There is a consistently high level of public support across nations for a global carbon tax if the tax policy is carefully designed, according to a survey of people in the United States, India, the United Kingdom, South Africa and Australia.

A low-cost, versatile type of charcoal known as biochar can be tailored for specific uses including treating water, removing contaminants from soil and even storing carbon, according to new research by University of Alberta scientists.

Keeping road pavement in good shape saves money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a Rutgers-led study.

U of T Engineering researchers have examined dust from homes in Fort McMurray, Alta., for evidence of harmful toxins left in the aftermath of the devastating 2016 wildfire. 

After early reports of microplastic pollution in our oceans and beaches sounded the alarm, the global scientific community intensified its focus into this area. 

A study led by researchers at the ARC Centre of Excellence for Coral Reef Studies at James Cook University found fish become anxious and more cautious when water quality is degraded by sediment, an effect that could stunt their growth and damage their health.

A new Tel Aviv University study describes a process to make bioplastic polymers that don't require land or fresh water — resources that are scarce in much of the world. The polymer is derived from microorganisms that feed on seaweed. It is biodegradable, produces zero toxic waste and recycles into organic waste.

Tropical forests are one of the largest natural sources of the greenhouse gas nitrous oxide (N2O), and a tiny insect may play a big role in how those emissions are spread out across the landscape.

Every bus used for public transportation in California will be a zero emissions vehicle by 2040 as the result of a new initiative approved this week by the Air Resources Board.

A computational modeling method developed at the University of Pittsburgh may help to fast-track the identification and design of new carbon capture and storage materials for use by the nation’s coal-fired power plants.
