Green and STEM Jobs Surge as OECD Calls for Urgent Skills and Training Reform

A new OECD study finds that the green transition is rapidly transforming traditional jobs into more technology-driven roles, increasing demand for STEM, digital, and engineering skills across industries. The report warns that countries must modernise vocational education and apprenticeships to avoid major skill shortages in the emerging green economy.

A new OECD study has found that the shift toward cleaner energy and low-carbon industries is transforming labour markets much faster than many education systems can adapt. The report, prepared by researchers from the Organisation for Economic Co-operation and Development (OECD) and the Dresden University of Technology in Germany, examines how vocational education and training (VET) systems in Australia, Canada, and the United Kingdom are responding to the growing demand for green and STEM-related skills.

Using millions of online job advertisements collected through labour-market analytics company Lightcast, the study shows that green jobs are no longer limited to environmental sectors. They are now spreading across industries such as construction, transport, manufacturing, engineering, logistics, and digital services. According to the report, green occupations already account for around one-quarter of all job postings in Canada and more than one-fifth in Australia and the United Kingdom.

Traditional Trade Jobs Are Becoming More Technical

One of the report's strongest findings is that many traditional vocational occupations are becoming far more technology-driven. Electricians, automotive technicians, refrigeration mechanics, and construction workers are increasingly expected to work with advanced digital systems, renewable-energy technologies, electric vehicles, and energy-efficient equipment.

The OECD says this change is creating a strong overlap between green jobs and STEM fields such as science, technology, engineering, and mathematics. Nearly half of newly emerging green occupations in the United Kingdom are also classified as STEM jobs, with similar trends appearing in Australia and Canada.

As a result, vocational education systems are under pressure to modernise. The report argues that VET programmes can no longer focus only on practical trade skills. Workers now also need stronger foundations in mathematics, digital literacy, engineering concepts, and problem-solving to keep pace with rapidly changing technologies.

Employers Are Hiring for Skills, Not Just Degrees

The study also highlights a major shift in recruitment practices. Across all three countries, many employers no longer insist on formal educational qualifications when advertising green and STEM jobs. Instead, companies are increasingly looking for practical skills, industry certifications, online training, and relevant work experience.

This trend is especially visible in the United Kingdom, where skills-based hiring has expanded rapidly in sectors facing labour shortages and fast technological change. However, the report notes that formal qualifications still matter greatly in highly technical green occupations and advanced engineering roles.

Researchers say this shift means vocational systems must become more flexible. Short courses, modular qualifications, and targeted upskilling programmes could become increasingly important in helping workers move into green industries.

Apprenticeships Could Become a Key Green Workforce Pipeline

Apprenticeships are emerging as one of the most important routes into green employment, particularly in Canada. Nearly one-third of apprenticeship job postings are linked to green occupations, reflecting growing demand for skilled workers in renewable-energy infrastructure, electrical systems, and energy-efficient construction.

But the report warns that apprenticeship systems face serious challenges. Completion rates remain low in all three countries, with many apprentices leaving programmes because of poor working conditions, low wages, or weak career guidance. According to the OECD, improving apprenticeship quality and completion rates will be essential if countries want to avoid labour shortages in critical green sectors.

The report also highlights the role of school-based apprenticeships and pre-apprenticeship programmes in helping disadvantaged young people enter technical and green occupations. Such programmes could help ensure that the green transition creates opportunities rather than deepening inequality.

No Green Transition Without Skills Investment

The OECD concludes that the green transition is ultimately a skills transition. Cleaner technologies and climate investments alone will not be enough unless countries can also build a workforce capable of operating and maintaining those systems.

The report shows that each country has its own green-skills profile. Australia's transition is strongly linked to renewable-energy engineering and infrastructure projects. Canada relies heavily on transport systems and operational technical skills, while the United Kingdom has the most advanced demand for high-level engineering, automation, and electrical systems.

Because of these differences, the OECD argues there can be no single global approach to green skills training. Instead, vocational education systems must be tailored to national industries and labour-market needs.

The study sends a clear message to policymakers: the future of green economies will depend not only on investment in technology, but also on investment in workers, training systems, and modern vocational education.
