How we reduce CO2 emissions in the built environment is changing – with focus moving from energy efficiency to reducing embodied carbon, according to UNSW’s Philip Oldfield.

If the region surrounding Chicago — North America’s largest freight hub — shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new Northwestern University-led study.

Carbon capture is a promising method to help slow climate change.

The University of Colorado Boulder’s Weimer Lab has introduced an efficient and economical method to use renewable energy to produce fuel, opening doors to clean and sustainable energy sources for a wide array of industries, including transportation, steelmaking and ammonia production.

Efficient and cheap batteries that can also capture harmful emissions could be right around the corner, thanks to a new system that speeds up the development of catalysts for lithium-CO2 (Li-CO2) batteries. 

Freshwater ecosystems account for half of global emissions of methane, a potent greenhouse gas that contributes to global warming. 

A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures.

One of the most popular strategies to increase energy efficiency and reduce pollution in homes — which are responsible for approximately 10 percent of greenhouse gas emissions — is the transitioning from gas to electric stoves.

Understanding why existing hydrogen fuel cell prototypes degrade can pave the way for more durable cells. 

The activity level of six bat species was significantly reduced at solar farm sites, researchers have observed.
