    This paper outlines the research and development of new additive packages and component technology and their interactions with environmentally acceptable base fluids and thickeners, which enables bio-based and eco-friendly grease products to achieve a high level of performance. Many current environmentally acceptable greases meeting the European Union (EU) Ecolabel criteria for lubricants suffer from relatively poor performance compared to synthetic greases of similar cost. A summary of the current EU Ecolabel criteria is detailed and the implications for grease formulators are discussed. Careful selection of the base fluid and thickener type is needed in order to meet the Ecolabel criteria and to provide an acceptable level of performance to the end user. A list of potential additives to be used was drawn up following a review of available current ecological and toxicological data. By combining the proper base fluid, thickener, and additive combinations, a grease formula capable of meeting ASTM D4950 GC–LB multi-purpose performance classification has been formulated. A further development was shown to pass the requirements of the ISO 12924:2010 “Lubricants, industrial oils and related products (Class L)–Family X (Greases)–Specification.”
