The solar scorecard ranks global photovoltaic module manufactures on a range of environmental, sustainability and social justice factors. These encompass: product take back and recycling; worker health and safety issues at PV facilities and in the supply chain; chemical use and lifecycle analysis; and company disclosure statements.
With a score of 91, German manufacturer SolarWorld topped the rankings. Trina Solar came in a close second, with a score of 89. Abound Solar, First Solar and REC were all ranked third, with 87 points each.
Last year, Calyxo topped the 2010 SVTC scorecard, with 90 points (2011: 82). Meanwhile, SolarWorld received 88; Trina zero, Abound 63 and First Solar 67.
Of the top 10 manufacturers worldwide, Canadian Solar and Hanwa SolarOne received a score of zero, or "Rainy" this year, which means, says SVTC, that they "did not respond to the survey and are not transparent; its not clear if they are committed to sustainability and social justice."
Sharp and Suntech also received a score of zero, or "Rainy". In a note, SVTC says that they did contact the coalition and "worked to have a constructive dialogue, but did not complete the survey."
Key findings from the scorecard include:
