Energy saving lightbulbs are harder to find and more expensive in low-income U.S. communities than in more affluent areas, according to a new study from the University of Michigan. The cost for households to upgrade from incandescent to LED bulbs, for example, was two times higher in low-income neighborhoods.

Reports in recent years that marine protected areas (MPAs) aren’t effective in saving coral reefs from the damaging effects of global climate change have led some to argue that such expensive interventions are futile. But a study that spanned 700 kilometers of the eastern Caribbean reveals that MPAs can, indeed, help coral reefs.

A new satellite that measures and provides detailed carbon balance information is one of the most important new tools in carbon measurement since infrared light, believe researchers from the University of Copenhagen. The researchers expect the satellite to be a valuable tool for the UN’s work on climate change related to the Paris climate accord.

A new MIT study reports that if China follows through with its international pledge to reduce carbon dioxide emissions, every one of its provinces will experience benefits to air quality and human health, with associated monetary savings that could offset the total cost of implementing the climate policy.

Western Canadian grain farmers may reap financial losses in the billions in years to come, unless the country’s railroads ramp up their capacity to get crops to market, says a University of Alberta expert.

We now know that the underwater world is anything but silent. In fact, today’s researchers are concerned that underwater noise produced by humans is distracting, confusing — and even killing — aquatic animals.

For two decades, environmentalist Jürgen Resch has locked horns with Germany’s mighty automobile industry, the backbone of Europe’s most powerful economy. And Resch has shown that he will do what Berlin’s top politicians won’t: hold carmakers — and German municipalities — to the letter of the law when it comes to the high levels of pollution spewed from diesel automobiles. His indispensable ally in this against-the-odds mission has been Germany’s court system.

Companies looking to reduce their environmental impact without negatively affecting profits may want to consider increasing their investment in green technology and other sustainable IT solutions, according to a new study on information technology and sustainability published in Production and Operations Management.

Putting a price on carbon, in the form of a fee or tax on the use of fossil fuels, coupled with returning the generated revenue to the public in one form or another, can be an effective way to curb emissions of greenhouse gases. That’s one of the conclusions of an extensive analysis of several versions of such proposals, carried out by researchers at MIT and the National Renewable Energy Laboratory (NREL).

The recent death of the last male Northern white rhinoceros — and the imminent extinction of the vaquita porpoise — is a stark reminder we are not going to win every battle to save endangered species in the wild. We can rescue some from total extinction — and have already — but only with the help of zoos and aquariums.
