Republican states' lawsuits halted the Obama-era Clean Power Plan. Now Democrats hope to replicate the model.
In August 2015, for the first time, the federal government issued regulations on carbon emissions from power plants. The rules included an interim goal and a final goal for each state of allowable CO2 emissions with the overarching goal of cutting carbon pollution by 32 percent by 2030.
Thirty miles north of New York City, nestled along the scenic banks of the Hudson River, lies the Indian Point nuclear power plant. On January 26, 2016, Tritium-contaminated water leaked into the groundwater beneath the facility.
On March 11, 2011, following a massive earthquake and a devastating tsunami, the cores of three of the reactors at Japan's Fukushima nuclear plant melted down with horrific results. Radioactive cesium, with a half-life of 30 years, contaminated almost 12,000 square miles of the country.
The action came about a month after the high court put on hold federal regulations to curb carbon dioxide emissions mainly from coal-fired power plants.
