In English, the word 鈥渟obriety鈥� has no place in discussions on sustainable development. However, in France, 蝉辞产谤颈茅迟茅 is a sustainable development concept that has existed for decades. The concept first came about as an energy conservation measure in response to the oil shocks of the 1970 and was conceptualized in 2001 by the n茅gaWatt Association, an energy transition think tank. 厂辞产谤颈茅迟茅 is one of the three fundamental pillars of the energy transition approach promoted by n茅gaWatt, alongside efficiency and renewable energy, and is defined as a moderation approach to the services provided by energy consumption as opposed to overconsumption, constitutes both a necessity and an opporunity1 (Association n茅gaWatt, 2016). When applied to energy, 蝉辞产谤颈茅迟茅 茅nerg茅tique places an explicit value on using energy responsibly overall, including by reducing overall energy use where necessary for the greater social good, beyond privileging more efficient technologies and equipment (Bourliaguet, 2025).

厂辞产谤颈茅迟茅 in the context of sustainable development is a term that is specific to French, but the concept behind it holds international significance across languages. A similar term in English would be 鈥渟ufficiency鈥�, and related concepts include 鈥渇rugality鈥�, 鈥渟imple living鈥� or 鈥渄ownshifting鈥� (C茅zard & Mourad, 2019). In other languages, similar terms include suffizienz or ausreichend in German, sufficienza or consumo critico in Italian, and 迟颈濒迟蝉迟谤忙办办别濒颈驳丑别诲 or 产忙谤别诲测驳迟颈驳丑别诲 in Danish, which all centre around the concept of what is enough; the terms 鈥渟obriety鈥�, 狈眉肠丑迟别谤苍丑别颈迟, 蝉辞产谤颈别迟脿, and 忙诲谤耻别濒颈驳丑别诲 are rarely used outside of contexts referring to the limitation of alcohol and drugs in these languages. However, each of these terms hold their own meaning and connotations that are different from one another, and none carry the same connotations as 蝉辞产谤颈茅迟茅 in French (Flipo, 2024). In English, for example, sufficiency is not a perfect translation because it does not carry a connotation of intentional behaviour change, maturity, or even necessarily a desirable reduction of excess, whereas all three of these connotations are carried by the word 蝉辞产谤颈茅迟茅 in French.

厂辞产谤颈茅迟茅 is more than just energy conservation. Where energy conservation means using less energy through behaviour changes such as turning off lights, lowering the thermostat, or taking shorter showers, 蝉辞产谤颈茅迟茅 expands on this by intentionally reducing demand to what is actually needed. This includes energy conservation measures, but it also includes changing norms about what is enough and redesigning how services are provided. Bourban (2022) specifically calls attention to the importance of understanding 蝉辞产谤颈茅迟茅 as a virtue, rather than a sacrifice, an understanding which 鈥渋s based on the ethical principle of self-limitation that guides every day choices鈥� (Bourban, 2022, p. 19).

In addition, the distinction of 蝉辞产谤颈茅迟茅 from the notion of efficiency is important to note. Energy efficiency, commonly used in discourse related to energy sustainability in English, is about doing more with less by putting a premium on the goal of increasing the value of the service provided for each unit of energy. The Intergovernmental Panel on Climate Change defines this as 鈥渢he ratio of output or useful energy or energy services or other useful physical outputs obtained from a  system, conversion process, transmission or storage activity to the input of energy鈥� (IPCC, 2022, p. 1801). It emphasizes using technology, materials, and design to reduce the energy input per unit to deliver the same service (e.g., heating and cooling). By contrast, 蝉辞产谤颈茅迟茅 seeks to normalize reducing demand so that people use only what they really need, and is focused on more qualitative, social elements such as habits, practices, wellbeing, ecological limits or justice (Bourliaguet, 2025). However, this does not mean that one concept should be used over another. While efficiency can reduce environmental impacts, it may not be enough on its own because improvements in efficiency can sometimes lead to rising energy consumption 鈥� a phenomenon called the rebound effect or Jevons paradox (York et al., 2022). 厂辞产谤颈茅迟茅 can attenuate this effect by directly addressing demand/consumption, rather than just the means by which that demand is met. In France, it is understood at a national level that both approaches should be used as complements in the country鈥檚 energy transition pathway towards carbon neutrality, through selected savings rather than forced cuts, in a context of opening up one鈥檚 way of thinking about climate action and intentional behavioural change (C茅zard & Mourad, 2019; Gouvernement de France, 2022).

While 蝉辞产谤颈茅迟茅 is not free of criticisms, such that it fails to consider distributive equity among different socioeconomic groups and that low-income households already practice and have practiced 蝉辞产谤颈茅迟茅 principles for economic reasons (Flipo, 2024), it provides value as a term of transition because it provides a holistic and deliberate framing for change. The term is also useful because transitions are not only technical; they are social and moral as well. Compared to other similar terms in other languages, 蝉辞产谤颈茅迟茅 is unique in that it is the only one of the terms which is firmly positioned in a country鈥檚 social and political debate across different academic, expert, and philosophical backgrounds (Flipo, 2024). 厂辞产谤颈茅迟茅 was inscribed in the Energy Transition Law in 2015, and, more recently, in the national Energy 鈥淪obriety鈥� Plan (Plan de 厂辞产谤颈茅迟茅 脡nerg茅tique) in 2022. The economic shocks related to the onset of the Russia-Ukraine war and United States-Israel (US-Israel) war on Iran (France 24, 2026) has led to a warning from the head of the International Energy Agency that the world is currently facing an energy crisis more severe than the oil shocks of the 1970s (France 24, 2026), providing further justification for the need for approaches focusing on reducing energy demand.  

Interest in 蝉辞产谤颈茅迟茅 as a term of transition has led to research that investigates how this concept is applied in practice across two generations of 茅肠辞辩耻补谤迟颈别谤蝉 (ecodistricts or econeighbourhoods) in Paris, France. The City of Paris has achieved remarkable acceleration of its climate and ecological transition actions in recent years, drawing the attention of sustainability advocates, researchers and practitioners (51社区黑料 et al., 2024; Holden et al., 2021). Through comparative interpretive analysis, this research examines shifts in the use of French language terminologies to advance sustainable urban development from a first generation 茅肠辞辩耻补谤迟颈别谤 project, Clichy-Batignolles, initiated in 2002, to a second generation 茅肠辞辩耻补谤迟颈别谤 project, Saint-Vincent-de-Paul, currently in development. Rather than examining the merits of 蝉辞产谤颈茅迟茅 or the 茅肠辞辩耻补谤迟颈别谤蝉 in question, this research identifies the types of energy and materials sustainability strategies they apply and how and if these have changed as a result of increasing promotion of a 蝉辞产谤颈茅迟茅 in French law and policy over the last decade. This offers direct implications for understanding the evolution of policy and planning tools toward greater contextual effectiveness in guiding change, revealing the importance of some untranslatable concepts centering on the concept of 蝉辞产谤颈茅迟茅.

Through a translanguaging process, this research also demonstrates the value of examining sustainable development approaches beyond English in order to expand our repertoire of social and political levers for ecological transition. This offers researchers and practitioners interested in understanding the cultural aspects of more and less appealing urban change proposals a new lens with potential for better insight, as the need for climate safe and more sustainable development pathways becomes more urgent.
