Mercury is a toxic element whose unique properties make it one of the most useful and pervasive substances, and as such, concentrations in places around the world have risen to levels of concern. The Great Lakes is one such place. There have been intensive efforts by many government and international bodies to reduce the use and emission of mercury to the environment.
In this document, there are estimated emissions from power generation in Mexico, based on fuel consumption, as well as emission factors for specific power generation plants, for the years 2001 and 2002.
This paper provides an overview of the status and trends of invasive alien species and their pathways of invasion into the marine and freshwater systems of North America.
This Phase 1 report builds on past studies to summarize the size of Canada’s major biomass resources (forestry, agricultural, and municipal residues, landfill gas and energy crops) and for each sector identifies a number of possibilities and technologies that could be applied to this resource for energy and other potential commercial purposes.
Following are the main agreements and outcomes from the Ensenada trinational workshop held on 23 January 2004, carried out with the goal of developing the framework and identifying the essential elements of an action plan to implement a NAMPAN pilot.
The following account offers the main agreements and outcomes from the Ensenada trinational workshop (January 21-22, 2004) carried-out with the goal of developing the framework and the essential elements of a North American Action Plan (NACAP).
The Eco-S.A.T., NAGPI’s environmental purchasing self-assessment tool, consists of best practices guides Part A and B as well as the corresponding checklists A and B. Part A, “Infrastructure” assesses the degree to which your organization has adequate policies and practices in place. Part B, “Procurement Process”, highlights the environmental considerations faced at each step of […]
Currently 25 US states, as well as the United States federal government and, in Canada, the province of Quebec, which have either passed or proposed legislation requiring (or setting as a goal) a certain proportion of their electricity production to come from environmentally preferable fuel sources. These pieces of legislation are most commonly referred to […]
The need to increase the amount of renewable generation to meet regulatory obligations as well as voluntary purchases of renewable energy by residential and commercial customers has rapidly expanded the marketplace for renewable electricity certificates (RECs). Electronic issuing and tracking systems have been developed in parts of North America, European Union and Australia to support […]
In this project we evaluated the impact of air pollutants on children’s health in Ciudad Juárez, Chihuahua, Mexico, focusing on groups that have different living conditions as estimated by their socio-economic status (SES). We studied two major health outcomes, mortality and morbidity, and their relation to ambient air pollutant levels of particulate matter less than 10 µm and ozone.
Managed forest ecosystems—agroforestry systems in which crops such as coffee and bananas are planted side-by-side with woody perennials—are being touted as a means of safeguarding forests along with the ecological services they provide. Yet we know little about the determinants of land cover in such systems, information needed to design effective forest conservation policies. This paper presents a first-ever spatial regression analysis of land cover in a managed forest ecosystem—a shade coffee region of coastal Mexico.
The Commission for Environmental Cooperation’s (CEC) North American Regional Action Plan on Mercury (NARAP) is intended to assist the governments of Canada, Mexico and the United States in reducing the exposure of North American ecosystems, fish and wildlife and humans to mercury, through the prevention and reduction of anthropogenic releases of mercury to the North […]
