A groundbreaking plan to monitor carbon dioxide emissions at steel plants worldwide has provoked controversy over how transparent the industry needs to be in the fight against climate change. The International Iron and Steel Institute, which represents the industry, is going ahead with plans to gather emissions data and share these privately among members without identifying individual plants or producers. This is to discourage the "naming and shaming" of companies, which could discourage many potential participants from joining the voluntary scheme...John Elkington, founder and director of Sustainability, a London-based environmental consultancy, says: "I think the steel industry would find its scheme gained a lot more credibility if it committed itself to making the data publicly available."
