Japan launches its carbon market: paper tiger or real solution?

Published on May 18, 2026 | Translated from Spanish

Japan has launched a new emissions trading program, seeking to position itself in the climate fight. The initiative is met with caution: while some see it as a necessary step, others point out that the proposed limits are unambitious and the control mechanisms are weak. The fear is that it will end up being more of a political gesture than an effective tool.

The technical challenge of measuring and verifying carbon reductions 🔍

The system relies on the allocation of emission rights and the possibility of trading them. For it to work, a robust monitoring infrastructure is required to prevent fraud and ensure that each ton of CO2 accounted for is real. However, the lack of unified standards and the reliance on self-reported data from companies raise doubts about the transparency and real effectiveness of the mechanism.

Japan's carbon market: green smoke with a smell of defeat 💨

It seems Japan has discovered the magic formula: selling permits to pollute, but without tightening the screws too much on anyone. It's like putting a no smoking sign on a forest fire. Companies can breathe easy, as the new system, apparently, allows them to continue emitting with a clear conscience... and a signed piece of paper. All very eco-friendly, as long as you don't look at the sky.
