follow us on Instagram: https://www.instagram.com/cnbcinternational/ Follow us on Twitter: https://twitter.com/CNBCi
