Tripling the world's renewable power capacity, cutting emissions and the Global Cooling Pledge are just some of the matters discussed and agreed upon by many officials at UN's COP28 climate summit. But without skilled workforce for these domains, they might become a dream, rather than reality.

LinkedIn co-founder Allen Blue said for Euronews.green that we don't have much time left to fill the gap found within sustainability-focused jobs. "The interesting thing about green skills, though, is that they are they're actually much more broadly distributed than you might consider", he said.

He also believes that it's not just sustainability-born jobs that matter, but also some existing ones, in fact over 50% of them, will likely include at least a green skill in the future. Also, LinkedIn officials say that green jobs are experiencing a higher interest from companies around the world, around 25% higher than jobs in any other industry.

These include EV manufacturing, battery development experts and green technology in general.

"But the issue is that the number of people with green skills remains about one in eight and one in nine in Europe", he continues, warning that only slight growths every year won't be enough to help keep up with demand.

"We saw it in the tech world, but it took 15 years to actually overcome that lack of engineers and I’m not sure we’ve even overcome it. I don’t think we have 15 years this time around", Blue added.

There are three big players in this sector, he believes, which will bring forward the green workforce of tomorrow. First are the employers, or companies that are setting the stage for things like green power, which is growing at a fast rate. Thus, companies installing solar panels, wind turbines or other sources of clean, renewable energy, will take on the task of training people.

Investors also play a major role, since they have to make sure that they offer financial support to companies that will be able to make profit from green-focused projects.

"When they see green projects, they frequently see risk. One of the forms that risk takes is a lack of a trained workforce to actually work on a project", Blue explained.

The third major player in the development of green workforce is actually the governance of every country. Blue says that Germany, Switzerland and Austria are often pointed to as being some of the best-prepared countries when it comes to training skilled green workers. But at the same time, he acknowledges that not all countries work the same and a different approach might be needed in some situations.

LinkedIn officials say that currently, about 90% of women lack green skills, while 16% of men have at least one, while there is a gender gap in the leadership positions, as well. Thus, governments must also make sure that the gap will be closed here, as well.

"There's been lots of commitment on the part of companies, individual companies among the ESG [Environmental, social and corporate governance] and so forth, to ensure that we have greater equality", LinkedIn's cofounder added.
