Research the concept of sustainability ("reducing your carbon footprint"), strategies and solutions for healthcare facilities. do a web search on reducing your carbon footprint, or reducing your carbon footprint in healthcare.
In the first section of your paper, summarize sustainability strategies and solutions for healthcare facilities.
In the next section of your paper, discuss how a facility you are familiar with has pursued such strategies. Discuss your observations and opinions of what has worked and what needs work. If you are not working in a health facility, it will be fine to discuss your current facility (can be non-health facility) where you work, or a facility where someone you know works.
