Green Building Councils, which are members of the WorldGBC global network, develop and administer many of the world’s ratings tools. By 2016, 1.04 billion square metres of green building space (an area 10 times the size of Paris) had been certified around the world through member Green Building Councils.
WorldGBC recognises the power that rating tools have had in transforming the sustainability of building and firmly supports their use. We recognise that every rating tool is different, and that the member Green Building Council in a given country is best-placed to develop or select a rating tool that is best suited to their particular market. WorldGBC therefore takes a neutral approach to individual rating tools and does not advocate the use of one specific tool over another.
However, with the widespread use of rating tools around the world, WorldGBC believes that each green building rating tool must be meet quality standards. In 2015, WorldGBC published the Quality Assurance Guide for Green Building Rating Tools – a step by step to guide for the operators of new, emerging and established rating tools to ensure that their development and implementation is robust, transparent and to a good standard.
