The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.

这个额外的电子填充了传导带的较低能级，有效的导致了被激发的电子溢入较高，释放光子的能级。

Let's grasp the opportunities to link agriculture with the transition to lower carbon-emitting, climate resilient growth.

让我们抓住机会把农业与向低碳排放、气候弹性增长联系起来。

The least-cost option to lower the risk is to start now and steadily transform the global energy system over the coming decades to low or zero greenhouse gas-emitting technologies.

降低风险的最小开销方案就是现在启动政策并且在未来数十年内逐步将现在全球能量系统转变为低温室气体排放或零排放的技术。

The technique will be successful only if the cost of hiding a tonne of carbon underground falls lower than the cost of emitting a tonne into the air.

Across all sectors of the economy, decreasing consumption of carbon-emitting fossil fuels resulted in both a lower carbon intensity and lower absolute emissions.
