碳排放税将为每单位二氧化碳设置一个具体的成本，并因此为碳确定一个清晰的成本。
A carbon tax would set a specific cost per unit of carbon dioxide, thus establishing a clear cost for carbon.
要是能够说服人们停止伐木，到2020年这些幸免的树木所吸收的二氧化碳会占到碳排放下降数量的30%。
If people can be persuaded to stop chopping down trees, avoided deforestation might account for 30% of the reductions in carbon emissions by 2020.
甲烷是这些气体的最重要部分，然后才是黑碳和一氧化氮。
Methane is the most important of these gases, followed by black carbon and nitrous oxide.
像二氧化碳一样，黑碳吸收阳光和红外线辐射，将热量滞留在大气中-包括最接近地球表面的边界层。
Like carbon dioxide, black carbon absorbs sunlight and infrared radiation, trapping heat in the atmosphere — including the boundary layer closest to Earth's surface.
尽管生物物质当它燃烧时，像汽油一样释放碳，但是当植物生长时，它们吸收大气中的二氧化碳，减少了总的碳迹。
Even though biomass releases carbon when it is burned, just like oil, when new plants are growing they absorb carbon dioxide from the atmosphere, reducing the overall carbon footprint.
干木材重量的大约一半是由碳组成的，如果树腐化了，或被燃烧了，大部分碳都会以二氧化碳的形式释放出来。
