Recognizing the critical importance of worldwide efforts to reduce greenhouse gas (GHG) emissions, CNA is reporting its GHG baseline emission inventory. This report summarizes CNA’s inventory of Scope 1 and 2 GHG emissions sources for calendar year 2022 and was prepared in accordance with The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard developed by the World Resources Institute and World Business Council for Sustainable Development.

CNA’s Scope 1 and 2 GHG emissions totaled 747.7 metric tons of CO2 equivalent and are summarized in Table 1. Scope 1 emissions are emissions from sources that CNA owns or controls. Scope 2 emissions (emissions that occur at sources owned or controlled by another organization) make up 99 percent of CNA’s GHG emissions and are the result of the electricity CNA consumes.
