The sweet spot in sustainability: a framework for corporate assessment in sugar manufacturing

The assessment of corporate sustainability has become an increasingly important topic, both within academia and in industry. For manufacturing companies to conform to their commitments to sustainable development, a standard and reliable measurement framework is required. There is, however, a lack of sector-specific and empirical research in many areas, including the sugar industry. This paper presents an empirically developed framework for the assessment of corporate sustainability within the Thai sugar industry. Multiple case studies were conducted, and a survey using questionnaires was also employed to enhance the power of generalisation. The developed framework is an accurate and reliable measurement instrument of corporate sustainability, and guidelines to assess qualitative criteria are put forward. The proposed framework can be used for a company’s self-assessment and for guiding practitioners in performance improvement and policy decision-maki

Current Methods for Calculating National Ecological Footprint Accounts 【特集論文 エコロジカル・フットプリント指標の現状と課題】

Departmental Bulletin PaperThe Ecological Footprint is a resource accounting tool that measures how much bioproductive land and sea is available on Earth, and how much of this area is appropriated for human use. The Ecological Footprint, human demand, and biocapacity, ecosystem supply, are both measured in units of global hectares, a hectare normalized to the average productivity of all bioproductive hectares on Earth. As of 2003, there are approximately 11.2 billion global hectares of area available. In that same year, humanity demanded products and services from the equivalent of 14.1 billion global hectares. This overshoot, if it continues, will put global ecosystems at serious risk of degradation or collapse. Humanity's Ecological Footprint is spread across six land use categories: cropland, grazing land, fishing grounds, forest, built-up area, and land for carbon absorption. Of these six, land for carbon absorption is the most significant globally, representing nearly one half of humanity's total Footprint. A concerted international effort to shrink human demand to within the limits set by nature will be an important component of any effort to create a sustainable future for all people.滋賀大学環境総合研究センター研究年報, 第4巻第1号, pp. 1-9departmental bulletin pape

Biocapacity and cost-effectiveness benefits of increased peatland restoration in Scotland

Ecological Footprint and biocapacity accounting is a widely-used ecological accounting framework which tracks human demand against the biosphere’s rate of regeneration. However, current national assessments do not yet include carbon-dense peatlands, hindering the evaluation of peatland biocapacity contributions. Also, the economic efficiency of peatland restoration is understudied and needed to inform land use decisions. We provide the first assessment of Scotland’s biocapacity and add peatlands as a novel land type. We then project the biocapacity impacts in 2050 of current peatland restoration targets and various alternative management scenarios. Finally, we estimate the cost per tonne of greenhouse gas abated of various peatland restoration scenarios, and compare this with estimates of afforestation mitigation costs from the literature. Our results show that Scotland’s per-person biocapacity exceeds the UK average by a factor of three. However, despite covering 25% of land area, peatland biocapacity increases Scotland’s biocapacity total by only 2%, while the Carbon Footprint of degraded peatlands increases Scotland’s ecological deficit by 40%. Current peatland restoration targets of the Scottish Government are estimated to reduce the national ecological deficit by only 9% in 2050. The cost-effectiveness of peatland restoration is context-dependent, and extremely cost-effective methods are applicable to peatland areas far exceeding current government restoration targets. Our findings provide land managers with evidence in favour of increased peatland restoration, both in terms of boosting biocapacity, and economic cost- effectiveness

Ecological footprint and appropriated carrying capacity : a tool for planning toward sustainability

There is mounting evidence that the ecosystems of Earth cannot sustain current levels of economic activity, let alone increased levels. Since some consume Earth’s resources at a rate that will leave little for future generations, while others still live in debilitating poverty, the UN’s World Commission on Environment and Economic Development has called for development that is sustainable. The purpose of this thesis is to further develop and test a planning tool that can assist in translating the concern about the sustainability crisis into public action. The research advances the concept of “Ecological Footprint” or “Appropriated Carrying Capacity” (EF/ACC) as a planning tool for conceptualizing and developing sustainability. To meet this purpose, I document the development of the EF/ACC concept, explore its potential use in public decision-making towards sustainability, apply the concept in a real world context, and finally, empirically analyze its usefulness to actors in the public domain. The research shows that the EF/ACC concept can link global social and ecological concerns to individual and institutional decision-making. Though the tool needs further refinement to make it readily applicable to the planning practitioners’ everyday decisions, it has proved useful as a conceptual tool for framing the sustainability challenges. More than 20 EF/ACC applications, by others and by me, range from environmental outdoor education for children to policy and project assessments for municipalities and regions. With these examples, EF/ACC has contributed to translating sustainability into concrete terms and to providing direction for planning toward sustainability.Applied Science, Faculty ofCommunity and Regional Planning (SCARP), School ofGraduat
