What is net zero?

什么是净零？

We release 55 gigatons of greenhouse gases into the air every year.

我们每年向空气中 排放 550 亿吨温室气体。

To stop global warming,

为了阻止全球变暖，

we have to get our greenhouse gas emissions down to zero.

我们必须将温室气体排放量降至零。

But for every country to immediately shut down

但是立即停止 所有温室气体排放活动

all greenhouse gas-releasing activities

对每个国家来说

would be an enormous challenge,

都将是一个巨大的挑战，

especially since some countries

尤其是因为部分国家

have built up an economic head start with no restrictions.

已经建立了不受限制的经济先机。

So instead, we can use an approach called net zero.

因此，相反，我们可以 使用一种叫净零的方法。

Net zero means that for every molecule of greenhouse gas we put into the air,

净零排放意味着我们每把一个

温室气体分子排入空气中， 我们也会排出一分子，

we also take one out,

making our net emissions zero.

使我们的净排放量为零。

Net zero requires us to make big changes today,

净零要求我们今天做出巨大的改变，

use less more efficiently,

更有效地使用更少的资源，

and even bigger technological changes for the future,

并为未来做出更大的技术改变，

like replacing all greenhouse gas-emitting activities with clean ones.

比如用清洁的活动取代

所有温室气体排放活动。

We'll also have to capture greenhouse gases from the air

我们还必须从空气中捕捉温室气体，

and store them permanently.

并将其永久储存起来。

And yet, net zero is our best chance for a sustainable future.

然而，净零排放是我们实现

可持续未来的最佳机会。
