A dietitian has qualifications in nutrition and dietetics and applies the science of food and nutrition to improve the health of individuals, groups, and communities. The Registered Dietitian (RD) credential has gained recognition over the years for its expertise. The accreditation systems were developed and have been used to ensure quality of this profession. Accreditation systems set standards for academic and professional training in nutrition and dietetics and reflect current research-based information. The purpose of this paper is to review a few countries that have a RD accreditation system including China and several other countries, e.g. the United States, Japan, and the United Kingdom. The aims are to introduce the newly established RD system in China and to compare the differences among the countries' systems. [ABSTRACT FROM AUTHOR]

Buildings consume large amounts of energy and resources and have a significant impact on environment. In 2010 buildings accounted for 32% of total global final energy use and 19% of energy-related GHG emissions. This energy use and related emissions may double or potentially even triple by mid-century. China is the world's largest energy consumer and CO 2 emitter. With the process of urbanization, China has been entering into a period of great prosperity for construction, about 1.6–2.0 billion m 2 buildings are constructed each year, which accounts for about 40% of the world's total new buildings. It is predicted that China’s building energy use and related emissions will continue to increase over the next 15 years. Therefore, promoting green building development has become an urgent issue in China. However, green building is a highly complicated system engineering, its promotion needs evaluation standards as technical support. Many countries had issued a series of green building evaluation standards since 1990. Currently, there are some representative green building assessment schemes. Code for Sustainable Homes (CSH) has been fully implemented as the national authoritative standard of the UK since 2010. Leadership in Energy and Environmental Design (LEED) developed by the USA, was revised and updated regularly with the latest version issued in 2013. China enacted its national evaluation standard for green building in 2006, and revised the standard in 2014. Based on introducing the latest evaluation standards for green buildings in China, Britain and United States, the paper compared these standards from 5 aspects including energy-saving, water-saving, material-saving, site selection and the outdoor and indoor environmental quality. The comparison mainly focuses on evaluation methods and evaluation indicators in the three standard systems. Besides, the characteristics of each standard system were summarized and some suggestions for improving China’s evaluation standard for green building were proposed. [ABSTRACT FROM AUTHOR]
