Laszlo Varro, the chief economist of the Paris-based International Energy Agency (IEA), is joining Anglo-Dutch oil and gas giant Shell.

Varro confirmed the move on his LinkedIn Page.

It comes weeks after the IEA published a bombshell report in which it said there was no need for investment in new fossil fuel developments if the world wants to tackle global warming effectively.

Varro joined the IEA in 2011 and became the agency's chief economist in 2016.

It is understood he will replace company veteran Jeremy Bentham as head of Shell’s "Scenarios" team, which produces forecasts for management.

Bentham is retiring after 41 years at the supermajor.

In his LinkedIn post, Varro said: "All good things come to an end eventually. After a beautiful decade at the IEA mapping the road for the energy system it is time to don a hard hat, grab the steel and return to the industry to try to build it.

"By joining Shell I enter a company that embarked on a transformation deeper and more profound than anything in its long history."

Varro said the "conclusion of the journey will be a Shell that is an indispensable pillar of a secure and efficient net zero energy system, working with consumers and governments, supplying low carbon energy in various physical forms and operating carbon removal facilities".

He added: "A lot of hard work and no doubt tough challenges are ahead, but Shell has amazing technical capabilities and even more importantly amazing people whom I’m greatly honored to join. Let the adventure begin."

The IEA report — "Net Zero by 2050" — concluded a global energy sector with net-zero emissions is achievable within 30 years, but warned that the pathway is “narrow” and will require an “unprecedented transformation of how energy is produced, transported and used globally”.

Shell has not commented on the appointment.

Shell aims to increase its low-carbon energy investments in the coming years, but a big proportion of its spending will be tied to oil and gas.
