NPG Sees Link Between EPA Reports of Increased Greenhouse Gas Emissions and U.S. Population Growth


Alexandria, VA (July 31, 2013) – A recent report from the Environmental Protection Agency (EPA) heralded a slight decrease in U.S. greenhouse gas emissions in 2011.  However, the drop from 2010 was just 1.6 percent – and emissions since 1990 have actually risen by 8.4 percent.  A July report from the Earth Policy Institute found that fossil fuel emissions have risen by 2.6 percent each year since 2010, “hitting an all-time high of 9.7 billion tons of carbon in 2012.”


NPG President Don Mann expressed serious concern regarding America’s increasing output of greenhouse gases, a major contributor to climate change.  In a new NPG President’s Column, Mann sees a direct link between rising emissions and population growth.  “Emissions (per capita) multiplied by the population size equals total emissions.  That is simple arithmetic.  Why then is it universally ignored?”


“Our federal government disregards,” Mann added, “that – if per capita emissions remain the same – our population size is the principal determinant of the size of our greenhouse gas emissions.  What we urgently need to do to reduce emissions,” Mann explained, “is to reduce the size of our population so that it can eventually be stabilized at a sustainable level.”


The 2011 EPA Greenhouse Gas report found that “power plants accounted for about 67 percent of 2011 reported emissions.”  And a new Department of Energy report expressed serious concerns about America’s energy sector – specifically that, as climate change worsens, more energy breakdowns will occur.  “As new plants are built and additional energy is distributed to meet the needs of our ever-growing population and changing climate,” Mann added, “how could we not expect a significant increase in our emissions?”


“Beyond any question,” Mann concludes, “our country is already greatly overpopulated in terms of the carrying capacity of its environment and resources.  The size of our population is simply not sustainable over the long term.  To make it sustainable, we must slow, halt, and eventually reverse our population growth, then maintain it at that lower level.  Only by reducing our population can we ensure a stable and rich quality of life for the generations to come.”


Negative Population Growth is a non-profit membership organization which works to educate the American public and elected leaders regarding the devastating effects of population growth.



There is no remedy that can possibly avert disastrous Climate Change and Global Warming unless we first address the problem of world population size and growth, and its impact on the size of the greenhouse gas emissions that cause global warming.That means that we need to address the population size and growth of each nation, which together make up the world total.

World population, now over 7.3 billion, is predicted to rise to 9 billion by 2050, an increase of almost two billion, or 23%, in the short space of only 34 years from now.In the highly unlikely event that per capita greenhouse gas emissions could possibly be decreased by an equal percentage in such a short space of time (a blink of an eye) the total amount of worldwide emission would remain the same!

From this simple illustration it would appear that without drastically reducing the size of world population, there is no solution to the problem.None at all.So then why do our world leaders pretend that there is one?What is to be gained by pretending rather than by proposing a solution that would solve the problem – a reduction in the size of world population to not more than 1- 2 billion?
