Those working on the frontlines of social justice have long understood that change — be it political, cultural or systemic — does not come from the courtroom alone. The arguments we make, images we show, language we choose, and the tone we strike shape how problems are understood long before they are litigated. Narratives are the bridge between the world as it is and the world as it should be. And with enough momentum, they can become the catalyst for transformation. In the realm of climate justice — arguably the most rapidly developing human rights challenge of our time — we are witnessing a living dialogue between narratives and law. New ways of naming harm are making new legal arguments possible and, at the same time, legal victories also give us a more powerful vocabulary for justice. Bringing in insights from PLP’s Public Law and the Planet conference, this blog explores how this evolving relationship continues to redraw the map for law, advocacy and campaigning. Language matters When climate change first entered mainstream debate in the late 1990s and early 2000s, it was framed in resolutely technical terms: melting ice caps, rising sea levels, parts per million. As Catherine Higham, Senior Policy Fellow at the Grantham Research Institute on Climate Change and the Environment, observed during our conference, the human story was largely missing. The central question was “what is happening to the planet?”, not “what is happening to people?” That distinction proved decisive. As soon as climate change was reframed in human terms as something affecting lives, health, homes, and futures, it began to carry a different kind of urgency. It was no longer only a scientific problem: it became a legal and moral one. This shift in language has continued to evolve. As Kate Cook of Matrix Chambers noted, more recent questions have surfaced on whether “climate change” itself is too passive a phrase — one that is too detached from questions of harm and responsibility. Alternatives such as “climate violence” can disrupt that neutrality. It names harm directly and, crucially, implies agency for addressing it. Time has also been part of that framing. For years, climate change was cast as a problem of the future, a threat for generations to come. Increasingly, that framing has been swapped to something much more immediate: people are already living with, and dying from, its effects, namely those in Global South who bear the least responsibility for creating the problem in the first place. That temporal shift is legally significant too. A future risk invites precaution, but present harm invites remedy. Moving the narrative into the present tense can sharpen both the moral claim and the legal one. For those working in communications and advocacy, these shifts in language are profound. How the law talks back If language provides the initial impetus for legal action, the law can serve as a transformative mechanism rather than a passive recipient. Legal frameworks codify, sharpen, and recast narratives within a formal institutional context, in turn shaping narratives further. One example from human rights courts is the shift occurring in the legal understanding of state responsibility. Where climate action was once cast as a matter of political discretion — something to be balanced against competing priorities — it is increasingly being framed as a matter of obligation. Courts and litigants are articulating a different story: that failure to act is not merely a policy choice, but a breach of duty. That shift has consequences that go beyond semantics. It changes how inaction is perceived. A government that chooses not to act may be criticised; a government that fails in its legal obligations can be held to account. Litigation plays a crucial role here, not just in enforcing duties, but in making them visible. Legal language often finds its way into politics, media, and public debate. When courts or advisory bodies describe climate inaction as incompatible with fundamental rights, they’re shifting what can reasonably be argued, justified, or ignored, which helps set the terms of the wider public conversation. The same dynamic can be seen in debates over accountability: take the case of fossil fuel companies. Legal claims against them are moving the narrative away from vague blame on the ‘top dogs’ and toward clear, identifiable actors. By asserting that specific entities knew, made decisions, and acted in ways that caused harm, the law provides a clear line of responsibility which is vital in campaigning. Crucially, climate justice legal action also helps centre lived experience, giving attention to the individual whose home is lost or whose health is damaged. It introduces a vocabulary of dignity and fairness into a debate that has historically been abstract. As Higham noted, this shift has secured a “seat at the table” for sidelined communities. In this sense, the law doesn’t just respond to stories; it determines whose stories are finally heard. Yet there are limits to this approach. Human rights law can individualise harm, necessarily focusing on single victims or violations, while climate change is collective and cumulative, and remains difficult to prosecute. For this reason, legal action is not the whole story — particularly when it takes place in the Global North. Much of the important climate justice work is being done by community-led and Indigenous movements, who continue to shape alternative paths forward. Building power outside of the courtrooms has always, and will remain, a vital part of the path to climate justice. A two-way street The relationship between language and law is not linear. It is iterative, dynamic, and mutually reinforcing. Narrative shifts make new legal arguments possible, expanding what counts as harm, what remedies might be considered proportionate, and what forms of inaction unacceptable. Legal developments, in turn, feed back into the narrative landscape, legitimising claims, elevating voices, and clarifying responsibility. Choosing the right words, framing the right argument, or bringing the right case at the right moment are not separate acts — they are part of the same project. The map is still being drawn. Those who understand both the language and the law will have the greatest hand in drawing it. For more information, watch PLP’s free webinar – Introduction to public law for environmental campaigners.
