Most industrial greenhouse gas (GHG) emissions come from energy use. By improving energy efficiency, the world can cut energy consumption, lower emissions, and save on costs. It’s a smart and cost-effective first step toward decarbonization and businesses are continuing to pour funds into energy efficiency initiatives and technologies worldwide as the International Energy Agency (IEA) reported.
The IEA’s Energy Efficiency 2024 highlights key trends in energy intensity, demand, prices, and policies. It also offers insights into system-wide themes including investment, which this article will delve into in detail.
Driving Change: What Leads the Energy Revolution?
The report shows that energy efficiency investments could remain resilient in 2024, with total spending projected to reach around $660 billion. This level matches the record set in 2022 and highlights the steady commitment to sustainable energy use. These investments span sectors like transport, buildings, and industry, driven by the need to reduce emissions and enhance energy efficiency amid fluctuating economic conditions.

Since 2019, global energy efficiency investments have surged by 45%, fueled by the energy crisis and significant government spending post-Covid-19. The transport sector has seen the highest growth, with a 77% rise, followed by buildings at 34% and industry at 13%.

However, from 2022 to 2024, the trend shifted. Investments in buildings dropped by 7%, while transport saw a 14% rise, and industry remained steady.
A key driver for the trend is the push for efficient electrification, especially in the electric vehicle (EV) sector across China, Europe, and North America. EV sales, particularly in emerging markets, have supported this trend.
However, as energy prices stabilize and government stimulus wanes, overall global investment has plateaued. Rising inflation and interest rates also pose challenges for financing efficiency upgrades.
Emerging Markets Take the Spotlight in Efficiency Investments
The growth of efficiency-related investments in 2024 is uneven across regions. Emerging markets and developing economies (EMDEs) are expected to lead.
Africa is projected to see a 60% rise, the Middle East 40%, and Central and South America over 20%. China will also witness nearly 10% growth.

Conversely, advanced economies are stabilizing after years of crisis-driven spending. Europe is set for a slight decline, while North America will see a modest 5% increase.
Despite slower growth in these regions, they still account for the bulk of global energy efficiency investments—95% of total spending occurs in Europe, Asia Pacific, and North America, regions responsible for about 75% of global energy demand.
Transport Electrification: A Surge in EV Sales
Globally, the electrification of transport has gained momentum. By 2024, around one in five new cars sold will be electric.
EV sales reached 14 million in 2023, making up 18% of total car sales, and this figure is expected to grow to 17 million in 2024. The bulk of these sales occurred in China, Europe, and North America, which accounted for 95% of global EV sales.
In EMDEs, the focus remains on two- and three-wheelers. These vehicles dominate markets in regions like Southeast Asia and Latin America. China leads in two-wheeler sales, though global sales in this category dropped 18% in 2023 due to supply chain disruptions.
India, however, saw a 40% increase in electric two-wheeler sales and continued growth in three-wheelers, spurred by government initiatives like the Electric Mobility Promotion Scheme.
- RELATED: Is the EV Market’s Momentum Slowing?

According to S&P Global data represented by the chart below, global passenger plug-in EV sales could reach over 33 million units by 2028. That’s almost a 104% increase in EV units sold. China is set to take the biggest growth in sales.
The number of people projected to use EVs for the same period (penetration rate) will also double by 2028 compared to 2024.

Building Smarter: A Post-Crisis Slowdown
Investment in energy-efficient buildings boomed during the energy crisis, driven by technologies like heat pumps. In 2022, heat pump sales peaked, particularly in Europe, where they are central to long-term climate goals.

However, this momentum slowed in 2023 due to high electricity prices and reduced government support. For instance, Italy’s Superbonus program, which heavily subsidized energy-saving renovations, was phased out in 2024. This program alone accounted for more than half of Italy’s building sector investments in 2023.
Meanwhile, heat pump deployment in China has seen modest growth. These trends highlight the critical role of government policies in sustaining investment in building efficiency.
ESCOs and the Power Players Behind the Efficiency Boom
The energy service company (ESCO) market experienced a slight decline in 2023, dropping by 2.2%. Despite this, the market size remains robust at over $35 billion, supported by strong policies in regions like the U.S.
Federal programs, such as the Federal Energy Management Program, have bolstered ESCO activities, which grew by 54% between 2021 and 2023 in the U.S.

China leads the global ESCO market, with investments exceeding $20 billion in 2023, accounting for half the global total. The majority of ESCO investments target the buildings sector, followed by industrial applications and energy storage.
Among the major players in the ESCO market, some of the interesting companies making waves in the sector include:
- Johnson Controls is a global leader in smart building solutions, offering advanced technologies and services to enhance building performance and sustainability. In energy efficiency, Johnson Controls has made significant progress by implementing high-capacity heat pumps and optimizing energy use in various industries. They have contributed to over $6 billion in customer projects worldwide, driving sustainability and reducing carbon footprints.

It helps clients achieve sustainability goals through advanced technologies like microgrids, battery storage, and renewable energy systems.
Scaling Up: What’s Needed for 2030?
To meet net-zero targets, energy efficiency investments must triple by 2030, reaching $1.9 trillion annually, per the report. The IEA’s NZE Scenario underscores the importance of a comprehensive strategy tailored to each country’s needs.
In emerging economies, efforts focus on improving building performance and electrifying transport. In sub-Saharan Africa, the transition to clean cooking fuels is a top priority. Advanced economies, meanwhile, focus on retrofitting older infrastructure, deploying heat pumps, and scaling up EV infrastructure.
Ultimately, energy efficiency investment is vital for meeting global climate goals and expanding investment to underrepresented regions will be key to accelerating progress.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

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.
