Air quality model simulating photochemical formation of pollutants: the Sao Paulo Metropolitan Area, Brazil
The main sources of ozone precursors in the atmosphere of the Sao Paulo Metropolitan Area (SPMA) in Brazil are emissions from gasoline-, ethanol-, and diesel-powered vehicles. Ozone is a significant air quality problem in the SPMA. To come into compliance with the National Ambient Air quality Standard for Ozone, emission reduction policies must be established. An adequate emissions inventory and ...

Compressed Air Pneumatics Demonstrated in Calgary
At the Petroleum show in Calgary, our Canadian distributor OilPro demonstrated CAP3. CAP3 (Compressed Air Pneumatics) replaces methane emission from pneumatic devices with compressed air. The annual U.S. emission reduction potential of CAP3 is about 40 million tons of CO2- equivalent (equivalent to taking 9.5 million cars off the road). Wholehearted thank you for everyone involved! ...

Investigating weekend air quality observations with the aid of Fourier analysis in Athens, Greece
Weekend air quality is analysed with the aid of Fourier analysis, in order to reveal time-series structures for Athens, Greece. For this reason, an appropriate analysis of a 10 year record from 1990–1999 of air quality data from the monitoring network in Athens is carried out for two specific monitoring sites. The aim of the paper is to investigate the temporal pattern of observations in order to ...

China's energy outlook to the year 2030
This study gives a long-term energy outlook in China by an econometric method. In the coming 30 years, China's GDP growth will be around 7% annually, and the continuation of rapid economic growth could result in a number of difficult issues such as energy security, environment protection and CO2 emission reductions. China should solve these problems through its own efforts. The first step is to ...

Potential CO2 reduction through restructuring the Jordanian utility sector
This study attempts to predict the potential CO2 reduction due to pre–proposed future restructuring scenarios toward clean generation technologies for the Jordanian utility sector. The calculation is based on CO2 emission for unit electricity generated and the changing type of fuel percentages for electricity generation in Jordan. It was found that such restructuring will significantly contribute ...

Cleaner transport technology most efficient to ensure compliance with 2010 NO2 limit values in Copenhagen, Denmark
An integrated traffic and air quality modelling approach was used to assess the impacts of local abatement measures to study compliance with European Union (EU) air quality limit values for NO2 and PM10. The abatement measures included four scenarios: municipal traffic management, toll ring or road pricing, cleaner transport technology as part of an environmental zone, and maximum effect – a ...

A mixed-integer non-linear programming model for CO2 emission reduction in the power generation sector
Electricity generation is considered to be one of the main contributing sources to the air pollution problem. It is, therefore, important to develop and implement effective control strategies to prevent the expected abrupt increase in emissions from this sector. Any control strategy must be suitable for local implementation and must also be economically viable. The main objective of this paper is ...

Climate Change: Chasing Compliance
The world’s converging energy, environmental, and political stresses present the upstream oil and gas industry with a set of complex challenges that are riddled with unexpected non-linear results and emergent properties. As governments react to climate change concerns, new regulations and changes to existing frameworks emerge at a rapid and confusing pace. As Ottawa stands behind their ...

Observational needs for four-dimensional air quality characterization
Surface-based monitoring programs provide the foundation for associating air pollution and causal effects in human health studies, and they support the development of air quality standards and the preparation of emission reduction strategies. While surface-oriented networks remain a key tool for addressing traditional single pollutant human exposure challenges, these networks in isolation are not ...

4 Ways Cities Benefit from Bus Rapid Transit (BRT)
Around the world, cities are searching for sustainable ways to transport residents quickly, efficiently, and safely throughout their streets. One such solution is bus rapid transit (BRT), a city-based, high-speed bus transit system in which buses travel on dedicated routes. BRT is already widely implemented in both the developed and developing worlds. New research shows that BRT can reduce ...

Effects of CO2 emission reduction strategies on air pollution
Emission reduction strategies for air pollutants such as SO2 and Ox as well as for greenhouse gases (GHGs) usually do not consider the interdependencies between emission reduction measures. Taking into account the relevant energy, environmental and political framework it is the objective of this study to determine the influence of CO2 emission reduction strategies for the German state of ...

Real-Time Monitoring of the Endangered Northern Right Whale - Case Study
BACKGROUND In 2006, Excelerate Energy requested a permit in order for its Deepwater port, Northeast Gateway, to be connected to the New England gas grid through a subsea interconnect. The permit was required because ships entering the port delivering LNG introduced a higher risk of vessels striking mammals, in particular the endangered Northern Right Whale. CHALLENGES In the face of energetic ...

Energy and Environment in the European Union
Introduction Energy gives personal comfort and mobility to people, and is essential for the generation of industrial, commercial and societal wealth. On the other hand, energy production and consumption (including heat and electricity production, oil refining and final uses in households, services, industry and transport) place considerable pressures on the environment. These pressures include ...

The latest information about scrubber installation
IMO 2020 marine fuel regulations result in “very long waiting lists at some shipyards,”, especially in China, for scrubber installation on ship vehicles. The thing is that wet air scrubbers are made to order, and their manufacture generally takes about six months. After the creation, the wet scrubbers are held by shipyards, where queues for installation have now built up. It should ...

Revealing the costs of air pollution from industrial facilities in Europe
This European Environment Agency (EEA) report assesses the damage costs to health and the environment resulting from pollutants emitted from industrial facilities. It is based on the latest information, namely for 2009, publicly available through the European Pollutant Release and Transfer Register (E-PRTR, 2011) in line with the United Nations Economic Commission for Europe (UNECE) Aarhus ...

Case study - Printing: RTO solution
Overview A flexographic converter needed to expand its business by adding an 8-color CI printing press to its existing press lines, and planned to add a second press later. The increase in emissions and flow from the new press was beyond the capacity of the existing 10-year old catalytic oxidizer. The customer needed a way to maintain compliance at an affordable cost. Action After a thorough ...

Maritime emissions treatment system (METS)
In January 2014, the California Air Resources Board (CARB) began enforcement of the "Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port" Regulation, commonly referred to as the At-Berth Regulation. Covering all six ports in California, the At-Berth Regulation requires a 50% reduction in emissions from auxiliary diesel engines ...
