Decarbonization: From Strategy to Action in 3 Steps

How Digital Models, Real-time Insights, and Proven Tools are Balancing Carbon with Capacity

The refinery of the future isn’t a rebuild. Rather it’s a smarter version of what you already run. Today’s leaders aren’t just upgrading equipment. They’re rethinking how every system runs to power smarter, cleaner, and more connected operations.

But as margins shrink and environmental stakes rise, the question remains: how do you reach net zero targets without disrupting production?

The answer isn’t a single technology.  It’s a system built on smart tools, digital insights, and scalable strategies. In the race to decarbonize, success won’t come from having the newest equipment. It will come from those who turn knowledge into action.

By uniting simulation, strategy, and digital execution, refiners can drive positive results while preparing for future challenges.

How to Decarbonize Without Derailing Performance

Rather than aiming for perfection, leading refiners are actively driving progress. They’re taking action with the resources they already have and focusing on strategic upgrades that build momentum step-by-step. Here’s how:

1. Start with a Smart Model

To move fast, you need clarity and that starts with a single source of truth. Figure 1 shows the Integrated Process, Energy, Emissions & Economics Model (IP3EM) that gives you a consistent view of carbon intensity, process choices, and site-wide performance. This model lets you weigh options, test ideas, and tweak your operations for peak performance. This approach lays the groundwork to plan strategies and monitor operations in real time.

Why it works

  • Links energy use and emissions with profit
  • Models future scenarios with operations
  • Turns strategies into action - starting from design to daily decisions

2. Make the Invisible Visible

Digital twins act as real-time replicas of your process units, energy systems, and emissions profiles. These virtual watchdogs never rest. They catch inefficiencies, predict failures, and help operators fix issues before problems escalate.

Where they deliver:

  • Cut unplanned downtime by up to 20%
  • Reduce Scope 1 and 2 emissions by optimizing energy use
  • Keep systems running while making sustainability progress

3. Prioritize Tech That Pays Off

Start with what works. Tools such as energy management systems, emissions trackers, and automated reporting aren’t flashy, but they amplify your impact, as shown in Figure 2. Once you have the basics, then add advanced technologies like carbon capture and clean hydrogen.

Start with tools that move the needle:

  • Plug leaks, monitor combustion, upgrade infrastructure
  • Integrate CCS where feasible with robust modeling
  • Use automation and analytics to prioritize what’s working
