What is the Music Industry's role in addressing our climate emergency?

There's a conversation I've been wanting to start amongst musicians: from your point of view, what are ways you see that our industry can “green” itself? I’m interested in hearing about all aspects of the industry: concerts, venues of all sizes, touring, orchestras, orchestra pits, music education- both private and institutional, backstage catering, recording studios, album releases, luthiers, publishers, etc.

I’d love to hear ideas large and small, and even ideas that might seem like pipe dreams, or that appear to be way out of the box.

I’ll go first: string recycling. A partnership between D'Addario and TerraCycle accepts strings and string clippings of all materials and from all instruments for recycling. Strings from orchestral instruments, guitars, basses, harps, mandolins, ukuleles, etc,
