In recent months a number of key unions representing workers in energy and transportation have joined TUED.
At its 5th Congress on May 22nd in Barcelona, the European Transport Workers Federation (ETF) Executive Committee voted to join TUED. According to ETF's General Secretary, Eduardo Chagas,
"TUED takes the same approach to energy as did the International Transport Workers Federation (ITF) at its World Congress in 2010. I was on the climate change committee that helped develop the 'Reduce, Shift, Improve' approach to fighting transport-related emissions and pollution. But without controlling the energy sector, it will be impossible to make transport truly low-carbon, healthy, and sustainable. ETF's joining TUED affirms the ITF's 'economy wide approach' to climate-related concerns."
The ETF represents more than 3.5 million transport workers from more than 230 transport unions and 41 European countries, in the following sectors: railways, road transport and logistics, maritime transport, inland waterways, civil aviation, ports & docks, tourism and fisheries.
Local 11 sees itself as part of a broader movement for "social justice, safe jobsites, training, green jobs and opportunity for all." The IBEW represents more than 700,000 workers, and seeks to organize all workers in the entire electrical industry in the United States and Canada, including all those in public utilities and electrical manufacturing, into local unions. Local 11's Business Manager Marvin Kropke said the local union's decision to join TUED came after the 2-day leadership retreat organized by TUED at Local 3 IBEW's Education and Cultural Center in Long Island. "Local 11 is progressive on energy issues, and the local has been pushing solar by way of Community Choice Aggregation (CCA) in the Los Angeles area," said Kropke. We are doing what we can, but we wanted to connect with others in progressive labor in the US and internationally."
From Norway, the 37,000 member Electricians and IT workers union EL og IT Forbundet also joined TUED and sent two national officers to TUED's first Europe-wide meeting in Geneva in June (report to follow).

The union represents workers in telecommunications, electrical engineering, hydroelectric power, and IT. According to the union's president, Jan Olav Anderson, "Norway's power system is mainly generated by large hydroelectric dams, but there are proposals to expand Norway's capacity so that we can export power elsewhere in Europe. Another major controversy is arctic exploration for oil. These are controversial issues and we joined TUED in order to be better connected to the Europe-wide and international debates on the future of energy."
