Starbucks is known as a very responsible company. On their website they have a specific page dedicated to their corporate social responsibility (CSR). As a company, they focus on five areas of responsibility; Community, Environment, Ethical Sourcing, Wellness and Diversity.
I will focus on what they do for the environment. Starbucks focuses on recycling, energy, water, green building and climate change.
According to their website, their goal for recycling is "By 2015 we plan to have recycling available in all of our stores where we control waste collection and serve 25% of beverages in reusable cups." Last year 70% of their stores recycled at least one type of waste...they are continuing to try to make this percentage higher. To reduce their carbon footprint in their stores, they are working to reduce their energy consumption in their stores across the world. They are attempting to make 50% of the energy they use in their stores from renewable sources. They are also doing research in order to better understand how to use water in their stores. They are attempting to reduce the amount of water that they use in every store.
As you can see, Starbucks is specifically trying to reduce their effect on the environment in-house. They have set specific goals for the company, and are committed to achieving these goals.
