Dialogue: 0,0:00:10.00,0:00:13.86,Default,,0000,0000,0000,,we have to get our greenhouse\Ngas emissions down to zero.
Dialogue: 0,0:00:13.88,0:00:16.74,Default,,0000,0000,0000,,But for every country\Nto immediately shut down

Dialogue: 0,0:00:18.99,0:00:21.05,Default,,0000,0000,0000,,would be an enormous challenge,
Dialogue: 0,0:00:21.08,0:00:22.63,Default,,0000,0000,0000,,especially since some countries

Dialogue: 0,0:00:35.61,0:00:37.48,Default,,0000,0000,0000,,we also take one out,
Dialogue: 0,0:00:37.50,0:00:40.18,Default,,0000,0000,0000,,making our net emissions zero.
Dialogue: 0,0:00:40.21,0:00:43.27,Default,,0000,0000,0000,,Net zero requires us\Nto make big changes today,

Dialogue: 0,0:00:57.67,0:01:02.55,Default,,0000,0000,0000,,And yet, net zero is our best chance\Nfor a sustainable future.
