stressed that achieving carbon peaking and carbon neutrality is an extensive and profound economic and social systemic change, and carbon peaking and carbon neutrality should be included in the overall layout of ecological civilization construction. The goal of "carbon peaking and carbon neutrality" has been established, and low-carbon design and green design have become an important way for designers of environmental design directions to achieve the goal of "carbon peaking and carbon neutrality". In order to promote the scientific development of low‐carbon concept and realize the green transformation of environmental design, the concept and connotation of low‐carbon design are deeply analyzed, based on the low‐carbon design concept, starting from the two aspects of enhancing carbon sequestration and oxygen release capacity and reducing carbon emissions, and analyzing the principles and applications of low‐carbon concepts in indoor and outdoor design.
