Cap and trade, who would it help, how would it work?
Because of world wide industrialization, all manner of pollutants were concentrated and released into the air and water of our planet. In the beginning the concentrations were low enough, or people could simply move away from them so that it did not affect our health and well being. Always there was an initial resistance by the parties involved to clean up their messes, but eventually public pressure was brought to bear, and the pollutant was either restricted, required to be recycled or cleaned up. The clean air and clean water acts have done much to make our air breathable again and clean up former sewer pits like Lake Erie, where the water is so clean that sport fishing and swimming is again possible. Even the Cuyahoga River in Cleveland, which was so polluted that it burned when I lived there, now flows clean into Lake Erie and has a National Park along its shores. Carbon dioxide is the latest pollutant to enter the world stage. Why is it a pollutant? the concentration of CO2 affects the net energy balance of the Earth. It's really quite simple, each day the earth is irradiated with a certain amount of energy from the sun (approximately 120 watts per square meter average), which heats the atmosphere and makes it pleasant to live over most of its surface for bipedals like us humans. At night, this is radiated out into the cold of space via infrared radiation, in a balanced cycle. The atmosphere allows this heat to escape, keeping the average temperature over the entire Earth quite nicely in balance. When we add CO2 to the atmosphere, we block this night time radiation more or less. The net result is a warming up of the average air temperature across the globe (along with all the negative effects this causes), until a new balance is obtained. There is no runaway heating effect, simply a new equilibrium at a higher temperature. Scientists feel that the net effect of this higher average temperature outweigh the positives, since most industrialized nations will not benefit (except perhaps Canada and Russia). The question is how to resolve this and begin to rein in the higher carbon levels to a manageable level. One of the ways is thru carbon credits. This may have some side benefits to those who own carbon sinks, such as forest land. In the latest National Geographic, there is an interesting article on just how carbon credits helps the forest industry, and how it promotes sustainable long term health of the wood products industry. Redwood forests once covered huge swaths of California some 50 miles wide and 400 miles long along the Pacific coast. These giant trees were much coveted by the building industry and fueled the housing boom in the West, as well as the rest of the nation. Since the late 1800's approximately 95% of the old growth Redwood trees have been harvested, some as much as 2000 years old. Those that were replanted are mere saplings compared with the original giants, trees that were 300+ ft high and as big around as a 747 airliner. Those old trees had dense hardwood, which was much coveted for its rot resistant properties. Replanted 50 to 100 year old trees have much softer wood and are not as desirable as the old growth giants. The timber industry in California has had its boom and bust cycles, so forest managers and researchers have been looking for ways that make the industry sustainable as well as profitable. It turns out that clearcutting replanted 50 year old trees is highly destructive to the environment, resulting in erosion, stream silting, destruction of salmon spawning grounds, etc, as well as yielding lower quality wood. It pits loggers against environmentalists and is not as profitable as it should be to the land owners. New management practices along with forest research now makes it clear that a new way of forestry can result in desirable outcomes for all parties concerned, and at the same time clean the carbon out of the air. How is this done? First, only 1/3 of the trees are removed in any one area, leaving larger trees to grow and giving them more light to grow faster. The best trees are left in a stand to accumulate denser heart wood, while mopping up huge quantities of CO2 in the process. Giant Redwoods are fantastic carbon sinks, and if left standing will earn carbon credits for the owners for as long as they are growing. The owners of the forest make short term profits by selling the trees that are culled while banking the ever increasing value of the largest trees. As the forest ages, these trees are worth more and more in carbon credits and in the dense heartwood that they are laying down in each yearly growing cycle. The forest becomes more valuable over time to the owner, and he can sell it to the next and the next for generations to come, always careful to cull only 1/3 of the growth at any given time. In this way the forest becomes a sustainable entity which has numerous benefits to the owner, to the surrounding communities, the loggers, and the environmentalists. It continues to grow and regenerate itself while continually increasing in value. Who buys these credits? They can be redeemed by power generating plants who want to use cheap coal, either here in the US or overseas. These credits will be tradable like any commodity in the future. It is a way for the forest owner to make a profit whether he cuts the trees or not, plus it gives the housing industry another option for sustainable wood products. It also turns out that older trees in other areas of the country, like the US south east and north east, also benefit from similar forest management, and that older pine trees also develop better quality wood than younger trees. It is also a very effective way to sequester CO2, which must be done one way or other for our nation's long term survival. |
