Tier 3: What It Means and Why It Matters

By Mark MacLeod / Published: April 4, 2013

By now, you’ve probably seen lots of news headlines talking about the proposed updated Tier 3 standards.

Tier 3 is the shorthand term for national vehicle emissions and fuel standards that will help us make big strides towards cleaner, healthier air. They are designed to reduce the soot, smog and other types of dangerous pollution that come from the tailpipes of our cars and trucks.

The U.S. Environmental Protection Agency (EPA) just announced the proposed standards to enthusiastic responses from everyone from health advocates to automakers (including EDF, of course).

What exactly are the Tier 3 standards, and why are they so important? Here are answers to some common questions:

What’s the story behind the Tier 3 standards?

Cars and trucks are one of the biggest sources of air pollution in America. For years, EPA has been looking for ways to reduce the pollution associated with those motor vehicles.

In 2000, they created standards that would attack the air pollution problem at two of its sources at the same time – by reducing impurities in gasoline, so what you put into your car is cleaner, and by improving cars’ emission systems, so what comes out of your car is cleaner.

They called these standards Tier 2.

Now, EPA is proposing to update the standards. The new, improved version – called Tier 3 – will keep the proven approach of treating vehicles and fuels as an integrated system.

Starting in 2017, the new proposal would strengthen the earlier standards in order to reduce the pollutants from both gasoline and auto emissions standards in the most cost-efficient ways possible.

The proposed Tier 3 standards are also designed to work in harmony with America’ new clean car standards, which will improve fleet-wide fuel efficiency in new cars to 54.5 miles per gallon by the year 2025, and with California’s state standards, which are already stricter than the national average.

How exactly would the Tier 3 standards work? 

Cars and light trucks are the second largest emitters of oxides of nitrogen and volatile organic compounds in the U.S. Those are the primary pollutants that form ozone.

According to EPA, the proposed Tier 3 standards would slash the level of those pollutants by 80 percent.

The proposed Tier 3 standards would also establish a 70 percent tighter particulate matter standard. Particulate matter, more commonly known as soot, is one of the most dangerous types of air pollution. It has been linked to asthma attacks, bronchitis, heart attacks and other types of heart and lung diseases.

The proposed Tier 3 standards would reduce other noxious types of air pollution as well, including carbon monoxide, benzene and butadiene. They would reduce fuel vapor emissions to near zero.

At the same time, the proposed Tier 3 standards would reduce the amount of sulfur in gasoline by more than 60 percent, to no more than 10 parts per million of sulfur on an annual average basis by 2017.

Lower sulfur levels in gasoline will allow vehicles to run more efficiently.

It also means we’ll see immediate benefits once the proposed standards go into effect in the year 2017. That’s because older cars that are already on our roads will emit less tailpipe pollution –right away — thanks to the cleaner gasoline. (The cleaner emissions systems will be built into new cars, and we’ll see those additional benefits emerge more gradually as Americans buy those cars to replace their old ones).

What are the benefits of Tier 3?

Tier 3 would be good for public health and for the economy

By the year 2030, EPA estimates that Tier 3 would:

  • Prevent up to 2,400 premature deaths every year
  • Prevent 3,200 hospital admissions and asthma-related emergency room visits every year
  • Prevent tens of thousands of cases of respiratory illnesses in children every year

EPA also estimates that by 2030, Tier 3 would prevent 1.8 million lost school or work days each year, and would provide total health-related benefits worth up to $23 billion per year.

How much will Tier 3 cost?

We can reduce tailpipe pollution and provide healthier, longer lives for millions of Americans for less than a penny per gallon of gas.

How will America’s gasoline standard compare to other countries?

The proposed Tier 3 standards for sulfur levels in gasoline are similar to levels that are already required – and being achieved – in Europe, Japan, South Korea, and several other countries (as well as California, here in the U.S.).

Do businesses support Tier 3?

Many businesses do support updating the standards, including automakers and the emissions control industry.

Tier 3 would provide greater regulatory certainty for automakers; a national standard means the auto industry can build a car that can be sold anywhere in the country.

On the day the proposed standards were announced, Michael Stanton, president and CEO of the Association of Global Automakers said:

We have been anxiously awaiting this rulemaking because it is good for the environment and will help harmonize the federal and California programs for both vehicles and fuel …  With 15 million new vehicle sales a year, automakers need predictable national fuel quality at the retail pump. Ultra-low sulfur gasoline is already available in California, Europe, and Japan and will enable automakers to use a broader range of technologies to meet the significant environmental challenges facing the industry.

Gloria Bergquist, Spokeswoman for Alliance of Automobile Manufacturers said:

This is a big step forward for this country to catch up to the clean fuels available in other industrialized nations. Automakers have already reduced vehicle emissions by 99 percent, and we’re working to go further while also delivering high quality, affordable vehicles to our customers.

And the United Auto Workers said:

This is one of the most cost-effective ways for us to get cleaner and healthier air while strengthening our domestic auto sector and creating thousands of new jobs … The proposed rule is a win for our economy and a win for public health.

Who else supports Tier 3?

Even before EPA unveiled its proposal, state and local officials, national recreation groups, health groups and the public – as well as the automakers and the emissions control industry — all announced their support for updating the standards.

EPA has compiled a list of what all those supporters are saying. It’s a very long list. You can read it here.

What happens next?

EPA will hold two public hearings about the proposed Tier 3 standards, the first on April 24th in Philadelphia and the second on April 29th in Chicago.

EDF will be sending experts to testify at both those hearings, and we’ll report back from them. EPA will also begin accepting public comments soon.

Executive Action Critical, but not Enough to Fight Global Warming

By Keith Gaby / Published: March 29, 2013

(This blog was first posted on EDF Voices)

I received the following comment about Part 1 of this series that warrants its own blog post.

The politics of climate change is an issue The Nation has covered extensively, and I think many of our readers would wonder why Mr. Gaby, in asserting that Congressional legislation is the only means of taking serious federal action against climate change, ignores the argument (put forth by the Center for Biological Diversity, among others) that President Obama and his EPA Administrator already have the authority under the Clean Air Act to order dramatic reductions in U.S. greenhouse gas emissions.

Congress is one way; it is hardly the only way. And since Congress is now blocked by right-wing intransigence, and since the hour (as Mr. Gaby notes) is already very late, surely it behooves us to deploy a readier tool, no?  —  Mark Hertsgaard, environment correspondent for The Nation magazine and  author of numerous books about climate change, including HOT:  Living Through the Next Fifty Years on Earth. Mr. Hertsgaard is also a Fellow of the New America Foundation.

My response:

Because Congress failed to pass comprehensive climate legislation in 2010, and prospects for action in the current Congress are remote, many environmentalists have been focused on steps President Obama can take on his own. And it is true that the President has authority under the Clean Air Act to take significant action to limit greenhouse gas emissions. But while these steps are both necessary and critically important, they do not let Congress off the hook in the long run.

Why? To borrow a line from the 2012 campaign, it’s simple math.

The World Resources Institute recently studied the impact of actions the EPA could take under existing law. In Goldilocks style, they laid out three scenarios – lackluster, middle-of-the-road, and go-getter – based on the aggressiveness of EPA’s approach. Unlike the home-invading blonde of the fairy tale, WRI recommends the most aggressive approach, which would reduce emissions 17% below 2005 levels by 2020. That’s the same level of reductions that would have been achieved by the failed congressional legislation. What’s more, this path would result in a 40% reduction in pollution by 2050.

So what’s the problem?  Well, a 40% reduction is only half of what we need to achieve to avert the worst impacts. In other words, we can’t get to a safe climate from here without action by Congress, even under the most aggressive scenario of executive action. As WRI says, “New federal legislation will eventually be needed, because even go-getter action by federal and state governments will probably fail to achieve the more than 80 percent GHG emissions reductions necessary to fend off the most deleterious impacts of climate change.”

Without that level of commitment, we also won’t see other countries achieve the reductions necessary. While about one-third of the world’s economic output is technically covered by some form of greenhouse gas emissions limit, these rules are far from enough to solve the problem. And while growth-hungry nations in Asia are starting to take steps on climate change, they will likely insist on bold action by the United States before moving as aggressively as is necessary.

The most important short term domestic priority for environmentalists should be ensuring that EPA carries out its obligations under the Clean Air Act*. That would cut billions of tons of pollution and buy us critical time in the fight against climate change. But if we are to prevent the worst impacts of artificially altering the Earth’s natural systems, we need Congress to eventually accept its responsibility to protect the nation.

If You Can’t Stand the Heat: Why Washington is Stuck on Climate Change (Part 1)

By Keith Gaby / Published: March 21, 2013

(This blog was first posted today on EDF Voices)

There is no point in being coy about this: The issue of climate change is polarized along partisan and ideological lines.

Democrats and progressives think it is a dangerous threat to the world. Most Republicans and conservatives think the threat is exaggerated, or doesn’t exist at all. The divide among politicians is even more striking – less than a third of Republicans in Congress responding to a 2011 National Journal survey said climate change is causing the Earth to warm.

 

 

 

 

 

 

 

 

 

 

Against this political backdrop, many critics say that groups like EDF, which  seek to start a dialogue with conservatives on the issue, are  naive.  No conciliatory language, no middle-ground proposals, they say, will draw more than a few Republican votes in Congress. Conservative members of Congress will simply vote against us once Rush Limbaugh starts railing against the global warming “hoax”.

It’s a reasonable argument, but I think it misses an essential point: It may be hard to pass climate change legislation by working with conservatives, but it will be nearly impossible to do so without them. In fact, no major environmental law has ever been passed without large bi-partisan majorities.  The Clean Air Act, the Clean Water Act, the National Environmental Policy Act, the 1990 Clean Air Act Amendments all passed with lots of votes from both major parties.

No important legislation can become law without sixty votes in the Senate.  And I think you will search in vain for a respected political analyst who thinks there will be sixty progressive, pro-environment senators any time soon.  On an issue that doesn’t allow for the long game – as the atmosphere loads with greenhouse gases and the ice caps melt – we can’t wait decades for that super-majority to appear.

That leaves us two choices: act without Congress, or open a conversation with conservatives and move towards an approach that can get widespread support.  President Obama has already used his executive powers to limit greenhouses gases, including a clean cars rule and proposed standards for new power plants. We hope he will soon add pollution limits for existing power plants and policies to limit methane leakage from natural gas production.

All of that, along with actions by states like California’s AB 32, will be an important down payment on what we need to do. But in the long run it won’t be nearly enough to prevent the worst impacts of climate change.  Nothing short of a comprehensive solution to shift America to cleaner energy, and lead the world that way, will suffice.  And that means Congressional action.

Next: Why do many conservatives reject the consensus of scientists on climate change?

Sequestration – What It Means For You, What It Means for Planet Earth

By Keith Gaby / Published: March 7, 2013

Now that the automatic spending cuts known as “sequestration” are here, we’re getting a clearer look at what it will mean for our environment. In these economic times, budget cuts are a fact of life. But these non-targeted, across-the-board cuts are likely to have real consequences for our environment:

  • The Environmental Protection Agency (EPA) will have to cut the funding it gives states to monitor their air quality.
  • EPA says it will likely have to shut down some critical air monitoring sites that check for dangerous pollutants like ozone and particulate matter.
  • EPA also says it will have to reduce the number of “environmental cops on the beat” – the people who monitor compliance with our environmental laws. They estimate they’ll do 1,000 fewer inspections this year. That means more polluters will get away with putting our health at risk.
  • Funding that was given to communities to repair or replace decaying water and wastewater infrastructure will be cut. That puts your local safe drinking water at risk.
  • The Federal Emergency Management Agency (FEMA) will have to cut grants for state and local firefighters and other emergency management personnel. That will make it harder to respond to the next hurricane, tornado, or other weather disaster – at a time when those weather disasters are intensifying because of climate change.
  • The Agriculture Department says it will treat as many as 200,000 fewer acres for hazardous fuel because of budget cuts. That means a higher risk of wildfires.
  • The National Oceanic and Atmospheric Administration (NOAA) will delay the launch of two new satellites that are designed to track severe weather events like hurricanes and tornadoes.
  • NOAA will also cut back on maintenance and operations of some its other weather systems — including the national radar system that’s used for tornado warnings. The Secretary of Commerce, who oversees NOAA, warned that sequestration will: 

significantly increas[e] forecast error and, the government’s ability to warn Americans across the country about high impact weather events, such as hurricanes and tornadoes, will be compromised.

  • NOAA will also have to reduce the surveying that goes into nautical charts, which would put navigation – and the millions of dollars of commerce that depends on it – at risk.
  • Sequestration may force national parks across the country to close, or to operate with shorter hours. Reports say Yellowstone may open three weeks late to save money on snow plowing.
  • Interior Secretary Ken Salazar says the reopening of the Statue of Liberty after Hurricane Sandy will likely be delayed.
  • Salazar and the head of the Park Service, Jonathan Jarvis, say sequestration will cut into their ability to staff national parks, fight fires, and clean up after winter storms.
  • Sequestration will force reductions in funding for fishery stock assessments, which will jeopardize our ability to open economically vital fisheries from the Gulf Coast to Alaska.
  • Sequestration also means fewer people to enforce laws against overfishing. The Commerce Department says they may have to compensate with smaller quotas or early closure to the fishing season.

All of the above examples are from memos written by agency heads to Congressional leaders about the potential effects of sequestration. There will undoubtedly be other effects – and we don’t know what they’ll be.

Of course, today’s budget issues pale in comparison to the financial disasters that loom ahead of us  – the amount we’ll have to spend to recover from stronger storms, droughts, and other extreme weather as climate change accelerates.

We’re leaving our kids a huge bill to pay.

New Reports about Weather Disasters, Cost, and Climate Change

By Steven Hamburg / Published: January 29, 2013

Congress just passed a bill to provide more than $50 billion to victims of Hurricane Sandy.

If you think that seems like a lot of money, consider this – Hurricane Sandy was just one of the eleven weather disasters in the U.S. last year that caused more than $1 billion each in losses.

For a long time now, the world’s top climate researchers have told us about the strong evidence of links between our weird weather and climate change.

(Of course, here at EDF, we’ve been talking about the links between weird weather and climate change too — as regular readers of Climate 411 know.)

Greenhouse gas pollution traps heat in our atmosphere, which interferes with historic weather patterns – and is resulting in more severe and damaging weather events.

Our particularly awful weather last year has put climate change back in the news:

  • In his Inaugural Address, President Obama talked about the threat of climate change — saying, “Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires and crippling drought and more powerful storms.”
  • Two Members of Congress just formed a new bicameral task force on climate change.
  • The World Economic Forum just released its Global Risks Report 2013, which says: “Following a year scarred by extreme weather, from Hurricane Sandy to flooding in China, respondents rated rising greenhouse gas emissions as the third most likely global risk overall.”

How bad was it really? Four other reports — all released in the last few weeks – found that evidence showing the impacts of climate change is piling up.

Two new reports from the National Oceanic and Atmospheric Administration (NOAA) show that both America and the world are warming – by leaps and bounds.

According to NOAA, “By a wide margin, 2012 was the United States’ warmest year on record.”

NOAA’s State of the Climate National Assessment found that the average temperature for the continental U.S. in 2012 was one full degree Fahrenheit higher than the previous warmest year on record – and 3.2 degrees Fahrenheit above the 20th-century average.

And NOAA’s State of the Climate Global Analysis found that 2012 was the 36th consecutive year with a global temperature above the 20th century average. That means the last time the global temperature wasn’t above average was in 1976 – when America was celebrating its bicentennial and Jimmy Carter was elected President. Anyone under the age of 35 has never seen a year when the Earth wasn’t hotter than the 20th century average.

NASA also measures global temperatures, and their report also found 2012 to be one of the top 10 hottest years ever for planet Earth.

Why? According to NASA scientist Gavin Schmidt,

The planet is warming. The reason it’s warming is because we are pumping increasing amounts of carbon dioxide into the atmosphere.

Let’s go back to NOAA’s data for more frightening statistics from 2012:

  • Every state in the contiguous United States had an above-20th century-average annual temperature. (You can check NOAA’s web page to see which cities broke any records or had their hottest year).
  • July 2012 was the hottest month ever observed in the continental U.S. since we began keeping records in 1880.
  • Nineteen states had their warmest year on record, and another 26 states had one of their ten warmest years since 1880.
  • Temperatures were above the 20th-century average in every month from June 2011 to September 2012 – an unbroken 16-month stretch that we’ve never seen before since we started keeping records.
  • The winter snow cover for the contiguous United States was the third smallest on record, and snowpack totals across the Central and Southern Rockies as of April 2012 were less than half of the 1971-2000 average.

In 2012, America also had the second largest extent of extreme weather events ever recorded in a single year. (A weather event has a variable at the high or low end of the observed historical range.)

And we saw vastly different types of weather extremes at the same time – which is consistent with weird weather linked to climate change. While most of the continental U.S. withered in drought, some areas got drenched — Florida had its wettest summer on record.

Along with Hurricane Sandy, 2012 weather lowlights include:

  • Hurricane Isaac, which caused flooding along the Gulf Coast and killed 9 people.
  • The Derecho storm that caused severe damage in eleven states from Indiana to Maryland.
  • Flooding in and around Duluth, Minnesota, where rivers reached all-time high flood levels.
  • A massive drought that covered more than 60 percent of the country and led to widespread crop failures. Crop prices are now rising because of last year’s drought. Corn, wheat and soybean prices are all up – which means your grocery bills will soon be up too.
  • Wildfires burned more than nine million acres around the West, about 1.5 times the ten year average from 2001 to 2010. A fire near Colorado Springs destroyed almost 350 homes, and New Mexico recorded its largest wildfire ever. Wildfire risk increases when drought is combined with high heat and low levels of humidity.

Now for the really bad news – it’s likely to get worse.

This month, the U.S. government released a first draft of another new report, the National Climate Assessment. More than 300 scientists contributed to writing the report, which warns that the U.S. could warm up to 10 degrees Fahrenheit by the end of the century, unless we take steps now to reduce climate change.

According to the assessment:

Evidence for climate change abounds, from the top of the atmosphere to the depths of the oceans … The sum total of this evidence tells an unambiguous story: The planet is warming.

Unfortunately, the new reports are just the tip of the rapidly-melting iceberg. There’s a lot more evidence of climate change and its effects on our weather — evidence that shows that we need to take serious action to reduce carbon pollution and stop climate change.

Automakers Defend Historic Clean Cars Standards

By Graham McCahan / Published: January 15, 2013

The world’s biggest automakers are standing up in court to defend America’s historic new fuel economy and greenhouse gas emissions standards.

The Obama Administration announced the clean cars standards last August.

The new standards will double fleet-wide fuel economy by 2025, to 54.5 miles per gallon.

They’ll also:

  • Save families more than $8,000 at the gas pump over the lives of their new cars or trucks
  • Dramatically reduce our nation’s dependence on oil
  • Cut greenhouse gases by six billion tons

By 2025, the standards are projected to reduce U.S. oil consumption by more than two million barrels per day.  Combined with earlier standards for large diesel trucks, the daily oil savings in 2025 will be substantially more than the amount of oil imported each day from Iraq, Kuwait, and Saudi Arabia in 2011.

The six billion tons of greenhouse gas reductions are more than the total of U.S. carbon dioxide emissions in 2010.

(You can read more about the standards, and their benefits on our website)

These historic standards are supported by consumers, the United Auto Workers, national security experts, U.S. automakers, many U.S. states, the Union of Concerned Scientists, and environmental organizations.

Unfortunately, there are some groups that don’t support them.

Industry groups — including the Utility Air Regulatory Group, American Petroleum Institute, National Association of Manufacturers, and National Oilseed Processors Association — have filed legal challenges in the U.S. Court of Appeals for the District of Columbia.

EDF will defend these historic standards in court. We and our allies have already moved to intervene in support of them.

Now, both U.S. and foreign automakers have also stepped in to defend the landmark standards.

Yesterday, the Alliance of Automobile Manufacturers filed a motion to intervene in support of the standards.

Their motion says that the court challenges:

jeopardize the further development and continuation of an integrated national approach to increasing automobile fuel economy and thus reducing carbon emissions.

Just three days earlier, the Association of Global Automakers also filed a motion to intervene in support of the standards.

Members of the two automaker groups include Chrysler, Ford, General Motors, Honda, Toyota, Volkswagen, and Volvo.

It’s a great reminder that when we work together, America can achieve lasting gains for our environment and our economy.
