“…Carbon footprint impact on public health can have direct or indirect effects. The direct impact of carbon footprints on public health was explored under five thematic areas, which are: impact on extreme weather events (hurricanes, storms, and floods), impacts on temperature, impacts to air pollution, impacts to water-and foodborne diseases, and impacts to vector and rodent-borne diseases, while the impact of a carbon footprint on the economy was seen as an indirect impact on humans and a huge change in human lives [27].…”

Background: Climate change has continued to pose a global concern, as the resulting effect of the increase in greenhouse gas (GHG) emissions continues to have significant consequences on the planet and its inhabitants. One of the major sectors contributing to the greenhouse effect is the healthcare sector, however, it is one of the sectors that has been overlooked and under reported. Objective: This article aims at reviewing the carbon footprint of healthcare facilities in Nigeria and its impact on climate change, while highlighting important and effective strategies towards addressing it. Methods: Data was obtained through a systematic review of available research articles obtained online via PubMed and Google scholar search engines, using the key words; climate change, healthcare facilities, global warming, and carbon footprint. Results: Effective policy and regulatory frame works are essential towards addressing the carbon footprint of healthcare facilities; however a lot of gap still exists in curbing the effect of GHG emissions by healthcare facilities in Nigeria, as majority of healthcare facilities in Nigeria still rely significantly on the combustion of fossil fuels for generation of power due to its epileptic electrical power supply. Conclusion: There is great need in addressing the effect of the carbon footprint of healthcare facilities on climate change. This can be achieved through the use of renewable energy technologies like solar and wind power, as well as the use of energy conservative measures such as the use of LED lighting and High-efficiency Heating, Ventilation, and Air Conditioning (HVAC) systems.

Turbulent flow physics regulates the aerodynamic properties of lifting surfaces, the thermodynamic efficiency of vapor power systems, and exchanges of natural and anthropogenic quantities between the atmosphere and ocean, to name just a few applications of contemporary importance. The space-time dynamics of turbulent flows are described via numerical integration of the non-linear Navier–Stokes equation—a procedure known as computational fluid dynamics (CFD). At the dawn of scientific computing in the late 1950s, it would be many decades before terms such as “carbon footprint” or “sustainability” entered the lexicon, and longer still before these themes attained national priority throughout advanced economies. The environmental cost associated with CFD is seldom considered. Yet, large-scale scientific computing relies on intensive cooling realized via external power generation that is primarily accomplished through the combustion of fossil fuels, which leads to carbon emissions. This paper introduces a framework designed to calculate the carbon footprint of CFD and its contribution to carbon emission reduction strategies. We will distinguish between “hero” and “routine” calculations, noting that the carbon footprint of hero calculations—which demand significant computing resources at top-tier data centers—is largely determined by the energy source mix utilized. We will also review CFD of flows where turbulence effects are modeled, thus reducing the degrees of freedom. Estimates of the carbon footprint are presented for such fully and partially resolved simulations as functions of turbulence activity and calculation year, demonstrating a reduction in carbon emissions by two to five orders of magnitude at practical conditions. Besides generating a carbon footprint, the community's effort to avoid redundant calculations via turbulence databases merits particular attention, with estimates indicating that a single database could potentially reduce CO2 emissions by approximately O(1) × 106 metric tons.
