The UN's World Health Organization has declared a Public Health Emergency of International Concern in the Democratic Republic of the Congo. Roughly 1,700 people have died of Ebola during the ongoing outbreak. This is only the fifth time that WHO has declared a global health emergency. The are hoping that the declaration will free up money from wealthy countries. Read more below from The Scientific American.


The World Health Organization (WHO) has declared the worsening Ebola outbreak in the Democratic Republic of the Congo (DRC) a public-health emergency of international concern (PHEIC). The move came amid renewed fears that the virus could spread beyond the DRC’s borders.


The declaration is the WHO’s highest level of alarm. This is the fifth time that the agency, an arm of the United Nations, has declared a global emergency—a step it reserves for events that pose a risk to multiple countries and that require a coordinated international response.

More than 2,500 people have become ill and nearly 1,700 have died during the DRC outbreak, making it the second-worst on record. The WHO’s investigations have suggested that the virus began spreading in the eastern DRC a few months before the outbreak was declared in August 2018.


“Now is the time for the international community to stand in solidarity with the people of Congo,” said WHO director-general Tedros Adhanom Ghebreyesus at a press briefing on 17 July.

From International Institutions and Global Governance Program Emission reductions alone are unlikely to prevent severe climate change effects. Geoengineering proposals are a way forward, but they need legitimate and effective governance.


This Global Governance Working Paper is a feature of the Council of Councils (CoC), an initiative of the Council on Foreign Relations. Targeting critical global problems where new, creative thinking is needed, the working papers identify new principles, rules, or institutional arrangements that can improve international cooperation by addressing long-standing or emerging global problems. The views and recommendations are the opinion of the authors only. They do not necessarily represent a consensus of the CoC members, and they are not the positions of the supporting institutions. The Council on Foreign Relations takes no institutional positions on policy issues and has no affiliation with the U.S. government.


The Challenge


More than twenty-five years after the adoption of the UN Framework Convention on Climate Change (UNFCCC), global emissions of greenhouse gases are still rising. The Paris Agreement aims to keep the average temperature increase to “well below” 2 degrees Celsius (preferably 1.5 degrees Celsius), but projections show 3 to 3.5 degrees Celsius of warming by 2100, compared to the roughly 1 degree Celsius above pre-industrial levels experienced today. A recent report by the Intergovernmental Panel on Climate Change (IPCC) concludes that in order to mitigate the most severe effects of climate change, the world would need to reduce carbon dioxide emissions by 50 percent between 2018 and 2030 and reach net-zero emissions by mid-century—a mitigation pathway that seems politically and economically implausible.


Emission reductions alone are unlikely to prevent severe climate change impacts. Researchers and policymakers are already considering additional measures, often clustered under the term geoengineering (or climate engineering), which encompasses deliberate large-scale interventions into the climate system. Carbon dioxide removal methods would draw down previously emitted carbon dioxide from the atmosphere and enhance the effects of conventional mitigation over time. Solar radiation management (SRM) would temporarily suppress the temperature increase and some of the associated effects, instead of addressing emissions, the root cause of global warming (see figure 1). Such proposals require legitimate and effective governance.

The most prominent SRM method would quickly reduce the amount of incoming sunlight by continuously injecting reflective particles into the lower stratosphere (see figure 2). A small coalition of powerful countries could potentially perform stratospheric aerosol injection and alter the global mean temperature much faster than any other climate policy measure. SRM thus poses significant risks and governance challenges, both geophysical and geopolitical. Depending on the chosen deployment scheme, there could be adverse effects on regional precipitation patterns and crop growth or a risk of ozone depletion, among other risks. Given the natural variability of the climate system and an incomplete understanding of the earth’s climate system, attributing harms geophysically would be quite difficult. For example, SRM methods could regionally reduce precipitation from one year to another, but precipitation could also be reduced without SRM. Therefore, geopolitically, perceptions will matter much more than scientific accuracy. The belief that countries deploying SRM causes extreme weather events would create fertile ground for international conflict. Furthermore, it is unclear what the exact target global mean temperature should be, and who could legitimately make that decision, given the regionally uneven distribution of risks and benefits.

No targeted governance for SRM exists, and discussions address its potential rather than a ready-to-deploy technology. Some multilateral agreements—such as the Convention on Biological Diversity (CBD), the Vienna Convention for the Protection of the Ozone Layer, and the Environmental Modification Convention (ENMOD)—cover parts, but none is comprehensive. SRM is still at an early stage of research and development, and the potential risks and benefits of techniques such as stratospheric aerosol injection, marine cloud brightening, and other sunlight reflection methods differ substantially and have varying governance requirements. For SRM, the dominant approach by national governments and in multilateral forums can be characterized as “wait and see.” Yet the first outdoor experiment releasing particles in the stratosphere—currently planned for 2020—will likely shift the perception of SRM worldwide and create a sense of urgency around governance, probably highlighting fears of unregulated research and “emergency-mode” deployment by a small group of countries and companies.


Recommendations


SRM governance could draw on existing international regimes or could emerge from principles and procedures for research experiments. A prerequisite, however, is for state and private actors to agree on the potential role of SRM in the overall climate change regime and to recognize its limitations. To achieve legitimate and effective SRM governance, state and private actors should pursue the following steps.


Acknowledge the trade-off between targets and instruments. A Swiss-led proposal that suggested an expert assessment on geoengineering and its governance, made to the Fourth Session of the UN Environment Assembly (UNEA) in March 2019, failed, unsurprisingly. Until now, most governments, civil society organizations, and climate researchers have avoided an in-depth conversation on SRM. The reasons for reluctance differ substantially. Most climate policy advocates and scientists fear that debating governance and normalizing SRM as part of the policy mix could obstruct mitigation efforts by creating the misleading perception that injecting aerosols could be a substitute for reducing emissions. Governments fundamentally opposed to massive emissions reductions either do not want to debate SRM because it would mean acknowledging that climate change is a serious threat, or they avoid a governance conversation because they do not want to bind their hands prematurely.


In light of a trajectory to warming of more than 3 degrees Celsius and already visible climate change effects, governments will have to deal with the trade-off between ambitious temperature targets and SRM. Its potential as a concept is not going to disappear. This does not mean that SRM would have to be deployed in the likely case of an overshoot of the 1.5 to 2 degrees Celsius threshold and accelerating harms. But it does mean that governments have to assess different types of risks, address the underlying norm conflict between precaution and harm minimization, and be held accountable for their decisions, even if they opt for an SRM moratorium or ban.


Strive for flexible and anticipatory governance. Today, deploying SRM is still a speculative concept, built on natural analogues (for example, temperature effects of large-scale volcano eruptions) and globally coordinated computer modeling. SRM methods could be unable to deliver on their promises, and geophysical and geopolitical side effects could arise. Such emerging and potentially disruptive technology cannot be governed through comprehensive institutional architectures designed in advance, since those would likely prove either too restrictive or too permissive in light of subsequent developments.


Many technological, environmental, and political assumptions held today could change in the future. For example, one popular notion is that SRM will be in the interest of industrialized countries but not the Global South. In the 2030s, however, governments from the most vulnerable regions might demand SRM deployment. Likewise, the widely held assumption that deployment of stratospheric aerosol injections would be comparatively inexpensive could turn out to be false, because of either unexpected engineering challenges or the costs associated with accompanying liability schemes. Existing legal schemes and the role of insurance regimes for testing or deploying SRM do not live up to the anticipated challenges.

Accordingly, governance arrangements should coevolve with respective SRM technologies, aiming to be at least one step ahead of research, development, demonstration, and—if the world ever reaches this stage—deployment. Such an approach will necessarily be patchy, using existing forums and regulations and also creating new ones better fit for this purpose.


Treat SRM as part of the global climate policy regime. In order to establish a regular exchange on governance, the UNFCCC should make stratospheric aerosol injection and other geoengineering methods a legitimate object of global climate governance. In this global setting, states and private actors have confronted SRM with distrust and demands for an outright ban (sometimes even on research). But events like the launch of the Stratospheric Controlled Perturbation Experiment (SCoPEx), currently planned as a U.S.-based research activity for 2020, could change the public perception and swiftly open up the conversation on SRM. Critical parties in the global climate regime, like China and the European Union, would have to start talking about the need for SRM governance, even if only in response to other parties’ actions.


Two issues can be addressed by integrating SRM methods under the UNFCCC regime: acceptance and control. Regarding acceptability, the parties to the UNFCCC should aim for a comprehensive consensus that SRM cannot be a substitute for mitigating emissions. Mitigation is part of the genetic code of the UNFCCC and a fundamental environmental protection claim. The more the world achieves with conventional mitigation and carbon dioxide removal, the smaller the scope of potential SRM deployment schemes (see figure 1). Moreover, parties support the climate regime on the basis of multilateralism and the balancing of interests on a variety of contested issues (mitigation, adaptation, finance, and loss and damage). Thus if some parties seriously consider SRM—for example, as a possible emergency approach—the extension of the negotiations agenda could raise the acceptability of talking about SRM as part of international climate policymaking.


The UNFCCC might worry about a shift of the control over climate system parameters into the hands of only a few countries. This concern could be addressed by a mix of trust-building and surveillance, politically as well as technically, because it touches upon many geopolitical tensions that exist beyond the climate regime. Embedding SRM in the climate regime would entangle the most potent parties (large countries with the means and will to deploy) in climate-bargaining.


The UNFCCC—supported by closely affiliated institutions like the IPCC, the UN Environment Program (UNEP), and the World Meteorological Organization (WMO)—should become the major political venue and information hub on SRM and its governance. This would ensure that both political debate and research and development are embedded in the multilateral climate regime.


Hedge the risk of uncoordinated action. The parties to the UNFCCC could be unwilling or unable to deal with SRM constructively. Since decision-making under the UNFCCC is consensus based, a minority of countries could block any meaningful debate, or agreed-upon outcomes could deliver overly restrictive or weak guidance. A restriction from the UNFCCC would probably not hinder interested parties such as nation-states, private enterprises, or scientists from moving forward with SRM research, development, demonstration, or even deployment. Their motivations may not align with the global climate regime. International law does not prohibit SRM, although some provisions of existing environmental agreements can be applied—such as the Montreal Protocol on Substances That Deplete the Ozone Layer, CBD, and ENMOD.


Potentially disruptive technology options like stratospheric aerosol injections—which could affect international security or agricultural yields—could also be considered by a different set of political and commercial actors, thus going beyond the realm of climate or environmental policymaking under the United Nations. Decisions on deployment would ultimately lie in the hands of heads of state and governments, bringing broader considerations into play, including the need to show political or technological leadership and the capability to act in times of perceived crisis.


If governments and multilateral and civil society organizations want to hedge the risk that a single state or a small coalition could move ahead with emergency SRM deployment, they should establish institutions that not only allow for thorough dialogue on governance but also can coordinate the next practical steps in areas beyond climate governance. Given the early stage of research on SRM, major powers such as the United States and China will be reluctant to restrict their options by consenting to a tight set of rules. At the same time, none of them would want to see a competing power acting unconstrained and unmonitored. As long as high uncertainty exists about the benefits of unilateral action, countries will have little interest in striving for global governance.


A high-level representative body could be another entry point for global governance, for example a high-level commission on SRM or geoengineering, following the example of the UN-mandated World Commission on Environment and Development under Gro Harlem Brundtland (1983–87), which elaborated the basic interconnections that enable sustainable development. Practical outcomes of such a process—which would require broad participation beyond national governments—could be programs to strengthen existing international agreements related to SRM, improve capacities for regional cooperation and conflict resolution, or develop monitoring systems. Supported by a transparent stocktaking, assessment, and knowledge hub, national interests could evolve in the context of a comprehensive international debate. Such a process could make the benefits of a global governance approach on SRM much more tangible.


Enhance and use research governance. Research on SRM, notably field experiments, requires principles and procedures that over time could—in a bottom-up manner—lead to mutual learning and feed into norms and regulations for global SRM governance.

A decade of coordinated modeling studies assessing the climate system effects of different SRM interventions and a vast body of accompanying social science research, including on public perceptions and governance issues, explains the strong demand for field experiments. They help sharpen understanding of physical and chemical processes and test technical equipment that could be used in SRM deployment. Outdoor experiments could also deliver evidence that SRM does not live up to its promises. Experiments could therefore help avoid risky bets on future technological options to address global warming at the expense of ongoing emission reductions.


Past SRM experiments, like the controversial Stratospheric Particle Injection for Climate Engineering (SPICE) project in the United Kingdom that aimed to test an aerosol delivery mechanism, show that transparency and accountability of research is critical, including openness about research objectives, methods, and results. Norms could be established by setting up enforceable codes of conduct for responsible SRM research, adopted by project funders and national research organizations. Some of those organizations—for instance, the U.S. National Academies of Sciences, Engineering, and Medicine—have already started to chart out SRM research agendas. Codes of conduct could develop in parallel in different countries and add to mutual learning about appropriate research procedures that could facilitate global norm-building in SRM governance. If high standards for responsible SRM research evolve in countries where such research takes place, it would be reasonable for the UNFCCC or the WMO to host an international clearinghouse for SRM research. This would allow policymakers to coordinate research priorities and enable effective public participation. Read the Conclusion


Using International Standards as an Agile Tool for Governance


Artificial Intelligence (AI) is now firmly on the international agenda. In May, Organisation for Economic Co-operation and Development (OECD) member states endorsed the Principles on Artificial Intelligence, the first international agreement of its kind. France and Canada are expected to formally launch the International Panel on Artificial Intelligence (IPAI) at the G7 meeting in August. These efforts build on a flurry of national and regional initiatives.




Despite this progress, the emerging global governance landscape for AI faces three challenges: ensuring non-governmental participation, achieving buy-in from key governments, and adapting to rapidly changing technology. However, there is another promising yet often-overlooked tool of global governance: international standards-setting bodies can complement emerging AI governance efforts with strengths that address these three challenges.


International standards bodies have a long history of channeling non-governmental stakeholder participation into global impact. Standards bodies, including the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and the Institute of Electrical and Electronics Engineers (IEEE), convene experts from academia, business, and government to develop standards by consensus processes. Past standards have ensured global interoperability in everything from computer hardware to quality management protocols.


These standards can have a pervasive and profound impact in everyday life. Hundreds of thousands of companies from more than 170 countries have implemented environmental sustainability standards at considerable expense, and ISO and IEC have developed safety standards used in industries ranging from self-driving cars to nuclear energy. ISO standards have even been used by the United Nations to develop arms control guidelines. Standards-setting bodies and their standards could be similarly impactful for AI.


Today, international standardisation efforts for AI have buy-in from key governments. The US Executive Order on AI prioritised standards development, and the US government is now developing a standards engagement strategy. In a notable contrast to other governance efforts to-date, China has also taken a seat at the table. The Chinese government published a standards strategy in 2018 that prioritised international standards development. That same year, the ISO/IEC Joint Technical Committee for Information Technology created a standards sub-committee for Artificial Intelligence (SC 42). China and the US both contested leadership of SC 42, resulting in an unusual compromise: the committee has a US secretariat, is chaired by a US employee of Huawei, and held its first meeting in Beijing. SC42 is now undertaking foundational research and standards development. The IEEE is also developing a series of standards that address, inter alia, transparency, algorithmic bias, and fail-safe design.


AI is rapidly evolving: it is a general purpose technology, the final forms and impacts of which are uncertain. Preemptive agreements on steam engines, electricity, or the internet would have struggled to shape their transformative impacts. The governance-by-principle and research synthesis approaches taken by the OECD and IPAI, respectively, sensibly acknowledge this. Standards can offer a governance tool, grounded in technical reality, that complements these other efforts.


For example, there is widespread agreement, from the EU, US, OECD, China, and beyond, that “trustworthy AI” is a priority; ongoing standards development in transparency, robustness, and safety can help deliver this focus into practice. Furthermore, the process of standards development and adoption can support trust, not simply for public consumers, but, significantly, among researchers, labs, and countries. Once developed, standards can enable a global market for AI systems and encourage their widespread and safe deployment.

For a technology that has surprised experts by its speed of breakthroughs, timelines for governance matter. Precautionary efforts to support means for governance to scale up are warranted. It took the OECD’s principles on data privacy nearly 40 years to get substantive teeth, only doing so following EU action in response to the Snowden revelations. In contrast, once the development of a standard is initiated, it will normally take no more than four years to be published; still other expedited procedures are available if they are needed. Standards can help to rapidly establish guardrails in international and market competition in AI development.


Despite their strengths, international standards bodies are an incomplete piece of the larger global governance puzzle. Standards are most commonly adopted voluntarily. This means that, absent enforcement, malicious actors could simply disregard their provisions. Furthermore, business prioritises the development of standards that are needed to support market transactions.


Yet, standards are warranted across the AI life cycle to promote safety. Absent concerted effort from governments, concerned businesses, and civil society, these standards may be slow to emerge, if they do at all. There is yet another challenge demonstrated by ongoing trade tensions and challenges to technology firms like Huawei: increased politicisation of standards bodies would complicate this mode of AI governance.


International standards have an important role to play in the global governance of AI. In a recent report, I explore this role and offer recommendations for private-sector actors to support globally legitimate, high-quality standards. Global governance scholars and practitioners should actively consider how standards can support the development and enforcement of further global governance efforts. In the past, standards have been incorporated into international treaties, supported the global diffusion of regulation, and informed government policies as well as procurement contracts.


Today, we are early in the development of the technology and even earlier in its governance. Standards offer a first step to help erect guardrails in the international and market competition for AI. Let’s use them as the governance tool that they are.
