Projected Decline in Weight Loss Drug Prices by 2026: What You Need to Know

Massive demand for weight loss medications

Surge in demand for drugs like Wegovy, Victoza, and Ozempic leads to shortages

The blockbuster weight loss drug semaglutide, along with competitors, offers potential solutions to the global obesity crisis. However, access remains limited for many who could greatly benefit from these innovations, though changes are on the horizon.

Historically, weight loss drugs have been scarce; yet, by the end of 2024, manufacturers are expected to meet the skyrocketing demand. Nevertheless, treatments like semaglutide (marketed as Wegovy or Ozempic) continue to carry hefty price tags, often reaching thousands of dollars annually.

This pricing structures keeps these essential medications out of reach for the over 1 billion individuals affected by obesity globally. In the U.S., a mere 3 percent of the population utilizes weight-loss medications, with the numbers dipping below 1 percent in other countries, according to Morgan Stanley.

Looking ahead, 2026 promises significant developments, including the approval of orforglipron in multiple countries. This new medication mimics the GLP-1 hormone, known for its appetite-reducing properties. Unlike semaglutide, orforglipron, as a small molecule, offers tablet-based administration.

“Tablets are inexpensive to produce, simple to store, and easy to distribute,” explains Dr. Laura Heisler from the University of Aberdeen, UK. “In essence, the medication can reach a broader audience in need.”

In contrast, semaglutide is a larger molecule and a type of protein. Polymer drugs like these are generally challenging and costly to produce. They often require injections, complicating their supply and driving up costs. This has been a significant barrier to fulfilling the demand for GLP-1 drugs.

It’s important to note that there is a semaglutide version in pill form, Rybelsus, approved for type 2 diabetes. Novo Nordisk, the manufacturer, has also sought approval for a weight loss variant.

However, Rybelsus isn’t just any medication; it includes semaglutide alongside sulcaprosate sodium, which neutralizes stomach acid to facilitate absorption into the bloodstream. To maximize effectiveness, it must be taken at least 8 hours post-meal, with no food or drink for 30 minutes.

This complexity is part of the reason orforglipron has a lower production cost compared to semaglutide—it can be taken without the stringent requirements of medications like Rybelsus.

Furthermore, the introduction of orforglipron will foster competition among pharmaceutical companies. While Lilly, the producer of Orforglipron, has yet to disclose pricing, it has been shown to be less costly than other GLP-1 alternatives.

The sole drawback is that orforglipron appears less effective; those on the highest doses typically lose about 10% of body weight over 72 weeks, compared to 14% with semaglutide. Further research is needed to validate these findings.

Another critical development is the anticipated expiration of semaglutide patents in nations such as China, India, Brazil, Canada, and Turkey—home to a significant population. This could pave the way for generic versions to enter the market.

Although generics must meet the same standards as their branded counterparts, they often come at a fraction of the cost. “Once a drug loses patent protection, generic competition usually leads to price reductions of up to 90%,” states Jeremy Durant of Medicines UK, the association for generic drug manufacturers.

This shift may expand access to these crucial treatments. That said, the World Health Organization (WHO) recently advised that patients should also receive counseling about behavioral modifications and lifestyle changes to maximize the efficacy of medications. “Drugs alone won’t address the global obesity crisis,” says Francesca Ceretti of WHO.

U.S. mRNA Cancer Vaccines: Projected Costs Exceed $75 Billion

Vaccine Development

Significant Economic Benefits of mRNA Cancer Vaccines Currently Under Development

In August 2025, the United States announced a $500 million cut in funding for vaccine development, jeopardizing the potential advantages of mRNA cancer vaccine research. According to Alison Galvani from Yale University and colleagues, this reduction poses significant risks to future developments.

The team’s analysis indicates that the treatment advancements observed in current clinical trials could prevent nearly 50,000 deaths, translating to an economic value of $75 billion. “This estimate is based on just one annual cohort of patients for each cancer type,” stated the researchers.

Experts caution that diminishing federal investment in mRNA vaccine technology risks undermining these crucial benefits.

Recent research highlights that many of the most effective cancer treatments leverage the body’s immune response to combat tumors. mRNA vaccines can specifically activate the immune system to identify proteins unique to cancer cells, offering a tailored approach to cancer treatment.

To evaluate the potential impact of these vaccines, Galvani and her team analyzed 32 ongoing mRNA cancer vaccine clinical trials in the U.S. They identified the top 11 promising trials and estimated the additional years of life these treatments could provide if widely administered to eligible patients within a year.

Furthermore, the researchers calculated the annual value of an additional year of life, utilizing statistical measures regarding how much individuals would pay for such benefits. They applied values established by the U.S. Department of Health and Human Services to assess the implications of potential regulatory shifts.

Although the annual estimates may be optimistic—given that some vaccine candidates may not gain approval—Oliver Watson from Imperial College London employed a similar framework, estimating that COVID-19 vaccines have yielded global health and economic benefits ranging from $5 trillion to $38 trillion.

If researchers evaluated the cumulative value of multiple cohorts receiving cancer treatments and extended their analysis over a longer time frame, the potential benefits would be substantially greater. “These estimates are undoubtedly conservative,” Watson notes.

2025 Projected to be the Second Hottest Year on Record

This year is poised to be the second hottest on record, following 2024, with numerous areas facing extraordinary storms, wildfires, and heat waves.

The European Union’s Copernicus Climate Change Agency (C3S) reports that the average temperature in 2025 is currently 1.48 degrees Celsius above the pre-industrial baseline. If this holds, it will tie with 2023, falling only behind 2024, which recorded a rise of 1.6 degrees Celsius compared to pre-industrial levels.

While the planet warmed during the El Niño phase in 2024, it is now experiencing a La Niña phase, where the upwelling of cold water in the tropical Pacific Ocean typically results in lower global temperatures. However, fossil fuel emissions are projected to set a new record in 2025, leading to rising temperatures and exacerbating catastrophic weather events.

“The truth is that extreme events impact communities, societies, and ecosystems. We understand that in a warmer world, these extreme events will be more frequent and intense,” explains Samantha Burgess from C3S. “The storms will intensify due to increased moisture in the atmosphere.”

This summer, a heatwave in Europe resulted in an additional 16,500 fatalities associated with climate change. In October, Hurricane Melissa, the strongest hurricane to strike Jamaica, claimed over 80 lives and caused significant damage, with financial losses reaching $8.8 billion. Research from World Weather Attribution indicates that climate change enhanced Melissa’s rainfall by 16% and reduced wind speed by 7%.

In November, a series of cyclones and storms triggered landslides and flooding in Sri Lanka, Indonesia, Thailand, Malaysia, and Vietnam, resulting in over 1,600 deaths.

Currently, Arctic sea ice extent is at its lowest recorded level for this time of year, and Antarctic sea ice is also below normal levels.

According to C3S, the three-year moving average temperature is projected to surpass 1.5 degrees Celsius for the first time since the pre-industrial era. Scientists anticipate that global warming will exceed the long-term average of 1.5°C by 2029, falling short of the Paris Agreement objectives.

“There isn’t a clear boundary at 1.5 degrees, but we know that impacts worsen beyond that threshold,” Burgess states. “We are also nearing a critical tipping point.”

According to an October report, a tipping point has seemingly been reached, leading to the irreversible decline of tropical coral reefs, and the world could soon face additional tipping points, including the demise of the Amazon rainforest and the collapse of the Greenland and West Antarctic ice sheets, along with the decline of Antarctic sea ice.

Google’s Emissions Projected to Increase 51% Due to Rising AI Electricity Demands

Since 2019, Google’s carbon emissions have surged by 51%, with artificial intelligence proving to be a hindrance to tech firms’ sustainability initiatives.

While companies are pouring resources into renewable energy and carbon capture technologies, they struggle to manage emissions in Range 3, which originates further down the supply chain and is significantly influenced by the expanding data center capabilities required for artificial intelligence.


The company noted a 27% year-on-year increase as it grapples with decarbonization amidst rising energy demands.

Data centers are crucial for training and operating AI models like Google’s Gemini and OpenAI’s GPT-4. The International Energy Agency projects that the total electricity consumption of data centers could reach double the level from 2022, with Japan’s electricity demand expected to hit 1,000 TWh (terawatt hours) by 2026. AI accounts for 4.5% of global energy production, according to estimates from Semianalysis for the year 2030.


The report expresses concerns that the rapid advancement of AI may trigger “nonlinear growth in energy demand,” complicating predictions for future energy requirements and emissions trajectories.

Additionally, Google pointed out the slow progress in new low-carbon power generation technologies. Small Modular Reactors (SMRs), which are compact nuclear power plants designed for quick deployment to support the grid, are seen as a promising solution to lower the carbon footprint of data centers. Areas hosting numerous data centers could benefit from one or more SMRs to significantly cut down their electricity-related carbon emissions.

According to the report, the development of these technologies is lagging behind schedule. “The main obstacle is the slow rollout of large-scale carbon-free energy technologies, making it highly challenging to reach goals by 2030.

It further indicated that Scope 3 emissions pose a “challenge,” with Google’s total ambitions representing 11.5 million tons of CO2 equivalent, marking an 11% year-on-year rise since 2019, equating to a 51% increase. This is primarily driven by heightened emissions from the supply chain, with Scope 3 emissions surging by 22% in 2024.

Google has made significant strides in acquiring clean energy, signing over 170 contracts for more than 22 gigawatts since 2010. In 2024, 25 of these contracts added 2.5GW of fresh clean energy to its operations, marking a record year in clean energy transactions with an agreement totaling 8GW.


The company has also achieved one of its environmental goals ahead of schedule by eliminating plastic packaging. Google announced that all new products launched and produced in 2024 will be entirely plastic-free. This goal was initially set for the end of 2025.

The report adds that AI may offer a “net positive potential” for the climate, with aspirations that emissions reductions facilitated by AI applications will outweigh the emissions generated by AI itself, including the energy used by data centers.

Google envisions aiding individuals, cities, and other partners in collectively lowering carbon equivalent emissions by 2030 through AI-powered products. These innovations can enhance energy usage predictions, reduce waste, and optimize solar panel placement to maximize energy generation.

AI Projected to Clarify Nearly 50% of Data Center Electricity Consumption by Year-End: A Green Economy Perspective

Artificial intelligence systems may represent nearly 50% of a data center’s power consumption by the end of this year, according to a recent analysis.

These estimates, provided by Digiconomist Tech Sustainability founder Alex de Vries-Gao, echo a prediction from the International Energy Agency regarding AI’s energy needs by the decade’s end, similar to current usage in Japan.

De Vries-Gao’s calculations, as detailed in the Sustainable Energy Journal Joule, are based on the energy consumed by chips developed by companies like Nvidia and Advanced Micro Devices that are used for training and operating AI models. The study also factors in energy usage of chips from other providers, such as Broadcom.

The IEA reported that all data centers (excluding those for cryptocurrency mining) consumed 415 terawatt hours (TWh) of electricity last year. De Vries-Gao asserts that AI currently contributes to 20% of that total.

He highlights various factors influencing his calculations, including energy efficiency in data centers and the power requirements of cooling systems that manage AI workloads. Data centers serve as the central nervous system for AI technology, making their energy consumption a significant sustainability issue for AI development and usage.

De Vries-Gao projects that by the end of 2025, AI systems could consume up to 49% of total data center energy, potentially reaching 23 gigawatts (GW) — double the total energy usage of the Netherlands.

However, De Vries-Gao mentioned that several factors might dampen hardware demand, including reduced interest in applications like ChatGPT. Geopolitical tensions creating restrictions on AI hardware production, such as export limitations, are another hurdle. De Vries-Gao notes the challenges faced by Chinese access to chips, which led to the introduction of the Deepseek R1 AI model that purportedly required fewer chips.

“These innovations could help decrease both AI processing and energy costs,” said De Vries.

That said, he mentioned that enhanced efficiency could further encourage AI adoption. Additionally, a trend referred to as “sovereign AI,” where countries aim to create their own AI systems, might spur hardware demand. De Vries-Gao cited US Data Centre startup Crusoe Energy, which secured 4.5GW of gas-powered energy capacity, making it a leading contender for potential clients like OpenAI through its Stargate venture.

“These early indicators suggest that [Stargate] data centers may increase our reliance on fossil fuels,” noted De Vries-Gao.

On Thursday, OpenAI unveiled its Stargate project in the United Arab Emirates, marking its expansion outside the United States.

Last year, Microsoft and Google acknowledged that AI poses risks to meet their internal environmental objectives.

De Vries-Gao commented that information about AI’s power requirements is increasingly scarce, describing the industry as “opaque.” While the EU AI Act mandates that AI firms disclose energy consumption related to model training, it does not cover daily usage metrics.

Professor Adam Sobey, mission director for sustainability at the UK’s Alan Turing Institute, stressed the importance of enhanced transparency regarding the energy usage of AI systems and the potential savings from advancing carbon reduction sectors like transport and energy.

Sobey remarked, “We don’t necessarily need an extensive number of compelling use cases for AI to offset the energy costs incurred upfront.”

Global temperatures are projected to rise by 1.9-3.7°C by the year 2100

Coal power plants contribute to global warming

Walaiporn Sangkeaw

Current policies of governments around the world are likely to result in global warming of between 1.9 and 3.7°C by 2100, with potentially more to come in the 22nd century.

“Each year, 2,100 people continue to emit more CO2 as global temperatures rise,” said Zeke Hausfather, a climate scientist at Stripe, a California-based software company that invests in carbon removal technologies. states.

His conclusions are based on a review of more than a dozen studies published over the past five years, looking at the implications of current policies over the past five years. According to these studies, the world is most likely to warm between 2.3 and 3°C by 2100.

However, these numbers do not fully take into account the uncertainties about future emissions of greenhouse gases as a result of human actions and how the climate system will respond to those emissions. Including these uncertainties gives a wider range of 1.9–3.7 °C.

These numbers reflect the most likely range of scenarios from the 5th to 95th percentile. This means that even with current policies, there is a small chance of a maximum warming of 4.4°C this century.

The good news is that all recent studies agree that very high emissions scenarios are currently unlikely. For these, warming of 4°C or more before 2100 is the most likely outcome.

That's because the worst-case scenarios considered by climate scientists were never all that plausible to begin with, Hausfather says, but it also reflects real progress in limiting emissions growth. and coal is currently expensive.

If climate policies strengthen and technological advances continue to exceed expectations, future emissions could be even lower than assumed in these studies, but this is not guaranteed and The rise of energy-hungry technologies like intelligence could do the opposite.

“It's definitely possible to imagine a world where AI accelerates rapidly and near-term emissions increase beyond what we think will happen today,” Hausfather says.

But he doesn’t think AI-related emissions will make much of a difference in the long term. “It’s certainly not in line with rapid emissions reductions, but it’s hard to see that in itself putting us on track for a significantly different end-of-the-century outcome,” Hausfather says. .

Global cancer-related deaths projected to nearly double by 2050

Breast cancer cells metastasized to the liver

Global cancer deaths are expected to nearly double by 2050, primarily in low- and middle-income countries.

Habtum Bisaifu The professor and his team from Australia’s University of Queensland made the discovery by looking at recent morbidity and mortality figures for 36 types of cancer in 185 countries from the World Cancer Observatory’s database. These rates were then applied to the United Nations Development Programme’s 2050 population projections to predict future cases and deaths.

Researchers predict that the total number of cancer cases worldwide is expected to increase by nearly 77% between 2022 and 2050, representing 20 million cases in 2022 and an additional 15.3 million cases in 2050. It means that the number of people will increase. The number of deaths from cancer worldwide also increased by almost 90% during this period, with 9.7 million people dying from the disease in 2022, and 8.8 million people expected to die from the disease in 2050. It will be.

The biggest increases are expected to occur in countries that rank low or middle on the United Nations’ Human Development Index, which is based on life expectancy, education levels, and per capita income. In countries with low scores, such as Niger and Afghanistan, cancer incidence and deaths are expected to nearly triple on average by 2050. Meanwhile, countries with very high scores, such as Norway, are projected to see an average increase in infections and deaths of more than 42% and 56%, respectively.

This corroborates other evidence that: The number of cancer cases is on the risesay Andrew Chan at Massachusetts General Hospital in Boston, and he was not involved in the study. Multiple factors are likely driving this, he says, including people living longer and increasing their risk of cancer. However, this study did not take into account the emergence of new or more effective treatments.

Chan says the least developed countries will probably experience the largest increase due to “the so-called Westernization of the population.” “Some of the habits traditionally considered to be associated with higher cancer risk, such as rising obesity rates and poor diet, are becoming trends in low- and middle-income countries.”
