We are committed to improving the environmental efficiency of our operations.
We measure our total environmental footprint — energy use, fuel consumption, water use and waste (generated, recycled and electronic) and analyze the data to optimize performance.
Our reporting includes over 12,000 facilities globally, from skyscrapers to data centers and ATM kiosks.
In 2010, we established a new set of environmental goals. By 2015 (2005 base) we aim to:
We will do this primarily by investing in energy efficiency, constructing green buildings, and optimizing our technology.

We remain committed to build all new facilities (branches, offices and data centers) to U.S. Green Building Council's LEED and U.S. Environmental Protection Agency's (EPA) ENERGY STAR certification standards.
In addition to LEED certification for 190 projects across nine countries, more than 60 Citi-managed buildings in the U.S. have earned the ENERGY STAR label.

In 2010, employees in 539 Citi buildings in 65 countries and 233 cities joined "Earth Hour," a campaign to turn off the lights for one hour. The effort raises employee consciousness regarding energy usage and increases Citi's participation in global efforts to reduce electricity dependence.
In 2010, we had more than 14,000 approved suppliers globally, in more than 100 countries. We purchase a wide variety of technology, workforce and business services, as well as office and facilities services.
We continue to integrate ethical, social and environmental factors into our global procurement practices, and promote them among our suppliers. In early 2010, we released our Statement of Supplier Principles. We circulated the Principles to approximately 3,000 of our core, approved suppliers and to all new suppliers to develop codes of best practice to improve their performance.

Citi has developed a supplier rating system to assess our global facilities supplier base of nearly 18,000 vendors to track the materials, recycled content, reusability and recyclability of the products we purchase, along with the overall sustainability of our vendors' business models.
