0:00:01.190,0:00:03.290
What is net zero?

0:00:03.290,0:00:06.720
We release 55 gigatons of greenhouse gases

0:00:06.720,0:00:08.490
into the air every year.

0:00:08.490,0:00:10.000
To stop global warming,

0:00:10.000,0:00:13.880
we have to get our greenhouse[br]gas emissions down to zero.

0:00:13.880,0:00:16.760
But for every country[br]to immediately shut down

0:00:16.760,0:00:18.990
all greenhouse gas-releasing activities

0:00:18.990,0:00:21.090
would be an enormous challenge,

0:00:21.090,0:00:23.290
especially since some[br]countries have built up

0:00:23.290,0:00:26.310
an economic headstart[br]with no restrictions.

0:00:26.310,0:00:30.610
So, instead, we can use an[br]approach called net zero.

0:00:30.610,0:00:34.140
Net zero means that for every[br]molecule of greenhouse gas

0:00:34.140,0:00:36.713
we put into the air, we also take one out,

0:00:37.556,0:00:40.220
making our net emissions zero.

0:00:40.220,0:00:43.290
Net zero requires us to[br]make big changes today,

0:00:43.290,0:00:45.230
use less more efficiently,

0:00:45.230,0:00:48.290
and even bigger technological[br]changes for the future,

0:00:48.290,0:00:51.400
like replacing all greenhouse[br]gas-emitting activities

0:00:51.400,0:00:52.420
with clean ones.

0:00:52.420,0:00:55.160
We'll also have to capture[br]greenhouse gases from the air

0:00:55.160,0:00:56.713
and store them permanently.

0:00:57.700,0:01:00.140
And yet, net zero is our best chance

0:01:00.140,0:01:01.643
for a sustainable future.
