Eco-driving measures could significantly reduce vehicle emissions
Any motorist who has ever waited through multiple cycles for a traffic light to turn green knows how annoying signalized intersections can be. But sitting at intersections isn't just a drag on drivers' patience—unproductive vehicle idling could contribute as much as 15% of the carbon dioxide emissions from U.S. land transportation.

In 2023, I wrote an article about two Bioenergy-with-CCS 🌲🔥🍃 (BECCS) projects in Denmark🇩🇰, which is somewhat timely given recent news.
It was published on the shipping news page Fathom World, which is no longer online, so I have republished it.
Back then, Ørsted announced plans for carbon capture and storage at two of its bioenergy power plants (Asnæsværket and AvedŸreværket). 🧵

Ørsted plans to ship carbon emissions from two of its biomass-fired power plants in Denmark to the Northern Lights project in Norway.

Global CO2 storage capacity may be drastically overstated, study finds
A new analysis suggests that the “prudent” storage available for carbon dioxide to head off further global warming is more limited than other recent estimates. Accounting for the risks associated with carbon capture and storage (CCS), the study found that stashing carbon underground in suitable locations would likely reduce warming by only about 0.7° Celsius […]

Carbon-Negative Commuting: Integrating Urban Design, Behavior, and Technology for Climate-Positive Mobility
Commuting contributes substantially to urban greenhouse gas emissions and represents a critical focus for climate mitigation efforts. This paper explores the multifaceted nature of commuting-related carbon dioxide emissions by analyzing the influence of urban form, socio-economic attributes, and individual behaviors. It reviews analytical approaches including structural equation modeling, multi-objective optimization, and agent-based simulations that have been employed to understand and mitigat…

Amazon Rainforest hits record carbon emissions from 2024 forest fires
In 2024, the Amazon Rainforest underwent its most devastating forest fire season in more than two decades. According to a new study by the European Commission’s Joint Research Centre, the fire-driven forest degradation released an estimated 791 million metric tons of carbon dioxide in 2024, a sevenfold increase compared with the previous two years. The […]

Satellite data reveal African grasslands' carbon uptake rises with rainfall, unlike forests and savannas
Africa is a source of uncertainty in carbon cycle calculations. By some estimates, the continent's landscapes emit 2.1 billion tons more carbon dioxide than they take up each year—about equal to 1.5 times the annual emissions from coal-fired power plants. But other estimates are almost the complete opposite, suggesting that the continent's copious plant matter takes up 2.0 billion more tons of carbon dioxide per year than it releases.

CarboNet: A Finite-Time Combustion-Tolerant Compartmental Network for Tropospheric Carbon Control
While governments and international organizations have set the net-zero target to prevent a climate event horizon, practical solutions are lacking mainly because of the impracticability to completely replace combustion processes. Hence, in this paper, we first design a compartmental network whose states must remain in the nonnegative orthant for physical consistency and in which the carbon dioxide emissions result from the combustion of diesel in vehicles and gas in house heaters. Then, we desi…

High-pressure electrolysis sustainably converts captured CO₂ into industrial-grade ethylene
Researchers at King Abdullah University of Science and Technology have unveiled a breakthrough system that could change the way we think about carbon emissions. Published in Nature Catalysis the researchers outline a system for converting captured carbon dioxide (CO₂) into industrial-grade ethylene, a commodity chemical essential to plastics, textiles, and construction. The work shows a direct path to transforming greenhouse gas emissions into valuable chemical products.

Climate-protecting carbon sinks of EU forests are declining
Forests cover about 40% of the EU's land area. Between 1990 and 2022, they absorbed around 10% of the continent's man-made carbon emissions. However, the carbon dioxide absorption capacity of forests, also known as carbon sinks, is becoming increasingly weaker.

Decade-long Emission Forecasting with an Ensemble Model in Taiwan
Taiwan's high population and heavy dependence on fossil fuels have led to severe air pollution, with the most prevalent greenhouse gas being carbon dioxide (CO2). There-fore, this study presents a reproducible and comprehensive case study comparing 21 of the most commonly employed time series models in forecasting emissions, analyzing both univariate and multivariate approaches. Among these, Feedforward Neural Network (FFNN), Support Vector Machine (SVM), and Random Forest Regressor (RFR) achie…

Carbon credits have little to no effect on making companies greener, study reveals
Many companies across the world use carbon credits as part of their climate strategies to offset emissions. A carbon credit is a certificate that represents the reduction, avoidance or removal of one ton of carbon dioxide from the atmosphere. While organizations claim these credits help them reduce their environmental impact, there is debate about whether companies that buy credits decarbonize faster. However, an in-depth study of 89 multinationals, published in Nature Communications, reveals t…

Taking the Highway or the Green Road? Conditional Temperature Forecasts Under Alternative SSP Scenarios
In this paper, using the Bayesian VAR framework suggested by Chan et al. (2025), we produce conditional temperature forecasts up until 2050, by exploiting both equality and inequality constraints on climate drivers like carbon dioxide or methane emissions. Engaging in a counterfactual scenario analysis by imposing a Shared Socioeconomic Pathways (SSPs) scenario of "business as-usual", with no mitigation and high emissions, we observe that conditional and unconditional forecasts would follow a s…

SERS Raman detection of the CO$_2$ Moisture Swing
The development of scalable, energy-efficient carbon dioxide capture technologies is critical for achieving net-zero emissions. Moisture swing sorbents offer a promising alternative to traditional thermal regeneration methods by enabling reversible CO$_2$ binding through humidity-driven ion hydrolysis. In this study, we investigate the anion speciation dynamics in two classes of MS materials, an anion-exchange resin with bicarbonate anion and activated carbon impregnated with potassium bicarbon…

Toward better understanding of energy in economics: Improvements to the Garrett thermodynamic economic model yield a robust system
In a series of papers, Garrett, et al, presents a thermodynamic economic model first laid out in "Are there basic physical constraints on future anthropogenic emissions of carbon dioxide?". This model contains a key conceptual issue that obscures a robust system. This system can link to the Energy Based Cobb-Douglas equation. The key conceptual problem is the belief that $λ$, the symbol for growth in Garrett 2011 would disprove the model if it was not constant. However, $λ$ cannot be a cons…

Increasing solar power generation in the U.S. by 15% could lead to an annual reduction of 8.54 million metric tons of carbon dioxide (CO2) emissions, according to a new study led by Harvard T.H. Chan School of Public Health. The researchers found that the climate benefits of solar power differ markedly across U.S. regions, pinpointing where clean energy investments return the greatest climate dividends.
