Life-cycle energy and greenhouse gas analysis of three building types in a resi...
Bastos, Joana; Batterman, Stuart A.; Freire, FaustoResidential buildings consume a large fraction of energy and thus represent a major opportunity for reducing energy requirements and greenhouse gas (GHG) emissions. This article presents a life-cycle energy and GHG analysis of three representative residential building types in a well-known area in Lisbon (Bairro de Alvalade). The life-cycle model focused on building construction, retrofit and use phases, applie...
Carbon footprint of particleboard: a comparison between ISO/TS 14067, GHG Proto...
Garcia, Rita; Freire, FaustoThis article aims to assess: i) the carbon footprint (CF) of particleboard produced in Portugal, and ii) the influence of different methodological issues in the particleboard CF calculation by comparing four CF methodologies (ISO/TS 14067; GHG Protocol Product Standard; PAS 2050; Climate Declaration). A life-cycle model was developed for particleboard (functional unit: 1 m3). Both cradle-to-gate and cradle-to-g...
Carbon footprint of apple and pear: orchards, storage and distribution
Figueiredo, Filipa; Castanheira, Érica Geraldes; Feliciano, Manuel; Rodrigues, M.A.; Peres, António M.; Maia, Filipe; Ramos, António; Carneiro, JoãoApple and pear represent 51% of fresh fruit orchards in Portugal. This paper presents a life-cycle (LC) greenhouse gas (GHG) assessment (so-called carbon footprint) of 3 apple and 1 pear Portuguese production systems. An LC model and inventory were implemented, encompassing the farm stage (cultivation of fruit trees in orchards), storage and distribution (transport to retail). The functional unit considered in ...

Life-cycle greenhouse gas emissions of portuguese olive oil
Figueiredo, Filipa; Coroama, Vlad C.; Ramos, António; Almeida, Arlindo; Ramalhosa, Elsa; Castanheira, Érica Geraldes; Peres, Fátima; Carneiro, JoãoThe main goal of this paper was to assess the greenhouse gas (GHG) intensity of olive oil production in Portugal. A life-cycle model and inventory were implemented for the entire production process, including a comprehensive analysis of olive cultivation, olive oil extraction, packaging, and distribution. Data originates from five differently-sized Portuguese olive growers and from a total of six olive oil mill...

Renewability and life-cycle energy efficiency of bioethanol and bio-ethyl terti...
Malça, João; Freire, FaustoBiofuels are expected to play an increasingly important role in the transportation market, as we search for ways to reduce fossil fuels depletion and emissions. However, the extent to which biofuel can displace petroleum-based fuels depends on the efficiency with which it can be produced. To demonstrate that biofuel has a positive energy balance--i.e. more energy is contained in the fuel than is used in the pro...
