The tone set by your management practices can have a significant impact on the success of your sustainability effort. Here are a few sustainable management practices to consider.

Create a vision, mission statement and core values that reflect your commitment to sustainability
Vision is a concrete picture of where you want to be in 3-4 years, where anything is possible.
Mission statement is why you exist. It answers the question, “What is the ultimate result of your work?” It focuses on the outcomes and results, and can easily be memorized.
Core values are characteristics that define you. They are the values you want to see more evident in your daily lives.
Publically communicate your commitment to sustainability
Understand how your business affects the environment and the community by assessing your practices and the full life-cycle of your products and services.
Include sustainability considerations in your strategic planning, training, performance evaluation and policies
Monitor and measure your progress toward sustainability, seeking continuous improvement
Celebrate your successes and learn from your mistakes
