How Europe’s Night Trains Came Back From the Dead

An anonymous reader quotes a report from CNN: [O]ver the past decade, much of Europe’s night train network has been cut. 2013 and 2014 saw the culling of lines from Paris to Madrid, Rome and Barcelona; Amsterdam to Prague and Warsaw; and Berlin to Paris and Kiev. For many, it seemed the end of the line was nigh. But recently there…

1% of People Cause Half of Global Aviation Emissions, Study Says

Frequent-flying “super emitters” who represent just 1% of the world’s population caused half of aviation’s carbon emissions in 2018, according to a study. From a report: Airlines produced a billion tonnes of CO2 and benefited from a $100bn subsidy by not paying for the climate damage they caused, the researchers estimated. The analysis draws together data to give the clearest global…

Spinach Gives Fuel Cells a Power Up

Researchers at the Department of Chemistry, American University, used spinach to make a carbon-rich catalyst that can be used to improve the performance of fuel cells and metal-air batteries. IEEE Spectrum reports: The spinach was a used a precursor for high-performance catalysts required for the oxygen reduction reactions (ORRs) in fuel cells. Traditionally, fuel cells have used platinum-based catalysts, but not…

Rethinking your pension may just be the greenest thing you can do

New design principles for spin-based quantum materials

As our lives become increasingly intertwined with technology—whether supporting communication while working remotely or streaming our favorite show—so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint—and consume 200 terawatt hours of energy each year, greater than the annual energy consumption of Iran. To balance ecological concerns yet meet…

Google Reverses Lifelong Carbon Emissions To Fight Climate Change

A few months after Microsoft pledged to undo by 2050 the climate harm it’s done to the atmosphere by emitting carbon dioxide into the atmosphere, Google said it’s already done so. “We have eliminated Google’s entire carbon legacy,” Chief Executive Sundar Pichai said Monday in a blog post. From a report: Carbon dioxide, which can trap heat from the sun in…

Changing how we make solar panels could reduce their carbon emissions

Although solar panels are a source of renewable energy, making them has an environmental impact.
