What is the twin transition?
The twin transition, in EU policy language, describes two major transformations that must run in parallel: the green transition (the 2050 climate-neutrality goal) and the digital transition (the 2030 Digital Decade targets). The core idea is simple: without the green axis, digital investment is incomplete; without the digital axis, green targets cannot be measured.
The concept took shape with the 2019 European Green Deal and the Commission’s political guidelines, and was reinforced by the New Industrial Strategy, COM(2020) 102 (10 March 2020). That document states plainly that “the twin ecological and digital transitions will affect every part of our economy, society and industry.”
Why simultaneously? Synergy and tension
How does digital enable green? The European Environment Agency (EEA) describes three functions: (1) data generation — field measurement via IoT, sensors and satellites; (2) advanced analytics — pattern-finding and optimisation through AI; (3) operational action — applying that analysis across energy, production and logistics.
But there is another side. Digital has its own environmental footprint, and efficiency gains may not bring absolute resource reduction on their own — this is the rebound effect. The EEA and JRC are clear: benefits do not arrive automatically; proactive governance and explicit targets are required. Anyone serious about the twin transition must preserve this honesty.
The EU framework
The Joint Research Centre’s report “Towards a green and digital future” (JRC129319, EUR 31075 EN; with input from over 200 stakeholders) summarises the core finding: green and digital can reinforce each other, but are not automatically compatible — alignment takes deliberate design.
The Commission’s 2022 Strategic Foresight Report (COM(2022) 289, “Twinning the green and digital transitions”) shows the scale: information and communication technologies use roughly 5–9% of global electricity, and the twin transition is projected to require about €650 billion in additional annual investment.
The Industry 5.0 link
The twin transition becomes concrete in the European Commission’s Industry 5.0 vision. Complementing Industry 4.0, this framework rests on three pillars and gives the twin transition its human face:
01 Sustainability
Keeping production within planetary boundaries; circular and low-carbon.
02 Human-centricity
Using technology for workers’ well-being and skills, not to replace them.
03 Resilience
Flexible production that withstands crises, supply shocks and volatility.
What it means for Türkiye
For Türkiye, the twin transition is not an abstract EU concept but a concrete market condition. The CBAM definitive period began on 1 January 2026 and directly affects six carbon-intensive sectors. At the same time, digital support programmes (KOSGEB, Model Factory) and green-transition programmes complement one another. We gather these drivers, with sources, on the Why start now? page.
