The Energy Wars Come to Louisiana: Carbon Capture, Removal, and Storage Projects Face New Hurdles in the Pelican State
Until recently, Louisiana was the darling of the carbon capture, removal, and storage industry. Due to its history of oil and gas production, the state has a fairly extensive carbon dioxide pipeline network, and ideal geology for storing carbon dioxide. For those reasons, federal incentives to advance point source capture of carbon dioxide (e.g., at […]

Biofilms might be key to supporting the health of space missions
by
A close-up of the roots of a hydroponic plant. New research appears to signal a reframing (or the need for one) in relation to how biofilms are viewed in space biology, and the previously overlooked role they might play in ensuring the health of space missions. On Earth, microbial biofilms — dense, self-organising communities of […]

Explainer: Why gas plays a minimal role in China’s climate strategy
Ten years ago, switching from burning coal to gas was a key element of China’s policy to reduce severe air pollution. However, while gas is seen in some countries as a “bridging” fuel to move away from coal use, rapid electrification, uncompetitiveness and supply concerns have suppressed its share in China’s energy mix. As such, […]

New Sabin Center Report and Online Resource: Navigating State Law in Local Climate Action
Local governments are leaders in the fight against climate change: they reduce community-wide greenhouse gas emissions, promote renewable energy resources, and otherwise advance climate mitigation and adaptation goals. But even as many local governments have already demonstrated their capability to tackle the climate crisis, state governments can hinder those efforts by preempting local laws. Today, […]

Adopting low-cost ‘healthy’ diets could cut food emissions by one-third
Choosing the “least expensive” healthy food options could cut dietary emissions by one-third, according to a new study. In addition to the lower emissions, diets composed of low-cost, healthy foods would cost roughly one-third as much as a diet of the most-consumed foods in every country. The study, published in Nature Food, compares prices and […]
