Assessing the potential additionality of certification by the round table on responsible soybeans and the roundtable on sustainable palm oil
Open accessAbstract
Multi-stakeholder roundtables offering certification programs are promising voluntary governance mechanisms to address sustainability issues associated with international agricultural supply chains. Yet, little is known about whether roundtable certifications confer additionality, the benefits of certification beyond what would be expected from policies and practices currently in place. Here, we examine the potential additionality of the Round table on Responsible Soybeans (RTRS) and the Roundtable on Sustainable Palm Oil (RSPO) in mitigating conversion of native vegetation to cropland. We develop a metric of additionality based on business as usual land cover change dynamics and roundtable standard stringency relative to existing policies. We apply this metric to all countries with RTRS ( n = 8) and RSPO ( n = 12) certified production in 2013–2014, as well as countries that have no certified production but are among the top ten global producers in terms of soy ( n = 2) and oil palm ( n = 2). We find RSPO and RTRS both have substantially higher levels of stringency than existing national policies except in Brazil and Uruguay. In regions where these certification standards are adopted, the mean estimated rate of tree cover conversion to the target crop is similar for both standards. RTRS has higher mean relative stringency than the RSPO, yet RSPO countries have slightly higher enforcement levels. Therefore, mean potential additionality of RTRS and RSPO is similar across regions. Notably, countries with the highest levels of additionality have some adoption. However, with extremely low adoption rates (0.41% of 2014 global harvested area), RTRS likely has lower impact than RSPO (14%). Like most certification programs, neither roundtable is effectively targeting smallholder producers. To improve natural ecosystem protection, roundtables could target adoption to regions with low levels of environmental governance and high rates of forest-to-cropland conversion.

Transparency does not always lead to the desired positive outcomes and may lead to reverse impacts.
“Transparency does not always lead to the desired positive outcomes and may lead to reverse impacts (Mol, 2010;Garrett et al., 2016;Gardner et al., 2018;van der Ven et al., 2018).”

The Introduction describes roundtables as transparent but says industry participation may reduce the stringency of their standards. The Limitations section also says certification may have reduced benefits through displacement effects. These passages support the caution that transparency does not guarantee positive outcomes, but they do not say transparency itself causes reverse impacts. (LLM, conf=0.76)
Experimental — accuracy not yet measuredCivil society pressure to abandon unsustainable practices may lead buyers to change suppliers but not to address the core problem, creating leakage of unsustainable operations elsewhere.
“In the case of leakage, civil society pressure to abandon unsustainable practices may for example lead buyers to change suppliers but not to address the core problem.This creates the so-called effect of leakage of unsustainable operations to be carried on somewhere else (Henders and Ostwald, 2014;Garrett et al., 2016;Gibbs et al., 2016;Alix-Garcia and Gibbs, 2017).”
From Making deforestation risk visible. Discourses on bovine leather supply chain in Brazil (2020) · cites this paper as Garrett et al., 2016
Section 6.1 (page unavailable) says environmental groups pressure oilseed traders to eliminate deforestation from supply chains and that soy traders can reduce reputational risk by sourcing more soy from temperate regions. It does not say that unsustainable production consequently continues elsewhere or identify this supplier shift as leakage. (LLM, conf=0.83)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
