A new study published in Construction and Building Materials has found that enhancing the use of supplementary cementitious materials (SCMs) is an effective strategy for lowering the cement industry's carbon footprint. In South Korea, a strategic roadmap was established to increase the SCM content in ordinary Portland cement
Air pollution
Researchers from the Department of Mechanical Engineering have published a study on a downdraft gasifier that aims to reduce diesel dependency and emissions in rural areas by using producer gas as a cleaner alternative fuel. The study, which involves a modified double-cylinder diesel engine, demonstrates a substantial reduction in diesel
Air pollution
Researchers from the Department of Mechanical Engineering at the Walter Scott Jr College of Engineering have conducted a study on natural gas emissions reduction through engine vent gas recirculation. The study focuses on evaluating three engine types, including the Caterpillar G3516 ULB, Caterpillar CG137-8, and Copper Bessemer GMV-4TF. The investigation
Air pollution
Motorists are taking legal action against over a dozen car manufacturers, claiming that they installed "prohibited defeat devices" (PDDs) in diesel vehicles made from 2009 onwards. These devices would allow the vehicles to detect when they were being tested and alter their emissions to meet regulations, but would

Attorneys General from Washington and 21 other states, along with nine local governments, have submitted a comment letter to the U.S. Environmental Protection Agency (EPA) opposing its proposal to rescind the 2009 finding that greenhouse gas emissions endanger public health and welfare. The coalition argues that rescinding the finding
Air pollution
New research from the Institute for Environmental Engineering has provided a crucial breakthrough in addressing a significant pollution issue in the semiconductor manufacturing process. The study focused on the emission of nitrous oxide (NOx) in burn-wet and plasma-wet local scrubbers (LSCs), which is a major environmental concern in the industry.
Air pollution
The Colorado Air Quality Control Commission has adopted health-protective benchmarks for benzene, ethylene oxide, formaldehyde, hexavalent chromium compounds, and hydrogen sulfide, meeting a legislative mandate and providing science-based guidance for evaluating long-term exposure to priority air toxics. The benchmarks identify levels of pollutants below which adverse health effects are not
Air pollution
The United States faces significant environmental, safety, and economic challenges related to transportation. Representative Jared Huffman and Senators Edward Markey, Alex Padilla, Jeff Merkley, and Bernie Sanders have introduced the Generating Resilient, Environmentally Exceptional National (GREEN) Streets Act to address these issues. The legislation aims to reduce greenhouse gas emissions,
Air pollution
Washington state, along with a coalition of other states and local governments, has filed a comment letter opposing the U.S. Environmental Protection Agency's (EPA) proposal to undo its landmark 2009 finding that greenhouse gas emissions endanger public health and welfare by driving climate change. The proposal, announced
Air pollution
The Kumho Petrochemical Group's major affiliates have launched a range of initiatives to address the climate crisis by cutting greenhouse gas emissions. These initiatives include the use of carbon capture, utilization, and storage (CCUS) technology, recycling of waste as a raw material, and alignment with the government'
Air pollution
The GENERATING Resilient, Environmentally Exceptional National (GREEN) Streets Act, a new legislation introduced by Senator Edward J. Markey (D-Mass.) and Representative Jared Huffman (CA-02), aims to reduce greenhouse gas emissions and improve transportation infrastructure in the United States. The bill would establish goals to reduce emissions and vehicle miles traveled
