Social LCA in the European Union, a tool to measure the social impacts of technology implementation (27 November 2020)

Since the publication of the Social Lifecycle Assessment (LCA) Guidelines in 2009, the methodology has been steadily improved and refined. With a new update of the Guidelines around the corner (publication expected 2021), NEMO thought the time ripe to discuss current practices and challenges in social LCA. More than 30 participants from academia, research, business and government participated in the webinar.

Andrea di Maria (KU Leuven) and Alberto Vázquez Ruiz (CATAPA) started the workshop with a short introduction on the sustainability assessment approach in NEMO. They highlighted some challenges of Social LCA, such as limited access to company data compared to environmental LCA, quantification of social aspects and a proper visualization of the results.

Claudia di Noi (Greendelta) presented the Neves Corvo case in Portugal, which was studied in the ITERAMS project. After a social hotspot screening revealed that the perception of social issues might be as important as the identified social impacts themselves, a new methodology was developed to compare the identified with the perceived social impact. Technical impacts, whether positive or negative, are not always perceived, which shows the importance of a good communication policy. At the end of her talk, Claudia challenged the audience by asking “does a quantitative approach make sense for social aspects?” and stating that while S-LCA may give an important contribution, it should be complemented by other social assessment approaches.

In the IMPACT project, S-LCA was applied to small-scale mining in Bosnia and Herzegovina. Stéphanie Muller (BRGM) explained how the type I S-LCA hot spot analysis identified the most vulnerable spots for SOSO (Switch-on Switch-off) mining in Europe, and led to some recommendations for mitigation measures to be included in a future business plan. Stéphanie also invited the participants to reflect on open issues such as the impact of scale (is there an upscaling effect?), data representativeness and how to combine different kinds of social assessments. From the audience, Olga Sidorenko reflected that SLO studies have demonstrated the importance of scale, because this is directly linked to the potential impact.

In the third and last case study, Lucia Mancini (JRC) showed how S-LCA was used to assess the social impact of Responsible Sourcing initiatives in cobalt artisanal mining in the DRC. The assessment detected that price and fairness are important aspects for local stakeholders, and measuring such positive impacts is crucial. The study also noted distinct gaps in the S-LCA databases (e.g. on land competition and demography) which should be solved.

While the case studies highlighted that there are still a lot of questions to solve within the S-LCA methodology itself, Andrea di Maria (KU Leuven) added another level of complexity by asking “how do we integrate the S-LCA with other assessments such as E-LCA (environmental) and LCC (economic)”? One of the key questions is “to aggregate or not to aggregate” the results – while aggregation can be useful to simplify and draw conclusions, it inevitably entails a loss of information and detail.

In the ensuing debate, Lucia Mancini argued to treat social aspects differently than other assessments, because aggregation is very difficult to achieve in practice, and can only be done for certain aspects. Claudia di Noi remarked that results can be grouped in topics instead of impact categories, to combine different dimensions. Alberto Vázquez Ruiz (CATAPA) added that comparison can only be considered when the research question is the same for all assessments, which is rarely the case, the intentions of the researchers should be clearly stated, and the chosen indicators justified.

Bernard Mazijn (researcher and policy advisor) remarked that while policy has a preference for aggregation and easy visual information (e.g. colour coded dashboard), a researcher prefers to keep the highest possible level of information. Interdisciplinary collaboration, e.g. with mathematicians in PCA analysis, could contribute to solve the problem.

Alberto Vázquez Ruiz stressed that Social LCA – a scientific tool to measure impacts – differs from Social License to Operate (SLO) – an ongoing process in which a company works to ensure the social acceptance of its operations locally. Therefore, performing a S-LCA shouldn’t be used as a means to imply that the company has obtained the SLO.

Other questions focused on the S-LCA methodology itself. Data reliability remains an issue, although the guidelines give some support with quite rigorous standards. In addition, quantification is a major concern in different ways: which indicators to use, and how to ensure that the information available in qualitative information is not lost (e.g. not only the number of jobs counts, but also the quality of them).

S-LCA was developed by people with a strong background in E-LCA, who are mostly researchers and engineers but not social scientists. As such, they are often not trained in interviewing, and neglect the influence a researcher can have on the object of their study. The debate ended with a clear request to include more social scientists in the S-LCA, as they can give valuable insight into these matters.

In his concluding speech, Bernard Mazijn (Head of the Cabinet Ministry of Climate, Environment, Sustainable Development and Green Deal) drew attention to the fact that social aspects go further than the European Union. Mining for virgin materials is downsized in Europe because it is much cheaper to obtain these materials from countries with less stringent (environmental and human rights) legislation. If we want a truly sustainable regional development, we need to go beyond the European to the global level in order to find a way to protect the rights of the workers and their communities abroad who may be suffering from our economic activities. Bernard also emphasized the strong political engagement and activism of early S-LCA researchers, and the support that policy can give to help them deliver results. He invited the audience to gather support among local ministers and MPs to strengthen the need for S-LCA.

In conclusion, the SLCA workshop raised a number of questions for further debate. As a first step, NEMO invited participants to contribute to a joint paper on multicriteria assessment. Interested parties are requested to contact andrea.dimaria@kuleuven.be.

Andrea di Maria (KU Leuven)

Andrea Di Maria is a post-doctoral researcher at the department of materials engineering, at KU Leuven. He obtained a PhD in 2018 at KU Leuven, with a thesis focusing on the future challenges to combine circular economy and life cycle thinking approached in the construction sector. Since September 2018, Andrea works as a post-doctoral researcher at KU Leuven on various EU-H2020 and EIT-raw materials projects, on near-zero-waste strategies for the mining and metals sectors. Andrea’s current research interests focus on the environmental evaluation of new materials from residues, and on the integration of environmental, economic and social analysis to promote circular economy.
