This article contributes to the general debate on the link between population growth and the environment by analyzing the impact of demographic factors on two air pollutants. At the same time, it also con- tributes to a more focused debate on how population size and other demographic factors should be taken into account in future projections of air pollutant emissions. It is relevant to the large and still growing body of literature on the so-called environmental Kuznets curve (EKC), which posits that environmental pollution is first increasing and then decreasing with rising per capita income levels (see for example Cole, Rayner & Bates, 1997; Grossman & Krueger, 1995). In. | EPA FACT SHEET Proposed Carbon Pollution Standard for New Power Plants On March 27 2012 the Environmental Protection Agency EPA proposed a Carbon Pollution Standard for New Power Plants. This common-sense step under the Clean Air Act would for the first time set national limits on the amount of carbon pollution power plants built in the future can emit. EPA s proposed standard reflects the ongoing trend in the power sector to build cleaner plants that take advantage of American-made technologies. The agency s proposal which does not apply to plants currently operating or new permitted plants that begin construction over the next 12 months is flexible and would help minimize carbon pollution through the deployment of the same types of modern technologies and steps that power companies are already taking to build the next generation of power plants. EPA s proposal would ensure that this progress toward a cleaner safer and more modern power sector continues. Power plants are the largest individual sources of carbon pollution in the United States and currently there are no uniform national limits on the amount of carbon pollution that future power plants will be able to emit. Consistent with the US Supreme Court s decision in 2009 EPA determined that greenhouse gas pollution threatens Americans health and welfare by leading to long lasting changes in our climate that can have a range of negative effects on human health and the environment. FUTURE POWER PLANTS The nation s electricity comes from diverse and largely domestic energy sources including fossil fuels nuclear hydro and increasingly renewable energy sources. The proposed standard would not change this fact and EPA put a focus on ensuring this standard provides a pathway forward for a range of important domestic resources including coal with technologies that reduce carbon emissions. The proposed rule would apply only to new fossil-fuel-fired electric utility generating units EGUs . For purposes of this rule .
