Several challenges exist in this area. The range of existing and new eco-labels is making it confusing for customers to understand what it all means, especially when private company labels are added to the mix. Some labels have strict requirements to adhere to while others require very little effort to get certified. No one label covers all sustainability issues and it is unlikely that labelling will be standardized in the foreseeable future. However, we are still in the early days of eco-labelling.
