核心
碳——气候语境中的核心词,碳排放、碳足迹、碳中和的词根
释义
1
n.碳(化学元素,环境语境中指碳排放)
Scientists warn that unless countries dramatically reduce their carbon emissions within the next decade, the target of limiting global warming to 1.5°C will become unachievable.
科学家警告,除非各国在未来十年内大幅减少排放,否则将全球变暖限制在1.5°C的目标将变得无法实现。
2
n.(carbon dioxide)二氧化碳(CO₂,温室气体)
Burning fossil fuels releases large quantities of carbon dioxide into the atmosphere, trapping heat and contributing to the greenhouse effect.
燃烧化石燃料向大气层释放大量二氧化碳,困住热量并加剧温室效应。
语感
carbon emissions(碳排放);carbon footprint(碳足迹);carbon neutral(碳中和);carbon tax(碳税);low-carbon economy(低碳经济)
碳(化学元素)碳排放(carbon emissions 的简称)二氧化碳(carbon dioxide,CO₂)
陷阱
⚠️carbon footprint(个人/组织的碳足迹)vs. carbon emissions(可量化的总排放量)
Governments are increasingly introducing policies to reduce national carbon emissions, while individuals are encouraged to lower their own carbon footprints through lifestyle changes.
carbon footprint = carbon emissions(两者完全一样)
carbon emissions(碳排放量,通常指可量化的总排放数据:national/global carbon emissions = 国家/全球碳排放量);carbon footprint(碳足迹,指个人/组织全部活动产生的总碳影响,包含直接和间接排放);两个概念层次不同:emissions 更偏数据,footprint 更偏「影响痕迹」;此句两个词分别用于不同主体(政府 vs. 个人),正确
各国政府越来越多地出台政策以减少国家碳排放,同时鼓励个人通过改变生活方式来降低自身的碳足迹
⚠️carbon neutral(碳中和)vs. zero emissions(零排放)——程度不同
The airline announced plans to become completely zero emissions by 2050 by investing in sustainable aviation fuels and purchasing carbon offsets.
该航空公司宣布计划通过投资可持续航空燃料和购买碳抵消配额,到2050年实现完全零排放。(× zero emissions → ✓ carbon neutral,因为有碳抵消)
carbon neutral(碳中和)= 排放量通过抵消或吸收达到净零,但并非完全不排放;zero emissions(零排放)= 完全不产生排放,技术上目前对航空业几乎不可能;购买 carbon offsets 是「抵消」手段,说明仍有排放,因此应用 carbon neutral;× zero emissions → ✓ carbon neutral
The airline announced plans to become carbon neutral by 2050 by investing in sustainable aviation fuels and purchasing carbon offsets.
该航空公司宣布计划通过投资可持续航空燃料和购买碳抵消配额,到2050年实现碳中和
近义辨析
carbon vs emissions
carbon carbon(碳,在环境语境中常指碳排放:cut carbon = 削减碳排放;carbon emissions = 碳排放量) emissions emissions(排放物,排放量:greenhouse gas emissions = 温室气体排放;vehicle emissions = 车辆排放;比 carbon 范围更广,可指任何有害排放物,不限于碳)
The government has committed to reducing the country's carbon output by 45 per cent by 2030 compared with 1990 levels.
政府承诺到2030年将全国排放量比1990年水平降低45%。
Stricter regulations on vehicle emissions have led to a significant reduction in air pollution in major urban areas.
对车辆排放的更严格法规使主要城市地区的空气污染显著减少。

Businesses have a responsibility to measure and reduce their carbon footprint — not merely by purchasing offsets, but by fundamentally restructuring their operations to align with a low-carbon economy.
企业有责任测量并减少其足迹——不仅仅是通过购买碳抵消配额,而是从根本上重组运营以适应低碳经济。
常用搭配
carbon emissions碳排放(最高频搭配)
carbon footprint碳足迹(个人/组织的碳影响)
carbon neutral / carbon neutrality碳中和(净排放为零)
carbon tax碳税(对碳排放征税的政策工具)
low-carbon economy低碳经济
carbon offset / carbon capture碳抵消 / 碳捕获(减排机制)
词根
carbon = 碳(化学符号 C)→ 气候语境中 carbon = carbon emissions 的简称;carbon footprint = 「碳的脚印」= 活动留下的碳痕迹;carbon neutral = 「碳平衡」= 排放与吸收抵消

Q1义项辨析
下面四个句子中,carbon 的用法与其他三个最不同的是:
A
The factory has been ordered to reduce its carbon emissions by 30 per cent within three years.
B
Switching to renewable energy is one of the most effective ways to cut your carbon footprint.
C
Carbon is a chemical element found in all living organisms and forms the basis of organic chemistry.
D
The introduction of a carbon tax has been proposed as a way to incentivise businesses to adopt cleaner technologies.
C 中 carbon = 化学元素「碳」(科学基础语境);A、B、D 中 carbon = 环境/气候语境中的碳排放相关概念(carbon emissions / carbon footprint / carbon tax)
Q2对错判断
判断下面句子里的用法是否正确:
The shipping company aims to achieve carbon neutrality by 2040 by transitioning its fleet to hydrogen fuel and investing in reforestation projects.
achieve carbon neutrality(实现碳中和)固定搭配正确;carbon neutrality = 通过减排和碳汇实现净零排放;by transitioning...and investing 展示两种途径,语法正确
Q3近义选词
选择最恰当的词填空:
New regulations require all new vehicles to meet stricter standards for exhaust ___, as part of a broader effort to improve urban air quality.
Acarbon
Bemissions
✓ 新法规要求所有新车辆满足更严格的尾气排放标准,作为改善城市空气质量更广泛努力的一部分。
exhaust emissions(尾气排放)是固定搭配,指车辆排出的所有有害气体(不限于碳);emissions 比 carbon 范围更广;exhaust carbon 不是标准表达;此语境中需要通用排放术语,用 emissions
