Environment Principles
Marriott International aspires to be the global hospitality leader that demonstrates how responsible hospitality
management can create economic opportunities around the world and be a positive force for the environment.
As global travel increases, Marriott has an obligation to mitigate our business impact on the natural environment.
It is our policy to comply fully with all applicable international, federal, regional, state and local environmental
laws, ordinances and regulations where we operate. Because we strive to operate our hotels with optimal
efficiency, we are committed to offering our communities an opportunity for a better and more sustainable future.
By our example, we hope to inspire associates, guests and partners to take action in the communities where we
live and work.
