25. What are the Creative Green Tools? The Creative Green Tools are a free set of unique carbon calculators developed by Julie's Bicycle specifically for the creative industries. They’re used by over 3,000 organisations across 50 countries to understand the environmental impacts of cultural buildings, offices, outdoor events, tours and productions. The Tools make it easy to measure your organisation’s key environmental impacts, from the energy use of your buildings, to the waste generated at your festivals, to the travel/material impacts of your touring productions.
