The main principle of backcasting is to start with the desired future state. This approach is particularly useful in strategic planning and environmental sustainability, where organizations envision a goal or outcome they wish to achieve in the future and then work backwards to identify the steps necessary to reach that goal. This method contrasts with traditional forecasting, which often relies on projections based on current trends and historical data.

By beginning with a clear vision of where an organization wants to be, backcasting allows for a creative and comprehensive exploration of potential pathways to achieve that future. It emphasizes the importance of long-term goals and encourages decision-makers to think outside of existing limitations. Thus, using this technique facilitates innovative solutions and strategic alignment towards achieving the envisioned future, resulting in more effective and purpose-driven planning.
