What is sustainable supply chain management and certification?

The goal of sustainable supply chain management is to reduce, eliminate and manage the impacts and risks of production at their place of origin and across the supply chain (both upstream and downstream). In particular social and environmental criteria need to be fulfilled, as well as company competitiveness maintained [1]. Social responsibility — e.g. as mandated in Germany by the Supply Chain Act, which aims to ensure that human rights are respected—is a major objective, as well as increasing transparency. For example, businesses report on environmental performance within a variety of reporting schemes (e.g. EMAS [3] and ISO 14001 [4]), and multiple guides and tools are available for strengthening company performance [5]. The figure below depicts seven process steps of sustainable supply chain management [6]

What is certification?

Certification and standards provide customers with information on whether the production of a product has met specific norms related to social, environmental and/or economic criteria, in particular at the beginning of the supply chain. In addition, companies use certification to manage and minimize risks in the supply chain and to maintain their license to operate. Certification and standards are typically adopted voluntarily and combined with compliance verification [7], traceability systems [8], and labels to distinguish products in the marketplace. They may be applied in a business-to-business context (e.g. Global G.A.P. [9]) or directed at the final consumer (e.g. Fairtrade [10]) or both (e.g. ISCC PLUS [11]). Certification schemes also increasingly play a role in regulated markets where they are used to independently verify compliance with sustainability requirements. Examples include the Renewable Energy Directive (RED) under which the European Commission has recognized certification schemes [12] or CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation), a system established by ICAO (International Civil Aviation Organization, a UN Agency [13]. There has been a proliferation of environmental standards (see e.g. the Standards map) and labels (see e.g. the Ecolabel Index) linked to varying degrees of strength [14] (which can be evaluated by consumers on e.g. Label online).

How are supply chain management and certification used to contribute to a sustainable bioeconomy?

Around one-quarter to half of the environmental impacts from consumption are felt in regions other than where that consumption occurs [15]. For instance, 30% of global species threats [16] and 32% of the consumption of scarce water [17] have been linked with international trade. Between 2005 and 2013 more than 60% of forest loss could be attributed to the expanding area of commercial cropland, pastures and tree plantations, in particular for cattle meat, forestry products, oil palm, cereals and soybeans [18]. Preventing global forest loss, connected to the biodiversity and climate crises, is one of the core challenges of implementing a sustainable bioeconomy. To this end, restrictions on “land use change” are starting to be incorporated into standards, norms and legislation [19] in a more stringent way [20]. This is one manner in which reporting and certification have an essential role to play to ensure that the bioeconomy is supplied by sustainably-produced biomass.

Overall, they act to connect (link through monitoring and awareness raising) and help prevent (through the establishment of best practice norms) the impacts of local production abroad. Some environmental and social impacts are well established elements of reporting and certification (e.g. banning child labour and avoiding toxic substances) whereas others are more in their infancy (e.g. biodiversity—see the Biodiversity in Good Company Initiative) [21].

What are the limitations?

The basic limitation of product chain-based measures is that a growing demand for products which may be locally produced in a sustainable fashion may result in unsustainable effects at larger scales. One prominent example is the indirect land use change induced by a growing use of 1st generation biofuels, which cannot be solved even by the updated certification criteria required by the EU Commission (RED II). If, theoretically, all agriculture would work organically worldwide, the criteria of local sustainability would be fullfilled, however, the global agricultural area would need to expand to compensate for up to one-third lower yields [22], leading to biodiversity losses etc., if no countermeasures such as changed dietary patterns and/or reduced food loss generation would be applied.

Limitations and challenges related to certification

There is currently a spatial scale mismatch between a) the farm, farm cluster or plantation that is certified and b) the scale at which desired benefits are delivered [23]. This can limit benefits at a landscape scale (e.g. biological connectivity, watershed functions, and other ecosystem services) and may lead to ineffectiveness to e.g. combat deforestation at the scale needed. That said, the current collection of studies covering the effectiveness of sustainability certification is scarce and existing studies point in different directions [24]. Moreover, investments and activities to mitigate risks and improve stringency, quality and effectiveness are widespread. Those risks include loopholes and corruption (e.g. using subsidiary companies and partial certification). Some have also pointed to a risk of “washing down” in some cases [25] – e.g. decreasing stringency in order to raise market uptake for certification. Among customers a growing body of labels could also lead to difficulty to distinguish between them, which carries the risk of a loss of faith in the standards process by customers (e.g. accusations of greenwashing), but which other studies also dispute [26]. Progress in the opposite direction is also clearly visible. For example, some certification schemes are already working on the integration of landscape/jurisdictional approaches [27], on the use of remote sensing data [28] on improving biodiversity at a landscape level [29], and on setting minimum standards. Recommendations and possibilities are promising (e.g. for the food sector see the Business & Biodiversity campaign).

However, there are also some inherent gaps from a monitoring perspective linked to the nature and purpose of certification, which is why a bundle of approaches is so important. For example, standards focus on production practices, but do not measure the outputs or impacts of changed practices on the environment. Auditors can and should be trained to incorporate aspects related to biodiversity into verification systems (like ‘potential for biodiversity created’ [21]), but additional monitoring is needed to understand the greater system-wide impacts of change (at ecosystem, landscape, ecoregion and biosphere levels). This is why complementary action is needed—in terms of monitoring and regulation (both in the countries of origin and consuming countries — see Footprints).

Many of the same issues also limit sustainable supply chain management and reporting, especially in terms of effectiveness — at least currently. For example, reporting is often focused on providing transparency and applying best practices, but not on the detailed measurement and monitoring of impacts across scales. Biodiversity has also been — up to now —widely neglected and/or vague in accountability and reporting schemes [30]. However, social and environmental certification schemes have started their own regular impact assessments, based to a large extent on ISEAL’s Code of Good Practice [31], which is also leading to improvements of the systems [2]. In addition, a multitude of efforts are underway to close this gap, also driven by the interests of companies themselves to be agents of change (see e.g. the EU Business @ Biodiversity Platform). The need and potentials to ensure a safe, secure and sustainable supply of biomass for the bioeconomy are both pressing and vast, and depends on how quickly and comprehensively businesses are willing to invest in ensuring that their supply chains are, indeed, sustainable.
