The GHG Protocol’s public consultation on Scope 2 (1) has triggered a wave of reactions. Most focus on the visible changes: hourly matching, stricter deliverability rules, more granular emission factors. These updates are often framed as a technical refinement of carbon accounting, aimed at improving accuracy and reducing greenwashing.
That reading is only partially correct.
What is unfolding is not just a methodological update. It reflects a deeper shift in how electricity consumption is expected to relate to the power system. Scope 2 is moving closer to how electricity actually operates: in time, in space, and under constraint. This evolution has implications that go well beyond reporting.
The real question is not only whether organizations can calculate emissions more precisely. It is whether they are prepared to operate in an electricity system that is becoming more dynamic, more local, and increasingly driven by renewable production.
Hourly matching and deliverability requirements are built on a simple and intuitive idea: emissions are lower when electricity is consumed at the same time and place as low-carbon generation. The GHG Protocol consultation takes important steps in that direction, by encouraging a closer alignment between electricity consumption and the physical operation of power systems.
This evolution reflects a broader shift in electricity systems themselves. As renewable generation grows, electricity becomes more variable over time and more differentiated across locations. Periods of abundant, low-cost renewable production coexist with moments where supply is more constrained and carbon-intensive. In many organizations, however, electricity consumption patterns remain largely static over time. Loads are monitored and reported, but rarely steered to reflect changes in renewable availability or local grid conditions. Consumption patterns are often inherited from past operational constraints, rather than adapted to the new dynamics of electricity systems.
As a result, Scope 2 accounting is becoming increasingly granular and time-aware, while electricity demand itself is still only loosely connected to these evolving signals. The challenge ahead is not only to measure emissions more precisely, but to create price signals to align consumption with a system shaped by the rise of low-carbon, variable electricity.
Another important shift in the consultation is the explicit prioritization of spatial granularity. When choosing emission factors, organizations are encouraged to rely on more local data, even if it is less temporally precise, rather than broad national averages.
This reflects a physical reality of electricity systems. Today, decarbonization challenges are not just national. They are also local.
Congestion on distribution networks, renewable curtailment in specific zones, and sharp variations in carbon intensity driven by local supply-demand imbalances are becoming common. These effects are largely invisible in national or regional averages, yet they are where emissions are actually determined.As renewable penetration increases, carbon intensity becomes increasingly uneven across both time and space. Acting on average grid signals smooths out exactly the information that would allow organizations to align their consumption with low-carbon electricity when and where it is available.
Granular data is necessary, but it is not sufficient.
In many discussions, flexibility is still understood as the ability to reduce or interrupt consumption at certain times. While this is one form of flexibility, it is only part of the picture. In electricity systems with growing renewable generation, another dimension becomes just as important: the ability to increase consumption when low-carbon electricity is locally abundant.
In this context, flexibility means piloting demand to follow renewable production. It means shifting energy-intensive activities, digital workloads, or industrial processes toward periods of high local renewable output, rather than simply avoiding peaks.
This type of flexibility turns carbon signals into operational opportunities. It allows organizations to consume more electricity when it is cleaner and cheaper, helping the grid absorb renewable generation while reducing emissions at the same time.
Without this operational layer, Scope 2 risks becoming increasingly precise in its accounting, while remaining disconnected from the decisions that actually shape emissions on the grid.
Electricity systems are evolving toward greater variability, stronger local constraints, and increasing reliance on renewable generation. Scope 2 reform is one of the first accounting frameworks to reflect this evolution, but it will not be the last.
Organizations that understand how electricity systems are changing, and start aligning their demand accordingly, can act today. They can reduce emissions, benefit financially from periods of low-cost renewable electricity, and build capabilities to increase their competitiveness.
The transition toward more flexible, better-aligned electricity demand is not a distant future requirement. It is already underway. The opportunity lies in achieving this transition today, for a long-term competitive advantage.
