Decarbonizing the Indian power sector by 2037 : evaluating different pathways that meet long-term emissions targets
The Indian government is aiming to reduce carbon emissions intensity in the power sector through incentivizing the addition of renewables sources into the grid. India has set the goal that at least 40% of total power capacity must be non-fossil fuel-based by 2030 with more ambitious goals expected …

Aircraft emissions reductions through improved operational performance : challenges, opportunities and policy implications
Aircraft are a significant source of emissions whose impact on local air quality and global climate change is expected to increase as the aviation industry continues to grow. Operational improvements are an attractive alternative for emissions reductions, because in addition to the environmental …

A hydrogen fueling station in 2005?-- will it happen : how do we get from here to there?
… appear promising for major reductions in local emissions and significant decreases in greenhouse gas emissions from the transportation sector. Efficient fuel cells require hydrogen fuel. If the hydrogen is produced from primary fossil fuel sources, the greenhouse gas benefits are much …

Real time analysis of atmospheric single particles in urban environments using aerosol time of flight mass spectrometry
… Furthermore, 79% of the EC was apportioned to local emissions and 21% to continental transport. The carbonaceous particle types were compared with quantitative measurements from other instruments, and while direct correlations using particle counts were poor, scaling of the ATOFMS counts …

Impacts of long-range transport of biomass burning on air quality in Texas.
… were conducted to measure the impact of local emissions and transported pollution on air quality in Texas cities. The inter-site comparison of VOCs and trace gases across the San Antonio metropolitan area revealed significant geospatial and temporal variabilities in emissions and …

New insights into understanding urban traffic emissions using novel mobile air quality measurements in the Breathe London pilot study
… measurements to better understand urban traffic emissions. As part of the Breathe London project, two Google Street View Cars (based at the National Physical Laboratory) were fitted with air quality monitoring instrumentation and were driven across London over approximately a one year period. …

The transport of pollutants over South Africa and atmospheric sulphur in Cape Town
… quality management has focussed on identifying local sources and reducing the local emissions of sulphur. Meanwhile, the transport of sulphur pollutants from areas outside Cape Town can contribute to ambient sulphur concentrations. This work studies the transport of sulphur pollutants over South …

The transport of PM10 over Cape Town during high pollution episodes
… high concentrations of PM10 over Cape Town to local sources, neglecting the influence of remote sources. The present study investigates the influence of remote and local pollution sources to PM10 episodes over the city. The study analysed observations from Cape Town’s air quality monitoring …

Large-scale production of oxymethylene dimethyl ethers
… combustion, which can strongly reduce NOx emissions. Besides reducing local emissions, OME can strongly reduce CO2 emissions by replacing fossil diesel fuel if their production is based on sustainable methanol. Various process concepts for their production were proposed and investigated, …

New Opportunities in Crowd-Sourced Monitoring and Non-government Data Mining for Developing Urban Air Quality Models in the US
… (EPA) aims to reduce air pollution by regulating emissions and continuously monitoring air pollution levels. Local communities also benefit from crowd-sourced monitoring to measure air pollution, particularly with the help of rapidly developed low-cost sampling technologies. The shift from relying …

Retrieval of trace gases vertical profile in the lower atmosphere combining. Differential Optical Absorption Spectroscopy with radiative transfer models
… ozone in the atmosphere is determined both by local emissions and non-local chemical and dynamical processes (i.e. diffusion and transport at various scales) that greatly impact on their vertical and temporal distribution: thus a tool to resolve the vertical profile information is really …
