能效中的「回弹效应」（杰文斯悖论）是什么？它会如何抵消节能？
What is the rebound effect (Jevons paradox) in energy efficiency and how can it offset savings?
回弹效应指能效提升降低单位成本后，使用量增加，部分乃至全部抵消节省的能源。极端情况下（杰文斯悖论），效率提高反而使总消耗上升，如 19 世纪燃煤效率提升反而扩大用煤。
The rebound effect occurs when efficiency lowers per-unit cost, so usage rises and partly or fully cancels the energy saved. In the extreme (Jevons paradox), higher efficiency increases total consumption—as 19th-century coal efficiency gains expanded coal use.

家庭热泵相较燃气锅炉的减排收益为何高度依赖电网碳强度？
Why does a heat pump's emission benefit hinge on grid carbon intensity?
热泵以电力搬移热量，能效（COP）可达3–4倍，但其排放等于耗电量乘以电网排放因子；在煤电占比高的电网，热泵减排有限甚至高于高效燃气，只有电网清洁化后优势才充分释放。
A heat pump moves heat electrically at COP 3–4, but its emissions equal electricity used times the grid emission factor; on coal-heavy grids the savings are slim or worse than efficient gas, and only materialize as the grid cleans up.

循环经济与个人消费端的' rebound effect'如何抵消环保行为？
How does the rebound effect offset green consumer behavior?
节能家电省下的电费可能诱使更多使用（直接回弹），或把省下的钱花到其他高碳消费（间接回弹），使预期减排打折；系统层面需配合碳价与总量约束，才能避免个人努力被行为反弹吞噬。
Efficient appliances save money that may invite more use (direct rebound) or be spent on other carbon-intensive goods (indirect rebound), eroding expected savings; only with carbon pricing and caps can individual effort avoid being swallowed by behavioral rebound.

太阳能电池板的回收问题是什么？
What is the recycling problem with solar panels?
晶硅组件含玻璃、铝和少量银、硅及含氟背板，层压结构使分离困难且经济价值偏低。随着早期装机进入退役期，废旧组件量将快速上升。机械破碎加分选或热解可回收大部分材料，但需完善回收体系。
Crystalline panels contain glass, aluminium and small amounts of silver, silicon and fluorinated backsheets; their laminated structure is hard to separate and low in value. As early installations retire, end-of-life volumes will rise fast. Crushing plus sorting or pyrolysis can recover most materials, but a sound recycling system is needed.

热泵技术为何比传统取暖更节能？
Why is heat-pump technology more efficient than conventional heating?
热泵不直接燃烧产热，而是用少量电能把外界低温热搬到室内，能效比可达三倍以上的热量输出。它还可反向制冷，一机两用。其减碳效果取决于电网清洁度，绿电比例越高越环保。
A heat pump does not burn fuel for heat; it uses a little electricity to move low-temperature heat indoors, delivering over three times the energy as output. It can reverse for cooling, doing both jobs. Its carbon benefit depends on grid cleanliness; more green power means more savings.

'食物里程'是不是判断低碳饮食的唯一指标？
Is 'food miles' the only metric for a low-carbon diet?
不是。生产环节的排放常远大于运输：牛肉、乳制品的温室气体强度远高于多数本地蔬果，远程海运的蔬果有时比本地大棚反季菜更低碳，因此应综合生产方式而非只看里程。
No. Production emissions usually dwarf transport: beef and dairy far exceed most local produce, and shipped vegetables can beat local heated off-season crops, so judge by production method, not miles alone.

What is greenwashing?
漂绿是企业夸大或虚假宣传环保表现，以误导消费者的行为，例如用绿色包装却无实质减排。它削弱真正可持续产品的信誉并扭曲市场。识别漂绿要看具体证据而非笼统的环保口号。
Greenwashing is when a company exaggerates or falsely claims environmental virtue to mislead consumers, such as green packaging with no real emission cuts. It undermines genuinely sustainable products and distorts markets. Spot it by demanding concrete evidence over vague eco-slogans.

素食饮食能减少多少碳足迹？
How much can a vegetarian diet reduce one's carbon footprint?
研究表明以植物为主的饮食可比高肉类饮食减少约两到四成的食物相关碳排放，牛肉和羊肉的排放尤其高。减少食物浪费和本地采购可进一步降低影响。饮食结构调整是个人减排最有力的手段之一。
Studies show plant-forward diets can cut food-related emissions by roughly 20 to 40 percent versus meat-heavy ones, since beef and lamb are especially high. Reducing food waste and buying local lowers impact further. Dietary shifts are among the most powerful personal mitigation actions.

什么是食物里程？
What is food miles?
食物里程指食物从生产地到消费地所运输的距离，常用来衡量流通环节的碳排放。但里程并非全部，生产方式的排放往往远大于运输，例如本地反季节温室菜可能高于外地应季菜。评估应结合全生命周期。
Food miles measure the distance food travels from production to consumption, often used as a proxy for transport emissions. But miles are not the whole story; production emissions usually dominate, so local off-season greenhouse produce can exceed seasonal imports. Assessment should use the full life cycle.

能效提升为什么有时并不能等比例降低总能耗？
Why does improving energy efficiency sometimes fail to cut total energy use proportionally?
这就是回弹效应：设备更省能意味着单位服务的成本下降，人们会用得更多，比如换装 LED 后延长照明时间，买了省油车后行驶里程增加，这是直接回弹；省下的钱转而消费其他能源密集商品，构成间接回弹。若整个经济的生产率因此提升、能源服务价格全面走低，宏观层面还可能出现更大规模的反弹，这一命题源自杰文斯对煤炭的观察。多数实证研究认为家用设备的直接回弹约在一到三成，因此能效政策依然有效，但需要与碳价或总量控制配合。
This is the rebound effect: more efficient equipment lowers the cost per unit of service, so people consume more of it — leaving LED lights on longer, or driving further in a fuel-sipping car — which is direct rebound, while money saved is spent on other energy-intensive goods, producing indirect rebound. If economy-wide productivity rises and energy service prices fall broadly, macro-level rebound can be larger still, a proposition traceable to Jevons's observations about coal. Most empirical studies place direct rebound for household devices at roughly 10–30%, so efficiency policy remains effective but works best paired with carbon pricing or a binding cap.
