By contrast, electrical and HVAC workers will likely need to attend accredited training programmes at community colleges or through their local trade union. For example, to support the transition to green jobs, in 2008 the Mechanical Contractors Association of Chicago established a green construction institute, to providing training to local building contractors, apprentices and journeyman of United Association of Pipe Fitters Local 597 (MCA Chicago, 2011). According to one analysis, 2 200 jobs will be created by full implementation of the retrofit programme called for by the Chicago Climate Action Plan (Schrock, 2009), but given that this is a small fraction of total construction employment in the region, and because there is currently a large volume of skilled trades people currently unemployed (CWIC-CJC, 2010), it is likely that current training programme will suffice.
