Background: University campuses can be leaders of change by tracking carbon footprints and establishing strategies for reductions. The American University of Sharjah (AUS) has led this effort in the United Arab Emirates (UAE), establishing an Office of Sustainability to address energy consumption on its campus, resulting in a reduction of 30% by 2015. AUS campus uses the Greenhouse Gas Protocol to annually track carbon footprint. The purpose of this paper is to stablish a framework that institutions can use to calculate the carbon footprint (CF) on their university campuses. Methods: The GHG Protocol, which categorizes emissions into three scopes; 1: direct, 2: indirect, and 3: other indirect emissions, was used as a guideline. This paper covers the following: Scope 1: emissions from university fleet, Scope 2: emissions from electricity and water consumption, Scope 3: emissions from the university commute, limited business air travel and waste. The data for each category are analyzed and recommendations to reduce the carbon footprint are presented. Results: The total CO₂ emissions for the AUS campus in 2018–2019 were 94,553.30 tCO₂e. Additionally, the percentage contribution of total emissions for Scope 1, 2 and 3 were 0.37%, 61.12% and 38.51%. Conclusions: The two highest contributors of CO₂ emissions at the AUS campus are electricity consumption (60.91%) and university commute (36.54%). AUS has hosted numerous educational campaigns and awareness programs to try to reduce carbon emissions, which helped in reducing electricity consumption throughout campus; however, these are still insufficient; hence, the importance of quantifying the CF of the AUS campus. Based on the results obtained, recommendations can be made to reduce overall CO₂ emissions for AUS and other higher education institutions in the region and internationally.

In the Arabian Gulf, mangroves play a particularly important role in maintaining biodiversity. Water and intertidal sediments were collected from eight sampling locations in April 2017 to assess the environmental status of the mangrove forest in the Khor al Beida, Umm Al Quwain, which is one of the largest natural mangrove forests in the United Arab Emirates (UAE). Khor al Beida is also a breeding ground for the largest Gulf colony of a regionally endemic Socotra cormorant. Total metal concentrations of water and sediments were measured using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and ranged between 0.001–2.873 mg/L and 0.08–12683.02 mg/kg, respectively. Most metals were within permissible levels, except for copper, iron, aluminum, zinc, and nickel. Hazard Quotient calculations showed low risk to the ecosystem in relation to the presence of heavy metals, with the exception of zinc. Fifty-three diatom species of pennate benthic forms were identified in the intertidal sediments. For the first time in the UAE, diatom composition and diatom diversity values were quantitatively estimated in the surface sediments and a short sediment core. Overall, the assessment suggests that the mangrove forest is currently undisturbed and shows very little anthropogenic impact; yet, protection and conservation efforts are necessary in order to maintain its current status.
