To enhance the precision of the simulations, sector-specific capital-energy substitution elasticities are empirically estimated using data from the 2022 Vietnam Enterprise Survey and incorporated into the model. Unlike previous studies that rely on subjective assumptions, this study rigorously calculates the minimum carbon tax levels required to meet Vietnam’s unconditional and conditional Nationally Determined Contribution (NDC) targets by 2030. The simulation results suggest that achieving the unconditional NDC target would require a carbon tax of approximately USD 10 per ton of CO₂, leading to a modest GDP contraction of 0.12%. In contrast, fulfilling the conditional NDC target would necessitate a higher carbon tax rate of USD 38 per ton of CO₂, associated with a GDP decline of 0.81%. Emission-intensive sectors, notably coal mining, cement manufacturing, and metallurgy, are disproportionately affected, whereas clean technology industries demonstrate expansionary responses. In addition, illustrative revenue recycling scenarios indicate that reallocating carbon tax revenues can partly offset welfare losses and slightly cushion GDP impacts. Taken together, these findings emphasize the critical importance of a phased carbon tax implementation strategy, complemented by targeted support measures for vulnerable sectors, to balance emission reduction objectives with sustainable economic growth.</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"7 ","pages":"Article 100238"},"PeriodicalIF":5.6,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This discourse achieved hegemony by instrumentalizing climate change science, making it appear politically neutral and ecologically imperative. This research reveals three key limitations of this hegemonic discourse, namely depoliticization, Westen-centrism, and obfuscation of unequal power relations. These limitations compound to shield the hegemonic energy transition discourse from political and intellectual scrutiny, which in turn risks perpetuating colonial and racialized global hierarchies characteristic of the fossil fuel-based energy system. This paper joins the literature which seeks to highlight how power is embedded in energy discourses and practices. This paper advances a conceptual contribution to this literature through proposing the use of Foucauldian governmentality. This research demonstrates that governmentality is better equipped than post-colonialist perspectives to simultaneously historicise and contextualise unequal power relations to account for contingency, resistance, and agency. This paper therefore advocates for the operationalization of governmentality to account for post-colonial structures without jettisoning an awareness of the role of individual agency in reshaping energy systems and subverting attendant power relations. By doing so, governmentality-minded investigations can transcend interest-based perspectives to enable policy-relevant findings with the potential to transform the status quo</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"7 ","pages":"Article 100230"},"PeriodicalIF":5.6,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Accessing clean vehicles: How dealer requirements limit equity and emissions benefits under the inflation reduction act’s preowned EV credit","authors":"Lucas Woodley ,&nbsp;Chung Yi See ,&nbsp;Daniel Palmer ,&nbsp;Ashley Nunes","doi":"10.1016/j.egycc.2025.100234","DOIUrl":"10.1016/j.egycc.2025.100234","url":null,"abstract":"<div><div>Preowned vehicles are disproportionally purchased by low-income households, regardless of propulsion type. Low-income households have long faced financial challenges to purchasing electric vehicles (EVs), especially absent financial incentives. Yet, those households would disproportionally benefit from EV adoption given the operating cost savings offered by electrification. To help realize this benefit, provisions of the 2022 Inflation Reduction Act (IRA) offer preowned EV purchasing incentives. How effective might these efforts be, and how might eligibility requirements governing procurement pathways impact such efficacy? We address these questions by combining nationally representative data from the U.S. Census Bureau, the National Household Travel Survey, and a detailed vehicle purchase dataset together with lifecycle emissions estimates derived from the Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model. Using these data, we evaluate how the IRA’s preowned EV credit influences equity and emissions outcomes, focusing on the dealer-only eligibility requirement that impacts which households can benefit. Our findings are fourfold. First, we demonstrate that although low-income households are more likely to benefit from preowned EV purchasing incentives offered by IRA, up to 8.4 million low-income households may be ineligible owing to heterogeneity in vehicle procurement pathways (i.e., where a vehicle is purchased from). Second, we show that program ineligibility risks preventing up to 113.9 million tons of CO₂e in lifecycle emissions reduction benefits from being realized, reducing total emissions benefits by approximately 31%. Third, we find that procurement pathways interact with vehicle price. More expensive preowned vehicles are purchased directly from commercial dealers, while less expensive preowned vehicles are purchased from private sellers. These procurement pathways matter because qualification for IRA’s incentives necessitates purchasing solely from commercial dealers (versus private sellers). Fourth, we demonstrate that while incentives motivating preowned vehicle purchases from commercial dealers may be effective if the vehicle costs more than $6000, this effectiveness diminishes at higher price points. The implications of our findings on decarbonization efforts and energy policy are discussed.</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"7 ","pages":"Article 100234"},"PeriodicalIF":5.6,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of the initiatives is assessed by calculating their potential impact on greenhouse gas emissions, assuming full implementation by the signatories. Their alignment with the Paris temperature goals is assessed against 2 °C and 1.5 °C pathways. Two scenarios, based on signatory and full global participation, are compared with current policy scenarios and pathways consistent with below 2 °C and 1.5 °C (high overshoot). If country signatories implemented initiative targets domestically, projections for 2030 to 2050 are generally more ambitious than current policies, potentially decreasing global emissions by about 11%. Comparing full global implementation to below 2 °C or 1.5 °C pathways, the results are mixed. By 2030, most initiative goals align with 2 °C, but certain thematic areas are missing. A number of initiatives demonstrate ambition beyond 1.5 °C pathways, questioning their feasibility. Achieving all global initiative targets by 2030 consistent with the below 2 °C and 1.5 °C (high overshoot) pathways requires 5–8% additional reductions. Realising the full potential of these initiatives necessitates increasing ambition for specific goals by 2030, increasing and clarifying long-term ambition, expanding thematic coverage, and requiring concrete climate action plans.
