Saudi Arabia has no dedicated framework climate-change act. Saudi Arabia's NDC, which the Kingdom itself titles its "Second Nationally Determined Contribution," was filed on 28 December 2025 and commits to reduce, avoid and remove 335 million tonnes of CO2eq annually by 2040 against a 2019 base year, a 20.5% progression over its 2021 NDC, pursued through its "Circular Carbon Economy" framing. Its carbon-market mechanism, the Greenhouse Gas Crediting and Offsetting Mechanism (GCOM), announced in October 2023 and launched in early 2024, is a voluntary, Article-6-aligned scheme traded through the Regional Voluntary Carbon Market Company (RVCMC), a joint venture of the Public Investment Fund and Tadawul established in October 2022.
