A web-based open emissions calculator
Many organisations and governmental agencies offer online calculators to calculate the carbon footprint of industrial activities. Furthermore, airline companies offer online tools to estimate carbon footprint and promote the purchase of carbon offsets in order to make the trip carbon neutral. This paper presents a free online emissions calculator that computes various emissions-related statistics ...

GHG Protocol Initiative - A step forward in GHG emissions calculations
With the GHG Protocol 60 companies will look comprehensively at the impact of their corporate value chains, reports Envido. On January 20th, the GHG Protocol Initiative announced that 60 companies had started measuring the greenhouse gas emissions of their products and supply chains by testing a new global framework, part of the Greenhouse Gas Protocol Initiative. Developed by the World Resources ...

An approach for road air emissions calculation: Portuguese case-study
A methodology to estimate road transportation emissions was developed with the main objective of improving emission estimates for those pollutants that are most dependent on the vehicle class and abatement technology. Emissions were estimated with a detailed level of disaggregation allowing the evaluation of measures aiming key source groups rather than road traffic in general. Those measures ...

Emission behaviour of modern heavy duty vehicles in real world driving
Within a national and two international research projects, a vehicle emission model was developed, which calculates emissions in real world driving from the engine emission maps by simulating engine power and engine speed. Influences of transient load changes on the emission level are taken into consideration by special functions. Model parameters are gained from a common measurement protocol on ...

Development of emission factors for the control of lead and other metals during bridge construction work
This study was conducted to develop emission rates and emission factors for lead and other metals during abrasive blasting and power tooling operations. Emission factors are useful in controlling process emissions since it allows for the extrapolation of emissions from one process to another related process. Area samples were collected inside the bridge containments and emission rates were ...

European Union CO2 emissions: different accounting perspectives
The aim of this technical report is to explain to a wider audience the concepts and methodologies behind different air emission accounting perspectives and the resulting emissions data at the EU level. In brief, there are three of these different accounting perspectives: territorial, production and consumption. Three perspectives on air emissions The territorial perspective considers emissions ...

A constant eye on emissions
Due to increasingly rigorous requirements for regulatory and permit compliance, organisations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

The road not chosen
Analysis of data for historical consumption of the most important energy sources and carbon emission leads to a method to calculate the carbon emission with another fuel mix than the actual one. It is shown that a continued growth of nuclear power could have replaced the whole Kyoto process.Keywords: economy, ecology, nuclear power, nuclear energy, Kyoto protocol, carbon emissions, road not ...

Conservation carbon: A new voluntary market mechanism to protect forests
Addressing deforestation is critical to mitigating climate change, and also has the potential to deliver significant social benefits to local communities and additional environmental co-benefits. Any consideration of forests and deforestation under the UNFCCC or Kyoto Protocol is expected to occur within this framework of emissions and emission reductions calculated against a baseline or ...

A GIS based air quality system for the Apulia region, southern Italy
A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

Enterprise Carbon Accounting: The quest for unprecedented transparency
Enterprise carbon accounting (ECA) is an essential requirement for companies and will likely become necessary due to government legislation. No longer is it permissible for a company to look within its borders, but it must look at its overall environmental responsibilities and accurately gauge and measure carbon production and emission caused by its very existence. Financial data must be directly ...

CO2 impacts of transporting UK’s recovered paper and plastic bottles to China
Exports of recovered materials for recycling overseas have grown at a rapid pace over the past decade. In 2007, 4.7 million tonnes of recovered paper and half a million tonnes of recovered plastics were exported. The principal destination for these exports was China. The environmental benefits of domestic recycling are well understood. However, one question often asked in respect of exports is ...

Air quality photochemical study over Amazonia Area, Brazil
This work presents the results of a photochemical modelling system composed of MM5–SMOKE–CMAQ on Brazilian Amazonia area, been a pioneered implementation task. These results focus on the biogenic and biomass burning emissions and the impact of these emissions on regional air quality. Global and local anthropogenic emissions data, satellite–derived biomass burning inventories, ...

Refrigerant compliance includes calculating carbon emissions
If you manage a facility using a refrigeration and air-conditioning (RAC) system or heating, ventilation and air conditioning (HVAC-R) system, it’s time to comply with federal and state environmental laws regarding carbon emissions. To help reduce greenhouse gases, the law requires calculating carbon emissions. This means monitoring, collecting data and performing extensive reporting of CO2 ...

Project - Yanbu Refinery - Oil and Gas
Capacity: 400,000 Barrels per day A major oil and gas operator in KSA contracted CMC to deliver and certify 4 PEMS for compliance on their refinery stacks. A SmartCEMS PEMS was started-up to record the operating and emission data in June of 2013 for all of the units. The data acquisition system consisted of a data historian integrated with the DCS. The system utilizes the signal from the gas flow ...

Economic damage control for greenhouse gas emissions
Future emissions of trace gases are intrinsically linked to economic growth and abatement policies, which in turn, are governed by expectations of greenhouse damages. Trace gas indices that depend upon future emissions can be calculated either on the basis of emissions scenarios, such as those devised by the IPCC, or using optimal control techniques where the trade-off between damages and ...

Understanding GHG verification requirements
Many organizations are required to report greenhouse gas (GHG) emissions to the U.S. EPA mandated by the Mandatory Reporting Rule (MRR). Effective December 29, 2009, large sources and suppliers in the United States will begin collecting data on January 1, 2010 and report GHG emissions to EPA by March 31, 2011. Similar to the EPA MRR, many states also have mandatory reporting requirements. The ...

Modelling emission, concentration and deposition of sodium for Poland
The aim of this paper was to calculate natural and anthropogenic emission of Na+ and to estimate, with the FRAME model, annual air concentration and deposition of Na+ for the domain covering Poland. Calculations of natural emissions included marine emission and wind blown dust from land. Anthropogenic emission was calculated for both point and area sources. Emission maps were used in fine ...
