Southeast Green - Business depends on the environment and the environment depends on business


Time for the Southeast to Act on Climate this Earth Day

Heather McTeer-ToneyThe Southeast will join the rest of the nation and countries across the world in celebrating Earth Day on April 22. The entire month of April is a great time to reflect on the strides we have made to reduce pollution over the last 44 years, and assess current environmental conditions while evaluating our personal responsibility to a cleaner environment.

This year’s theme, “Act on Climate,” serves to remind us that we—individually and collectively—have the power to reverse the damaging effects of climate change. Climate change is a serious threat to the health and welfare of American families—particularly in the Southeast, which has experienced more billion dollar weather and climate-related disasters than any other region.


Green Microfinance Lifting Entrepreneurs out of Environmental Degradation

Green microfinance can be defined as a financial sector which is trying to improve present environmental conditions. It can be done by creating special incentive for underserved categories. Green microfinance will provide economically challenged people to use various other sustainable practices and can focus on environmentally friendly zones. It can also be defined as an effective means to build the green economy. There are various avenues that will make more links between environmental stewardship and economic growth.


A tax proposal that conservatives and environmentalists alike could learn to love


Swap a carbon tax for the payroll tax and eventually pave the way for the “Fair Tax”

Tax Swap – A Way to Expand the Economy While Lowering Carbon Emissions

What do such problems as global warming, air pollution, toxic waste, traffic congestion, unemployment, loss of jobs overseas, overuse of non local food sources, underground economy, lack of competitiveness of American workers, excessive small business paperwork and a complicated tax system have in common? The answer is that all of these problems can be addressed with a common solution: a tax swap that replaces payroll taxes with a tax on carbon dioxide emissions. This tax swap is a dual pronged solution to a seemingly intractable set of problems facing our nation today.


Dirty for decades, diesel tractors, bulldozers get cleaned up

Dark clouds of soot and gases spewed by tractors, bulldozers and backhoes are becoming a thing of the past under new federal standards that have forced cleaner diesel engines this year

Environmental Health News - Backhoe Pollution

Dark clouds of soot and gases spewed by tractors, bulldozers and backhoes are becoming a thing of the past under new federal standards that have forced cleaner diesel engines this year.

While trucks and buses have been cleaned up, it’s taken years longer for farm and construction equipment to keep pace.

New tractors won't emit black soot under EPA standards.

That’s because these diesel-powered vehicles come in many shapes and sizes, all with different workload demands, and there aren’t always convenient places to slap a filter on their engines.

A variety of new technologies are producing cleaner farm and construction machines. Included are lower-sulfur diesel fuel, particle-trapping filters and more efficient engines with fuel-injection software, recirculated exhaust systems or catalysts that prevent pollutants from forming.

“It’s been a real challenge getting to this point,” said Allen Schaeffer, executive director of the Diesel Technology Forum, which represents engine manufacturers. “But all of this work has virtually eliminated nitrogen oxide and particulate matter from diesel engines.”

The new technologies were prompted by the latest U.S. Environmental Protection Agency emission standards, which took hold this year for new, non-road diesel engines used at farms, construction sites and utilities.

“It’s been a real challenge getting to this point. But all of this work has virtually eliminated nitrogen oxide and particulate matter from diesel engines.”  Allen Schaeffer, Diesel Technology Forum   Under these Tier 4 standards, fine particles – which are linked to heart attacks and respiratory disease – and nitrogen oxides – which contribute to smog – were reduced 90 percent in 2014 models compared with 1996 engines.

Manufacturers, however, have gone above and beyond the standards, cutting the two pollutants by 99 percent, Schaeffer said. Carbon dioxide, a greenhouse gas linked to climate change, also has been reduced through improved fuel efficiency. {Editor's Note: Original story said filters also reduce CO2. They do not. 3/21/2014}

Nevertheless, the new tractors, excavators and other non-road diesels remain dirtier than trucks and buses. They are allowed to emit about 50 percent more grams of particles and nitrogen oxides per kilowatt-hour.

Heavy-duty trucks, since they all have the same basic design, have used similar technologies to cut pollution for seven years. But Schaeffer said “one size doesn’t fit all” for farm and construction equipment.

The foundation for lower emissions is ultra-low sulfur diesel fuel. In 2010 the allowable level of sulfur in diesel fuel dropped to 15 parts per million from 2007’s 500 parts per million. [Editor's Note: Years corrected 3/21/2014]

Engine manufacturers also are targeting emissions at the engine level or through filters that trap pollutants.

There are “almost infinite varieties of installation,” said Scott Woodruff, director of industrial sales for MTU America, a global manufacturer of off-highway diesel engines that is part of Rolls-Royce Power Systems.

Caterpillar Inc., one of the world’s largest manufacturers of non-road diesel engines, started modifying its mid-size engines about a decade ago in preparation for the new standards, said Matthew Delzell, its marketing and sales support supervisor.

The company tackled nitrogen oxides at the combustion stage – by recycling and recirculating exhaust – and targeted particulate matter after combustion, largely with filters, Delzell said.

MTU America wanted to limit its reliance on catching pollutants at the exhaust stage, Woodruff said. Instead, they have largely used cylinder combustion control, which controls the timing and geometry of engines to prevent pollutants from forming in the first place. They also added selective catalytic reduction, which uses a catalyst to trigger a chemical reaction that converts nitrogen oxides into non-harmful elements.

The company’s largest investment has been limiting combustion itself, largely through improved engine software and fuel injection, Woodruff said.

The fixes haven’t been cheap. Both MTU and Caterpillar said the research and development costs were substantial, although they declined to reveal their costs. {Editor's Note: An original version of this story said the companies received federal subsidies; they did not. The funding went to diesel owners. 3/21/2014.]

The EPA estimated in 2004 that the new technologies would cost $1.7 billion and add 1 to 3 percent to each machine’s total cost. That amounts to as much as $3,000 for a tractor that cost $100,000. Construction and farm equipment can range from tens of thousands of dollars each to several hundred thousand dollars.

Woodruff, however, said that the latest standards have added much higher costs than the EPA originally estimated – between 30 and 60 percent per engine.

Farmers are “a little concerned” about the diesel regulations because equipment costs are rising, said Andrew Walmsley, director of congressional relations at the American Farm Bureau.

The federal regulations do not include incentives for farmers to buy new, cleaner equipment.

“We’re pretty good at keeping the older equipment together with duct tape and wire,” Walmsley said, adding that it’s not uncommon to still see tractors and combines from the 1950s and 1960s.

The standards are designed to protect public health, as well as the health of farmers and construction workers. Diesel exhaust is a carcinogen, and PM2.5 is linked to deaths from respiratory disease and heart attacks. Construction workers, truck drivers and railroad workers are more at risk of diesel-related illnesses. In addition, nitrogen oxides help form ozone, the main ingredient of smog.

The EPA estimated that by 2030, the new standards will prevent 12,000 premature deaths and 8,900 hospitalizations per year.

Emissions from the farm and construction equipment already have declined substantially. Volumes of nitrogen oxides and PM2.5 from non-road diesels already are down 25 to 31 percent compared with a decade ago.

The American Lung Association is “very pleased” with the improvements that diesel manufacturers have made, but concerns remain about the old engines, said Janice Nolen, assistant vice president of the association’s national policy program.

“The challenge with diesel is that it takes fleets so long to turn over,” Nolen said. “Things like tractors, power generators often are not used enough to have to be replaced often, so the old equipment continues to be a serious health concern.”

Delzell said there are no efforts at Caterpillar to encourage recycling old equipment but improvements in fuel economy could be a natural incentive.

EPA officials did not respond to EHN's repeated requests for interviews for this story.

“The challenge with diesel is that it takes fleets so long to turn over. Things like tractors, power generators often are not used enough to have to be replaced often, so the old equipment continues to be a serious health concern.” Janice Nolen, American Lung AssociationThe last phase of the rules will kick in next year, applicable to engines larger than 750 horsepower, which are used in mining trucks, locomotives and ships.

“We just hope the standards will allow us to sell these engines before they change the damn rules again,” Woodruff said. “I’m all for standards, but there will be companies that will cease to exist if the regulations continue.”

Market trends suggest that diesel, which has been the preferred power source of heavy-duty engines since the 1920s, is here to stay.

The diesel engine industry generates about $143 billion annually worldwide, and sales of both on-road and off-road diesels are expected to grow about 6.7 percent over the next two years, according to a report from the Freedonia Group, a market research company. 

“Diesel engines power many aspects of our economy,” Schaeffer said. “Getting the industry clean has not moved people away from it. If anything, it’s provided the platform for it to be competitive in the future.”

Commissioner Putnam, I’m Hungry for Leadership

Secretary of Agriculture Adam PutnamI’m so sick of political doublespeak in Washington and Tallahassee. It’s time that we the people get serious about holding our elected representatives accountable. Here is one that needs our attention: Florida Commissioner of Agriculture, Adam Putnam.

Adam is a bright and very ambitious young man who wants to be Florida’s Governor one day. He was a rising star in Congress and then came back to Florida to run for statewide office as the Agriculture Commissioner. He brought the orphaned Florida State Energy office under the Department of Agriculture, because newly elected Governor Rick Scott had no interest in energy issues (and still doesn’t). Adam’s good intentions to try to advance real energy policy in Florida were quickly dashed by the big utilities’ influence, which now controls his energy agenda. In fact his Chief of Staff worked for Progress Energy and his General Council is married to a Florida Power and Light lobbyist. Sadly, in order to justify the lack of leadership on his watch, he claims there is “no appetite” for renewables in Florida.


The Bottom Line: Efficiency Goals Should Be A Part Of Strategic Planning

Jessica Rose - Incite SutainabilityEvery director and executive of a national business should be using efficiency goals as a part of their strategic planning. What's not to love about water and energy efficiency programs? They can strengthen your brand, improve team loyalty, reduce overhead and hedge risk.

Let's talk about risk. In a time of rapidly changing energy resources, increasing water scarcity and the unknowns of emission trading looming overhead, it would be foolish of a business executive not to consider energy and water efficiency opportunities in their portfolio. Big businesses know this. That's why the 3Ms, PepsiCos and Colgate-Palmolives of the world have been systematically enacting efficiency and monitoring programs for many years.


An honest look at sustainability

The term “sustainability” is heard more every day – from the impassioned pleas of those protecting nature, to the halls of corporate America, the clinics of spin doctors and TV ads. But whenever words become stylish, thus over-used, they tend to confuse and mask rather than inform and inspire.


Save Time And Money With A Corporate Sustainability Mindset

Corporate Sustainability is a business technique that creates employee value and long-term customers with a green strategy. This way of running a business develops less waste and repurposes items in the workplace so that the environment is still productive, but not wasteful in any sense.


Legal Experts Reject Food Industry Claims that GMO Labeling Laws Are Unconstitutional

For related articles and more information, please visit OCA's Millions Against Monsanto page and our Genetic Engineering page.

The food industry is playing every conceivable angle in its quest to keep labels off foods that contain genetically modified organisms (GMOs)—including, according to a leaked document, threatening to sue the first state that passes a GMO labeling law. (Maine and Connecticut passed GMO labeling laws in 2013. But both have “trigger” clauses that prevent the laws from taking effect until at least four neighboring states, with a combined population of 20 million inhabitants, pass similar labeling bills).
