After all these years and despite so many accomplishments, measures that save energy remain U.S. climate policy’s bastard child.
Even defenders of energy efficiency sell it short. The latest instance was last Friday’s NY Times column, Give Me Laundry Liberty or Give Me Death!, by the paper’s resident polemicist, the economist Paul Krugman.
Electricity Savings’ top role in reducing electric-sector emissions is especially critical because no other sector (transport, industry, etc.) cut emissions more than marginally.
Krugman rightly savaged Congressional Republicans for contesting U.S. Energy Department efficiency standards for washing machines and other major energy-consuming appliances. His column reminds us that today’s G.O.P. never passes up an opportunity to force fossil fuels on the American public.
As Krugman noted, Republicans’ depiction of Democrats as enemies of freedom is exactly backwards: “Regulations ensuring that the appliances on offer are reasonably efficient reduce people’s cognitive burden — you might even say they increase our freedom,” by unshackling consumers from the task of weeding out inefficient (and expensive-to-run) appliances from efficient ones.
But consider what Nobel economics laureate Krugman left out: The only U.S. sector that has cut carbon emissions by more than token amounts since 2005 is electricity, furnishing a whopping 92 percent of the overall drop in emissions in 2023 since 2005. (See bar graph further below.) And energy savings, measured as kilowatt-hours that didn’t need to be generated because electricity savings curbed demand, accounted for 40 percent of electricity-sector carbon reductions — besting the 36 percent from power generators’ shift from coal to less-carbon-intensive fossil gas, and far surpassing the combined 24% share from growth in wind and solar electricity. (See pie-chart above. Details follow at end of post.)
Why are electricity savings undervalued?
Since 2005, the U.S. economy has grown by 40 percent in real (inflation-adjusted) terms. Yet over the same 18 years, U.S. electricity generation barely budged, rising just 5 percent. That is an immense change from mid-(20th)-century, when electricity usage typically grew each year by 6 or 7 percent, practically doubling every decade. This wrenching apart of electricity growth from economic growth has enabled the increased penetration of fossil gas-fired electricity and the rapid increase in wind and solar electricity to bite deeply into coal-fired power generation rather than simply add to it.
Yet energy savings are downgraded in energy and climate discourse. It’s not hard to see why.
First, energy saving is invisible. There are no ribbon-cuttings for energy-efficient buildings or appliances, no medals for low-energy lifestyles. Super-efficient houses or office buildings occasionally are singled out for praise, but what’s the visual — a low-electricity or gas bill? Or, worse, Jimmy Carter’s White House cardigan, which 1970s media held up for ridicule?
Second, saving energy lacks powerful lobbies. There’s no energy-saving counterpart to the American Gas Association, the American Wind Energy Association, the Solar Energy Industry Association, the National Coal Association, and certainly not the American Petroleum Institute, which was represented at the Mar-a-Lago dinner last week at which ex-president Trump pressed the fossil fuel industry for a billion dollars in campaign contributions. Only the American Council for an Energy-Efficient Economy and the Natural Resources Defense Council persistently advocate for energy effiicency, and they do so as tech experts and champions of the greater good rather than as arm-twisting lobbyists, and certainly not as bundlers of campaign cash.
Lime-green bars show CO2 emissions from electricity generation. The sole other sector with substantially lower 2023 emissions, “Other” Petroleum, shown in yellow, shrank due to natural gas’s increasing industrial-market share.
Energy efficiency and savings also suffer from a measurement problem. Implicit in measuring their climate contribution is a counterfactual: what would energy requirements and emissions have been without the energy savings?
For this post as well as predecessor posts in 2016 and 2020 I used as a baseline U.S. electricity generation if the 1975-2005 ratio between electricity growth and GDP growth had persisted. I think that was reasonable, but who’s to say? The avoided kWh’s I computed for the pie chart depend on a measuring convention that is subject to argument.
(Note that “offshoring” — the compositional shift of the U.S. economy toward services and away from manufacturing, with imports from China and other Asian countries furnishing the lost production — has also contributed to reducing the link between electricity and domestic economic activity; however, its numerical impact only accounts for a fraction of the flattening of U.S. electricity consumption over the paste two decades.)
Energy Efficiency’s Respect Deficit Is Consequential
Undervaluing energy efficiency means that energy-saving policy measures get short-changed. Efficiency standards for appliances, vehicles and buildings are insufficiently supported, enacted and enforced, leaving them vulnerable to being watered down or blocked altogether.
That’s the obvious part. More consequential is the cultural and political fallout. The short shrift accorded energy savings contributes to downplaying the demand side of energy and climate. This in turn has contributed to the unfortunate narrowcasting of climate campaigns to campaigns to block supply expansions. Measures that would curb consumption get disregarded, even though they are arguably more enduring and effective in curbing climate-damaging emissions than campaigns to halt drilling or pipelines, which largely relocate supply expansions elsewhere.
A major casualty of this narrowcasting is sidelining of carbon pricing as a serious policy contender. That’s not to say that the U.S. would necessarily have robust carbon pricing if energy savings were given their due. Rather, the marginalizing of energy savings and of carbon pricing are mutually reinforcing.
Part of the power of carbon taxing is that it operates on both the demand and supply sides of the fossil-fuel and emissions equation. (Another part is that carbon pricing complements virtually every other emissions-reducing policy or program.) Downgrading the demand aspect of our energy and climate miasma does a disservice to carbon pricing — and our climate.
Calculation Details
Calculations for this post were made in CTC’s carbon-tax model spreadsheet (2.2 MB downloadable Excel file). See Clean Electricity tab and Graphs tab. Pie-chart shares are derived by comparing 2023 and 2005 generation for solar (including distributed solar), wind and fossil gas and applying industry-average CO2 emission factors for coal and gas. Electricity-savings slice was computed by subtracting actual 2023 U.S. electricity generation from hypothetical 2023 generation if the average 1975-2005 ratio between electricity growth and GDP growth had continued through 2023, and then ascribing a per-kWh CO2 emission factor calculated as the mean of gas and coal CO2/kWh.
In crediting electricity with 92% of all 2005-2023 U.S. CO2 reductions (from fossil-fuel burning), I divided electricity-sector reductions of 983 million metric tons (“tonnes”) of CO2 by the total reduction of 1,064 million tonnes. However, the denominator is deflated by including “negative reductions” from passenger vehicles (14 million tonnes) and gas for industry (206). Even removing those sectors from the denominator, electricity accounted for 77% of total gross reductions (983 divided by 1,284). Note that these figures are shown in the Outcomes tab of CTC’s carbon-tax model.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.

Industries with the biggest nature footprints and what their decarbonisation looks like
A corporate carbon footprint is never just an accounting figure. It maps onto real ecosystems. Before a product leaves the factory gate, something on the ground has already paid the cost. A forest has been converted. A river has been depleted. A patch of savannah that was once home to dozens of species now grows a single crop in every direction.

Apple, Amazon Lead 60+ Firms to Ease Global Carbon Reporting Rules
More than 60 global companies, including Apple, Amazon, BYD, Salesforce, Mars, and Schneider Electric, are pushing back against proposed changes to global emissions reporting rules. The group is calling for more flexibility under the Greenhouse Gas Protocol (GHG Protocol), the most widely used framework for measuring corporate carbon footprints.
The companies submitted a joint statement asking that new requirements, especially those affecting Scope 2 emissions, remain optional rather than mandatory. Their letter stated:
“To drive critical climate progress, it’s imperative that we get this revision right. We strongly urge the GHGP to improve upon the existing guidance, but not stymie critical electricity decarbonization investments by mandating a change that fundamentally threatens participation in this voluntary market, which acts as the linchpin in decarbonization across nearly all sectors of the economy. The revised guidance must encourage more clean energy procurement and enable more impactful corporate action, not unintentionally discourage it.”
The debate comes at a critical time. Corporate climate disclosures now influence trillions of dollars in capital flows, while stricter reporting rules are being introduced across major economies.
The Rulebook for Carbon: What the GHG Protocol Is and Why It’s Being Updated
The Greenhouse Gas Protocol is the world’s most widely used system for measuring corporate emissions. It is used by over 90% of companies that report greenhouse gas data globally, making it the foundation of most climate disclosures.
It divides emissions into three categories:
- Scope 1: Direct emissions from operations
- Scope 2: Emissions from purchased electricity
- Scope 3: Emissions across the value chain

The current Scope 2 rules were introduced in 2015, but energy markets have changed since then. Renewable energy has expanded, and companies now play a major role in funding clean power.
Corporate buyers have already supported more than 100 gigawatts (GW) of renewable energy capacity globally through voluntary purchases. This shows how influential the current system has been.
The GHG Protocol is now updating its rules to improve accuracy and transparency. The revision process includes input from more than 45 experts across industry, government, and academia, reflecting its global importance.
Scope 2 Shake-Up: The Battle Over Real-Time Carbon Tracking
The proposed update would shift how companies report electricity emissions. Instead of using flexible systems like renewable energy certificates (RECs), companies would need to match their electricity use with clean energy that is:
- Generated at the same time, and
- Located in the same grid region.
This is known as “24/7” or hourly or real-time matching. It aims to reflect the actual impact of electricity use on the grid. Companies, including Apple and Amazon, say this shift could create challenges.

According to industry feedback, stricter rules could raise energy costs and limit access to renewable energy in some regions. It can also slow corporate investment in new clean energy projects.
The concern is that many markets do not yet have enough renewable supply for real-time matching. Infrastructure for tracking hourly emissions is also still developing.
This creates a key tension. The new rules could improve accuracy and reduce greenwashing. But they may also make it harder for companies to scale clean energy quickly.
The outcome will shape how companies measure emissions, invest in renewables, and meet net-zero targets in the years ahead.
Why More Than 60 Companies Oppose the Changes
The companies argue that stricter rules could slow climate progress rather than accelerate it. Their main concern is cost and feasibility. Many regions still lack enough renewable energy to support real-time matching. For global companies, aligning energy use across different grids is complex.
In their joint statement, the group warned that mandatory changes could:
- Increase electricity prices,
- Reduce participation in voluntary clean energy markets, and
- Slow investment in renewable energy projects.
They argue that current market-based systems, such as RECs, have helped scale clean energy quickly over the past decade. Removing flexibility could weaken that momentum.
This reflects a broader tension between accuracy and scalability in climate reporting.
Big Tech Pushback: Apple and Amazon’s Climate Progress
Despite their push for flexibility, both companies have made measurable progress on emissions reduction.
Apple reports that it has reduced its total greenhouse gas emissions by more than 60% compared to 2015 levels, even as revenue grew significantly. The company is targeting carbon neutrality across its entire value chain by 2030. It also reported that supplier renewable energy use helped avoid over 26 million metric tons of CO₂ emissions in 2025 alone.

In addition, about 30% of materials used in Apple products in 2025 were recycled, showing a shift toward circular manufacturing.
Amazon has also set a net-zero target for 2040 under its Climate Pledge. The company is one of the world’s largest corporate buyers of renewable energy and continues to invest heavily in clean power, logistics electrification, and low-carbon infrastructure.

Both companies argue that flexible accounting frameworks have supported these investments at scale.
The Bigger Challenge: Scope 3 and Digital Emissions
The debate over Scope 2 reporting is only part of a larger issue. For most large companies, Scope 3 emissions account for more than 70% of total emissions. These include supply chains, product use, and outsourced services.
In the technology sector, emissions are rising due to:
- Data centers,
- Cloud computing, and
- Artificial intelligence workloads.
Global data centers already consume about 415–460 terawatt-hours (TWh) of electricity per year, equal to roughly 1.5%–2% of global power demand. This figure is expected to increase sharply. The International Energy Agency estimates that data center electricity demand could double by 2030, driven largely by AI.
This creates a major reporting challenge. Even with cleaner electricity, total emissions can rise as digital demand grows.
Climate Reporting Rules Are Tightening Globally
The pushback comes as climate disclosure requirements are expanding and becoming more standardized across major economies. What was once voluntary ESG reporting is steadily shifting toward mandatory, audit-ready climate transparency.
In the European Union, the Corporate Sustainability Reporting Directive (CSRD) is now active. It requires large companies and, later, listed SMEs, to share detailed sustainability data. This data must match the European Sustainability Reporting Standards (ESRS). This includes granular reporting on emissions across Scope 1, 2, and increasingly Scope 3 value chains.
In the United States, the Securities and Exchange Commission (SEC) aims for mandatory climate-related disclosures for public companies. This includes governance, risk exposure, and emissions reporting. However, some parts of the rule face legal and political scrutiny.
The United Kingdom has included climate disclosure through TCFD requirements. Now, it is moving toward ISSB-based global standards to make comparisons easier. Similarly, Canada is progressing with ISSB-aligned mandatory reporting frameworks for large public issuers.
In Asia, momentum is also accelerating. Japan is introducing the Sustainability Standards Board of Japan (SSBJ) rules that match ISSB standards. Meanwhile, China is tightening ESG disclosure rules for listed companies through updates from its securities regulators. Singapore has also mandated climate reporting for listed companies, with phased Scope 3 expansion.
A clear trend is forming across jurisdictions: climate disclosure is aligning with ISSB global standards. There’s a growing focus on assurance, comparability, and transparency in value-chain emissions.
This regulatory tightening raises the bar significantly for corporations. The challenge is clear. Companies must:
- Align with multiple evolving disclosure regimes,
- Ensure emissions data is verifiable and auditable, and
- Expand reporting across complex global supply chains.
Balancing operational growth with compliance is becoming increasingly complex as climate regulation converges and intensifies worldwide.
A Turning Point for Global Carbon Accounting
The outcome of this debate could shape global carbon accounting standards for years.
If stricter rules are adopted, emissions reporting will become more precise. This could improve transparency and reduce greenwashing risks. However, it may also increase compliance costs and limit flexibility.
If the proposed changes remain optional, companies may continue using current accounting methods. This could support faster clean energy investment, but may leave gaps in reporting accuracy.
The new rules could take effect as early as next year, making this a near-term decision for global companies.
The push by Apple, Amazon, and other companies highlights a key tension in climate strategy. On one side is the need for accurate, real-time emissions reporting. On the other is the need for flexible systems that support large-scale clean energy investment.
As digital infrastructure expands and energy demand rises, how emissions are measured will matter as much as how they are reduced. The next phase of climate action will depend not just on targets—but on the systems used to track them.
