Pitkin County is swapping old gas boilers for a sleeker electric heat pump system at two key buildings. Instead of burning fuel to make heat, these pumps move existing warmth from the air outside into the rooms, cutting energy waste. The county expects this switch to slash greenhouse gases from its
People are looking for ways to make engines work better and pollute less. One idea is to use two different fuels at the same time. This is called RCCI, or Reactivity Controlled Compression Ignition. It uses a mix of fuels with different properties to burn more efficiently and produce fewer harmful g
The goal was to find the best settings for a special engine. This engine uses a mix of fuels to burn cleanly and efficiently. It combines a high-reactive fuel, made from 30% mahua biodiesel and diesel, with a low-reactive fuel, ethanol. The engine can switch between different loads and ethanol share
During the COVID-19 lockdown, global shipping activities were significantly reduced. This provided a unique opportunity to study the impact of reduced marine traffic on nitrogen dioxide (NO 2 ) pollution, a key indicator of shipping emissions. Satellite data from TROPOMI showed a substantial decre
The Biden administration is walking a tightrope on air pollution. They've partially revived stricter rules for some polluting facilities, but left others with the looser standards set by the Trump era.
