Is Software Carbon-Efficiency a Form of Greenwashing?

This article explores the nuanced relationship between software carbonefficiency and greenwashing. While carbon-efficiency aims to extract maximum value from every gram of carbon emitted by software, critics argue that it is a form of greenwashing, as it may not lead to an overall reduction in carbon emissions. It discusses the potential trade-offs and unintended consequences of emphasizing efficiency without considering the broader impact on total emissions. It also addresses the rebound effect, where increased efficiency can lead to increased consumption, potentially negating the benefits of efficiency improvements. The article discusses when efficiency is a good signal to drive behavior change, how through efficiency measures we can determine which growth is ''good growth'' and the need for increased standardization and transparency to avoid claims of greenwashing.
