. Corning is a publicly traded company with a history of sustainability dating back to the early days of environmentalism. The company has a stated goal of reducing its environmental footprint and has made significant progress in reducing greenhouse gas emissions, energy consumption, and waste. However, critics argue that Corning's definition of sustainability is too narrowly focused on environmental issues and does not take into account social and economic impacts. For example, the company's use of conflict minerals has been criticized for contributing to human rights abuses in the Democratic Republic of Congo.
