Leading Countries Prepared For The Green Tech Transition

(Source: statista.com)

The United Nations Trade and Development Council (UNCTAD) ranked 166 countries according to how prepared they are to adopt frontier technologies deeply relevant for the green-tech transition.
The ranking was based on five indicators: ICT, skills, industry, R&D, and finance. Accordingly, a final score was allocated to each country by adding up the ranks of each of these indicators.
Countries with the highest scores were the United States, Sweden, Singapore, Switzerland, and the Netherlands; essentially, they were the most ready to utilise or adapt to frontier technologies.
At the opposite end of the spectrum, very poorly, Guinea, the Democratic Republic of Congo, Gambia, Guinea-Bissau, and South Sudan were the least prepared.
The findings highlight a clear divide between high-income and lower-income nations, with regions such as Latin America, the Caribbean, and sub-Saharan Africa being the least ready to take advantage of these technologies and thus potentially being deprived of new avenues.
China, despite being top in the world in developing and innovating frontier technologies, lagged far behind in 35th place.
This was mainly due to differences in internet coverage and broadband speeds across urban and rural areas.
Other BRICS members also tend to have very low rankings, ranking Brazil 40th, India 46th, and South Africa 56th.
However, some Asian countries did better than expected. Vietnam came 45th, the Philippines 57th, and India ranked 55th in one segment of the assessment.
Compared to rankings calculated based on per capita income, India did very well, coming in 67 places higher than expected.
According to UNCTAD, the good showing was attributed to investments in infrastructure, stronger technical skills, and a business environment conducive to growth.

According to UNCTAD, the U.S., Sweden, Singapore, Switzerland, and the Netherlands prevail as the best frontier-technology-adapting nations.
These technologies themselves will generously intervene in the green technology transition. UNCTAD looked at 166 countries with five indicators: ICT, skills, industry, R&D, and finance.
The rankings on each indicator were added to form a consolidated score. For instance, the U.S. ranked 2nd for R&D, 11th for ICT, 18th for skills, 16th for industry, and 2nd for finance, making its total 49.
Moving to the other extreme, Guinea, the Democratic Republic of Congo, Gambia, Guinea-Bissau, and South Sudan rank the lowest by consistently sitting in consistently poor positions across the five indicators.
The findings highlight a clear divide between high-income and lower-income nations, with regions such as Latin America, the Caribbean, and sub-Saharan Africa being the least ready to take advantage of these technologies, leaving them at risk of missing out on new opportunities.
China, despite being a global leader in producing and innovating frontier technologies, ranked lower than expected at 35th place.
The main reasons were disparities in internet coverage and broadband speeds between urban and rural areas.
Other BRICS members also placed relatively low, with Brazil ranked 40th, India 46th, and South Africa 56th.
Some Asian countries, however, exceeded expectations. Vietnam ranked 45th, the Philippines 57th, and India 55th in one part of the assessment.
India performed particularly well, placing 67 spots higher than expected. UNCTAD attributed this to increased investment in infrastructure, stronger technical skills, and a supportive business environment.

Top Export Of Green Tech From Developed/Developing Nations

(Source: statista.com)

According to the United Nations, many Global South countries may find themselves second in the green technology transition unless urgent action is taken by national governments as well as the international community.
These technologies are now fast-growing and will develop into a massive industry. The global market for these technologies was worth US$1.5 trillion in 2020, with projections to reach up to US$9.5 trillion in 2030.
Back in 2018, rich and poor countries were almost equal in how much they exported in green technologies, around US$60 billion each.
But by 2021, developed nations had surged ahead, exporting US$156 billion worth of green technologies, while developing countries only managed US$75 billion.
Rising disparities are shown here; the longer these persist, the greater will be the difficulty for poorer developing countries to catch up.
Therefore, UNCTAD is pressing developing countries to undertake policy measures favouring green and high-tech industries, strengthen science and technical skill-sets, improve internet and technological infrastructure, and bridge the urban and rural divide.
Richer nations are requested to align their trade rules with the objectives of the Paris Agreement on climate change.
