Green project management incorporates environmental stewardship into the project management process. It looks beyond traditional deliverables to improve sustainability. The challenge is making projects more environmentally friendly throughout the project life cycle. A green project manager considers environmental impacts in all phases, from planning recycling and reducing energy use, to monitoring progress on green objectives and reusing materials after completion. While balancing environmental and other goals, even small changes by project managers can have a positive cumulative impact on the environment over time.
