A Low-Carbon Economy (LCE) and a Low-Fossil Fuel Economy (LFFE)
Written by Dusty Miriam Gutierrez
A Low-Carbon Economy (LCE) or Low-Fossil Fuel Economy (LFFE) refers to an economy which has a minimal output of greenhouse gas (GHG) emission into the atmosphere. Carbon dioxide, an undesirable byproduct of many industrial and commercial processes, is a greenhouse gas. That is, it is believed to contribute to global warming.
Attempts to reduce carbon dioxide emissions address major concerns among industrial nations. First, an LCE addresses unreasonable accumulation of GHG (specifically carbon dioxide, CO2) in our atmosphere. Some scientists claim that the overconcentration of this gas could dangerously change our climate in the near future. Second, an LCE is necessary to reduce dependency on fossil fuel while developing alternative energy sources and energy-efficient products. Third, oil and natural gas are depleted resources. As they are depleted through time, coal might become a strong substitute in the demand for energy. Coal power plants are the greatest industrial emitters of carbon dioxide gas and could worsen global environmental situations. Fourth, as depleted resources become more limited, their global demand will most likely increase, bringing unprecedented price increases in future decades. Fifth, the Tyoto Treaty, originally ratified in 1997, needs to be renewed in 2012. This treaty is an international agreement that requires substantial reduction of greenhouse-gas emissions, especially by big emitters such as the US, China, and India.
There are many things our country can do to break away from its dependency on petroleum, natural gas, and other fossil raw materials. Our country needs to develop the use of low carbon-biofuels such as cellulosic fuels (i.e. bioethanol, biobutanol). Our country needs to expand its use of energy-efficient products, such as the creation of fuel-efficient vehicle shapes and configurations, and more alternatives of flexible-fuel vehicles. Our country needs to turn to more energy-efficient methods, such as petroleum fuel surcharges (which increase consumer cost), greater use of marine and electric-rail transport, less use of air and truck transport, and more pipeline capacity for common fluid commodities such as water, ethanol, butanol, natural gas, and hydrogen
There are various technical solutions to achieve an LCE while continuing to exploit non-renewable resources. The solutions are increases in renewable-energy use, national energy efficiency, carbon-capture and storage technology, and new fuels development. Carbon capture and storage (CCS) is a technological process that separates carbon dioxide from other gases produced by large stationary power plants. The carbon dioxide is then transported and stored deep into the earth or into the ocean.
There are various low-carbon energy sources which can be developed. Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat, all of which are naturally replenished. Renewable energy also includes the further development of domestically-produced biofuels, solar cells, fuel cells, wind farms, ocean wave energy, and greater use of geothermal heat pumps. Nuclear power is another proposed strategy to provide carbon capture and storage (CCS). To be successful, all of these technical solutions and strategies must have the support of the Federal Government through investment, regulation, and education.
There are several economic proposals made to transition the US to an LCE such as command and control regulations, emission trading, and carbon tax. Emission trading, or a “cap and trade system,” has recently emerged as a preferred tool for addressing global greenhouse gas (GHG) emissions.
A cap and trade system works by setting a fixed limit on emissions (the cap), and distributing rights to emit, called allowances, up to the level of the cap to regulated entities. These regulated entities can then transfer the allowances among themselves. (This is trading.) Any increase in allowances and emissions of one firm is matched by a corresponding reduction of allowances and emissions elsewhere. The cap is reduced over time, and over time greater emissions reductions are obtained.
Under acap and trade regulatory system, firms can either reduce emissions to the level of their allowance holdings, through whatever technologies or process improvements are available, or they can purchase allowances to cover additional emissions. A firm that finds it relatively easy and inexpensive to reduce emissions can free up emissions allowances which it can then sell to other firms. This buying and selling of allowances establishes a market price for the permit, which reflects the underlying cost of reducing emissions of that pollutant.
Summary
Global implementation of LCEs is proposed as a means to avoid catastrophic climate change, and to reach an ideal zero-carbon economy. The aim of the LCE is to regionally integrate all domestic sectors of the economy such as manufacturing, agriculture, transportation, and power generation around materials and technologies that produce energy with less GHG emissions. Another aim of the LCE is the international effort to reduce the greenhouse gas carbon dioxide.
Solutions to achieve an LCE require the continuous effort to exploit non-renewable resources. The adaptation of an economic strategy that measures unit price of emission production is necessary to spur the development of non-renewable resources. The elimination of emission leakage requires complete geographic coverage of carbon dioxide emissions. The implementation of an economic system is necessary to reduce carbon dioxide emission levels at national, multi-national, and/or global levels. The increased participation of the US in the international effort is necessary to reduce the greenhouse-gas carbon dioxide and to allow for more global regulation of CO2.
Regardless of the global economic and financial situation around the globe, the concept of an LCE must be part of the economic plans of all governments around the globe. The concepts of an LCE and new innovation and technologies, not only address climate change, but could also spur the economies free of fossil fuel and bring together stronger economies into the 21st Century. For the US, an economy free of fossil fuel could mean the beginning of the Third Industrial Revolution, with a wave of new energy policies, innovations, and new ways of organizing business. New waves of technical and organizational exploration could carry the American industrial society into new levels of production domestically and globally.
