Abstract Bangladesh has developed a power generation expansion plan up to 2041. However, the plan did not fully consider the importance of sustainable development. This paper addresses this limitation and assesses both historical and future sustainability trends of Bangladesh's power generation system, as well as the sustainability of the Power System Master Plan (PSMP-2016) through multi-criteria decision analysis (MCDA) with respect to social, environmental, and economic dimensions of the sustainability framework. Out of a total of 19 sustainability indicators, there were 10 social, 4 environmental, and 5 economic indicators taken into account. It was found that Bangladesh's future power generation sector's sustainability is going to deteriorate from its present situation. Results of the analysis show that the sustainability index of 0.3769 in 2016 is going to degrade to 0.3249 in 2041. Most importantly, economic indicators dominate the sustainability measures, compared with social and environmental indicators. Thus, improvements in the economic indicators will result in a substantial increase in the sustainability index of the country's power generation sector. This indicates that energy policies need to be designed in such a way that a balance is achieved between all three dimensions to ensure a sustainable future electricity generation system. A similar analysis can also be applied to other countries where future power generation expansion planning is underway. Highlights • Sustainability assessment of power generation sector of Bangladesh. • Demonstrates sustainability indices for different power generation technologies. • Assesses sustainability trends of the future electricity generation system. • Supports sustainable power generation related policy development.

Sustainability assessment as an ex ante tool for directing decision-making towards sustainability has emerged in a diverse range of forms across the world over the past decade or so. This broad practice of sustainability assessment embraces a wide and continually evolving range of processes, making the field potentially conceptually confusing and difficult to navigate. In recognition of this, there have been numerous attempts to develop conceptual frameworks to make sense of the diversity of practice. Through a process of literature review and reflection upon practice, this paper builds on earlier work, including our own, to develop a new descriptive conceptual framework for sustainability assessment. The conceptual framework distinguishes two dimensions of sustainability assessment, each with several sub-dimensions: sustainability concept (with sub-dimensions of underpinning sustainability discourse and representation of sustainability) and decision-making context (with sub-dimensions of subject of assessment, decision-question and responsible party). Drawing upon further literature, several examples of different approaches are then identified for each sub-dimension, demonstrating the range of approaches evident within current and emerging global practice. Within the ‘sustainability concept’ dimension, the first sub-dimension calls for critical reflection upon what the normative goal of the sustainability assessment is, while the second refers to how the concept of sustainability is represented in the decision-making process through the use of indicators. Although these two sub-dimensions are closely related their distinction is a key feature of the conceptual framework. The second dimension describes the practical context of a sustainability assessment. The proposed new conceptual framework enables a particular body of practice to be located within the broader field, as we demonstrate by categorising five examples of sustainability assessment according to the framework. We believe this framework has value to both researchers and practitioners, as a structure to guide sustainability assessment research and analysis and as the basis for comparing bodies of sustainability assessment practice within the range of possibilities defined by the contours of the framework. The framework encourages reflective practice, particularly in relation to how the concept of sustainability is understood and embedded within the process, and what the practice might deliver. This new conceptual framework is presented as a relatively simple road map and guide as sustainability assessment theorising and practice enters its second decade. [ABSTRACT FROM AUTHOR]

Abstract: Since the Rio Declaration in 1992, international institutions, governments and NGOs have promoted sustainability indicators as a tool for providing policy mechanisms that dictate development decision-making. The expert approach, also known as reductionist, has been the most used in the processes of sustainability evaluation; this approach has been criticized for its lack of holistic vision to evaluate a system. A participatory approach has been promoted in order to counteract this type of limitation. This paper presents a case study of a participatory assessment of sustainability in a local community inside a natural protected area; its objective is to attempt to answer if, from local knowledge, is it possible to generate a sustainability local assessment system. The process included the active participation of the inhabitants of Agua Blanca community, located within the Nevado de Toluca National Park (NTNP) in Mexico''s central highlands. A framework was used to identify and select sustainability indicators, which was divided into four phases: the description of the system, the identification of the sustainability objectives, the selection of indicators, and the measurement of the progress toward the sustainability objectives. As a result, 64 indicators were identified, which were classified into three pillars of sustainability and its interactions. The participatory approach aided in the evaluation of diverse elements within the system, without limiting itself to one element or dimension of sustainability in particular. Most of the indicators corresponded to the environmental dimension of sustainability, which reflects the level of interaction the community has with its environment. The indicators proposed by villagers, as a whole, were not considered technically appropriate; therefore the need for a selection indicator process was reaffirmed. The process described here is an opportunity to strengthen the self-organization of the communities, reinforce local management, and contribute to the generation of mechanisms of cooperation and processes of co-management of the natural protected areas.
