AIR EMISSIONS MANAGEMENT · ERM IMPLEMENTATION PARTNER

THE CONTEXT

Chevron

A global energy supermajor with complex operations

Managing air emissions across multiple business units meant complying with Title V permits and EPA GHG reporting – each with different calculation methods. A patchwork of legacy systems from past acquisitions made reporting unreliable and extremely resource-intensive.

THE CHALLENGE

Consistency across complex reporting programs

Air permits, Title V obligations and the U.S. Greenhouse Gas Reporting Program require different calculations. Across many facilities, manual processes made emissions data 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 to modify calculations in-house.

“We were a SharePoint, Excel, shared network drive nightmare. Information was everywhere, from filing cabinets to storing it online,” Bryn explains.

This chaos was compounded by external factors

Separate reporting methods and requirements

Multi-step reports and manual data work

Black-box calculations with limited audit traceability

All of this created what Bryn describes as

“a mismatch of information all over the place.”

THE PROBLEM

When emissions data stays fragmented

Patched-together systems were costly to maintain. Teams saw final totals but could not trace how calculations were made.

A black box with no way to trace calculations

A black box

Vender software seemed like a black box, making auditing extremely difficult. Teams couldn’t show how calculations were made end-to-end: they had final numbers but couldn’t explain them. The lack of transparency meant no corporate insight into what was happening at scale. Muti-step processes for each report consumed enormous resources.

THE APPROACH

Unified, efficient and audit-ready

Cority stood out because it's a true SaaS platform with scheduled updates that don't require service projects and configuration tools enabling in-house adjustments. This means lower maintenance costs and no risk of going out of date. ERM brought proven methodology and data-migration expertise to map existing data seamlessly into the new Cority system for the longest lookback possible.

After a failed air and greenhouse gas implementation with another vendor, the supermajor needed a solution it could trust globally. Following detailed evaluation, Cority emerged as the clear choice, selected for handling complex permits and calculations with the goal of automating reporting and improving corporate oversight.

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-migration methods and a long-standing relationship.

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.

So they started by addressing their emissions control challenges through these five foundational implementation steps.

Enable in-house changes and reporting

In roughly two and a half years, the company rolled out global GHG tracking and reporting. Its teams now have a unified view of emissions data.

THE OUTCOME

A clearer view of emissions worldwide

The global system gives teams more consistent data, automated calculations and easier access to reports across the business.

Ergonomics

Global GHG tracking and reporting in one configurable system

“make a correction, and it's immediately available for re-reporting”

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 and analyzing emissions data.

GHG data visible across a business unit and the corporation.

More accurate and reliable reporting.

Dashboards and compliance reports easier to share with leaders.

A global, no-code tool teams can configure in-house.

Now the supermajor measures granular emissions data, automates complex calculations and accesses intuitive reporting. It remains audit-ready across facilities with one unified platform. As the organization grows, teams are confident the solution will evolve alongside them.

"you need to plan for the complexity that innately happens in your business."
