Indigenous peoples are disproportionally vulnerable to climate change. At the same time, they possess valuable knowledge for fair and sustainable climate adaptation planning and policymaking. Yet Indigenous peoples and knowledges are often excluded from or underrepresented within adaptation plans and policies. In this paper we ask whether the concept of epistemic injustice can be applied to the context of climate adaptation and the underrepresentation of Indigenous knowledges within adaptation policies and strategies. In recent years, the concept of epistemic injustice has gained prominence, indicating that someone has been unfairly discriminated against in their capacity as a knower (Fricker 2007, 1). We argue that many climate adaptation policies are epistemically unjust towards Indigenous peoples because of the underrepresentation of Indigenous knowledges by showing how the case of Indigenous knowledges in climate adaptation planning and policy satisfies five conditions of epistemic injustice. We further consider what challenges there are to integrating local and Indigenous knowledges within development in general, and climate adaptation strategies in particular and how these can be addressed. Whether the lack of Indigenous knowledges in climate adaptation policies constitutes an epistemic injustice matters because an injustice denotes an unfair (dis)advantage to one group – whether by design or default – that ought to be remedied and redressed.

土著人民特别容易受到气候变化的影响。同时，他们拥有公平和可持续的气候适应规划和决策的宝贵知识。然而，土著人民和知识往往被排除在适应计划和政策之外或在其中的代表性不足。在本文中，我们询问认知不公正的概念是否可以应用于气候适应的背景以及适应政策和战略中土著知识的代表性不足。近年来，认知不公正的概念越来越突出，这表明某人作为知情者受到了不公平的歧视（Fricker 2007, 1）。我们通过展示气候适应规划和政策中的土著知识案例如何满足认知不公正的五个条件，认为许多气候适应政策在认知上对土著人民是不公正的，因为土著知识的代表性不足。我们进一步考虑了将地方和土著知识整合到一般发展中存在哪些挑战，特别是气候适应战略以及如何解决这些挑战。在气候适应政策中缺乏土著知识是否构成认知上的不公正很重要，因为不公正表示对一个群体的不公平（不利）优势——无论是有意还是无意——应该得到补救和纠正。
