(Press-News.org) Montreal, 10 December 2012—Right now, if businesses or environmental officials need to estimate the impact of different greenhouse gas (GHG) reduction measures in one country or region of North America compared to another, they face multiple GHG reporting regimes with varying levels of detail and complexity.
In response, Canada, Mexico and the United States are seeking to improve the comparability of emissions data in North America to advance domestic carbon emissions objectives, standards, regulations and policies by 2015, as part of the Commission for Environmental Cooperation (CEC) Council's strategic priorities.
In North America, trinational climate policy cooperation to reduce such emissions would ultimately depend upon comparable GHG emissions data and information from each country.
Working through the CEC, the countries have taken an important first step in looking at the state of comparability of emissions data at national and subnational levels with the completion of a background report: Assessment of the Comparability of Greenhouse Gas and Black Carbon Emissions Inventories in North America. To access the full report, click here.
The report documents how, at present, North America features multiple GHG-reporting systems, both voluntary and mandatory, at national and subnational levels, and with varying degrees of detail and complexity. GHG reporting requirements for industrial sources, including sector coverage, vary by jurisdiction. The report also looks at black carbon, which is a short-lived climate forcer, an airborne fine aerosol particle that doesn't last long in the atmosphere but is a potent source of human-induced climate change. Combustion processes are a primary source of black carbon emissions.
In the next few weeks, a technical group made up of representatives of the three countries will use the results from this CEC report when they meet to draw up recommendations to North America's three environment ministers.
Facts and figures from the report include:
At least five Canadian provinces or territories, 31 states in the United States and ten states in Mexico have completed GHG inventories independent of their respective national inventories (page 25).
Energy represents the largest source category of GHG emissions for each country (page 4).
The US EPA has developed a framework for producing a black carbon (BC) inventory, including emission factors for specific sources. Some of these factors are already being used by the Canadian and Mexican governments. Combustion of fossil fuel, wood-burning stoves, forest fires and prescribed burning are amongst the sources of black carbon (for black carbon sources, see Table 3 on page 13).
Canada and the United States produce more detailed GHG reports than Mexico, due to Mexico's status as a non-Annex I country, as per the United Nations Framework Convention on Climate Change (UNFCC) guidelines (page 8).
A number of differences were identified for specific emission sectors and sources among the US, Canadian, and Mexican GHG inventories. For example, US emissions from waste incineration are reported under the Energy sector, while in Canada and Mexico, waste incineration is included under the Waste sector (page 19).

About the CEC
The Commission for Environmental Cooperation (CEC) is an intergovernmental organization that supports the cooperative environmental agenda of Canada, Mexico and the United States to green North America's economy, address climate change by promoting a low-carbon economy, and protect its environment and the health of its citizens. The CEC is composed of three bodies: a Council, representing the governments of the three member countries, a Joint Public Advisory Committee (JPAC) that advises the Council and serves as a liaison with the public, and a Secretariat that supports the Council and JPAC and prepares independent reports. The CEC brings together governments, civil society, and businesses to develop innovative North American solutions to global environmental challenges. Find out more at: www.cec.org
CEC initiatives are undertaken with the financial support of the Government of Canada through the Federal Department of Environment, the Government of the United States of America through the Environmental Protection Agency, and the Government of the United States of Mexico, through the Secretaría de Medio Ambiente y Recursos Naturales.

Charlottesville, VA (December 11, 2012). Neurosurgeons at All Children's Hospital/Johns Hopkins Medicine (St. Petersburg, FL) and the University of South Florida Morsani College of Medicine (Tampa, FL) recently achieved excellent physical and aesthetic results in an infant born with extreme macrocephaly due to hydrocephalus. This was accomplished with routine implantation of a ventriculoperitoneal shunt followed by a new operation to stabilize and reduce the size of the baby's head. Both surgeries were performed during the infant's first week of life. The surgeons report ...
KNOXVILLE – Epigenetics – how gene expression is regulated by temporary switches, called epi-marks – appears to be a critical and overlooked factor contributing to the long-standing puzzle of why homosexuality occurs.
According to the study, published online today in The Quarterly Review of Biology, sex-specific epi-marks, which normally do not pass between generations and are thus "erased," can lead to homosexuality when they escape erasure and are transmitted from father to daughter or mother to son.
From an evolutionary standpoint, homosexuality is a trait that ...
For the first time, researchers sequenced DNA molecules without the need for the standard pre-sequencing workflow known as library preparation.
Using this approach, the researchers generated sequence data using considerably less DNA than is required using standard methods, even down to less than one nanogram of DNA; 500 times less DNA than is needed by standard practices.
Libraries are collections of DNA fragments derived from genomic samples using molecular biology techniques specific to the sequencing technology being used. They are laborious, time consuming, and ...
A team of Italian astronomers performed a very difficult measurement for which it was necessary to use the most advanced instrumentation in combination with an unusual technique, so as to involve even the Moon as a natural astronomical mirror. The challenge was the observation of effect occurred during the transit of Venus across the Sun on June 6th, dubbed "Rossiter-McLaughlin effect". This is a phenomenon that occurs when a celestial body passes in front of a star, hiding a part of its rotating surface and that produces a temporary distortion in the profiles of the spectral ...
In order to widen the narrowed airways in patients with chronic obstructive pulmonary disease (COPD), tiotropium bromide (tiotropium in brief) is one of the drugs available that can be prescribed for inhalation. The German Institute for Quality and Efficiency in Health Care (IQWiG) has examined whether tiotropium offers a perceptible advantage to patients compared to a dummy medication (placebo) and to other COPD drugs. In addition, the two currently marketed types of inhaler (HandiHaler and Respimat) for tiotropium (trade name: Spiriva®) were compared.
According to ...
British employers have avoided slashing their budgets for training during the recession because they believe it is vital to their operations, a new study has found.
Researchers analysed figures from various surveys showing that spending in real terms on training fell by only 5% from 2007 to 2009, and has remained steady since. They also spoke to managers from 52 companies and found that almost all remained committed to keeping their training schemes going.
In an article in the December edition of the journal Work, Employment and Society, the researchers say that "a ...
Researchers from the UK and Australia have uncovered a new element of the honeybee's genetic makeup, which may help to explain why bees are so sensitive to environmental changes.
Scientists from the University of Sheffield, Queen Mary, University of London and the Australian National University, have found that honeybees have a 'histone code' – a series of marks on the histone proteins around which their DNA is wrapped in order to fit into the nucleus of a cell. This code is known to exist in humans and other complex organisms in order to control changes in cell development ...
Philadelphia, PA, December 11, 2012 – A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function.
Cell adhesion molecules are the glue that binds cells together in the body. Deficits in adhesion molecules would be expected to compromise processes at the interfaces between cells, influencing tissue integrity and cell-to-cell signaling. In the brain, deficits in adhesion molecules could compromise brain development and communication ...
University of Granada researchers have developed a cell phone that can be downloaded free from App Store and improves basic competences (maths, language, knowledge of the environment, autonomy and social skills) in children with autism-related disorders or Down Syndrome.
This application--named Picaa--can be used on iPhone, iPad and iPod touch and has been translated into several languages (English, Galician, Arab, etc.). This application has topped the 20,000 downloads from App Store--mainly from Spain and the USA--since its release. Picaa is a system designed for the ...
Black holes are surrounded by many mysteries, but now researchers from the Niels Bohr Institute, among others, have come up with new groundbreaking theories that can explain several of their properties. The research shows that black holes have properties that resemble the dynamics of both solids and liquids. The results are published in the prestigious scientific journal, Physical Review Letters.
Black holes are extremely compact objects in the universe. They are so compact that they generate an incredibly strong gravitational pull and everything that comes near them ...
