Archiving has always been about selecting, preserving and making available. But while historians and archivists share a common interest in archived information, their vision of material relevance and record-keeping occasionally differ. Additionally to this ancient divide, digital archiving has brought new challenges for both communities. In this paper, I will first discuss conceptual continuity lines between analog and digital archiving of textual material at a general level. In a second step, I will examine both analog and digital archiving under the lens of their environmental footprint and the challenges it brings about in a context of resource shortage like the climate and biodiversity crisis. I will not concentrate solely on strategies pertaining to the archived material itself, but will also consider the ecological impact of historian work on this material, among others the now popular use of AI tools. I will plead for a balanced vision of historical sciences, one that slows down to assess costs and benefits each step of the way to the preservation of and research on Heritage.
