We Need an Agreement to Phase out Fossil Fuels at COP28

Union of Concerned Scientists

Emissions of nitrogen oxides (NOx), sulfur dioxide (SO 2 ) and toxics like mercury add further to the health and environmental burden of fossil fuels. These climate, health and justice imperatives are the reason the world needs to phase out fossil fuels and transition to clean energy rapidly. Particulate matter (PM2.5)

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. How is that going to happen? Their report, however, comes with a warning.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

Gas plants and infrastructure emit nitrogen oxides (NOx) during combustion, which degrade local air quality. VY: Clean energy sources will be absolutely pivotal for an equitable and reliable grid. How can we make sure the decisionmaking process for a clean grid transition is equitable? First, there’s air pollution.

A 100% Renewable Energy Future is Possible, and We Need It

Union of Concerned Scientists

A transition to 100 percent renewable energy is about more than just technology. I also find it fascinating to learn about bigger, more powerful wind turbines that better harness wind energy on land and in the ocean. by 2035 is needed. Similarly, communities now tied to fossil fuels need support in moving beyond that dependence.

Fossil Fuels Must Go: Re-inventing US Transportation

Union of Concerned Scientists

Contrary to claims made by some pundits, this transition away from fossil fuels can be done at moderate cost, primarily with technologies that are commercially available today. Electricity is undoubtedly the best choice of fuel in the transition, as it is a proven technology and a efficient way to propel vehicles of all types and sizes.

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

Union of Concerned Scientists

We also evaluated the potential to accelerate the use of renewable energy dramatically through state-level renewable electricity standards, which have been major drivers of clean energy in recent decades. Under the no-new-policy scenario, sulfur dioxide and nitrogen oxides decline only by 27 percent and 18 percent, respectively.

If the US Meets Its Climate Goals, We Can Save Money and Lives

Union of Concerned Scientists

The case for phasing out of fossil fuels and making a just and equitable transition to clean energy has never been more clear. Contrast that with some of the wider benefits of the clean energy transition, such as phasing out coal generation by 2030, which are realized by everyone including historically disenfranchised groups.
