We report our sustainability performance annually, with our reporting period encompassing a calendar year. In this report, we include for the first time sustainability performance data for Thomas & Betts, a company acquired during 2012. ABB completed a number of strategic acquisitions during 2013, the most significant of which was solar inverter maker, Power-One. Other acquisitions included Newron (building automation), ELBI Elektrik (low-voltage products), Los Gatos (measurement products) and Dynamotive (service for drives and motors). Sustainability reporting for these entities will be included in our 2014 report. There were no significant changes during 2013 in the scope, boundary or measurement methods applied in the report.
