Duke University achieved carbon neutrality in 2024, marking a significant milestone in its sustainability journey. However, achieving this status does not mean the university eliminated all its emissions.
Instead, it represents a strategic balance between reducing emissions and offsetting those that remain. In Duke’s case, this included a $4 million investment in carbon offsets to neutralize its greenhouse gas (GHG) emissions.
Duke’s Path to Carbon Neutrality: Balancing Reductions and Offsets
Duke University, under the American College and University Presidents’ Climate Commitment, pledged to achieve carbon neutrality across its emissions-generating activities. Its Climate Action Plan (CAP) categorizes emissions into three scopes:
Duke’s approach aligns with GHG accounting standards from the World Resources Institute, ensuring comprehensive tracking and reduction strategies for all emission sources. The university has significantly cut GHG emissions through various levers including:
- Eliminating coal use,
- Boosting building and utility efficiency, and
- Reducing commuting emissions.
Future reductions are planned through off-site solar investments and campus upgrades like steam-to-hot-water conversions and heat recovery chillers. Duke remains on track to achieve its 2030 emissions goals.
However, 2023 emissions rose 9% compared to 2022, primarily due to air travel nearing pre-pandemic levels. Despite this, energy-related emissions are down 41% since 2007, and 2023 levels remain 21% lower than in 2019.

Duke’s progress toward carbon neutrality began in 2007 when it launched an institution-wide effort to measure and reduce emissions. By fiscal year 2022, Duke had reduced its emissions by 43%, with plans to reach a 45% reduction by its 2024 deadline.

- However, emissions rose slightly, requiring Duke to offset nearly 69% of its 2007-level emissions instead of the planned 55%.
This reliance on carbon offsets underscores a critical reality: achieving net-zero emissions without offsets is nearly impossible for large institutions. Matthew Arsenault, Duke’s assistant director of carbon and sustainability operations, highlighted that:
“No institution, no company is going to be carbon neutral without using carbon offsets. There’s literally no way to reduce your emissions actually to zero.”
Carbon offsets provide a mechanism to balance emissions from essential activities, such as powering campus buildings and transportation. These activities, while minimized through efficiency measures, can only be partially eradicated.
How Carbon Offset Credits Work
Carbon offsets allow institutions to balance emissions by funding projects that either reduce GHG emissions or remove existing emissions from the atmosphere. Institutions like Duke use these tools to purchase carbon accounting units traded on carbon markets. These markets enable organizations to buy and sell surplus credits to meet their sustainability and net zero goals.
For Duke, offsets became a practical and ethical way to achieve carbon neutrality, given the current limitations of emission reduction technologies.
Carbon Offsets in Action: The Key to Duke’s Carbon Neutrality
Duke’s approach to carbon offsets has evolved over the years. In 2009, the university launched the Duke Carbon Offsets Initiative (DCOI), the first university-based program of its kind. This initiative focused initially on developing new offset projects, such as a methane-capture effort at a North Carolina hog farm, where methane was converted into usable electricity instead of being released into the atmosphere.
Other early projects included residential energy efficiency upgrades, urban tree plantings, and solar installations. These efforts were designed to both reduce GHG emissions and align with Duke’s broader sustainability values.
As the 2024 carbon neutrality deadline approached, Duke University shifted its strategy to focus on larger, externally sourced projects to meet its offset needs.
Almost 80% of Duke’s carbon offset portfolio consisted of projects targeting ozone-depleting refrigerants, which contain potent GHGs that can leak into the atmosphere. These projects, developed in collaboration with international partners, represented a significant step in reducing emissions from refrigerants.
The remaining offsets focused on methane capture from dairy farms and landfills, similar to Duke’s earlier hog farm project. By investing in these projects, Duke ensured its offsets addressed emissions effectively and sustainably.
Ensuring Quality and Accountability
Duke’s commitment to sustainability extends beyond simply purchasing offsets. The university employs a rigorous verification process to ensure the quality and ethical standards of its investments. This process involves collaboration with Ruby Canyon Environmental, a registered verifier on carbon markets, to vet prospective offset projects.
To guide decision-making, Duke developed a comprehensive evaluation tool that includes detailed questions about each project. Criteria such as “additionality” (ensuring the emissions reductions would not occur without the project) and “permanence” (long-term commitment to emissions reductions) are prioritized.
Projects that meet these standards are further reviewed by an advisory committee of faculty and students before purchase. Fewer than 10% of potential projects pass Duke’s initial evaluation, highlighting the university’s commitment to investing in high-impact and high-integrity carbon offsets.
What’s Next? Duke’s Plan Beyond Neutrality
While offsets played a key role in Duke’s 2024 achievement, the university recognizes the importance of continuing to reduce its emissions. Efforts are ongoing to expand energy efficiency measures on campus and integrate more renewable energy sources into operations.
Duke University’s carbon footprint will significantly decrease by mid-2025 when three off-campus solar facilities come online. They have a combined capacity of 101 megawatts. These projects will provide about 50% of the campus’s electricity and contribute renewable energy to North Carolina’s grid for decades.
Additionally, Duke is exploring ways to include its health system and international campuses, such as Duke Kunshan University, in future emissions tracking.
The university is now determining its “next-generation” climate goals, focusing on sustaining its carbon-neutral status and further reducing its offset dependency. This includes exploring innovative carbon offset projects, expanding renewable energy use, and encouraging campus-wide engagement in sustainability initiatives.
Carbon offsets will remain an essential tool in the university’s strategy, but Duke aims to rely on them less as it continues to refine its emissions reduction efforts. With its comprehensive approach and commitment to quality, Duke serves as a model for other institutions seeking to balance sustainability goals with the practical realities of carbon offsetting.

Rio Tinto and Hydro Invest $45 Million to Cut Aluminum Emissions
Aluminum is everywhere, from cars to cans, but its production is a major carbon polluter. With global aluminum demand soaring, Rio Tinto and Hydro will $45 million in carbon capture tech to cut emissions. Could this be the breakthrough the industry needs?
The Carbon Footprint of Aluminum: A Heavyweight Problem
Aluminum production accounts for about 2% of global carbon emissions. The industry emits about 1.1 billion metric tons of CO₂ per year. That’s the same as the emissions from 150 million U.S. homes.
The electrolysis process alone is responsible for 791 million metric tons. Electrolysis is the main step in aluminum smelting. It uses carbon anodes, which release CO₂ during the process. This stage accounts for around 75% of a smelter’s direct CO₂ emissions.
With transportation, construction, and packaging relying on aluminum, we must reduce its environmental impact. Many aluminum producers are now seeking ways to cut emissions and reach net-zero targets.
A $45 Million Push for Carbon Capture
To tackle this, Rio Tinto and Hydro will invest $45 million over the next five years to develop carbon capture technologies for aluminum smelting. Smelting takes up most of the total GHG emissions of aluminum production.

The partnership focuses on finding, testing, and scaling up methods to capture and store CO₂ emissions from the electrolysis process. The initiative includes:
- Testing carbon capture technologies from laboratory research to real-world applications.
- Running pilot projects at Rio Tinto’s facilities in Europe and Hydro’s sites in Norway.
- Sharing research, costs, and expertise to accelerate progress.
Why Carbon Capture Is Difficult in Aluminum Smelting
Capturing carbon in aluminum production is more challenging than in other industries like power generation. This is because CO₂ levels in aluminum smelter emissions are extremely low (only about 1% by volume). This makes conventional carbon capture methods less effective.
There are two main approaches to capturing CO₂ from aluminum smelters:
- Point source carbon capture: This technology captures emissions at the source but must be adapted for lower CO₂ concentrations.
- Direct air capture (DAC): While typically used to remove CO₂ from the atmosphere, DAC could be modified to work in aluminum smelters.
Both methods need significant development to move from the lab to full-scale commercial use. This is where Rio Tinto and Hydro’s investment plays a key role in advancing these technologies.
Racing Toward Net-Zero: Can They Pull It Off?
This partnership is part of a broader push toward decarbonizing aluminum production. Both companies have already been working on independent initiatives, including:
- ELYSIS (Rio Tinto & Alcoa): A joint venture focused on developing carbon-free aluminum smelting technology.
- HalZero (Hydro): A new smelting process that eliminates CO₂ emissions from aluminum production.
While these long-term projects aim to create zero-emission aluminum, carbon capture can help reduce emissions from existing smelters. By combining their expertise, Rio Tinto and Hydro hope to make these technologies commercially viable sooner.
The Surge in Demand for Green Aluminum
As industries transition toward sustainable materials, demand for low-carbon aluminum is rising. Companies in automotive, construction, and packaging are seeking greener alternatives to meet climate targets.
Global aluminum demand is projected to rise nearly 40% by 2030, according to CRU International’s report for the International Aluminium Institute (IAI). The industry must produce an extra 33.3 million metric tons (Mt), increasing from 86.2 Mt in 2020 to 119.5 Mt in 2030. Key drivers of this growth include transportation, construction, packaging, and the electrical sector, which will account for 75% of total demand.

China will remain the largest consumer of semi-finished aluminum products by 2030. The Asian country makes up for over 45% of the market since 2015.
As industries push for lighter, more sustainable materials, aluminum’s role in global manufacturing will expand. This emphasizes the need for efficient production and decarbonization efforts to meet the rising demand sustainably.
Regulations are also pushing aluminum producers to reduce emissions. Governments worldwide are setting stricter carbon limits and introducing carbon pricing mechanisms that penalize high-emission industries. Carbon capture for aluminum production could give Rio Tinto and Hydro a competitive edge in this evolving market.
Beyond Carbon Capture: Other Ways to Cut Emissions
Beyond carbon capture, the aluminum industry is exploring other solutions to reduce emissions and energy use:
- Recycled Aluminum: Producing aluminum from recycled materials uses 95% less energy than primary production. Expanding aluminum recycling can significantly cut industry-wide emissions.
- Inert Anodes: Traditional carbon anodes release CO₂ during electrolysis, but inert anodes could eliminate these emissions. This technology is still in development but shows great potential.
- Renewable Energy-Powered Smelters: Switching from fossil fuels to solar, wind, or hydroelectric power can drastically reduce emissions from aluminum production.
By combining these strategies with carbon capture, the industry can move closer to achieving net-zero emissions.
Rio Tinto and Hydro’s partnership marks a major step toward decarbonizing aluminum smelting. If successful, their investment could lead to groundbreaking advancements that benefit the entire sector. By working together, they are taking a critical step toward making low-carbon aluminum a reality—a move that aligns with global climate goals and industry sustainability efforts.

Clean Energy Investment Hits $2.1 Trillion: A Step Closer to Net Zero or a Missed Mark?
Global investment in energy transition technologies reached an all-time high of $2.1 trillion in 2024, according to BloombergNEF. This marked an 11% increase from the previous year, driven by EVs, renewable energy, and advanced grid infrastructure. While the record-breaking investment highlights growing momentum toward cleaner energy solutions, experts caution that current funding levels fall far short of what’s needed to meet global climate targets.
Countries are ramping up investments in low-carbon energy to tackle climate change and meet Paris Agreement targets. However, experts warn that the current spending pace isn’t enough.
Bloomberg’s latest Energy Transition Investment Trends report shows that to hit net-zero emissions by 2050, global investment needs to triple to $5.6 trillion annually between 2025 and 2030. The gap is massive, highlighting the urgent need for bigger commitments and faster action.
Why do Energy Transition Investments Matter for Net Zero?
The energy sector plays a crucial role in addressing climate change as it contributes to approximately 75% of global greenhouse gas emissions. With temperatures rising every year, this transition to clean energy has become increasingly urgent.
Countries have committed to reducing emissions sustainably, aiming to keep global temperature rise below 2°C and limiting it to 1.5°C. The Paris Agreement target would be fulfilled only when the energy sector can reach net zero emissions by 2050.
This transition significantly requires phasing out fossil fuels fairly and systematically while eliminating inefficient fossil fuel subsidies that hinder transition.
Closing the Funding Gap
Now talking about the key factor i.e. investments. Governments and businesses are focusing on sustainable solutions like electric vehicles (EVs) and renewable energy. This certainly gives a positive signal towards developing a low-carbon economy.
However, there’s a funding gap. As said before, global investments in energy transition technologies reached $2.1 trillion. Yet, this amount is only 37% of the annual $5.6 trillion required from 2025 to 2030 to meet net-zero targets.
Achieving the net zero target will require not only increased funding but also bold policies and stronger international cooperation. Governments will need to be more decisive in scaling up efforts, remove barriers, and foster innovation across energy sectors.
For instance, accelerating progress in renewable energy, electrified transport, and grid modernization. With faster progress the funding gap can close and combating climate change will be easier.
Which Sector Took the Lead?
The report revealed that last year electrified transport topped the charts, pulling in $757 billion in funding. This includes investment in electric cars, commercial EV fleets, public charging networks, and fuel cell vehicles. With the EV market booming, it’s clear the world is betting big on cleaner mobility solutions.
Renewable energy also performed well. Globally $728 billion was invested in wind, solar, biofuels, and other green power sources. Additionally, power grid modernization secured $390 billion for upgrades like smarter grids, improved transmission lines, and digital tools to manage energy demand. Nuclear investment was flat at $34.2 billion.
In contrast, investment in emerging technologies, like electrified heat, hydrogen, carbon capture and storage (CCS), nuclear, clean industry and clean shipping, reached only $155 billion, for an overall drop of 23% year-on-year.
Investment in these sectors was hampered by affordability, technology maturity, and commercial scalability. Thus, the public and private sectors must work together to progress these technologies to reduce emissions.
Mature vs. Emerging: Where Clean Energy Investments Stand
Bloomberg further categorized investments into “mature” and “emerging” sectors. Mature technologies like renewables, energy storage, EVs, and power grids dominated funding while emerging sectors such as hydrogen, CCS, electrified heating, clean shipping, nuclear, and sustainable industries lagged.
- The mature Sector attracted $1.93 trillion in investments, accounting for the bulk of global energy transition funding.
- The emerging sector closed $154 billion in investments, making up just 7% of the total.
Despite facing challenges like higher interest rates and changing policies, mature technologies saw steady growth, increasing by 14.7% compared to the previous year. Their proven scalability and established business models make them trustworthy for governments and investors.
In contrast, emerging technologies faced significant setbacks. Investment in these sectors dropped by 23%, mainly due to high costs, unproven scalability, and limited commercial readiness. These challenges continue to slow their progress and hinder their potential to scale effectively

China Leads the Energy Investment Race
In 2024, mainland China emerged as the top market for energy transition investment, contributing $818 billion—a 20% rise from the previous year. This growth accounted for two-thirds of the global increase, with sectors like renewables, energy storage, nuclear, EVs, and power grids seeing robust development. China’s total investment surpassed the combined contributions of the US, EU, and UK.
Notably, China’s energy investment now equals 4.5% of its GDP, outpacing other nations like the EU and the US. While the US remains the second-largest market with $338 billion, Germany took third place, investing $109 billion in clean energy.
Other players like India and Canada also contributed to the global growth story, increasing investments by 13% and 19%, respectively.
2035 Forecast: A 3.6X Surge in Clean Energy Spending
To conclude Bloomberg came up with an investment forecast for 2030. The report says clean energy spending is set to rise sharply after 2030.
- Between 2031 and 2035, annual investments are projected to reach $7.6 trillion—3.6 times higher than 2024 levels.
- This marks a 37% increase compared to the annual spending expected between 2025 and 2030.
Electrified transport, including EVs and charging infrastructure, will continue to dominate investments during this period. As demand for clean mobility grows, funding for these technologies is likely to accelerate further, supporting the transition to a low-carbon future.
Thus, this steep rise in renewable energy spending after 2030 highlights the necessity for quick action. However, this year with Trump taking over, his stance on clean energy investment has been mixed. He has continued to promote traditional energy sources over clean energy, aligning with his “America First” agenda.
