GB/T 46878-2025 Active

a) Proposes requirements and recommendations for the geological storage of carbon dioxide, with the aim of promoting the economical, safe, and long-term storage of carbon dioxide, and minimizing the risks to the environment, natural resources, and human health;
b) Applies to geological storage in porous and permeable reservoirs on land and at sea, including oil and gas reservoirs. The injected carbon dioxide stream is not used for oil and gas production or for storage related to carbon dioxide enhanced oil recovery;
c) Includes site screening and selection, characterization, design and development, operation of storage sites, and preparation for site closure;
d) Recognizes that the siting and management of each project are unique, and inherent technical risks and uncertainties will be addressed based on the specific circumstances of each site;
e) Confirms that regulatory approval and permits are required throughout the project lifecycle (including the closure phase), although this document does not include the permit process;
f) Provides requirements and recommendations for the establishment of a management system, community and other stakeholder engagement, risk assessment, risk management, and risk communication;
g) Does not apply to modify, interpret, or replace any national or international regulations, treaties, protocols, or instruments applicable to the activities described in this document;
h) Does not apply to modify any property rights or interests (including mining rights) on the surface or underground, or any existing commercial contracts or agreements related to such property.
The lifecycle of a carbon dioxide geological storage project encompasses all aspects, periods, and stages of the project, from pre-project activities (including site screening, selection, characterization, assessment, engineering, permitting, and construction) to the start of injection operations and until injection c
