Abstract

On 26 May 2021, the District Court of The Hague (The Netherlands) passed an innovative judgment in Milieudefensie v. Royal Dutch Shell. The Court interpreted Shell's duty of care towards the inhabitants of the Netherlands as requiring it to mitigate climate change by reducing the carbon dioxide emissions resulting from its global operations by at least 45% by 2030, compared with 2019. This case comment salutes the identification of a corporate duty of care for climate change mitigation but expresses scepticism regarding the Court's interpretation of this duty. The Court's reading of global climate mitigation objectives and climate science, which form the basis of its determination of Shell's requisite level of mitigation action, is plagued with inconsistencies. It is argued here that, in order to determine the standard of care applicable to Shell, the Court should have relied not only on a ‘descending’ reasoning as to what ought to be done, but also on an ‘ascending’ reasoning accounting for industry practices.

1. INTRODUCTION

The judgment of 26 May 2021 of the District Court of The Hague (The Netherlands) in Milieudefensie v. Royal Dutch Shell recognized an obligation on the part of Royal Dutch Shell (Shell) to mitigate climate change. In the application of this obligation, Shell was ordered to reduce all carbon dioxide (CO2) emissions resulting from its global operations – including those from the combustion of the oil-and-gas products it supplies to customers – by 45% by 2030, compared with 2019.Footnote 1 This is the first time that a court has imposed such a broad mitigation obligation on a corporation. It is also one of the first occasions on which tort law has successfully been invoked in litigation on climate change mitigation.Footnote 2 The District Court declared the judgment to be provisionally enforceable,Footnote 3 even though Shell has (unsurprisingly) indicated its intention to appeal.Footnote 4 The judgment is likely to have an impact on ongoing litigation against various oil-and-gas and public utility corporations in the Netherlands and elsewhere.Footnote 5

This case comment presents a critical perspective on the judgment. It salutes the recognition of a corporate duty of care for climate change mitigation, but it also expresses scepticism regarding the Court's interpretation of this duty. As a result of several inconsistencies in its reasoning, the District Court fails to justify Shell's requisite level of mitigation action in any coherent manner. In particular, the Court relies on the doubtful assumption that Shell's requisite level of mitigation action can be directly inferred from global mitigation objectives and climate science, in isolation from more empirical considerations. The comment concludes that the District Court should have considered not only these global objectives, but also the practice of other companies involved in the same sector, to determine what Shell can realistically be expected to do with regard to climate change mitigation.

Section 2 provides an overview of relevant procedural aspects of the case. Section 3 notes the identification of Shell's duty of care for climate change mitigation under Dutch law. Section 4 reveals four major inconsistencies in the Court's interpretation of this mitigation duty as requiring Shell to achieve a specified mitigation outcome. Section 5 outlines an alternative judicial methodology to interpret a company's climate mitigation duty. Section 6 concludes.

2. PROCEDURAL ASPECTS

The case was brought by seven non-governmental organizations (NGOs) and 17,379 individuals against Shell – the parent holding company of a complex international network of subsidiaries producing and distributing oil and gas around the world – based on the climate impacts of the group's global operations. The respondent did not challenge the District Court's jurisdiction, which the claimants justified as based alternatively on Shell's domicile (its headquarters are situated in The Hague) or the place where the events causing the tort (the adoption of the group's strategies) took place.Footnote 6 The respondent also did not question, as a matter of principle, that a parent company can owe a duty of care for the overseas operations of its subsidiaries. This principle had been recognized in a number of previous cases, including one involving some of the same parties, decided by the Court of Appeal of The Hague just a few months earlier.Footnote 7

Shell raised two preliminary questions regarding the standing of the plaintiffs and the applicability of Dutch law. Regarding the former, the Court admitted a class action by six of the NGO plaintiffs, representing the interests of Dutch residents and residents of the Wadden Sea area, which straddles the German border.Footnote 8 It did not give standing to the seventh NGO (Action Aid), which sought to represent the interests of foreign populations. The Court considered that this would bundle dissimilar interests, alluding to ‘huge differences in the time and manner in which the global population at various locations will be affected by global warming’.Footnote 9

The factual bases for this finding are questionable as no scientific evidence was provided for distinguishing between the impacts of climate change occurring within the Netherlands and those taking place elsewhere, at least some of which are prima facie very similar.Footnote 10 Nevertheless, having made this finding, the Court should have reflected it in its substantive discussion about the need to mitigate climate change. Determining the requisite level of action on climate change mitigation inevitably involves, one way or another, a balance between the costs of mitigation action and its benefits (that is, the avoidance of additional climate impacts, or the reduction in the risks thereof).Footnote 11 The case for reducing Shell's global CO2 emissions would have been much stronger if the Court had considered the global benefits of doing so, rather than including only the benefits accruing within the territory of the Netherlands.

The Court refused standing to the individual plaintiffs on the ground that they lacked ‘a sufficiently concrete individual interest’.Footnote 12 This is in line with recent decisions in several other jurisdictions where standing to invoke mitigation obligations has been awarded to parties representing public interests but not to those wanting to vindicate individual rights.Footnote 13 These decisions appear justified in the light of the fact that the impacts of climate change, albeit significant, are diffuse, and it may not be possible to identify individual ‘victims’ of climate change, or individuals with a sufficiently distinct risk of becoming victims.

To justify the application of Dutch law, the Court relied on Article 7 of the European Union (EU) Regulation (EC) No. 864/2007 on the Law Applicable to Non-contractual Obligations (Rome II Regulation),Footnote 14 lex loci commissi delicti: the Netherlands is ‘the country in which the event giving rise to the [environmental] damage occurred’, in so far as the group's worldwide CO2 emissions can be traced to strategic decisions made at its headquarters in the Netherlands.Footnote 15 As the Court acknowledged, this interpretation of the Rome II Regulation implies that more than one event could give rise to the same environmental damageFootnote 16 and, thus, that more than one law could be applicable as lex loci commissi delicti. By allowing plaintiffs to select the law most favourable to their case, this construction of the Rome II Regulation subjects corporations to greater risks of litigation for the environmental harm caused in the course of their international operations.

3. A CORPORATE DUTY OF CARE FOR CLIMATE MITIGATION

The most innovative aspect of the judgment regards its interpretation of the Dutch law on torts as requiring the defendant to take climate change mitigation action. The relevance of tort law to climate change mitigation has long been discussed in academic circles, but few cases have actually been brought before the courts on this basis,Footnote 17 and even fewer have overcome procedural challenges and led to favourable substantive decisions.Footnote 18 One of these exceptions is the case of Urgenda v. The Netherlands, where the same District Court (with different judges) found that the State of the Netherlands had an obligation to reduce its greenhouse gas (GHG) emissions by 25% by 2020, compared with 1990.Footnote 19 In retrospect, the Urgenda case was relatively low-hanging fruit: states certainly have an obligation to mitigate climate change as parens patriae – obviously so under climate treaties,Footnote 20 and arguably also under customary law,Footnote 21 and perhaps then also under tort law or (as the Supreme Court found in Urgenda) human rights treaties.Footnote 22 To make the same argument stick with regard to private companies operating in a competitive environment is more difficult, even in the case of a multi-national oil-and-gas company to which slightly over 2% of global historical CO2 emissions can be attributed.Footnote 23

The Court noted that Shell's mitigation duty ‘ensues from’ Article 6:162 of the Burgerlijk Wetboek (BW) (Dutch Civil Code).Footnote 24 This provision defines tortious acts as including acts and omissions ‘in violation of … what according to unwritten law has to be regarded as proper social conduct’.Footnote 25 Accordingly, the Court considered that Shell ‘must observe the due care exercised in society’, to be interpreted in the light of ‘all circumstances of the case’.Footnote 26

Despite the brevity of the Court's explanation, this part of the judgment is convincing. Shell's defence was based largely on the lack of a direct causal link between the action of the parent company and the resulting climate impacts.Footnote 27 Yet, strategic decisions that outline the global operations of a major oil-and-gas corporation have a sufficiently foreseeable impact on global CO2 emissions, and thus on the diffuse harm that climate change causes to ecosystems and societies, to justify the existence of a duty of care.Footnote 28 The need for oil-and-gas companies to reduce emissions is not only implied by science and international objectives, but also acknowledged by these very companies, most of which have adopted and implemented relevant policies.Footnote 29 Shell itself had already defined a mitigation objective (reducing its net carbon footprint by 30% by 2035, compared with 2016) and taken some measures to achieve it (such as by reducing flaring, venting, and fugitive emissions, and by investing in low-carbon energy and carbon sinks).Footnote 30

The key question of the case, therefore, was not so much the existence of a duty of care for climate change mitigation, but rather its content. A company would certainly be in breach of its duty of care if, acting in isolation from other companies, it was single-handedly responsible for GHG emissions causing dangerous interference with the climate system. Yet, even a large oil-and-gas corporation like Shell is responsible (directly or indirectly) only for a limited share of global GHG emissions,Footnote 31 and it is part of a global economy that relies heavily on fossil fuels. Determining the content of the duty of care of such a corporation – the level of GHG emissions that would be allowed without breaching this duty of care – is a challenging task. As the following shows, this part of the judgment is plagued by inconsistencies, which originate from the Court's questionable assumption that Shell's requisite level of mitigation action can be inferred from global mitigation objectives and climate science.

4. THE JUDICIAL ASSESSMENT OF SHELL'S REQUISITE MITIGATION ACTIONS

The Court sought to determine what would constitute Shell's ‘proper social conduct’ with regard to climate change mitigation by reference to several ‘circumstances’.Footnote 32 In particular, the Court referred to ‘widely accepted soft law instruments’,Footnote 33 such as the United Nations (UN) Guiding Principles on Business and Human Rights,Footnote 34 to suggest that human rights treaties could be relevant in assessing Shell's duty of care.Footnote 35 This aspect of the judgment has attracted considerable attention.Footnote 36 Yet, even if one accepts that human rights treaties can be interpreted as having such horizontal effects on corporations,Footnote 37 these treaties do not contain any specific standards that can help to determine the requisite level of mitigation action of any particular actor. This is true with regard to states,Footnote 38 and even more so for corporations. Thus, the reference to human rights treaties is purely ornamental; it cannot help the Court to determine the content of Shell's mitigation duty. Nor is the reference to human rights helpful in determining the existence of a duty of care;Footnote 39 the fact that CO2 emissions cause illicit harm can be justified without reference to human rights law.

The decisive factor in the Court's determination of Shell's mitigation duty is the global objective of limiting global warming to 1.5 or 2°C above pre-industrial levels.Footnote 40 However, as the following will show, it is only as the result of four consecutive mischaracterizations and misconstructions of this objective that the Court could interpret this objective as requiring Shell to reduce its CO2 emissions by 45% by 2030, compared with 2019.Footnote 41

Firstly, the Court suggested that the temperature targets ‘are derived from’ reports of the Intergovernmental Panel on Climate Change (IPCC).Footnote 42 Yet, while these targets are vaguely informed by science, they result essentially from political agreements.Footnote 43 The scientific method cannot make the value judgments necessary to determine the right balance between the costs and benefits of mitigation;Footnote 44 as such, the IPCC is precluded from making any such policy recommendations.Footnote 45 Having mischaracterized the origin and nature of the temperature targets, the Court envisioned them as something that must be achieved as a matter of scientific necessity, when they are merely a political objective that states endeavour to achieve through cooperation.Footnote 46

Secondly, the Court largely ignored the relative indeterminacy of the temperature targets (for example, 1.5 or 2°C?)Footnote 47 when suggesting that they could be used to determine Shell's requisite mitigation action. The Court selected an IPCC mitigation pathway that assumes a 45% reduction in global CO2 emissions by 2030, compared with 2010.Footnote 48 As the Court notes, this projection would ‘yield a 50% chance of limiting global warming to 1.5°C and an 85% chance of limiting global warming to 2°C’.Footnote 49 Yet, the Court does not justify its selection of this pathway over any other pathway consistent with a plausible interpretation of the temperature targets. For instance, another IPCC pathway, associated with a 66% chance of achieving the 2°C target, assumes only a 25% reduction in global CO2 emissions by 2030, compared with 2010.Footnote 50

Thirdly, the Court implicitly assumes that Shell must reduce emissions from its global operations at the same pace as global CO2 emissions are projected to decrease.Footnote 51 Yet, emissions reductions inevitably unfold differently in various segments of the global economy. For instance, the largest share of mitigation outcomes from 2010 to 2030 is expected to result from massive cuts in coal consumption, while natural gas could continue to be used widely as a substitute for more CO2-intensive fuels.Footnote 52 A projection developed by the International Energy Agency (IEA), using assumptions consistent with the 1.5°C pathway selected by the Court, suggests that overall CO2 emissions from the combustion of oil and gas will only decrease by 19% from 2010 to 2030 (30% for oil, 1% for gas), compared with a 57% reduction for coal.Footnote 53 Shell may have more presence in some segments of the global oil-and-gas market than in others: it may, for instance, produce more oil, or more gas, than the average oil-and-gas corporation, or sell it in countries or sectors where consumption would be expected to decrease more quickly, or more slowly, than the global average. As such, it cannot simply be assumed that Shell's emissions reduction trajectory will follow the sectoral average suggested by the IEA, any more than it can be expected to follow the global emissions reduction trajectory outlined by the IPCC. Overall, any such projection is necessarily based on questionable equity assumptions on the distribution of the costs of mitigation action. The IPCC and the IEA scenarios seek to define a least-cost way of achieving a certain mitigation outcome, but this would not necessarily result in a justifiable allocation of the costs of mitigation action within societies and among countries and generations.

Fourthly, having interpreted the duty of care as requiring a 45% emissions reduction by 2030 on a 2010 baseline, the Court decided, for obscure reasons, that the baseline for Shell should be 2019 rather than 2010.Footnote 54 Milieudefensie had initially referred to a 2010 baseline in its Summons, but it subsequently amended its claims to suggest a 2019 baseline, on the ground that 2019 was the most recent year for which Shell had reported its CO2 emissions data.Footnote 55 Yet, the fact that 2019 data is available does not mean that it is relevant in assessing Shell's duty of care. As Shell's emissions increased during the 2010s, a 2019 baseline allows the company to emit more by 2030 than if a 2010 baseline had been used. It is unclear how the Court came to the conclusion that a 2019 baseline ‘sufficiently corresponds with the widely endorsed consensus that limiting global warming to 1.5°C requires a net reduction of 45% in global CO2 emissions in 2030 relative to 2010’.Footnote 56

These four inconsistencies undermine the credibility of the Court's assessment of Shell's mitigation duties. In fact, these observations may lead one to question whether it would be possible for a court properly to assess the requisite mitigation action of a corporation (or a state) based on global temperature targets.Footnote 57 Finally, the judgment gives no indication of the burden that this duty of care imposes on Shell: whether it imposes crippling costs on the group, or allows it to continue business as usual.Footnote 58

5. AN ALTERNATIVE METHODOLOGY

Martti Koskenniemi makes a distinction between two types of reasoning in international law: ‘descending reasoning’, which infers norms from general principles that form the structure of international law; and ‘ascending reasoning’, which induces rules from general state practice.Footnote 59 He also shows a tension between these two types of reasoning: between ‘utopian’ arguments fuelled by deduction from general principles, and more ‘apologetic’ arguments based on ascending reasoning. The gap between these two types of reasoning is particularly wide with regard to climate change mitigation, a domain where states and observers almost unanimously recognize that far more needs to be done than is being done. Agreement on the ambitious 1.5–2°C targets, for instance, was not accompanied by commensurate national commitments,Footnote 60 let alone consistent corporate practices.

The Hague District Court has clearly a predilection for descending reasoning; it infers the content of Shell's mitigation obligation from international agreements and scientific reports, in isolation from any consideration for sectoral practices. The Court rightly dismisses the objection that if Shell reduces its operations another company will fill the void: Shell must comply with the law, notwithstanding what other companies do.Footnote 61 Yet, if no, or very few, companies actually practise the standard defined by the Court, this begs the question: can this standard really be identified by a court as the most likely content of an open-ended legal norm? By relying exclusively on descending reasoning and discarding relevant sectoral developments, the Court is arguably not merely interpreting the law as it is (lex lata) in the light of the standard of care generally accepted by society; rather, it is imposing its vision of the law as it should be (lex ferenda).

This approach is inconsistent with prevailing interpretations of the duty of care as relying in part on an ascending reasoning. The standard of care, in the Netherlands and elsewhere, is often interpreted by reference to an imaginary person, who is variously referred to as bonus paterfamilias,Footnote 62 ‘the man on the Clapham omnibus’,Footnote 63 or simply ‘a normal’Footnote 64 or ‘reasonable’Footnote 65 individual – namely, a person adopting an ordinary level of diligence.Footnote 66 While this standard can often be inferred from common sense, such inference must stand the test of consistency with social practices, as recognized in various legal traditions. In English law, Christian Witting characterizes the argument that the defendant ‘conformed to the common practice of those engaged in the activity in question’ as ‘obviously … relevant’ to the interpretation of the standard of care.Footnote 67 In US law, the Second Restatement of Torts suggests that the standard of care must be determined by looking ‘to a community standard’.Footnote 68 Civil law jurisdictions have interpreted statutory provisions in a similar manner,Footnote 69 including in the Netherlands, where the concept of ‘proper social conduct’ in Article 6:162(2) BW has been understood as pointing to the standard that ‘a reasonably acting person’ would follow in the same situation.Footnote 70 To interpret the standard of care, ‘it is necessary to compare the motorist with other motorists, the sportsman with other sportsmen, the doctor with other doctors, the solicitor with other solicitors’Footnote 71 – and, presumably, Shell with other oil-and-gas companies.

As such, the standard of care applicable to Shell depends not only on the content of international agreements and scientific reports about what ought to be done against climate change, but also on what could be expected from an average or reasonable company – the Clapham petrol station (or the multinational behind it). The conduct of such companies is the result of complex decision-making processes that courts cannot merely surmise. Rather, a good way of determining what may be expected from an average company would be to observe the common practices of similar companies. Accordingly, the case at issue could not be decided on reasonable bases without a review, albeit of a summary nature, of what other oil-and-gas corporations are doing (or not doing) with regard to climate change mitigation. In particular, the court would need to discuss the development of transnational initiatives aimed at reducing CO2 emissions in oil-and-gas production – for instance, by reducing flaringFootnote 72 and methane leaksFootnote 73 – and to identify good practices from other companies.Footnote 74 Admittedly, ascending reasoning would not define a particularly clear-cut standard, and certainly not a very ambitious one. Many initiatives may be empty promises or instances where business interests overlap with mitigation action; these initiatives fall short of what would be necessary to achieve the 1.5–2°C targets.Footnote 75

Closer scrutiny may suggest discrepancies in tort law between references to an ‘average man’ and to a more ‘prudent’ or ‘careful man’.Footnote 76 These discrepancies reflect the need to find a midpoint between ascending and descending reasoning: whereas an ‘average person’ standard suggests a purely ascending reasoning, a ‘careful person’ standard would allow a court to seek a middle ground between ascending and descending reasoning by imposing on a company a standard slightly more stringent than that commonly followed by the average company. The Court may even have to take into account the rapid evolution of the standard of care applicable to climate change mitigation: more efforts will probably be expected from an average or careful company in 2030 than is expected today. All in all, a legal analysis that relies also in part on an ascending reasoning could be more openly subjective, but also more consistent and, altogether, more convincing.

6. CONCLUSION

This case comment has argued that the Hague District Court's innovative decision is not fully convincing. As in the Urgenda judgment, the Court struggles with the task of assessing an entity's requisite mitigation action. Nothing in the judgment explains why the Court concludes that Shell must reduce its CO2 emissions associated with its activities by 45% by 2030, compared with 2019, rather than, for instance, 25%Footnote 77 or 19%,Footnote 78 or compared with a 2010 baseline.Footnote 79 Arguably, the issue lies not just in the execution but also in the Court's methodological choices, as neither international agreements nor climate science provide a sufficient basis to determine Shell's requisite mitigation action. The case comment has outlined an alternative methodology based partly on an ascending reasoning, where the Court would seek to induce a standard of care from an observation of common practice in the relevant economic sector. Relying on ascending reasoning, in combination with descending reasoning, would be more consistent with the function of courts to apply the law, rather than to make the law.
