In a recent release, Vodafone announced that by 2020 it will reduce its CO2 emissions by 50% against its 2006/7 baseline of 1.23 million tonnes. In addition, the Big Red mobile operator will be focusing on developing products and services which will help customers limit their own emissions.
The idea here is to leverage improvements in energy efficiency and increasingly rely on renewable energy sources.
Currently they are gathering data about the carbon footprint of their newly acquired companies in India and Turkey and climate change targets for these businesses will be announced in due course.
Vodafone (and the rest of us) is hoping that their public commitment will also encourage others to take similar action.
