Advancing our sustainability

Successful companies make choices that are sustainable. Tellabs conducts its business in ways that respect people and protect the environment. We act with integrity to create long-term value for our customers, investors, employees, suppliers and communities.

Our top priorities for 2010

• Reduce energy consumption with more efficient products and operations. Our designers hold Design for Environment workshops, under Tellabs' global program to improve energy-efficiency and reduce waste as our products evolve. To help measure our carbon footprint, Tellabs completes the Carbon Disclosure Project survey. In 2009 we expanded our scope to include 100% of our facilities, which emitted 44,171 metric tons of CO₂. We will continue to report and work towards reducing our CO₂ emissions.
• Work with supply chain to responsibly manage materials and waste. We conducted our first survey of preferred suppliers and found that 98% of them adhere to a code of conduct. These codes set expectations for ethical, environmental and labor practices.
• Strengthen the communities where we live and work. Tellabs offers to match employee gifts of time and money, up to $2,000 per employee per year. Excluding employee gifts, Tellabs and the Tellabs Foundation contributed $1.4 million in 2009 to worthwhile causes.
• Proactively communicate our plans and progress. On page 19 of this report, Tellabs reports its progress in each area of corporate responsibility. We also share our plans for 2010.

We remain committed to open, honest communication about our efforts. For more detailed information on corporate responsibility, visit www.tellabs.com or contact us at corporate.responsibility@tellabs.com.
