EPA's Affordable Clean Energy rule (ACE), would restore the states' proper role under the Clean Air Act and our system of federalism. Our plan would allow states to establish standards of performance that meet EPA emissions guidelines.

I have considered the subject of missions nearly a year and have found my mind gradually tending to a deep conviction that it is my duty personally to engage in this service.

Adoniram Judson

The struggle against poverty in the world and the challenge of cutting wealthy country emissions all has a single, very simple solution... Here it is: Put a price on carbon.

Al Gore

I always knew that I wanted to work on my own material - something that would be more long-lasting than short-lived electronic transmissions.

Alan Bradley

When we first sent missions to Jupiter, no one expected to find moons that would have active volcanoes. And I could go down a long list of how often I've been surprised by the richness of nature.

Alan Stern

During one of the Apollo missions, I saw Walter Cronkite showing off the flight plan. It just mesmerized me. All this detail! That's what I wanted.

Alan Stern

As a scientist in charge of space sensors and entire space missions before I was at NASA, I myself was involved in projects that overran. But that's no excuse for remaining silent about this growing problem or failing to champion reform.

Alan Stern

I've been on 26 space missions; they range from suborbital to orbital to shuttle experiments to planetary missions.

By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.

Alex Steffen

There's a lot of evidence that shows that if we push as hard as we need to for net-zero emissions, we'll find ourselves with cities that are more secure, healthier, and have more economic opportunity - are frankly better cities to live in - than if we settle for the status quo.

Alex Steffen

Carbon zero simply means that the emissions you are releasing either are zero or balance out to zero.

Alex Steffen

Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future.

Maybe libertarians especially like Reddit because it is a perfect marketplace of content. Every Redditor is created equal, whether you're the highest karma Redditor or a brand-new Redditor with 10 karma points. No submissions or votes are more equal than others.

Alexis Ohanian

Achieving net zero carbon emissions by 2050, identifying treatments to diseases like cancer, and harnessing the power of robotics and artificial intelligence to support everyday tasks are all within our grasp. The first country that gives birth to these discoveries will change life as we know it.

Alok Sharma

Humanitarian missions are little different from any other public enterprise, diplomacy included, which is susceptible of misinterpretation by the public, hence ultimately of failure.

Alvin Adams

I've been doing everything people like to see: knock people out, and submissions, and go in there to fight.

Amanda Nunes

Working together, we can meet our shared goal to combat climate change. From harmonizing vehicle emissions standards to using our trading relationship to boost investment in clean energy, the actions the United States and Canada take together will help both nations meet international goals.

Amy Klobuchar

The government believes that we will need to take the step of enshrining the Paris goal for net zero emissions in U.K. law. The question is not whether but how we do it.

Andrea Leadsom

Safe care saves lives and saves money. Adverse events like high levels of infection, blood clots or falls in hospital, emergency readmissions and pressure sores cost the NHS billions of pounds every year. There is a serious human cost, too, with patients ending up injured, or even dead. Most are avoidable with the right care.

Andrew Lansley

EPA's Affordable Clean Energy rule (ACE), would restore the states' proper role under the Clean Air Act and our system of federalism. Our plan would allow states to establish standards of performance that meet EPA emissions guidelines.

Andrew R. Wheeler

Let's make sure that when companies make investments to reduce emissions that they're rewarded for that and encouraged to do more.
