# AEC Sustainability Can [NFTmicro](/aerariumchain-docs/aerariumchain-aec/nftmicro-tm.md) be more sustainable than a museum freebie?\ Sure, because we use [**Algorand**](https://www.algorand.com/), an eco-friendly blockchain. NFTs respect the environment and the museum’s ethical thinking allowing museums to keep working without losing right on assets. Wouldn’t it be more ethical and sustainable purchasing a NFT that helps preserve the artistic heritage than a magnet at an exhibition? #### To find out more about the small environmental impact that the Algorand blockchain has, read [the dedicated section](/aerariumchain-docs/aerariumchain-aec/ecosystem/algorand.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
