The long-term aspirational goal of the Paris Agreement on climate change is to cap global warming at 1.5 degrees Celsius above preindustrial levels, and thereby reduce the frequency and severity of floods, droughts, wildfires, and other extreme weather events. Achieving that goal will require a massive reduction in global carbon dioxide (CO2) emissions across all economic sectors. A major roadblock, however, could be the industrial sector, which accounts for roughly 25% of global energy- and process-related CO2 emissions—particularly within the iron and steel sector, industry's largest emitter of CO2.

Since the early 1990s, the small blue Energy Star label has appeared on millions of household appliances, electronics and even buildings across the United States. But as the Trump administration considers terminating some or all of the program, it is worth a look at what exactly this government-backed label means, and why it has become one of the most recognizable environmental certifications in the country.

Perovskite has broad application prospects in solar cells, light-emitting diodes (LEDs), and detectors due to its high luminescent efficiency and low cost. However, electrons and holes in traditional perovskite materials often struggle to effectively recombine and emit light. As a result, the strongly space-confined method is commonly employed to improve luminescence efficiency. Furthermore, how to enhance the brightness of LEDs and extend their lifespan has become a top research priority in this field.

Today, 2.2 billion people in the world lack access to safe drinking water. In the United States, more than 46 million people experience water insecurity, living with either no running water or water that is unsafe to drink. The increasing need for drinking water is stretching traditional resources such as rivers, lakes, and reservoirs.

Evidence suggests that several of the catastrophic wildfires that struck Los Angeles earlier this year may have been sparked by electric utility infrastructure. As utilities prepare for record infrastructure demand driven by electrification, data centers, and renewables, the cost of inaction in the face of rising wildfire risk is mounting.
