Index Difference Between Low
May 18, China Building Materials Circulation of the Association Building Trade carbon emission reduction roadmap.
Under the road map, from 2010, the construction industry from the “three highs” (high pollution, high energy consumption, high emission) production of “Guantingbingzhuan” into the “soft carbon reduction”, that is more With production technology, production means, technical upgrading and technological innovation, in order to achieve low-carbon Building Materials .
Specifically, the association’s goal is to make building materials industry carbon emissions by 2012 to 2005, about 56% reduction on the basis of that million to increase the value of building materials industry dropped to 7.33 tons of carbon emissions around.
However, the low carbon building materials assessment and standard-setting encounter a difficult, low carbon building materials are being organized to discuss the work of standard-setting trial Certification Center of China Advanced Construction Materials Project Master Chen Lu said carbon material is a full life-cycle approach, can not provide a product subject to a monitoring report to the raw material – production – use – the entire process on the post-processing waste considerations.
In accordance with the life cycle assessment (LCA) method, currently the popular Environmental protection Materials will only be a part of low carbon building materials in addition to clean, also requires low power consumption and low emissions. Products to meet raw material in the acquisition, production, processing and use of the process to minimize consumption of natural resources, and can recycling and waste recycling or safe, conducive to environmental protection and human comfort and health.
But how to define the boundaries of assessment, how to use the appropriate calculation of energy conversion, namely, how to convert carbon dioxide equivalent energy consumption of products, as well as throughout the life cycle and determine how to calculate energy consumption, have not yet found a good solution. Have not yet settled internationally.
As an emerging concept, the industry’s low-carbon standards are more difficult than in the international community recognized by the British Standards Institute is developing a normative?? PAS (carbon emissions).
British Standards Institution in 2009, the energy released Management System standards that can effectively help enterprises to improve Energy Efficiency and reduce greenhouse gas (GHG) emissions, lower energy costs. October 2008, the British Standards Institute released the world’s first standard product carbon footprint?? “PAS2050: 2008 goods and services in life cycle assessment of greenhouse gas emissions standard.”
Was not until March 1 this year, China’s Environmental Protection Department of Environment and Development Centre was signed with the British Standards Institution certified low-carbon products Cooperation Memorandum. According to this memorandum, the Department of Environment and Development Centre will be environmentally friendly and carried out jointly by the British Standards Institute as the main target of greenhouse gas emissions related work, including product certification jointly promote low carbon research.
Biggest appeal is that the standard reached by consensus, once introduced you to win the support of all sectors and use of a low carbon economy. China Building Materials Circulation Association Meng Guoqiang hope that “future release of this certification system will manage the entire process of building materials, a full range of authentication, and access to international mutual recognition.” Low Carbon Building Standards
But as environmental certification system, as not all countries are based on the same scale, so also the deposit certificate qualification differences, the parties need to consult with the international consensus. This process is very long, and the United Nations Industrial Development of China Building Materials Circulation Association supervision and management of international environmental resource agencies in the United States to be held at the end of 2010 the International Forum of Low Carbon Building, or can this be promoted.
