The importance of the social dimension of sustainable development increased significantly during the last decade of the twentieth century. Industry has subsequently experienced a shift in stakeholder pressures from environmental to social-related concerns, where new developments in the form of projects and technologies are undertaken. However, the measurement of social impacts and the calculation of suitable indicators are less well developed compared to environmental indicators in order to assess the potential liabilities associated with undertaken projects and technologies.
The aim of this paper is to propose a Social Impact Indicator (SII) calculation procedure based on a previously introduced Life Cycle Impact Assessment (LCIA) calculation procedure for environmental Resource Impact Indicators (RIIs), and to demonstrate the practicability of the SII procedure in the context of the process industry in South Africa. Methods. A framework of social sustainability criteria has been introduced for the South African process industry.
The social sub-criteria of the framework are further analyzed, based on project and technology management expertise in the South African process industry, to determine whether the criteria should be addressed at project or technology management level or whether they should rather form part of an overall corporate governance policy for new projects and technologies. Furthermore, the proposed indicators for criteria that are considered appropriate for project or technology evaluation purposes are constrained by the type of information that is available, i. e. he calculation methodology relies on the availability of regional or national social information where the project will be implemented, as well as the availability of project- or technology-specific social information during the various phases of the project or technology development life cycle. Case studies in the process industry and statistical information for South Africa are subsequently used to establish information availability for the SII calculation procedure, demonstrate the SII method together with the RII method, and determine the practical use of the SII method.
Results and Conclusion. The case studies establish that social footprint information as well as project- and technology social data are not readily available in the South African process industry. Consequently, the number of mid-point categories that can be evaluated are minimal, which results in an impaired social picture when compared to the environmental dimension. It is concluded that a quantitative social impact assessment method cannot be applied for project and technology life cycle management purposes in industry at present.
Recommendation and Perspective. Following the outcomes of the case studies in the South African process industry, it is recommended that checklists and guidelines be used during project and technology life cycle management practices. Similar to the environmental dimension, it is envisaged that such checklists and guidelines would improve the availability of quantitative data in time, and would therefore make the SII procedure more practical in the future.
Keywords: Life Cycle Impact Assessment (LCIA); Life Cycle Management (LCM); process industry; Resource Impact Indicator (RII); Social Impact Indicator (SII); social sustainability Introduction The last decade of the twentieth century marked significant steps to draw the social dimension of sustainable development into the open . The inclusion of social aspects in the sustainability debate and practice has nevertheless been marginal compared to the attention given to the other two dimensions, especially from a business perspective [1,2,3].
However, stakeholders are forcing companies to address the inclusion of social sustainability by shifting pressure from environmental to social related concerns [4,5]. The social dimension is commonly recognised as the ‘weakest’ pillar of sustainable development due to a lack of analytical and theoretical underpinnings  and it is believed that the state of development of indicators or measurements for social business sustainability parallels that of environmental performances about 20 years ago .
Nevertheless, there is a definite need for practical tools to introduce social sustainability into business evaluation processes [1,7,8]. This paper proposes a methodology to assess the social sustainability of projects and technologies in the process industry by calculating social impact indicators, and addresses the following two questions: 1) What social criteria must such an assessment methodology consider and measure? 2) How must these criteria be addressed and measured?
To address the first question, a framework of social business sustainability criteria is defined, which is relevant for operational initiatives in the process industry. Social sustainable development indicators are then introduced, demonstrated and discussed, based on the defined framework.

The analysis showed that a comprehensive social sustainability framework should define appropriate criteria to address the company’s impacts on the social systems in which it operates, as well as the company’s relationship with its various stakeholders. A sustainable development framework for operational initiatives was subsequently developed and proposed, the social dimension of which is shown in Fig. 1. Table 2 provides the definitions of the criteria at the different levels of the framework, which are described in detail elsewhere . 1 1. 1 Social Sustainability Criteria Framework
Development of a framework for business management purposes in the process industry The current indicator frameworks that are available to measure overall business sustainability do not effectively address social aspects of sustainability at operational level in the process industry, especially in developing countries such as South Africa . The question arises what the exact scope of social sustainability should entail from a business management perspective.

The criterion addresses a business initiative’s impact on work opportunities within the company, the stability thereof as well as Employment Stability evaluating the fairness of compensation. Disciplinary and secrecy practices as well as employee contracts are addressed under this criterion. These are evaluated to Employment Practices ensure that it complies with the laws of the country, international human rights declarations as well as other human rights and fair employment practice standards. The criterion focuses on the health and safety of the workforce and evaluates preventive measures as well as the occurrence Health & Safety and handling of health and/or safety incidents. Capacity Development The criterion addresses two different, aspects namely research and development, and career development.
External Population focuses on the external impacts of the company’s operational initiatives on a society, e. g. impacts External Population on the availability of services, community cohesion, economic welfare, etc. Human Capital refers to an individual’s ability to work in order to generate an income and encompasses aspects such as health, Human Capital psychological wellbeing, education, training and skills levels. The criterion addresses Health and Education separately. Productive capital entails the assets and infrastructure an individual needs in order to maintain a productive life. The criterion Productive Capital measures the strain placed on these assets and infrastructure availability by the business initiative.
This criterion takes into account the effect of an operational initiative on the social and institutional relationships and networks of Community Capital trust, reciprocity and support as well as the typical characteristics of the community. Macro Social Performance focuses on the contribution of an organisation to the environmental and financial Macro Social Performance performance of a region or nation, e. g. contribution to exports. Socio-Economic Performance This criterion addresses the external economic impact of the company’s business initiatives. Economic welfare (contribution to GDP, taxes, etc. ) as well as trading opportunities (contribution to foreign currency savings, etc. ) are addressed separately.
Socio-Environmental This criterion considers the contributions of an operational initiative to the improvement of the environment for society on a Performance community, regional and national level. The extension of the environmental monitoring abilities of society, as well as the enhancement of legislation and the enforcement thereof, are included in this criterion. Stakeholder Participation focuses on the relationships between the company and ALL its stakeholders (internally and Stakeholder Participation externally) by assessing the standard of information sharing and the degree of stakeholder influence on decision-making. The quantity and quality of information shared with stakeholders are measured.
Information can either be shared openly with all Information Provisioning stakeholders (Collective Audience) or shared with targeted, specific groups of stakeholders (Selected Audience). The degree to which the company actually listens to the stakeholders’ opinion should also be evaluated. Two separate subStakeholder Influence criteria are included: Decision Influence Potential and Stakeholder Empowerment. Internal Human Resources 6 Int J LCA 11 (1) 2006 Social Sustainability Process Industry The conclusion was reached that no social aspect of the ten projects could be found that could not be classified into the criteria framework. In addition, all of the social criteria did not manifest in each asset life cycle phase. However, there may be social aspects that did not manifest in either the case studies or the framework.
Nevertheless, the basis on which the individual case studies were chosen makes these cases adequately representative of the current social environment in which construction, operation, and decommissioning occurs in the process industry. It is subsequently concluded that the framework is complete enough to be used as an initial basis to develop a social assessment methodology, which can incorporate social sustainability into project and technology management practices. The social sustainability framework was further validated by means of a Delphi Technique survey . The survey focused on the relevance of the proposed social criteria for the evaluation of projects or technologies and attempted to answer whether the project team, a functional unit within an organisation, or an organisation’s corporate governance framework should address the different social aspects.
A total of 23 project management experts in a process industry company in South Africa participated in the survey, which established the suitability of the social criteria, as well as the relevance of the criteria in terms of sustainable business practices. The outcomes of the survey support the conclusion reached by the case studies, but also suggest, according to the opinion of project management experts, that all the criteria are not relevant to project and technology management, but should rather manifest as part of corporate policy (Table 3) . 1. 2 Verification and validation of the completeness and relevance of the social criteria of the framework The social sustainability framework was verified by means of case studies testing the completeness and relevance of its criteria.
Since the aim of the framework is to assess the social sustainability of projects and technologies in the process industry, ten case studies were chosen that represent the three phases of the asset, or technology, life cycle with the greatest potential to cause social impacts, i. e. the Construction Phase, the Operation Phase, and the Decommissioning Phase. The rationale for focussing on the three asset life cycle phases, as well as the interaction between asset and project life cycles, can be found in literature . The case studies aimed to describe the significant social impacts that may occur during the life cycle phases in relation to the proposed framework, and to identify any social impacts that cannot be classified into the framework : • The construction of three process industry facilities: an incinerator, a mine, and a gas pipeline. The operation of four chemical manufacturing facilities, one in Germany, one in the USA, and two in different provinces in South Africa. • The decommissioning of three process industry facilities: a cyanide manufacturing plant, an acrylic fibre manufacturing plant, and a mine. Project related documentation, pertaining to each of the case studies, was evaluated and personal interviews were held with project responsible individuals . It must be noted that in case study research it is not easy to generalise results, since statistical analysis cannot necessarily be applied. Cases are not sampling units and cannot be treated as such. Table 3: Delphi Technique survey results

As a first approximation no characterisation factors are assumed and social LCI constituents are considered separately.
NC = Normalisation factor for the impact category based on the social objectives in the region of assessment, i. e. the inverse of the target state of the impact category. The information is obtained from social footprint data in the region of the assessment. And, Significance (or relative importance) of the impact category in a social group based on the distance-to-target method, i. e. current social state divided by the target social state (see section 1. 2). 2 Social Impact Indicator (SII) Calculation Procedure The main focus of this paper is the development and testing of a quantitative social sustainable development indicator calculation method.
A life cycle impact assessment (LCIA) approach has been proposed before for the evaluation of the social impacts of life cycle systems from compiled LCIs [13,14]. An introduced LCIA methodology developed specifically for the South African context, termed the Resource Impact Indicator (RII) approach , is thereby used as basis for the development of social indicators. The environmental RII approach considers the current and target ambient state or ecological footprint through a conventional distance-to-target normalisation and weighting calculation procedure . A similar calculation procedure is proposed for Social Impact Indicators (SII), using the four main social criteria (shown in Fig. 1) as Areas of Protection (AoP).
Three of these criteria represent the main groups of social resources on which the company can have an impact, while the fourth criterion represents all relationships between the company and stakeholders. The general SII calculation procedure is described through Eq. 1. (1) Where: SIIG = Social Impact Indicator calculated for a main social resource group through the summation of all impact pathways of all categorised social interventions of an evaluated life cycle system. QX = Quantifiable social intervention (X) of a life cycle system in a midpoint impact category C, i. e. project or technology specific information with regards to social impacts. Table 4: Midpoint categories and evaluation methods  Social Impact Indicators (SIIs) Internal Human Resources Midpoint category SC = CS = TS
To develop the calculation method, the same case studies used for the verification of the social criteria (see section 1. 2) were used to compile a list of possible social interventions, i. e. a social Life Cycle Inventory (LCI) of assessed operational initiatives in the process industry. However, the RII method makes use of mid-point categories. To define midpoint categories, the list of social interventions was mapped against the social criteria at various levels within the proposed social sustainability framework. A causal relationship diagram was consequently established for each of the four main social criteria, which define the midpoint categories. These causal diagrams are shown in the Appendix .
Three measurement methods are proposed to express the defined midpoint categories in equivalence units (Table 4) : • Established risk assessment approaches, which require a subjective evaluation of the probability of occurrence, the projected frequency of the occurrence, and the potential intensity thereof; Measurement methods to establish equivalence units Quantitative Risk Quantitative Quantitative Risk Qualitative Quantitative Qualitative Quantitative Quantitative Quantitative Quantitative Quantitative Quantitative Quantitative Quantitative Quantitative Qualitative Quantitative Qualitative/Quantitative Quantitative External Population Stakeholder Participation Macro-Social Performance

The defined midpoint categories, which, from the validation survey (see section 1. 2), are considered appropriate at project or technology management level, together with pro- posed units of equivalence for evaluation purposes are shown in Table 5. The units of equivalence were determined from the characteristics of the social interventions identified from the ten case studies.
The definitions of the midpoint categories make it evident that the normalisation and significance steps will be constrained by what is practicably measurable within a society where an operational initiative, i. e. project or technology (from an industry perspective), will typically occur. The availability of information is likely to differ be- Int J LCA 11 (1) 2006 9 Process Industry tween developed and developing countries. Furthermore, the projection of the social interventions of a project or technology may be problematic or at least differ from case to case. Separate studies may be required for some of the social sustainability criteria, e. g. stakeholder participation, even at project-specific level, which may be problematic. Case Studies to Demonstrate and Test the SII Calculation Method Social Sustainability 3. 1 Construction of an open cast mine 3. 1. 1 Background The SII calculation method was applied to three case studies to determine the current feasibility thereof in terms of data availability. In the third case study, environmental Resource Impact Indicators were also calculated using the RII method . All case studies are set in South Africa and project information was obtained from Environmental Impact Assessment (EIA) studies as well as interviews with members of the respective project teams. Due to the hindsight application of the SII method no additional data could be collected from a project perspective.
Social footprint information was obtained from: • Statistics South Africa ; • South African Department of Transport ; • South African Council for Scientific and Industrial Research (CSIR) ; • South African Department of Health ; • South African Department of Labour ; • NOSA International ; and • Municipal Demarcation Board South Africa  and individual municipalities, e. g. some municipalities have undertaken Strategic Environmental Assessments (SEAs) in certain regions of South Africa. In the case studies, mid-point categories were evaluated in respect of whether both project and social footprint information are available, and if the respective information is comparable. It is noted that whereas LCA normally considers a product’s life cycle, these case studies focus on the asset, or technology, life cycle (as described in section 1. 2) with the functional unit being one operational year of the asset.
However, since the asset life cycle and the associate product life cycle interact through the asset’s operational phase , the indicators could be translated to a typical product-manufactured functional unit. In 1996 a petrochemical company in South Africa announced its intention to develop an Open Cast Strip Mine on the banks of the Vaal River between the Gauteng and Free State Provinces. The project was motivated on the basis that the reserves of the company’s main mine in the area had reached the end of its economic life and that this posed a threat to the future of a large chemical manufacturer in a nearby town, which was supplied by the mine from 1952.
Ultimately, a threat to the existence of the chemical manufacturer is a direct threat to the existence of the town and in a sense the province since the manufacturer contributes 12% to the geographical economy of the region. The project was met with a lot of resistance from the public, especially owners of riverside properties. The project was stopped after a non-governmental organisation took the company to court and won a legal battle, which changed the mining legislation of South Africa. 3. 1. 2 Available project and social footprint information Tables 6 and 7 summarise the available project information and social footprint information that have been obtained from the Environmental Management Programme Report  and the specialist study on the macro social economic impacts . 3. 1. 3 SIIs for the project
The information presented in Tables 6 and 7 highlights the mismatch between available project and social footprint information. SIIs were calculated as far as possible where both appropriate project and social footprint information was available for midpoint categories (Table 8) using Eq. 1. The project will have an overall positive social impact, although job creation could not outweigh the negative impact on the comfort level on the neighbourhoods in a close vicinity to the plant. The overall positive impact is mainly due to the large contribution the project will make to the Gross Geographic Product (GGP) of a relative small area, which relies strongly on mining.

The biggest social impact is the impact on comfort level due to atmospheric emissions, i. e. secondary environmental impacts. 3. 3 Decommissioning of a fibre manufacturing plant Process Industry In addition, environmental RIIs were calculated using standard RII values, which were calculated for selected process parameters . Table 11 shows the available project and social footprint information. 3. 3. 3 Environmental and social impact indicators 3. 3. 1 Background Tables 12 and 13 show the calculated Social and Environmental Impact Indicators.
The values in Tables 12 and 13 show that although a similar methodology was followed to calculate SIIs compared to RIIs, the indicator outcomes are vastly different. This highlights that the interpretation of indicators remains challenging. Assessing the overall sustainability performance of a project or technology by allowing trade-offs between the contributions and damages should be seriously considered before it is applied. Ultimately, the trade-offs between the different dimensions would be the responsibility of the specific decision-makers, and therefore reflect the preferences of the decision-makers. 3. 4 Conclusions from the case studies In the early 1990s a second-hand acrylic fibre plant from a manufacturing facility in France was dismantled and relocated in the KwaZulu Province of South Africa.
However, the decreasing acrylic fibre market in South Africa, combined with a lack of import protection, led to the decision to decommission the plant in March 2002. The plant manufactured its last products in May 2002, which were sold in August 2002. The plant was dismantled and the site rehabilitated by March 2003. 3. 3. 2 Available project and social footprint information Using the company’s sustainable development report, the Strategic Environmental Assessment (SEA) of the region, as well as the sustainable development indicator data of the municipal area in which the plant operated, the SII calculation procedure was applied to calculate the social impacts. As stated before it is not easy to generalise from case study research.
However, the case studies showed that it is not possible to calculate all social midpoint category indicators, Table 11: Available project and social footprint information for the region of the fibres plant Interventiona Nature of Jobs Project Information 250 employment opportunities lost (5% relocated = 12 ) Social Footprint Information eThekwini unemployment: 591,024 eThekwini employment: 782,933 Target: To have everyone employed excluding people who prefer to be not economically active.

In addition, the units of equivalence cannot be fixed since they depend on the available information. This complicates indicator comparisons between various projects. The limitation of available social footprint information results in the fact that only some midpoint category indicators are possible, i. e. permanent positions, water usage, energy usage, nature of sales, and comfort level, which leads to an impaired social picture.
In addition, the midpoint category indicators for water usage, energy usage and comfort level are much higher than permanent positions, thus resulting in a net negative social impact for any proposed development, which may not be a representation of the true social influence of the project or technology. 4 Conclusions and Recommendations sions of sustainable development . The research therefore concludes that a quantitative social impact assessment method cannot be applied for project and technology life cycle management purposes in industry at present. It is emphasised that these conclusions were reached from a process LCA perspective, which is industry sector-wide.
Research with a product LCA focus may lead to different outcomes. Although a comprehensive top-down approach was followed, a bottom-up approach may be more appropriate for product LCAs , as the selection of suitable criteria would be constrained to the specific scope of a LCA study. 4. 1 Further steps to quantify social impact indicators A case study independent analysis of available social footprint information in South Africa confirmed the main finding of this paper that social footprint information is not available for all midpoint categories . It is regarded as an international problem that current available statistics are incapable of providing an integrated view of various dimen-
It is proposed that social sustainability should be incorporated into project and technology life cycle management by means of guidelines and checklists. Similar to the environmental dimension, it is envisaged that such checklists and guidelines would improve the availability of quantitative data in time, and would therefore make the SII procedure more practical in the future. Although such guidelines and checklists have been developed from a theoretical perspective , practical guidelines and checklists from a project or technology life cycle management perspective are yet to be dem- 14 Int J LCA 11 (1) 2006 Social Sustainability onstrated. Further cases are subsequently required for demonstration and analysis purposes.
While the guidelines and checklists may lead to a paradigm shift in industry towards obtaining and evaluating social impact-related information, it is also suggested that a lesscomprehensive list of social criteria is used as a starting point to develop social LCA-specific methodologies, possibly using those midpoint category indicators that were quantifiable in the case studies of this research, i. e. permanent positions, water usage, energy usage, nature of sales, and comfort level, or other midpoint categories that are currently proposed . However, social issues are highly influenced by cultural perceptions, and it would be best to undertake such a task at national level.
National indicator sets can then be compared and combined on an international level. In addition, it is suggested that the development of data quality standards are required for social criteria, similar to the efforts of SETAC and ISO for the environmental criteria used in LCA today. Such standards would greatly improve the transparency of calculated indicators. References  Zadek S (1999): Stalking Sustainability.
