Entry eight: The Sustainability Law and Policy Clinic, part one (ClientEarth)

Not all legal clinics help individuals with their problems. Some take on the problems of the planet.

Launched in September 2025, the Sustainability Law and Policy Clinic brings together around twenty students from across the LSE to undertake real-world legal and policy work on pressing ecological questions. This year, the Clinic is pursuing two ambitious projects: one asking how the world’s largest banks might be held legally accountable for the carbon emissions they finance; the other exploring how the River Thames might be involved in the policy decisions that shape and affect its own future.

Pretty big stuff… Today, we begin with the banks.

The sustainable finance project is a collaboration with ClientEarth, the environmental law NGO titan. It tackles a critical, if often overlooked, question in climate litigation: can the world’s largest banks be held legally responsible for the emissions they enable? Not the emissions from their own office buildings, but the billions of tonnes produced by the fossil fuel projects their balance sheets make possible. In the jargon of climate finance, these are called ‘financed emissions.’ In the jargon of tort law, they are a rather tricky problem of causation.

‘The Sustainability Clinic project with ClientEarth provided a previously unfound clarity that aligned with my real-world experience regarding the ‘entrenchment’ problem—the continued financing of expanding fossil fuel projects. I view the Clinic as an opportunity to learn from brilliant minds and work alongside inspiring colleagues in the service of a greater good. The experience has indeed been more than I could have envisioned, both intellectually and personally—a true landmark from my year at the LSE.’

The partnership with ClientEarth’s Accountable Finance team aims to explore how climate attribution science and strategic litigation might be used to hold banks and financial institutions legally accountable for their financed emissions over time. The studentsare not tasked with bringing a case themselves—though several look as though they would rather enjoy the attempt. Instead, their job is to survey how courts across jurisdictions have approached causation in climate cases. They catalogue the existing methodologies for measuring financed emissions and assess their legal robustness. From this, they distil a set of guiding principles capable of anchoring future litigation strategies.

‘I’ve experienced working with NGOs before, but none that were the size of ClientEarth. Everyone I encountered from the organisation was extremely kind and helpful, and seemed genuinely invested and interested in our work.’

Your average weekend pastime, clearly... Yet the students have thrown themselves at it with characteristic disregard for their own free time.

‘The clinic’s most significant impact on my understanding of environmental law was the reassurance that it is okay to be a dreamer; it is, in fact, ordinary to face uphill battles and asymmetrical forces when seeking justice in a profit-driven world. Changes to the status quo are birthed within the minds of dreamers and then mediated into the mainstream through action.’

One of the recurring observations in this diary has been that clinical legal education transforms learning by making the stakes real. In the Employment Clinic, the stakes may be a client’s livelihood. In the Sustainability Clinic, they are nothing less than the question of whether the financiers of the global economy can be held accountable, through law, for their contribution to a warming planet. The cohort comprises twelve students, drawn from across the globe, and studying across five departments at the LSE in central London. The stakes are planetary.

It is, in every sense, a privilege to watch.
