Global Warming Issues & Threats

A small handful of companies are responsible for the majority of the greenhouse gas emissions causing global warming. In fact, just 90 fossil fuel companies account for almost two-thirds of carbon dioxide emissions since the beginning of the Industrial Revolution.

Coal was once king in the U.S., even accounting for more than 40 percent of our electricity. But coal, the most polluting of all fossil fuels, is bad news for our health and the environment. The good news is people around the world are moving away from dirty, polluting coal in favor of clean, renewable, affordable energy.

Right now, we have the chance to quit coal for good and keep remaining U.S. coal reserves in the ground.

Read more about why we need to quit coal once and for all.


The last thing the world needs is more oil. As with other fossil fuels, our reliance on oil is fueling climate change, polluting priceless landscapes and costing billions of dollars. Fossil fuel companies are fighting to maintain the status quo, but we’re fighting back.

We’ve got great opportunities today to build a cleaner energy system in time to avoid the worst impacts of climate change—and oil has no part in it.

Fracking is the fossil fuel industry’s latest false solution to our energy challenge. It’s more expensive, more polluting, and more dangerous than clean, renewable energy. Fracking is diverting money and attention from the real long-term solutions we need for a sustainable energy system, while adding to greenhouse gas pollution and environmental degradation.

So why are we pursuing fracking in the first place?

Nuclear Energy

Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous. And just because nuclear pollution is invisible doesn’t mean it’s clean. Renewable energy is better for the environment, the economy, and doesn’t come with the risk of a nuclear meltdown.
