Carbon dioxide concentrations in closed or confined rooms can increase to 1,000 ppm within 45 minutes of enclosure. For example, in a 3.5-by-4-metre (11 ft × 13 ft) sized office, atmospheric carbon dioxide increased from 500 ppm to over 1,000 ppm within 45 minutes of ventilation cessation and closure of windows and doors.
Miami-Dade is considering cracking down on a heavily advertised home improvement funding program that has drawn hundreds of consumer complaints across the state and been the target of lawsuits and ...
Cap-and-Trade Program: Market-based carbon pricing program that sets a statewide cap on emissions. This cap declines annually and applies to large emitters that account for over 80 percent of California's GHG emissions. The California Air Resources Board (CARB) creates an allowance for each ton of carbon dioxide emissions. The number of ...

The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...

Carbon dioxide is a by-product of food metabolism and in high amounts has toxic effects including: dyspnea, acidosis and altered consciousness. [8] Arterial blood carbon dioxide tension. P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 and 45 mmHg (4.7 and 6.0 kPa). [9] Venous blood carbon dioxide tension
