Using corporate social responsibility benchmarking framework to identify and assess corporate social responsibility trends of real estate companies owning and developing shopping centres

Shopping centres that include retail activities have come in for criticism as to their environmental, architectural and social impacts. However, the sector has been applying corporate social responsibility (CSR) practices. In an attempt to identify the best practices regarding CSR and trends therein we developed a CSR benchmarking of companies from the real estate sector owning and developing shopping centres. Based on information from websites, annual, environmental and sustainability reports, and customer services department’s information, in 2004 and 2010, a comparative CSR benchmarking was performed on 23 real estate companies with shopping centres based in Europe, China, Australia and the USA. The CRS benchmarking framework focused on reported CSR practices and included categories and sub-categories of evaluation in four domains: (1) external results, (2) internal results, (3) management processes and (4) learning and innovation. The framework was inspired by the sustainability balanced scorecard structure. The United Kingdom real estate sector’s companies studied did relatively well when evaluated by the framework used in this study. The highest ranked real estate companies applied sustainable or environmental buildings standards and did show a commitment to transparency and CSR disclosure. The positive evolution of CSR practices in the 23 companies studied in 2004 and 2010 may reflect efforts to improve competitiveness and the reputation of the companies with shopping centres through CSR initiatives.     

The influence of a voluntary fee in the consumption of plastic bags on supermarkets from Madeira Island (Portugal)

Since 2007, some supermarkets in Portugal have voluntarily abolished the free distribution of plastic bags, implementing a symbolic charge of €0.02 each at the same time that others still offer free plastic bags. This study assesses the influence of this voluntary measure on the reduction of plastic bags consumption, comparing clients from supermarkets that have adopted it with others who have free distribution. The reutilisation of bags reached 37% in supermarkets where customers pay a fee and was absent in supermarkets where plastic bags are free. Even the abstention of using bags, when clients buy only few products, is significantly higher in supermarkets where there are charges for plastic bags. The 2 cents charged has also induced a significant increase in optimal use of plastic bags since 52% of clients that pay for plastic bags use them so they are almost full, but only 17% do the same when they are free. Taken together, the different effects of charging for plastic bags represents a potential reduction of 64%. A mandatory tax on plastic bags is an important measure to reduce substantially the number of plastic bags consumed and to improve sustainability through the reduction of environmental, economic and social costs of pollution and waste management.     

Production of biodiesel from waste frying oils

Waste frying oils transesterification was studied with the purpose of achieving the best conditions for biodiesel production. Transesterification reactions were carried out for 1 h using waste frying oils (WFOs), methanol, and sodium hydroxide as catalyst. In order to determine the best conditions for biodiesel production, a series of experiments were carried out, using methanol/WFO molar ratios between 3.6 and 5.4 and catalyst/WFO weight ratios between 0.2% and 1.0%. For oils with an acid value of 0.42 mg KOH/g, results show that a methanol/WFO ratio of 4.8 and a catalyst/WFO ratio of 0.6% gives the highest yield of methyl esters. Furthermore, an increase in the amount of methanol or catalyst quantity seems to simplify the separation/purification of the methyl esters phase, as showed by a viscosity reduction and an increasing purity to values higher than 98% for methyl esters phase.     

The clustering conditions for managing creative tourism destinations: the Alqueva region case,Portugal

The paper discusses conditions and format of a cluster model to support the management of a potential creative tourism destination in a setting where regional cross-sectoral collaboration is lacking. Creative tourism development requires a flexible framework and a healthy collaboration environment, more so when associated with resources shared by several stakeholders. This article focuses on the tourism potential of archaeological knowledge discovered during the environmental impact assessment of the Alqueva dam (Alentejo, Portugal). Interviews were conducted with 38 regional actors in the tourism and heritage sectors, as well as the dam developers and the companies responsible for archaeological interventions. Findings indicate that the lack of specific local policy addressing archaeological heritage hampers its potential use for tourism development, which is further aggravated by the absence of stakeholder communication and cooperation. A conceptual cluster model for the management of creative tourism destinations based on heritage resources and other local resources is proposed.
