The International Court of Justice’s (ICJ) July 2025 advisory opinion marks a global legal landmark, affirming that climate change is an existential threat requiring binding international obligations for all nations. This ruling elevates the 1.5°C Paris Agreement goal to a legal benchmark and establishes that duties to prevent, mitigate, and remedy climate harms arise not only from treaties like this agreement but also from customary international law.
Interest in enforcing these obligations was reignited at COP30, where the call for full compliance with the ICJ climate ruling was a key demand from states and civil society. Additionally, the Belém Action Mechanism, launched at COP30, highlighted the crucial work needed to promote human rights, just transition, inclusion, and participation in climate action—reinforcing the idea that effective and fair climate solutions must be rooted in rights and equity.
Coinciding with this development, Malaysia launched its inaugural National Action Plan on Business and Human Rights (NAPBHR) 2025-2030 in August 2025 under the Legal Affairs Division of the Prime Minister’s Department, providing a framework and governance tool that complements these global obligations by guiding businesses on climate and human rights duties. This blog will share how businesses in Malaysia can put the NAPBHR into action in corporate strategy and risk management, in meeting both global and domestic expectations.
As a United Nations (UN) member state, we are automatically a party to the ICJ Statute, the UN's principal judicial organ. This legally obliges Malaysia to respect ICJ rulings and to adhere to stricter climate and environmental standards. It has significant implications for businesses, amid growing investor pressure for more disclosure.
Malaysia has integrated human rights considerations into its climate strategies and is progressing with its Nationally Determined Contributions (NDCs). The October 2025 NDC 3.0 target peaks emissions by 2030 and a reduction of 15-30 million tonnes of CO₂ by 2035, while safeguarding environmental and human rights protections. Key mitigation efforts supporting these objectives include expanding renewable energy capacity, enhancing energy efficiency, and encouraging sustainable land use practices.
As a dualist system, Malaysia will strengthen its climate commitments by formally incorporating these international agreements into national law, making them legally binding, enabling civil society and the courts to support more robust climate action and mitigate legal and reputational risks.
ICJ decisions in contentious cases are legally binding between nations, but they depend on inter-governmental cooperation for enforcement. Advisory opinions, including those on climate change like this ruling, have significant moral and legal influence, shaping international norms and national policies, despite lacking direct enforcement. Regardless of treaty ratification, all countries have a duty under customary international law to reduce emissions, prevent environmental harm, and protect climate-related human rights, as the ICJ ruling raises climate obligations to a global legal standard that cannot be avoided by non-membership or withdrawal from treaties. This expands accountability and strengthens the legal basis for global climate action.
By affirming obligations from customary law beyond treaties, the 2025 ICJ ruling reinforces Malaysia’s responsibility to regulate corporate climate impacts, protect rights, and support vulnerable communities. Such legal clarity encourages both the government and business sectors to embed human rights and environmental standards into their laws and practices, positioning Malaysia’s NAPBHR as a vital framework for climate justice and sustainable development.
Malaysia already actively aligns itself with regional and global frameworks supporting sustainable development, human rights, and climate commitments. It participates in the ASEAN Climate Change Initiative and follows the UN Principles on Business and Human Rights, fostering regional cooperation and corporate accountability. Recent trade agreements with the US, EU, and Japan cover sustainable development and environmental protections, further encouraging Malaysian industries to boost sustainability practices and align with international climate justice.
The NAPBHR creates a framework to embed human rights into governance, labour, environment, and community rights. It aims to strengthen legal protections, boost corporate accountability, and provide remedies for human rights breaches. Key areas include:
The NAPBHR functions as a strategic guide that helps businesses to:
These recommendations offer strategic ways to embed the NAPBHR into corporate strategy, enhancing resilience, compliance, and sustainable value for businesses:
The 2025 ICJ ruling establishes climate governance as a legal obligation, while Malaysia’s NAPBHR provides a framework for businesses to meet both global and domestic expectations. By integrating human rights into strategy, risk management, and disclosures aligned with ICJ and NSRF standards, leaders can turn compliance into a competitive edge for sustainable growth, risk mitigation, and future-proofing. Transparent reporting and robust risk integration enhance investor confidence and resilience. Together, the ICJ ruling, the NAPBHR, and the NSRF create a strong roadmap connecting law, policy, and corporate strategy, ensuring Malaysia’s legal and corporate landscape remain resilient and adaptable to future climate and human rights challenges.
