Global carbon emissions inventory
Using the World Resources Institute and the WBCSD’s GHG Protocol as guidance, we applied the operational control approach in defining our reporting boundaries. Operational control refers to the authority to develop and carry out the operating or HSE policies of an operation or a facility. Using this approach, our company accounts for 100 percent of emissions from operations for which we or our subsidiaries have operational control (including leased space and vehicles).
CH2M calculates emissions based on actual data, where available, and estimates emissions according to standard protocol guidelines where data are incomplete or unavailable. Conducting an inventory allows us to better understand emission sources and refine data collection processes. We anticipate continual enhancements as more staff become aware of the importance of keeping accurate data records for emission sources.
