Two numbers are now inscribed in the statute books. They are 53 and 61. The National Assembly passed an amendment to the Framework Act on Carbon Neutrality and Green Growth for Coping with Climate Crisis at its plenary session on August 26, 2026, and the amended law sets the 2035 greenhouse gas reduction target in a range of 53-61%. The reduction pathway beyond 2030, which until now had remained in the realm of declarations and plans, has become a provision of law for the first time.
The starting point of this change was the Constitutional Court two years ago. In August 2024, the Court ruled the existing Carbon Neutrality Framework Act unconstitutional but kept it in force pending revision. The problem was that reduction targets for the period after 2031 were absent from the law. The Court held that if today's generation does not set targets, that share falls entirely on the next generation.
That blank has now been filled. Greenhouse gas reduction targets for the period after 2030 have been written into law and thereby become a legal obligation. A target written in a plan and a target written in a statutory provision carry different weights of binding force. Even if the government changes, even if industrial conditions swing, the provision remains.
The amended law also revised the procedure for setting targets. It newly establishes the Climate Science Committee, an independent advisory body, under the National Climate Crisis Response Committee. It will be composed of 15-20 members including a chair, with a two-year term for members. The body will handle matters such as setting mid- to long-term reduction targets and tracking progress on greenhouse gas reductions.
The reason for the Climate Science Committee's existence is clear. Reduction targets are set where the carbon budget presented by science meets the pace that politics can bear. Without a mechanism to keep scientific evidence permanently on that negotiating table, targets get pushed back every time. How much binding force will attach to the committee's recommendations, and when it will be launched, have not been made public.
On the day the law passed, environmental groups raised objections rather than applause. Opposition emerged to the effect that it was a sleight of hand passing the burden onto future generations. The Korean Federation for Environmental Movements demanded that the National Assembly promptly amend the Carbon Neutrality Act again to specify only a front-loaded reduction pathway. It also demanded the creation of regulatory and support policies to secure the reduction targets and pathway, along with the funding to back them.
This criticism is different in kind from a complaint that the target is too low. What divides the climate question is the shape of the curve that leads there. Even with the same 2035 target, a pathway that cuts steeply early on and a pathway that concentrates cuts later differ greatly in the cumulative emissions that accumulate in the atmosphere. Reductions put off come back as a bill demanding a sharper transition in a shorter period.
Even so, it is hard to say this amendment is not an achievement. A state in which no target existed in law and a state in which a target exists but the pathway needs further refinement start from different lines. The minimum framework required by the Constitutional Court's ruling has been built, and the debate now shifts to what will be placed on top of that framework. If the Climate Science Committee plays its part, science will set the baseline of that debate.
What must be watched from here is when the Climate Science Committee actually opens its doors and with what authority it issues its first review, and which point within the 53-61% range the government adopts as its working target. Under the same statutory provision, 53% and 61% become the story of entirely different countries. When a public notice inviting comments on a local climate ordinance or a municipal reduction plan appears, leaving even a single line of comment becomes part of the pressure that decides which end of this range it tilts toward.
