In late July the UN International Court of Justice (ICJ) announced its long-awaited and highly-anticipated climate advisory opinion. The ICJ ruling represents an historic moment in climate accountability.
“Obligations of States in Respect of Climate Change”
In a rare unanimous decision, the ICJ opinion concluded “a clean, healthy and sustainable environment” is in part a precondition for the enjoyment of human rights including the right to life and the right to health. Consequently, the ICJ ruled states including their private actors are obligated to ensure the climate is protected from anthropogenic greenhouse gas emissions (GHGs) and can be held legally culpable by other harmed or unharmed states, groups and individuals for failing to protect the climate.
The 140-page opinion is the result of a 2023 UN resolution that requested the ICJ produce an advisory opinion answering two questions: what are states’ obligations under international law to ensure protecting the climate and what are the legal consequences for causing significant climate harm? In a failed attempt the US State Department opposed the resolution arguing the ICJ can only consider applicable climate treaties such as the 2015 Paris Agreement and to the exclusion of other rules of international law.
In sum, the ICJ found states have substantive, urgent and enforceable obligations under UN climate treaties and international laws to prevent significant harm to the environment from GHG emissions that includes those resulting from fossil fuel use. The court broadly defined fossil fuel use as the adoption of laws, regulatory policies and programs that promote fossil fuel production and consumption via leases, licenses and subsidies.
States must act using “all means at their disposal” that includes adopting appropriate legal and regulatory measures, acquiring and analyzing scientific and technological information and risk and impact assessments, meeting a duty of cessation and acting in good faith that includes a duty to cooperate and collaborate internationally. The ruling also allows for legal action to protect future generations. The court rejected the argument attributing harm on a case-by-case basis is unachievable stating it is “scientifically possible” to determine each state’s current and historical emissions. Without naming the US, the ICJ affirmed states not party to UN treaties must still meet their equivalent responsibilities under international law.

US Healthcare’s Contribution to Anthropogenic Warming
Because the ICJ recognizes an inherent link between anthropogenic warming and human rights, the opinion implies the right to health cannot be secured without addressing US health care’s own climate obligations. Meeting these pose a substantial challenge for the industry for several reasons.
US health care significantly contributes to anthropogenic warming. Per Northeastern Professor Matthew Eckelman, the industry accounts for a growing amount GHG emissions currently at over 600 million metric tons of carbon dioxide equivalents (CO2e), or 9-10% of total US emissions and 25% of global healthcare emissions. If US healthcare was its own country it would likely rank 9th, less than Saudi Arabia but more than Germany.
Two reasons largely explain US healthcare’s carbon footprint. The industry is immense. Despite providing care for 4% of the world’s population, last year it constituted a $5.3 trillion market or roughly half of total global healthcare spending. The industry wastes an enormous amount of energy. Despite spending over $5 billion annually on energy, equivalent to at least 15% of profits, hospitals are significantly energy inefficient because they continue to consume fossil fuels to first generate heat to produce electricity that is dramatically less efficient than using renewable resources that directly generate electricity or work demand. End-use energy inefficiency compounds the problem. For example, only a trivial number of hospitals are EPA Energy Star certified for energy efficiency. For the ten-year period ending in 2024, 85 or 1.4% of over 6,000 hospitals were on average certified.
