Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. Over those 15 years, US global warming emissions declined about 17 percent.

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

All told, they represent 56 percent of the US population, generate 62 percent of the country’s gross domestic product, and are responsible for 43 percent of the country’s annual carbon emissions. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. More than 20,000 Americans died prematurely in 2015 from tailpipe emissions, according to a 2019 study.

Five Reasons “Natural” Gas is Bad for You and the Environment

Enviromental Defense

In Ontario, fossil gas is used primarily for generating electricity, for heating buildings (residential and commercial), and for industrial uses (for heating substances and as a raw material). In fact, Ontario is planning to build new gas plants and extend expiring gas plant contracts to produce electricity. It is none of those things.

Unraveling LA’s Hydrogen Combustion Experiment

Legal Planet

This is partly because hydrogen production is energy inefficient and––when derived from fossil fuels––still a significant source of carbon emissions. Green hydrogen––produced with renewable electricity and water­­––is often described as a tool for decarbonizing the challenging last 10% of greenhouse gas emissions.

Killing King Coal is the First Step Towards Halving Our Emissions

Edouard Stenger

As I have spent some sleepless nights since the latest IPCC report on how Mankind has to halve its carbon emissions by 2030. As we shall see, this is already currently happening, it is the moral thing to do, the best economic choice, and the fastest and easiest way to halve our emissions. Current situation.
