This EPA report is based on the 2023 Post-fire Research and Monitoring Symposium that was organized by the Oregon Governor’s Post-fire Science Team and was held February 7-9, 2023 at Oregon State University. The Symposium aimed to increase awareness among those conducting post-fi...

Flooded lands are defined as water bodies where human activities have 1) caused changes in the amount of surface area covered by water, typically through water level regulation (e.g., constructing a dam), 2) waterbodies where human activities have changed the hydrology of existin...

Estuaries and coastal areas are highly vulnerable to the impacts of acidification on shellfish, coral reefs, fisheries and the commercial and recreational industries that they support. Yet, little is known about the extent of this vulnerability and the estuary-specific drivers th...

EPA/ORD developed City-based Optimization Model for Energy Technologies (COMET) which is designed to examine energy consumption and management scenarios under various environmental policy scenarios implemented at city- and state-level. Initial application of the COMET is piloted ...

The Global Change Assessment Model (GCAM) is an integrated assessment model that links the world's energy, agriculture and land use systems with a climate model. The model is designed to assess various climate change policies and technology strategies for the globe over long tim...

This report uses results from a previous report titled <em>Assessment of the Impacts of Global Change on Regional U.S. Air Quality: A Synthesis of Climate Change Impacts on Ground-Level Ozone</em>, a number of high-resolution, spatially explicit population projections developed ...

This report was prepared by the Global Change Research Program (GCRP) in the National Center for Environmental Assessment (NCEA) of the Office of Research and Development (ORD) at the U.S. Environmental Protection Agency (EPA). This draft report is a review of decision-making pro...

Anaerobic digestion is a natural biological process in which microorganisms break down organic materials in the absence of oxygen. When anaerobic microbes metabolize organic waste – i.e., the carbon-based remains of plants, animals and their waste products, e.g. animal manure, se...

EPA announced the availability of the final report, <em>The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields</em>. This report assesses the state of the science on the environmental impacts of mountaintop mines and valley ...

EPA announced the availability of the final report, <em>An Assessment of Decision-Making Processes: Evaluation of Where Land Protection Planning Can Incorporate Climate Change Information</em>. This report is a review of decision-making processes of selected land protection prog...

EPA has released this draft document solely for the purpose of pre-dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy ...

The evolution of the energy system in the United States is an important factor in future environmental outcomes including air quality and climate change. Given this, decision makers need to understand how a changing energy landscape will impact future air quality and contribute ...

Flooding is a major natural hazard which every year impacts different regions across the world. Between 2000 and 2008, various types of natural hazards, mainly floods have affected the largest number of people worldwide, averaging 99 million people per year (WDR, 2010). In the U...

EPA’s Ecosystem Services Research Program in the Office of Research and Development is focused on the study of ecosystem services and the benefits to human well-being provided by ecological systems. As part of this research effort, the Willamette Ecosystems Services Project (WE...

The report gives results of an analysis of three alternative uses of forests in the U.S. to reduce atmospheric carbon dioxide (CO2)concentrations: (1) planting trees with no harvesting, (2) traditional forestry, and (3) short-rotation intensive culture of trees for biomass. ncrea...

The report describes an alternative mitigation process that would convert waste carbon dioxide (CO2) to carbon an methanol using natural gas as process feedstock. The process yields 1 mole of methanol from each mole of CO2 recovered, resulting in a net zero CO2 emission when the ...

The report documents the 1995 Symposium on Greenhouse Gas Emissions and Mitigation Research, sponsored by the U.S. Environmental Protection Agency's Air Pollution Prevention and Control Division (EPA/APPCD), in Washington, DC on June 27-29, 1995. The symposium provided a forum of...

This report describes the FASOM-GHG model (Forestry and Agriculture Sector Optimization Model with Greenhouse Gases), the GHG mitigation scenarios for U.S. forestry and agriculture run through the FASOM-GHG model, and the results and insights that are generated. GHG mitigation po...
