A patchwork of legacysystems from past acquisitions made reporting unreliable and extremely resource-intensive. ## Challenge ###### THE CHALLENGE ###### Consistency across complex reporting programs ###### Air permits, Title Vobligationsand the U.S. Greenhouse Gas Reporting Program require different calculations. Across many facilities, manual processes madeemissionsdata difficult to reconcile. ###### "To be able to audit, to be able to show to themselves or to a regulator, this is how we're doing our calculation from beginning to end, was an intensely manual process." - EHS Manager ###### Before Cority, business units relied on a patchwork of software and spreadsheets.Producing a report took multiple steps, and teams struggled tomodifycalculations in-house. ###### This chaos was compounded by external factors ###### “We were a SharePoint, Excel, shared network drive nightmare. Information was everywhere, from filing cabinets to storing it online,” Bryn explains. Black-box calculations with limited audit traceability Multi-step reports and manual data work Separate reporting methods and requirements ###### All of this created what Bryn describes as ###### “a mismatch of information all over the place.” ## Problem ###### THE PROBLEM ###### When emissions data stays fragmented ###### Patched-together systems were costly tomaintain. Teams saw final totals but could not trace how calculations were made. ###### A black box with no way to trace calculations #### A black box ###### Vendersoftware seemed like a black box, making auditing extremely difficult. Teamscouldn’tshow how calculations were made end-to-end: they had final numbers butcouldn’texplain them. The lack of transparency meant no corporate insight into what was happeningatscale. Muti-step processes for each report consumed enormous resources. ## Approach ###### THE APPROACH ###### Unified,efficientand audit-ready ###### After a failed air and greenhouse gas implementation with another vendor, the supermajor needed a solution it could trust globally. Following detailed evaluation, Corityemergedas theclear choice, selected for handling complex permits and calculations with the goal of automating reporting and improving corporate oversight. ###### Cority stood out becauseit'sa true SaaS platform with scheduled updates thatdon'trequire service projects and configuration tools enabling in-house adjustments. This means lower maintenance costs and no risk of going out of date. ERM brought provenmethodologyand data-migrationexpertiseto map existing data seamlessly into the new Cority system for the longest lookback possible. ## Approach 2 ###### A true SaaS platform ###### Scheduled updates and no-code configuration tools keep the system current and less costly to maintain. ###### A trusted partner ###### ERM brought regulatory expertise, data-migrationmethodsand a long-standing relationship. ## Transformation ###### THE TRANSFORMATION ###### From scattered tools to global GHG reporting ###### Cority and ERM took a staged approach to reduce implementation risk and ###### bring emissions data together. ###### Sothey started by addressing their emissions control challenges through these five foundational implementation steps. ###### Evaluate air and GHG system needs ###### 01 / ###### Map existing facility data ###### 02 / ###### Configure complex calculations ###### 03 / ###### Stage the global rollout ###### 04 / ###### Enable in-house changes and reporting ###### 05 / ###### Inroughly twoand a half years, the company rolled out global GHG tracking and reporting. Its teams now have a unified view of emissions data. ## Outcome ###### THE OUTCOME ###### A clearer view of emissions worldwide ###### The global system gives teams more consistent data, automatedcalculationsand easier access to reports across the business. ###### “makea correction, and it's immediately available for re-reporting” ###### Ergonomics ###### Global GHG tracking and reporting in one configurable system ###### But the successes don’t end there. Since rolling out Cority at Chevron, the team has achieved the following wins: A fraction of the time spent collecting andanalyzing emissionsdata. GHG data visible across a business unit and the corporation. Moreaccurateand reliable reporting. Dashboards and compliancereportseasierto share with leaders. A global, no-codetoolteams can configure in-house. ## Quote ###### Now the supermajor measures granular emissions data, automates complex calculations and accesses intuitive reporting. Itremainsaudit-ready across facilities with one unified platform. As the organization grows, teams are confident the solution will evolve alongside them. ###### "youneed to plan for the complexity that innately happens in your business." ## Cortex AI ###### Ready to bring air emissions data together?
