Summary:
On 28 February 2026, a case was filed at the Kuala Lumpur High Court that challenges Malaysia’s inaction on deforestation, linking it explicitly with the obligation to combat climate change. The applicants, all Malaysian youth, argue that their government’s inaction on deforestation breaches the constitutional rights enshrined in the Malaysian Constitution (MC), namely the right to life (Art. 5(1) MC), which the Malaysian courts have previously recognized as encompassing the right to a healthy environment, and the right to equality (Art. 8(1) MC), given that deforestation disproportionately burdens youths and future generations. They argue that the government breached the expectations of maintaining forest cover that it had consistently created since 1992, and that it was bound to protect forests under the public trust doctrine. They seek a mandatory order requiring the government to take all necessary steps to prevent deforestation by avoiding dips below 50% forest cover, and to report on its progress in this regard. To make this claim, the applicants draw on expert reports, including a report on “50% Forest Cover: Assessing Malaysia’s Compliance with Forest-Climate Commitments” that notes the global and local cooling effect of forests, as well as their capacity for carbon sequestration. The expert report notes that:
Studies from the Amazon suggest that ecosystem degradation above 25% of a total forest area could result in a “tipping point” and cause the entire ecosystem to systematically die out; this not only results in a loss of biodiversity but causes a forest complex to become a net-emitter of CO2 (Gatti et al., 2021). The risk of deforestation causing a Malaysian rainforest to reach this “tipping point”, whether in isolated forest patches or in larger complexes, have not been sufficiently studied and so remains a major threat to Malaysia’s progress in achieving its net-zero target.
