Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.

Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel heterostructured photocatalyst using titanium and copper, two abundant and relatively inexpensive metals, for the conversion of CO 2 into CH 4. Apart from its CO 2 conversion capabilities, the proposed photocatalyst has other benefits.

Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime. This unexpected phenomenon suggests sulfur dioxide emission reductions are less efficient than expected for cutting sulfate aerosols. These trends are expected to continue.
