When we measure methane in carbon dioxide equivalent, methane emissions only account for 10% of greenhouse gas emissions in the US.

当我们用二氧化碳当量来衡量甲烷时，甲烷排放量只占美国温室气体排放量的 10%。

And that represents about two billion tons of carbon dioxide equivalent per year, or more than four percent of our annual global greenhouse gas emissions.

这相当于每年 20 亿吨的二氧化碳量，或超过每年全球温室气体排放的 4%。

One acre of trees annually consumes the same amount of carbon dioxide equivalent to driving an average car for 26,000 miles (41,842 km).

一英亩的树木每年消耗的二氧化碳量相当于一辆普通汽车行驶 26,000 英里（41,842 公里）。
