“The worst impacts of climate change would occur if greenhouse gas (GHG) levels in the atmosphere go higher than 550 ppm CO2 equivalent. The current level is 430 ppm today, and it is rising at more than 2ppm each year. The global emission level needs to be at least 25 percent below current levels by 2050 to avoid the harmful GHG level going past the threshold.”

Effects on Society from cap-and-trade approach
One very useful resource that I found online is a discussion paper “A U.S. cap and trade system to address global climate change” written by Robert Stavins from Harvard University. In his paper, he discussed about the effects of cap-and-trade approach on the industry, society, government revenues etc. A policy analysis model crated by Palsev.S from MIT serves as the basis of the discussion. Overall, I rate this source as highly credible.
Companies nowadays are facing a major challenge to cut costs, remain efficient, and maintain customer loyalty and retention simultaneously. Not only the pricing power of internet and discount retailers are growing, but the recent Great Recession also make consumers pay close attention to their spending habit and everybody seems to be going to shopping with pay-less state of mind. Unfortunately for sellers, price can be a double-edge sword: it can be an excellent strategic weapon in a highly competitive market while it can also destroy profits and hurt consumers at the same time.

Colorado River Abstract (Photo credit: cobalt123)
Water may be the most abundant thing on earth, but 99% of it is saltwater that is unsuitable for human consumption and use. Two thirds of the remaining one percent is locked up in the polar ice caps and glazers. So, only one third of one percent of the total of world’s water is shared between human and other organisms.
Water management has become a top priority in UN agenda. The United Nations estimated that 30% of the world population in 50 countries will face water shortages by 2025. According to the World Water Organization, as many as 135 million people may die from water-related diseases by 2020 if no action is taken to meet basic water needs. Continue reading
According to EPA, total US greenhouse gas emission in 2010 from various economic sectors is as follow.
It looks like the majority of the emission comes from consumers, who are direct users of electric transportation and commercial and residential sectors. Industry and Electricity consists of more than 50% of the emission from U.S. Continue reading

This picture comes from greenpeace.org East Asia campaigns for air pollution. This picture embodies the extreme case of air pollution and uncontrolled carbon emission from industrial processes. The photo portrays a group of people having to protect their nose and mouth to make sure they don’t inhale harmful particles from the atmosphere and unable to have a nice day out, with the famous palace of the Forbidden City buried in the smog, set in the background. This can be a very strong message to the society that air pollution can significantly decrease quality of life and hence, it is a serious problem.
According to EPA (environmental protection agency), gas emissions from the United States totaled 6,821.8 million metric tons CO2 in 2010 and rose by 3.2% from 2009 to 2010. In 2009, the Unites States account for 18% of the total green house gas emission in the world.
Currently, the two most popular emission control policies are cap-and-trade system and carbon taxes. Those approaches are not incompatible with each other and a number of countries use one or both across various business sectors to control emission. Hence, in my paper, I would like to investigate which approach is best suited to which sector and recommend an emission control for the next government. Continue reading
