A programme to expand energy conservation and renewable energy supply in the European Union could create one to two million new, full-time jobs. Investments in mass transit systems also have significant direct employment effects and reduce transport costs for poor households. Expanding public urban transit systems can create 2.5 to 4.1 secondary manufacturing jobs per direct job created. More than 3.8 million jobs could be created globally through the production of vehicles with high fuel efficiency, hybrid and alternative fuel use and low-emission technologies, and up to 19 million additional ancillary jobs worldwide in fuel refining and distribution, sales, repairs and services. At least 1.2 million jobs worldwide are involved in biofuel production, but global expansion of next-generation feedstocks could easily yield 10 million jobs or more.
