The debate, organised by the European Greens, sought to assess the state of play in the EU's drive to "green the economy," particularly as it relates to the creation of low-carbon jobs.
Former Socialist MEP Gyula Hegyi, introduced as 'Mr. Green Jobs' in EU Employment Commissioner László Andor's cabinet, refuted the notion that the green agenda would only create elite science and high-tech jobs.
Instead, he emphasised that workers from all skill levels would require retraining to adapt to the green era. "Green jobs will also mean low-skilled jobs, and millions of them," he claimed.
He cited as an example a major project in his home country Hungary – a canal which will link the Danube with another major river, providing agricultural irrigation and improved transport emissions. This project would require 100,000 workers to build, and 40,000 workers to maintain, he said.
The International Labour Organisation (ILO) definition is the ideal benchmark for how we should view green jobs, Hegyi said, adding that the promotion of low-skilled, low-carbon employment "can have a very important social function, particularly in a time of crisis".
No transformation without investment
The Commission official argued that if successfully promoted, the advent of the green jobs era in the EU could be compared to the advent of the computer era 20 years ago, in that scientists and tech experts will initially hold most of the knowledge, but it will rapidly become common currency among all citizens.
However, other participants at the debate cautioned that this hopeful scenario could only become reality if policymakers as well as big business leaders put their money where their mouth is.
German Green MEP Elisabeth Schroedter, who in April 2010 produced a draft report on the subject, argued that without significant investment in the "green transformation" of European industry and the retraining of European workers, more jobs would be lost than created.
This point was echoed from the industry perspective by Judith Kirton-Darling of the European Metalworkers Federation (EMF). "We have heard a lot of rhetoric about green jobs, but the lack of real investment worries us," she cautioned.
Kirton-Darling said that the scale of the transformation was "mind-boggling" and would fail without huge investment, specifying that many industrial players and trade unions favoured the introduction of so-called "green bonds" – Euro bonds earmarked for investment in green technology and training.
Hegyi, too, mentioned green bonds as a potential investment tool, and also drew attention to the new UK government's mooted green investment bank, which he viewed as a positive idea.
He concluded by arguing that both EU structural funds and the European Social Fund would have to play a part "if we are serious about greening our economy".
