CSAPR the friendly...rule designed to decrease air pollution that crosses state lines. While not as entertaining as a children’s cartoon, the Cross-State Air Pollution Rule has led to significant emission declines.
This page provides an overview of the cross-state air pollution rule, the states affected and their requirements, and the benefits and costs of the rule
Happy #MountainDay! Check our website to see if there is a Clean Air Status and Trends Network monitor near a mountain you might explore today. Monitors, like the one here at Whiteface Mountain, NY, observe levels of ambient air pollution in the area. https://www.epa.gov/castnet/castnet-site-locations
We’ve seen improvements in emissions of sulfur dioxide, nitrogen oxides, and carbon dioxide since 1995. Interactive 📉graphs📊and maps🗺️on our Power Plant Emissions Trends page illustrate these changes.
This page details power plant emission trends from coal-fired power plants over time, comparing those emissions with electricity generation. Maps illustrate the locations where the facilities with the highest emissions.
Using data from our Emissions & Generation Resource Integrated Database (eGRID), we’ve created a tool that shows you the type and amount of emissions produced in your region. How clean is the electricity you use? https://www.epa.gov/energy/power-profiler#/
You know the Acid Rain Program is celebrating its 30th birthday this year, but #DYK its legacy continues with emissions trading programs that further reduce power plant emissions? More details are just a click away.
Learn more about Clear Air Markets Programs, including current programs, retired programs, related EPA programs, EPA tools and resources, and international efforts.

We are thrilled to begin working with the outstanding winning teams for the 2nd EmPOWER Air Data Challenge:
1.) Hourly Average Emissions Factors for eGRID: led by @ucdavisenergy, the team will create a database of hourly average eGRID emissions factors and analyze how hourly emissions factors impact GHG inventory calculations.
2.) An accessible education tool presenting 20 years of monthly source impacts: led by @GMU_CEIE, the team will use emissions and CASTNET data to assess and visualize the health benefits of control installations and shutdowns at coal-fired power plants.
CAMD is looking for researchers and students to more practically use the wealth of power sector data knowledge that CAMD has. For those that use CAMD's data, they will discuss conclusions or questions with CAMD staff to better understand and analyze data.
