The document discusses proposed revisions to two United Nations statistical classifications:
1) The International Standard Industrial Classification of All Economic Activities (ISIC) is being revised from version 3 to version 4 to improve international comparability and relevance for new industries. Key changes include new groupings for information/communication and waste management.
2) The Central Product Classification (CPC) is also being revised from version 1.1 to version 2.0, considering a new section for information products. It aims to better classify non-financial assets and services related to their use.
