Methane leaks from dormant oil and gas wells in Canada are seven times worse than thought, study suggests
Methane emissions from Canada's non-producing oil and gas wells appear to be seven times higher than government estimates, according to a new study led by researchers at McGill University. The findings spotlight a major gap in the country's official greenhouse gas inventory and raise urgent questions about how methane leaks are monitored, reported and managed.

Millions of non-producing oil and gas wells around the world are leaking methane and other contaminants,
contributing to increased greenhouse gas emissions and polluting our water, soil, and air.
The total annual methane emissions from non-producing wells in Canada is 7 times higher than estimated in Canada’s National Inventory Report
The U.S. no longer even estimates it's methane emissions

After stabilizing around 2000-2005, atmospheric concentrations of greenhouse gas methane started to rise again, accelerating until a few years ago.
At least the increase seems to be slowing down since 2021.

Investigating State-of-the-Art Planning Strategies for Electric Vehicle Charging Infrastructures in Coupled Transport and Power Networks: A Comprehensive Review
Electric vehicles (EVs) have emerged as a pivotal solution to reduce greenhouse gas emissions paving a pathway to net zero. As the adoption of EVs continues to grow, countries are proactively formulating systematic plans for nationwide electric vehicle charging infrastructure (EVCI) to keep pace with the accelerating shift towards EVs. This comprehensive review aims to thoroughly examine current global practices in EVCI planning and explore state-of-the-art methodologies for designing EVCI plan…

Evaluation methodology of Model Predictive Controllers for building's energy systems
Climate change poses a serious threat to the Earth's ecosystems, fueled primarily by escalating greenhouse gas emissions. Among the main contributors, the building sector stands out due to its significant energy demand. Addressing this challenge requires innovative techniques in the control of energy systems in buildings. This paper deals with the formulation of a methodology designed to evaluate the performance of these controllers. The evaluation process involves the establishment of a compre…

Predict, Reposition, and Allocate: A Greedy and Flow-Based Architecture for Sustainable Urban Food Delivery
The rapid proliferation of food delivery platforms has reshaped urban mobility but has also contributed significantly to environmental degradation through increased greenhouse gas emissions. Existing optimization mechanisms produce sub-optimal outcomes as they do not consider environmental sustainability their optimization objective. This study proposes a novel eco-friendly food delivery optimization framework that integrates demand prediction, delivery person routing, and order allocation to m…

Decarbonizing Mongolia's Energy Sector: A Techno-Economic Analysis of Hybrid Energy Solutions
To achieve carbon neutrality and enhance energy security, Mongolia is exploring a transition toward hybrid energy solutions integrating small modular reactors (SMRs) and renewable energy sources. This study assesses the feasibility of a grid-connected hybrid energy system that combines coal, solar photovoltaic (PV), wind turbines, battery energy storage systems (BESS), and SMRs to reduce greenhouse gas emissions and improve energy reliability.

The Fractal Blueprint: Soil Pores, Symmetry, and Climate Mitigation
Soil is a critical component of terrestrial ecosystems, directly influencing global biogeochemical cycles. Despite its importance, the complex architecture of soil pores and their impact on greenhouse gas emissions remain poorly understood. This perspective aims to address this gap by applying discrete symmetry and symmetry-breaking concepts through fractal geometry to elucidate the structural and functional complexities of soil pores. We highlight how fractal parameters can quantify the self-s…

Can you trust climate information? How and why powerful players are misleading the public
Ten years ago, the world committed itself to keeping global warming well below 2°C (and preferably below 1.5°C) above the pre-industrial era. This would be done by reducing greenhouse gas emissions significantly by 2030 and ending all human-caused greenhouse gas emissions by 2050. This was the time of promises, with 195 countries signing up to the legally binding, global treaty on climate change, the Paris Agreement.

Reconfigurable Battery Systems for Enhanced Fast Charging in Electric Vehicles
The adoption of electric vehicles (EVs) is rapidly growing as a key solution to reducing greenhouse gas emissions. However, prolonged charging times remain a significant barrier to widespread EV usage, especially for individuals without access to fast charging infrastructure. This paper explores the potential of reconfigurable battery systems to reduce EV charging times without compromising battery life. We propose innovative battery pack configurations that dynamically adjust the arrangement o…

Detection, attribution, and modeling of climate change: key open issues
The CMIP global climate models (GCMs) assess that nearly 100% of global surface warming observed between 1850-1900 and 2011-2020 is attributable to anthropogenic drivers like greenhouse gas emissions. These models also generate future climate projections based on shared socioeconomic pathways (SSPs), aiding in risk assessment and the development of costly Net-Zero climate mitigation strategies. Yet, the CMIP GCMs face significant scientific challenges in attributing and modeling climate change,…

Climate impacts and monetary costs of healthy diets worldwide
About 2.8 billion people worldwide cannot afford the least expensive foods required for a healthy diet. Since 2020, the Cost and Affordability of a Healthy Diet (CoAHD) has been published for all countries by FAO and the World Bank and is widely used to guide social protection, agricultural, and public health and nutrition policies. Here, we measure how healthy diets could be obtained with the lowest possible greenhouse gas (GHG) emissions, in ways that could further inform food choice and poli…

Fact: Taking a BC Ferry from Metro Vancouver to Vancouver Island is a High CO2 experience, though if it's a full ferry, it's not terrible (~5kgCO2/passenger)
By 2031, BC Ferries will have replaced 18 ferries (big and small!) in 15 years, and nearly all will be 100% electric-ready.
They just announced they're doing the big ships next.
"Built with diesel-battery hybrid propulsion systems and designed with the capability to operate on full electric power in future, the NMVs are expected to significantly reduce greenhouse gas emissions, improve fuel efficiency, and lower underwater radiated noise to better protect marine life. With greater capacity than the vessels they replace, the NMVs will offer more space for vehicles and passengers and upgraded amenities, supporting a more reliable and comfortable travel experience.”
The age of fossil fuels is ending. Any politician or lobbyist who says otherwise is either not paying attention, or bought.

The role of Projects of Common Interest in reaching Europe's energy policy targets
The European Union aims to achieve climate-neutrality by 2050, with interim 2030 targets including 55% greenhouse gas emissions reduction compared to 1990 levels, 10 Mt p.a. of a domestic green H2 production, and 50 Mt p.a. of domestic CO2 injection capacity. To support these targets, Projects of Common and Mutual Interest (PCI-PMI) - large infrastructure projects for electricity, hydrogen and CO2 transport, and storage - have been identified by the European Commission. This study focuses on PC…
