- Mapping Fuel Poverty in PortugalPublication . Simoes, Sofia G.; Gregório, Vera; Seixas, Júlia; DCEA - Departamento de Ciências e Engenharia do Ambiente; CENSE - Centro de Investigação em Ambiente e SustentabilidadeWe defined a novel methodology to assess the potential fuel poverty of residential dwellings at LAU2 level combining data on income, level of education, unemployment rate, and number of inhabitants above 65 years old, with both the space heating and cooling gap estimated per household typology. We create an indicator of the share of potential fuel poor inhabitants in each LAU 2 region. We implemented this methodology for 29 municipalities in Portugal. On average 22% of the inhabitants are potentially fuel poor regarding their dwellings' space heating and 29% regarding space cooling. There is a large variation across the country.
- Environmental management and mudit training at the New University of Lisbon by University-Industry co-operationPublication . Melo, João Joanaz deThis paper describes the experience of a joint university-industry effort, under the course "Project on Environmental Management and Auditing", in the Environmental Engineering program at the New University of Lisbon. In this course, students are divided in audit teams and perform environmental audits in operating companies or institutions. The course has shown remarkable success, in all respects. The total number of case studies so far is 50. They have covered many fields of activity, including among others: chemicals, cement, electricity, gas, metalwork, pulp and paper, auto components and assembly, construction works, waste treatment, shopping centres, fuel and chemical storage, public and cargo transportation, an airport, military bases, insurance business, tourism, a natural preserve, zoos and aquariums, and the UNL Campus itself at Caparica. Relations with the audited companies or institutions have been quite positive, by means of carefully drafted protocols that ensure a mutually acceptable methodology and scope of the audit, along with undisclosure clauses. We have found this a very positive experience for all concerned: the students, the companies or institutions and the University.
- Strategic environmental assessment in Tróia (Portugal)Publication . Melo, João Joanaz de; Andrade, Francisco; Ferreira, M A; Gomes, N; Leitão, P; Pinto, M JOver the last two decades, the Tróia peninsula (SW coast of Portugal) has been designated by the Portuguese authorities both as a protected area and as an area of tourism development. The private investor that took over the tourism developments in Tróia asked the Institute of Marine Research (IMAR) to undertake an SEA, to help frame the design and management of the future resort. SEA results were changed by local/central government decisions, granting “more” than stakeholder/owner’s proposal, in terms of loads and densities. This process, as well as the main characteristics and results of the SEA, are presented and discussed.
- Static laws in dynamic environments (bridging science to legislation)Publication . Melo, João Joanaz de; Ferreira, M A; Andrade, FranciscoOf the numerous problems affecting environmental management, inadequate base legislation is but one. However, it is a key factor that should deserve greater attention both from scientists and policy-makers, since it may severely impair effective management efforts, especially in such dynamic environments as coastal areas. The case of the Tróia peninsula (SW Portugal) is presented to illustrate how (inadequate) legislation effectively impairs management. The need for a new praxis in policy-making is discussed.
- Application of the EcoBlock method to eco-design - electric hand dryers versus paper towelsPublication . Melo, João Joanaz de; Macedo, L; Galvão, AThe EcoBlock method is an environmental performance tool that allows the comparison of products, projects or organizations. It is based on seven indicators: water extraction, resource extraction, land use, greenhouse gases (GHG), other air pollution, water pollution, and waste. A simplified life cycle analysis approach is adopted. The indicators may be aggregated into a single index, inspired in the Ecological Footprint concept. In this case study we compare the environmental performance of two hand-drying alternatives – paper towels or electric dryers. Both techniques present similar results. The pattern of use was found to be a variable of key importance in the comparison: lesser use of towels per drying would tip the balance in favour of the towels, more efficient dryers or lower impact energy sources would tip the balance in favour of the dryers. Electricity consumption proved to be the largest pressure generator in both alternatives.
