  2. Indoor air quality - Wikipedia

    en.wikipedia.org/wiki/Indoor_air_quality

    Humans are the main indoor source of carbon dioxide (CO 2) in most buildings. Indoor CO 2 levels are an indicator of the adequacy of outdoor air ventilation relative to indoor occupant density and metabolic activity. Indoor CO 2 levels above 500 ppm can lead to higher blood pressure and heart rate, and increased peripheral blood circulation. [85]

    en.wikipedia.org/wiki/Demand_controlled_ventilation

    Demand controlled ventilation (DCV) is a feedback control method to maintain indoor air quality that automatically adjusts the ventilation rate provided to a space in response to changes in conditions such as occupant number or indoor pollutant concentration. The most common indoor pollutants monitored in DCV systems are carbon dioxide and ...

  9. Greenhouse gas emissions by the United States - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions...

    In 2018, carbon dioxide was estimated to approximately be 81% of all USA greenhouse gases emitted in 2018. Natural sinks and reservoirs absorb carbon dioxide emissions through a process called the carbon cycle. Sinks and reservoirs can include the ocean, forests and vegetation, and the ground. [21]
