The Hawai‘i Supreme Court affirmed a trial court’s denial of oil and gas companies’ motions to dismiss the City and County of Honolulu and Honolulu Board of Water Supply’s (Honolulu’s) common law claims seeking to hold the companies liable for allegedly deceptive marketing and failure to warn of the climate change impacts of their products. With respect to the motion to dismiss for lack of personal jurisdiction, the court concluded that the minimum contacts test for specific jurisdiction was satisfied. First, the court found that Honolulu’s claims “arise out of” or “relate to” the defendants’ sale and promotion of oil and gas in the state. Second, the court found that the seven-factor test for determining whether exercise of specific jurisdiction was reasonable weighed heavily in favor of concluding it was reasonable. In particular, the court found that Hawai‘i had a “significant interest” in providing its residents “with a convenient forum for redressing injuries inflicted by out-of-state actors.” Third, the court rejected the companies’ contention that due process also required “clear notice” that the defendants could be subject to specific jurisdiction. With respect to the companies’ motion to dismiss for failure to state a claim, the court held that neither federal common law nor the Clean Air Act preempted Honolulu’s claims. The court first concluded that because the Clean Air Act displaced federal common law claims regarding interstate pollution abatement and damages, the federal common law could not govern in this case and could not preempt Honolulu’s claims; only the Clean Air Act could preempt the claims. The court further found that federal common law preemption arguments would fail, even if federal common law was not displaced, because Honolulu did not seek to regulate emissions. The court also found that the defendants waived any argument seeking to expand federal common law to tortious marketing and that, in any event, such an argument would fail because regulation of marketing conduct is traditionally a state-governed area. Finally, the court held that the Clean Air Act did not preempt Honolulu’s claims under any theory of substantive preemption (express, field, or conflict).

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Justice is the ethical and political framework that addresses fairness, including issues of responsibility, rights, and structural inequity.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

The management and allocation of funds, assets and investments to meet various objectives

Codes and standards are regulatory instruments that specify minimum standards to protect health and safety. This ranges from performance standards, which prescribe outcomes while allowing flexibility to achieve compliance, to the more prescriptive approach of technology-specific standards.

Actions or measures to adapt freshwater, coastal and marine systems to climate change.

Hot temperature extremes are daily maximum temperatures  that were exceeded on average once in a decade or once in 50 years, and includes heatwaves.

The release of heat-trapping gases, primarily from human activities such as burning fossil fuels, agriculture and industry.

A long-lived, colourless gas, chiefly emitted from fossil fuel combustion, deforestation and cement production.

Actions to reduce emissions in energy generation and supply.

Risks to the ecosystem health of the marine environment, including ocean warming, ocean acidification, and ocean deoxygenation, harming biodiversity, species health, ecosystem services, and coastal community livelihoods.

Extreme weather refers to events where a weather variable exceeds (or falls below) a threshold. Meaning it is significantly different from the average or usual weather pattern.

A drought is an extended period of unusually dry weather marked by a significant and sustained lack of precipitation, falling below a specific threshold over a large area for more than a month

Terrestrial means "of the earth" and relates to the risks to ecological system that includes all living organisms and their interactions within land-based environments, such as forests, grasslands, and deserts.

Air pollution involves harmful contaminants in the air, affecting both indoor and outdoor environments. It can lead to health issues like respiratory diseases and heart problems, and climate impacts such as global warming. Pollutants can damage plants, trees, habitats, and water bodies like rivers and lakes.

Oil is a combustible liquid fossil fuel composed mainly of hydrocarbons, occurring as crude oil and refined into petroleum products such as petrol, diesel and kerosene.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.

Any compulsory, unrequited payment to the government levied on corporations or individuals. This can be for environmental reasons, such as introducing a Carbon tax to set a price that emitters must pay for the greenhouse gases they emit.

The activities of industries involved in the production, distribution, and sale of energy, including electricity, gas, and renewables.

This sector involves the wholesale and retail selling of goods.

Activities that provide lodging, food, and entertainment services to guests, including hotels, restaurants, and resorts.

This sector creates and distributes information and entertainment through television, radio, print, and digital platforms.

Activities of government agencies and institutions that provide public services, enforce laws and manage public resources.

This sector includes firms and individuals offering specialised expertise in fields such as law, accounting, consulting, science and engineering.

This sector involves the distribution, treatment, and conservation of water resources.

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

Any substance with chemical properties that can cause physical harm to people or damage the environment, including ammonia, carbon monoxide, phosphine, chlorine, arsenic, cadmium, mercury, pesticides, dioxins, microplastics, benzene, asbestos, aflatoxins, fluoride, methanol, and toxins from marine sources.

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.
