Water‐Energy Nexus
The assessment of energy efficiency in water facilities is receiving increasing attention as a key strategy in the transition toward an energy‐neutral urban water cycle. This study evaluates the energy efficiency of 146 drinking water treatment plants (DWTPs) in Chile by applying a latent class stochastic frontier analysis (LCSFA) to account for both observable and unobservable sources of heterogeneity. Unlike traditional models that assume homog…
Assessing Eco‐Efficiency in Municipal Solid Waste Management Integrating Heterogeneity
The measurement of eco‐efficiency in the municipal solid waste (MSW) sector has garnered significant attention due to the substantial environmental impacts of unsustainable MSW management and the high operational costs associated with public service provision. Given the heterogeneous nature of municipalities providing MSW services, a robust method is necessary to account for technological differences when assessing eco‐efficiency. This allows for…
Assessing Eco‐Efficiency and the Cost of Carbon Abatement in Wastewater Treatment
Wastewater treatment plants (WWTPs) play a critical role in protecting public health and the environment but are also contributors to carbon emissions. Improving the eco‐efficiency of WWTPs is essential for advancing sustainability in the sector. This study proposes a parametric approach using stochastic frontier analysis to evaluate the eco‐efficiency of 108 WWTPs in Spain and estimate the marginal cost of reducing GHG emissions. The eco‐efficie…
Evaluating the Sustainability of Water and Sanitation Services
Benchmarking the sustainability of water utilities (WUs) in the provision of water and sanitation services is essential for addressing global sustainability goals. This study proposes a water utility sustainability index (WUSI), which was estimated for a sample of 29 WUs in Chile. To evaluate the impact of weighting methodologies on sustainability assessments, two approaches were applied: the benefit of doubt (BoD) method and the analytic hierarc…
The Influence of Environmental Variables on the Carbon Performance of Water Companies Across Time
One of the main challenges that water companies face is to reduce carbon footprint in their transition to carbon neutrality. Past research assessing carbon performance of water companies has mostly ignored heterogeneity among the water companies evaluated. To overcome this limitation, this study employed a parametric metafrontier approach to assess and compare carbon performance of a sample of English and Welsh water companies, embracing water an…
Benchmarking technical efficiency of water utilities in Chile under heterogeneity
Eco-efficiency approach in sustainable waste management
Municipalities require eco-efficiency in managing solid waste to enhance sustainability and achieve a circular economy. Despite the relevance of waste statistics, there is high data uncertainty, which limits attempts to benchmark eco-efficiency in this sector. To overcome this limitation, the data envelopment analysis tolerance method was used to evaluate the eco-efficiency of solid waste management for a sample of municipalities in Chile. For ea…
Energy efficiency evaluation of wastewater treatment plants
Estimating the eco‐efficiency of urban waste services towards sustainable waste management
Assessing the eco‐efficiency of municipalities regarding the provision of solid waste services is a useful tool for improving its sustainability. However, robust, and reliable methods are needed to benchmark the performance of municipalities. Data envelopment analysis (DEA) methods typically used to assess the eco‐efficiency of municipal solid waste (MSW) service providers. However, the variables used in the eco‐efficiency assessment bear distinc…
The evolution of benchmaking the carbon efficiency drinking water companies in England and Wales
Water utilities face the challenge of transitioning to a low-carbon urban water cycle while reducing operational costs. This study evaluates the static and dynamic carbon efficiency of a sample of water companies from 2013 to 2018 operating in England and Wales. Each company was evaluated relative to itself and its peers using cross-efficiency Data Envelopment Analysis techniques. The results showed that the carbon performance of the water indust…
Estimating the impact of carbon inefficiency and overuse of energy on the economics of water companies
In the face of climate change, it becomes crucial to motivate action and policies within water companies towards achieving carbon neutrality. Estimating the economic consequences of inaction can be a compelling catalyst for change. In this study, the carbon inefficiency and overuse of energy among a selection of English and Welsh water companies were assessed, along with their impact on the operational costs of producing and delivering drinking w…
Profit productivity change in the English and Welsh water sector
Estimating energy costs and greenhouse gas emissions efficiency in the provision of domestic water
Reducing greenhouse gas (GHG) emissions and energy costs has been one of the main challenges faced by the water sector. This study provides a quantification of energy costs and GHG emissions efficiency of a sample of the English and the Welsh water companies over the period of 2013-2018. In doing so, the multi-directional data envelopment analysis (DEA) method was employed, which allows the quantification of the potential savings in energy costs …
Estimating the cost efficiency and marginal cost of carbon reductions in the production of drinking water
Measuring the eco-efficiency of the provision of drinking water by two-stage network data envelopment analysis
Performance assessment of the Chilean water sector
Eco-Efficiency of the English and Welsh Water Companies
Analyzing costs and greenhouse gas (GHG) emissions could be of great importance for the water utilities to supply water services in a healthy and sustainable manner. In this study, we measured the eco-efficiency of several water utilities in England and Wales by incorporating GHG as an undesirable output. For the first time, we evaluated the eco-efficiency of the water production process using robust cross-efficiency data envelopment analysis (DE…
