Milieudefensie Launches Second Climate Lawsuit Against Shell Over Fossil Fuel Expansion
Dutch environmental group Milieudefensie has initiated a second major climate lawsuit against Shell, intensifying legal pressure on one of the world’s largest fossil fuel producers to halt new oil and gas developments and accelerate emissions reductions.
The case, formally launched with the filing of a summons, centres on demands that Shell stop investing in new fossil fuel fields. According to Milieudefensie, continued expansion of oil and gas production is fundamentally incompatible with global climate goals and risks deepening dependence on polluting energy sources.
At a press conference in the Netherlands, the organisation unveiled a large-scale world map highlighting around 700 undeveloped oil and gas fields in which Shell has a stake. The visual campaign underscores the scale of potential future emissions tied to the company’s portfolio. One of the identified gas fields lies beneath Egmond-Binnen, the location chosen for the announcement.
Donald Pols, director of Milieudefensie, argued that the persistence of fossil fuel investment is both environmentally and economically damaging. He said high fuel prices demonstrate the fragility of the current energy system, with consumers bearing the costs while major producers continue to profit. He maintained that scientific evidence has long shown that limiting global warming requires an immediate halt to new oil and gas development.
Research from the Intergovernmental Panel on Climate Change and the International Energy Agency supports the claim that existing fossil fuel reserves already exceed the amount that can be burned while keeping temperature rises within internationally agreed limits. Both bodies indicate that even full use of current fields could push global warming beyond 1.5°C, the central target of the Paris Agreement.
Milieudefensie’s legal action is partly a response to statements made by Shell to investors in 2025, in which the company signalled plans to continue expanding liquefied natural gas production beyond 2030. The group also points to a previous court ruling in the Netherlands, which found that corporations have an obligation to reduce emissions and may be acting contrary to climate agreements if they pursue new fossil fuel projects.
Lawyer Roger Cox, representing the organisation, said the earlier judgment established that companies like Shell have a duty to contribute to climate targets and protect human rights. Building on that precedent, the new case seeks to translate broad legal principles into more concrete requirements.
A central demand is for Shell to introduce binding interim emissions targets covering the period between 2030 and 2050. Campaigners argue that while the company has announced a long-term ambition to reach net-zero emissions, it lacks a credible, detailed pathway to achieve that goal. They also contend that current strategies rely too heavily on continued fossil fuel investment, particularly in gas, rather than scaling up renewable energy.
The case comes as the first climate lawsuit against Shell continues to move through the courts, with a key hearing scheduled at the Dutch Supreme Court. Together, the two cases represent one of the most sustained legal challenges faced by a fossil fuel company over its climate strategy.
Milieudefensie and its youth wing argue that the broader energy crisis reinforces the urgency of the transition to renewables. They point to examples such as Spain, where increased investment in wind and solar power has reduced the influence of fossil fuels on electricity prices. For campaigners, such cases demonstrate that a shift away from oil and gas is not only necessary but achievable.
The lawsuit reflects a growing trend of climate litigation aimed at holding corporations accountable for their role in global emissions. As legal, political and economic pressures converge, cases like this are likely to play an increasingly prominent role in shaping the future direction of the energy industry.
