Methane emissions from the distribution and use of natural gas across U.S. cities are 2 to 10 times higher than recent estimates from the Environmental Protect Agency, according to a new study from the Harvard John A. Paulson School of Engineering an.....»»
Areas with more illegal market opportunities more likely to be targeted by organized crime, study shows
Communities with higher-than-average illegal market opportunities (proxied by drug-related activities) are more likely to be targeted by organized crime groups, a new study shows......»»
Net zero plans show limited climate ambition on "residual" emissions
New research by the University of East Anglia (UEA) reveals what countries think will be their most difficult to decarbonize sectors when they reach net zero, with agriculture expected to be responsible for the largest remaining emissions......»»
For sustainable aviation fuel, researchers engineer a promising microorganism for precursor production
Sustainable aviation fuels made from renewable sources of carbon could reduce carbon dioxide emissions and help to mitigate climate change. Isoprenol is a chemical involved in the production of a jet biofuel blendstock called 1,4-dimethylcyclooctane.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
Report: Governments are falling short on promises of effective biodiversity protection
A new analysis of the world's largest 100 marine protected areas (MPAs) published in Conservation Letters suggests that governments are falling short on delivering the promise of effective biodiversity protection due to slow implementation of managem.....»»

Walking in African cities can be a miserable experience: Study shows planners ignore needs of pedestrians
African cities aren't welcoming places for pedestrians. Yet walking is free and, given the shortage of decent public transport, it's often the only way for people to move around. More than 70% of Africa's urban population of about 609 million walk da.....»»
A photocatalyst for sustainable syngas production from greenhouse gases
Researchers have developed a novel photocatalyst, named Rh/InGaN1-xOx, which is a nanoarchitecture consisting of rhodium nanoparticles anchored on oxygen-modified indium gallium nitride nanowires grown on silicon substrates......»»

Discharge of scrubber water into the Baltic Sea is responsible for hundreds of millions in costs
Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study from Chalmers University of Technology, Sweden, shows that these emissions caused pollution corresponding to socioeconomic costs of more than €680 milli.....»»
Team describes MXene-supported PtCo bimetallic catalyst for hydrogen evolution in acidic conditions
Hydrogen energy is considered a promising solution with high energy density and zero pollution emissions. Currently, hydrogen is mainly derived from fossil fuels, which increases energy consumption and greenhouse gas emissions, hindering efforts to a.....»»
As business districts evolve post-pandemic, repurposing old or empty spaces should be on the drawing board
The COVID-19 pandemic and the hybrid work patterns it fostered have changed the way we think about office space, and central business districts in general. While fears of urban center "ghost towns" may have been premature, many cities around the worl.....»»
Turbid waters keep the coast healthy, finds study
To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study conducted by a Dutch-Chinese team of researchers and published in Nature Ge.....»»
Nanoparticle catalysts convert carbon dioxide to carbon monoxide to make useful compounds
As a greenhouse gas, carbon dioxide (CO2) contributes to climate change as it accumulates in the atmosphere. One way to reduce the amount of unwanted CO2 in the atmosphere is to convert the gas into a useful carbon product that can be used to generat.....»»
Cyclone bears down on flood-hit Kenya, Tanzania
