Researchers at the University of Michigan have mapped the annual flow of steel in the US, with the goal of achieving a detailed understanding of the flow to target increased material efficiency and the development of the circular economy. The steel industry accounts for 30% of global industrial greenhouse gas emissions (GHG).
Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO 2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois. The carbon-related costs of converting the land to sugarcane fields were included in the analysis.
EVA serves as a platform to showcase the results of the work at TUM CREATE, a joint research program by Technische Universität München (TUM) and Nanyang Technological University (NTU). Besides the cabin cooling system, EVA’s innovative seats provide a maximum comfort for both the driver and passengers driving in humid tropical climate.

Anthropogenic climate change confronts humanity with a challenge: How can we keep warm now as we try to prevent our world from overheating in the future? A Small Country with Large Heating Needs Big problems demand big solutions, and there is perhaps no bigger 21st-century problem than climate change.
Combating climate change demands that humanity kick its addiction to fossil fuels. And he proceeds to back up this new assertion with solid statistical analysis. Achieving that will require a near total shift from internal combustion motors to electric traction motors for transportation. And robotaxis are leading the charge.
