欧盟碳市场为什么要在2019年推出「市场稳定储备」机制?它针对哪种结构性缺陷,又如何发挥作用?
Why did the EU carbon market launch the Market Stability Reserve in 2019, which structural defect does it address, and how does it operate?
为治理配额长期过剩导致的碳价失灵。危机后排放需求下滑而分配规则未变,流通过剩配额一度超过20亿吨,碳价低迷到失去减排投资信号。MSR自2019年按规则自动运行:流通配额高于阈值时,每年将其中的24%(2024年起降为10%)转入储备库冻结,跌破下限再逐步回流拍卖;这相当于给供给装上自动稳定器,不重开立法谈判即可恢复稀缺性与价格发现功能。
To cure a structural flaw: a chronic allowance surplus that wrecked the price signal. The crisis depressed emissions while allocation rules stayed frozen, outstanding spare allowances once piled past two billion tonnes, and prices sank until they no longer rewarded abatement investment. Running automatically since 2019, the reserve diverts twenty-four percent of circulating allowances above a threshold into storage each year (ten percent from 2024) and returns them through auctions once circulation falls below the floor - an automatic stabiliser on supply that restores scarcity and price discovery without reopening legislative negotiations.

中国全国碳市场为何不给电厂定绝对排放上限,而是按每度电的碳排放基准发免费配额?这种强度型设计换来了什么、牺牲了什么?
Why does China's national carbon market hand out free allowances via emissions-intensity benchmarks per unit of electricity instead of setting an absolute cap - and what does that design gain and give up?
它按单位发电量的碳排放基准免费发放配额,对冲经济与电力的增长不确定性:发电量上涨,配额随之增加,供电不会被碳价卡住。换来的是产业平稳与近乎百分之百的履约率,牺牲的则是约束刚性——配额整体偏松,碳价远低于欧盟,减排集中在少数落后机组,属相对减排而非绝对减排。欧盟ETS正相反,先立逐年收紧的总量上限,再靠拍卖让价格去执行。两种设计折射发展阶段之别:一边稳中降碳,一边硬性封顶。
Allowances are issued free against benchmarks for emissions per unit of electricity generated, hedging uncertain growth in both the economy and power demand: when output expands, allowances expand too, so supply is never squeezed by the carbon price. The reward is industrial stability and near-total compliance; the sacrifice is weak discipline - allocations stay comparatively generous, the carbon price sits far below Europe's, and cuts concentrate on a lagging minority of plants, delivering relative rather than absolute reductions. The EU ETS works in reverse: a tightening absolute cap comes first, and auctions let the price enforce it. Each design mirrors its stage of development - gradual decarbonisation versus a hard ceiling.

欧盟推出碳边境调节机制(CBAM)针对什么问题?进口商凭什么要为产品的隐含碳排放付费?
What problem does the EU's Carbon Border Adjustment Mechanism target, and on what grounds must importers pay for the embodied carbon of their products?
目的在堵住「碳泄漏」。若碳价只压在欧盟境内产业头上,钢铁、水泥、铝、化肥等高排放生产便会迁往气候政策宽松的国家,产品再返销欧洲,减排沦为纸面转移。为此进口商须申报钢、铝、水泥、化肥、氢与电力等产品的隐含碳排放,2023年10月先进入过渡申报期,2026年起购买价格挂钩碳配额拍卖均价的CBAM证书,同时境内免费配额逐年退坡,使内外碳成本对等。
Its purpose is to plug carbon leakage. If carbon prices press only on producers inside the EU, emission-intensive making of steel, cement, aluminium and fertilisers simply migrates to lenient jurisdictions and the products flow back, shifting pollution rather than cutting it. Importers must therefore declare the embedded emissions of covered goods - iron, steel, cement, fertilisers, hydrogen and electricity. A transitional reporting phase opened in October 2023; from 2026 they buy CBAM certificates priced off the average ETS auction while free allowances for domestic plants taper away, levelling carbon costs inside and outside.

碳排放权交易体系(如欧盟EU ETS)依据什么原理运作?总量上限如何设定,碳价又是怎样形成的?
On what principle does an emissions trading system such as the EU ETS operate, and how are its cap set and its carbon price formed?
核心是「总量控制与交易」。监管方先为电力等覆盖行业设定逐年收紧的排放上限,配额经免费发放或拍卖分给企业;每排放一吨CO₂须上缴一份配额,减排成本低的企业出售富余配额获利,成本高的企业购入,交易形成的碳价即社会的边际减排成本,从而以最小总成本完成既定减排量。欧盟碳市场2005年启动,目前覆盖约四成欧盟温室气体排放。
Cap-and-trade. The regulator fixes a declining ceiling on emissions for covered sectors such as power generation and allocates allowances free of charge or by auction; every tonne of CO2 emitted must be covered by one surrendered allowance. Firms whose abatement is cheap sell spare allowances for profit while those facing costly cuts buy them, so trading turns the marginal cost of abatement into the observed carbon price and achieves the agreed emission reduction at minimum overall cost. Launched in 2005, the EU ETS now covers roughly forty percent of the bloc's greenhouse-gas emissions.
