lead to a more accurate basis for indirect
emissions reporting.
Bringing it all together. Alone, these
capabilities are insufficient: they must
work together towards the net-zero target
utilizing a plan-do-check-act (PDCA)
framework, as shown in FIG. 5, driving
iterative and continuous improvement.
Driving net-zero targets requires crossfunctional
collaboration across the value
chain, so it is essential to embed the
systems and capabilities into the entire
supply chain operations. One way is to
leverage existing systems, processes and
standards already in place. Few such systems
to consider are:
* International Organization for
Standardization (ISO) 50001
for energy management provides
a PDCA-based framework that
can be extended to emissions
management to guide the journey
to net-zero.
* ISO 14000 family of standards,
including ISO 14001

(Environmental Management
Systems) and ISO 14064
(Greenhouse Gases).
The capabilities discussed here-the
use of a digital twin to calculate a rigorous,
engineering-based view of energy
and emissions reduction potential; and
unified production and emissions accounting
with a more detailed analysis
of fuel and loss-enable a more robust
adoption of these systems and standards,
overcoming traditional limitations seen
in typical deployment (these functions
have traditionally been carried out using
an array of user-specific Excel calculations).
A system and standard-based
approach where carbon-aware planning
and process digital
twin-based energy
and emissions management help set targets
and prioritize actions. Unified emissions
and production accounting enables
tracking, monitoring and reporting of
achievements against targets, and can
provide organizations a competitive advantage
on the journey to net-zero.
Energy companies must generate
objective targets for emissions reduction
and prioritize actions and initiatives
based on economics. The ability
to monitor and track their progress will
help them uncover a profitable path to
net-zero. Markets and shareholders will
reward companies that demonstrate this
capability earlier than others. Companies
interested in capturing this opportunity
should review their management
systems around energy and emissions
reporting and management and enhance
them by using systems and solutions for
carbon-aware planning, process digital
twin for energy and emissions management,
and unified production and emissions
accounting.
