Green transition
is $10.3 trillion opportunity for the global economy by 2050, new report finds
Roberta Harrington in London
New green industries could be worth $10.3 trillion to the global economy by 2050, equivalent to 5.2% of global GDP that year, finds a new report by Arup and Oxford Economics.
The green transition is often seen as a cost, but the report demonstrates the substantial benefits and the need to move quickly to capture them.
Investment in green technologies, expertise and renewable energy sources is crucial to addressing urgent climate challenges, say the authors in Global Green Economy, Capturing the Opportunity.
“Transitioning to a green economy is an inevitable end game for all countries, and many have already started their journey,” notes the report.
The report highlights ways innovation and strategic policymaking can address existential issues for the planet in a way that also builds broad prosperity and social well-being. Climate change is clearly an existential issue, with even a 1.5-degree Celsius rise in average temperatures seen as leading to devastation.
"As economists, we have to be honest about the fact that mitigating climate change will be expensive," said Oxford Economics' chief executive, Adrian Cooper. "But the transition to a carbon-neutral global economy also presents compelling opportunities."
New green industries – carbon-neutral goods, such as renewable-energy facilities, as well as services – are an essential part of reaching the Paris Agreement net-zero target.
"This includes the direct contribution to GDP of electric vehicles manufacturing, renewable power generation, clean energy equipment manufacturing, renewable fuels and green finance; plus the activity supported across global supply chains," said the report.
Indeed, former Bank of England governor Mark Carney has said that a net-zero emissions future will allow banks, fund

managers and insurers to invest in private sector plans – and profit from the “greatest commercial opportunity of our time."
And a peer-reviewed study using probabilistic cost forecasts by University of Oxford researchers, published in 2022,
found that transitioning to a decarbonised energy system by mid-century could actually save the world at least $12 trillion, compared with a scenario in which current levels of fossil fuel use continue, says the study.
A decarbonised energy sector would not only result in lower energy system costs than a fossil fuel system – by ramping up solar, wind, batteries, electric vehicles (EVs) and clean fuels such as green hydrogen – but it would also provide more energy to the global economy and expand energy access to more people internationally.
“There is a pervasive misconception that switching to clean, green energy will be painful, costly and mean sacrifices for us all – but that’s just wrong,” said Professor Doyne Farmer, the mathematics professor who led the research at the Institute for New Economic Thinking at the Oxford Martin School.
Oxford Economics even found that a failure to act could dent global GDP by some 5% by mid-century. In 2021, the researchers estimated that the cost of weather-related interruptions to economic activity had already reached $233bn.
"This report shows the green transition is not a burden on the global economy, but a substantial opportunity to bring about a greater and more inclusive prosperity," said Arup’s global strategy skills leader, Bryce Richard.
Meanwhile, a second report by Arup and Oxford Economics issued the same day on carbon prices found that they must rise higher as climate ambitions rise.
While carbon prices historically have been low and limited, this should change with rising climate ambitions, say the researchers. Countries with established carbon markets and ambitious climate agendas will take the lead, they continued.
