Human activities and industrialization are responsible for the increased amount of greenhouse gases (GHG), rising the global temperature and thus causing global warming. The innovation of nanocellulose as one of the most promising nature-based nanomaterials has driven the development of advanced materials in myriad fields, offering benefits for the remediation of greenhouse effects due to multifunctional characteristics and extraordinary properties. This includes the reduced usage of energy, leading to the significant reduction of GHGs and creating a new generation of membranes for capturing GHGs. Nanocellulose used in automotive parts offers a lower density, thus reducing fuel consumption and CO 2 release. It is also known as an insulating agent to reduce thermal conductivity by 30%, leading to lower energy usage. Membranes containing nanocellulose increase the permeation and selectivity for CO 2 capture at up to 65% and 80%, respectively. In this chapter, the magnificent use of cellulosic nanomaterial in GHG reduction is discussed and elaborated in detail.
