The pairing will see national Geographic commit £7m worth of expertise, grants and media reach in support of Sky Ocean ventures, a £25m commitment by Sky to develop new solutions to the problem.
This will give priority to measures geared toward reducing the flow of plastics into waterways at source by encouraging greater recycling and waste management. It also hopes encourage technological innovation to reduce manufacturing inefficiencies and drive material innovations.
Sky’s Group chief executive Jeremy Darroch commented: "I’m excited that we share the same vision and understand the pressing need to take action and find meaningful solutions to the plastics problem.
"Together, we will create real impact, and I look forward to bringing other financial and non-financial partners on board.”
Gary Knell, chief executive of National Geographic Partners, added: “Sky Ocean Ventures is a bold new project that will support breakthrough thinking and invest in new ideas aimed at the impact plastic is having on our oceans and marine life."
Awareness of the issue is being raised by marine organisation Sea Shepherd, which together with FF New York has highlighted the plight of sea creatures snared by plastics.
