Waste-To-Energy Tech Could Slash U.S. Water Sector Carbon Emissions, But Its Potential Remains Underdeveloped

Circle of Blue

utilities have been slower to adopt the energy- and emissions-saving technologies than those in other parts of the world. Wastewater-to-energy systems start with a process called anaerobic digestion, which treatment plants have been using for ages to reduce the volume of sewage waste. But it can significantly reduce net emissions.

30 Major Climate Initiatives Under Biden

Legal Planet

Biden sets target of at least 50% reduction in carbon emissions below 2005 levels by 2030. Biden and the EPA select the recipients for $20 billion in grant awards under two competitions within the $27 billion Greenhouse Gas Reduction Fund created under the IRA. EPA’s greenhouse gas emission standards will avoid 1.38

U.S. Pushes Farmers to Develop A New Crop: Energy

Circle of Blue

The law provides $140 billion in tax incentives, direct loans, and grants to replace fossil fuels with cleaner renewable energy that lowers emissions of carbon dioxide. Gevo asserts its “farm-to-flight” project will release 80 percent less carbon dioxide to the atmosphere than ethanol produced by a conventional plant.

Biomethane Threatens to Upend the Clean Hydrogen Tax Credit

Union of Concerned Scientists

The Inflation Reduction Act’s new hydrogen production tax credit , known as code 45V, is intended to incentivize a shift to low-carbon hydrogen production by offering producers a credit that increases in value as the carbon emissions associated with produced hydrogen declines.

Environmentalism and the Supreme Court

Legal Planet

The Court then held that greenhouse gases are covered by the Clean Air Act as a type of air pollutant. This gave EPA the power to impose limits on carbon emissions by vehicles and industry. Solid Waste Agency of Northern Cook County (SWANC) v. Illinois Central Railroad v. Army Corps of Engineers.

Meddling to mend the planet: techno-fixes to environmental problems

Physics World

In theory this could seed clouds that reflect sunlight back into space – counteracting the greenhouse effect. Kolbert runs through the smorgasbord of negative-emissions technologies designed to sequester carbon dioxide. The tomatoes were “perfect, in that greenhouse tomato-y way,” reports Kolbert.
