Research on Green Marketing Strategy in Enterprises Based on Low Carbon (LC) Environment

The ecological environment of this planet-Earth has been damaged by industrial pollution. In the Copenhagen General Assembly of 2009, it has become the focus issue attracting the attention from various countries in the world how to reduce carbon emission. As one of economic powers, China yet becomes a large environmental polluter. According to the calculation of World Bank, during two decades from 1980 to 2000, China has generated 14% contribution rate to the world GDP in terms of its economic growth. However, China also pays a high price in resource consumption, high energy consumption and environmental destruction for this. As is pointed in Environmental Green Book of 2007,there were about 75% of waters in Chinese lakes suffering significant pollution and the contamination rate of urban waters reached as high as over 90%, hence causing more than 300 cities in China suffer water shortage. At present, China has become the second largest emitter of greenhouse gases in the globe and the loss that environmental pollution engenders to national economy holds about 10% in GDP. And the area of cultivated land in China also decreases at the speed of about 1.6 million hectares per year, hence with severe land degradation and water and soil erosion phenomena. According to another statistic report, Chinese GDP in 2004 held appropriately 4% in the globe but the consumed primary energy took up almost 12 percent of the globe, with fresh water holding 15 percent, aluminum oxide 25 percent, rolled steel 28 percent and cement 50%. In a word, the extensive economic growth pattern/mode has forced China to face serious resource and energy crises. Due to a series of negative effects brought about by environmental pollution and various inconveniences caused to life, consumers are also motivated to pay more and more attention to the environmental problems engendered by random disposability after products are used. As a result, the design and production of green products and energy conservation in production process become particularly important,and various green products has become more and more common in market, making green energy conservation and environmental protection have become the starting point for people to go shopping.

Green Low Carbon Design in the Application of Energy-Saving Building

The article from the energy and environment issues, elaborates the need for the development of energy-saving building, describes the characteristics and advantages of green energy-saving buildings. For the problem of high energy consumption in buildings, analyses the application of green building materials in the building envelope, from environmental protection material, renewable energy and the overall system design aspects discusses the low carbon energy- saving design, summarizes the significance of the building energy efficiency evaluation and energy consumption assessment, concludes and looks forward to the prospect of the development of green energy conservation construction.

Energy conservation, CO2, and other greenhouse gas reduction

Energy conservation as well as CO 2 and other greenhouse gas reduction present long-term challenges to our society, and the problems are exacerbated by the rapid consumption of materials and energy and signifi cant emissions of greenhouse gas and toxic gases. By 2050 the world’s oil production will be half of what it is today. Capping CO 2 in the atmosphere at 450 ppmv will require its sequestration. Metallurgical industries and transportation systems are the main energy users and the main producers of greenhouse gas. Production of renewable energy and saving energy in metallurgical processing are two keys to energy conservation. As an example, solar cell energy is a well known renewable energy and it is claimed as a green energy by most people. However, if the feedstock, especially for multi-crystalline silicon, is included, solar cell energy is not a green energy since during the production of the high purity silicon, signifi cant energy is consumed, much CO 2 is emitted, and several non-green processes, such as strong acid leaching, are included. Furthermore, during the wafer slicing process of a high-purity silicon ingot, over 50% becomes slurry wastes and there are no successful industrial processes to recycle these valuable wastes. In order to save energy, traditional industrial processes should be optimized. Furthermore, reuse, recycling, and recovery of metals and materials should be emphasized since these processes usually use less energy than the primary production processes.
