carbon budget

The remaining global carbon budget to limit warming to 1.5°C is shrinking rapidly given current emission rates.鉴于当前的排放速度，将变暖限制在1.5°C所需的剩余全球碳预算正在迅速缩减。

National carbon budgets allocate each country a share of the global limit consistent with agreed temperature targets.国家碳预算为每个国家分配了符合商定温度目标的全球排放上限份额。
