Law plays an important role in reshaping and enforcing governance efforts in radical shifts and can function as a catalyst for transitioning governance towards sustainability. This article assesses the capacity of law to facilitate decarbonization as a radical societal shift. It argues that decarbonization demands fundamental and systemic restructuring in law and legal thinking. This should also be reflected in legal scholarship and, most importantly from the point of view of this article, in the methodological choices and approaches that legal scholarship relies on to study societal challenges. To that end, the article develops a new methodological approach (disciplinary comparison) through which to study law's capacities in respect of decarbonization as a radical societal shift. Disciplinary comparison can be used to gain information on both the friction and the synergies between legal disciplines. This new methodological approach will contribute to increasing insight into law's capacities for the radical, cross-sectoral change necessitated by the need to decarbonize societies.

法律在重塑和实施根本性转变中的治理努力方面发挥着重要作用，并且可以作为治理向可持续性转型的催化剂。本文评估了法律促进脱碳作为彻底的社会转变的能力。它认为，脱碳需要对法律和法律思维进行根本性和系统性的重组。这也应该反映在法律学术中，最重要的是从本文的角度来看，体现在法律学术研究社会挑战所依赖的方法选择和方法中。为此，本文开发了一种新的方法论（学科比较），通过该方法来研究法律在脱碳作为彻底的社会转变方面的能力。学科比较可用于获取有关法律学科之间的摩擦和协同作用的信息。这种新的方法论将有助于加深对法律能力的认识，以实现社会脱碳的需要所必需的彻底的、跨部门的变革。
