Why Rising US Emissions Reinforce the Importance of Measurement

This article responds to recent reporting by BBC News on the rise in US greenhouse gas emissions in 2025

After two years of decline, US greenhouse gas emissions increased again in 2025. A colder-than-average start to the year, combined with rapidly growing electricity demand from data centres and cryptocurrency operations, placed renewed pressure on the energy system. Coal and gas use both rose, outweighing continued growth in renewables and pushing overall emissions higher.

While much of the public debate focuses on fuels and policy, this shift also highlights a less visible but critical factor: measurement. Every change in emissions, energy use or efficiency is ultimately derived from data. Without accurate testing and monitoring, it is impossible to fully understand what is happening within the energy system or respond effectively.

Demand growth makes accurate testing essential

Rising electricity demand is no longer a short-term anomaly. Large, constant loads from data centres, increased heating needs during colder periods and ongoing electrification are reshaping how grids operate. To meet this demand, operators increasingly rely on detailed load analysis, power quality testing and real-time monitoring to balance reliability, cost and emissions.

When demand spikes, even small inefficiencies can result in significant additional fuel use. Accurate electrical testing helps identify losses, validate performance and ensure infrastructure is operating as intended.

Emissions data depends on underlying measurements

Emissions reporting is built on a foundation of measurements: fuel flows, combustion efficiency, electrical output and consumption. If those inputs are inaccurate, the resulting emissions figures are unreliable. As scrutiny from regulators, investors and customers increases, organisations must have confidence in the data they report.

This places greater importance on well-maintained, calibrated instruments, from electrical analysers to gas and thermal testing equipment. Measurement accuracy is no longer just a technical concern; it is central to compliance and credibility.

Efficiency, electrification and ongoing monitoring

Growth in data centres and electric transport illustrates another key trend: the need for continuous monitoring rather than one-off tests. Facilities operating around the clock depend on long-term measurement stability to optimise efficiency and avoid unnecessary energy use.

As energy systems become more complex, reliable test and measurement underpins every effort to control emissions, improve efficiency and plan future investment. The rise in emissions during 2025 serves as a reminder that meaningful progress depends not only on cleaner technologies, but on the quality of the data used to manage them.
