This presentation summarizes energy saving initiatives at Alcatel-Lucent offices that have significantly reduced electricity and gas consumption. Major initiatives included installing smart meters for real-time energy monitoring, implementing a heating pump system that captures waste heat, reducing natural gas usage through operating changes, and improving cold production efficiency. These projects have led to savings of over 5,300 MWh of gas in 2007 and 70.5% savings from 2007-2013. Alcatel-Lucent's long-term commitment is a 50% reduction in its carbon footprint by 2020 through continued facility improvements, supply chain engagement, renewable energy sourcing, and enabling low-carbon communications networks.
