The British cell-phone provider reclaimed the top spot in 2008 (it ranked No. 5 last year and No. 1 in 2006) by upping its green game. Vodafone in April said it would chop its carbon dioxide emissions in half by 2020; the company plans to do so largely by improving the energy efficiency of its global mobile-phone networks. Vodafone also gets good grades for reporting the details of the campaign - and whether or not it's going well - on a continuous basis.
Such transparency apparently is part of the Vodafone culture: The firm reports its progress on past commitments, but also discloses deadlines for future promises, such as its pledge to recycle 95% of network equipment waste (March 2009) and plans to reduce work-related accidents that cause lost time by 10% (March 2011).
Vodafone engages stakeholders on issues related to global competitiveness, and asks for their input in creating new products. Consequently, the business is a leading innovator of socially responsible products: Recent offerings include text-to-speech software for blind people and easy-to-use handsets for the elderly.
