What is net zero? We release 55 gigatons of greenhouse gases into the air every year. To stop global warming, we have to get our greenhouse gas emissions down to zero.
什么是净零? 我们每年向空气中 排放 550 亿吨温室气体。 为了阻止全球变暖, 我们必须将温室气体排放量降至零。
But for every country to immediately shut down all greenhouse gas-releasing activities would be an enormous challenge, especially since some countries have built up an economic head start with no restrictions. So instead, we can use an approach called net zero.
但是立即停止 所有温室气体排放活动 对每个国家来说 都将是一个巨大的挑战, 尤其是因为部分国家 已经建立了不受限制的经济先机。 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, we also take one out, making our net emissions zero. Net zero requires us to make big changes today, use less more efficiently, and even bigger technological changes for the future, like replacing all greenhouse gas-emitting activities with clean ones. We'll also have to capture greenhouse gases from the air and store them permanently. And yet, net zero is our best chance for a sustainable future.
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, 使我们的净排放量为零。 净零要求我们今天做出巨大的改变, 更有效地使用更少的资源, 并为未来做出更大的技术改变, 比如用清洁的活动取代 所有温室气体排放活动。 我们还必须从空气中捕捉温室气体, 并将其永久储存起来。 然而,净零排放是我们实现 可持续未来的最佳机会。
