# Contributors: Acknowledgements Between 2022 and 2024, the Association for Low Carbon Transition (ABC) set up a **Working Group (WG)** dedicated to the evolution of the Bilan Carbone® method, composed of: * The ABC team, including members of the board of directors * Recognised historical experts who contributed to previous working groups or have demonstrated their expertise * Subject-matter experts called upon occasionally for specific topics * Experienced experimenters and representatives from the membership colleges among the current year's members After several months of reflection, the WG reached a consensus on the directions and developments that need to be integrated into the method. The [summary of recommendations](https://www.bilancarbone-methode.com/methode-bilan-carbone-r-en/appendices/bibliography#labc-et-les-ressources-complementaires-au-bilan-carbone-r) of the Working Group (WG), published at the beginning of 2023, is available to members.
