This project would have powered over a million homes and made a huge dent in New Zealand’s greenhouse gas emissions. It is not happening now because of a group of NIMBY activists and the Environment Court’s ruling.

This is a huge blow, in itself, to renewable and wind energy proponents, but it also brings concerns for future wind energy projects.

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

Editor’s Note: This is a guest contribution by Nancy Gioia, Ford’s Director of Sustainable Mobility Technologies and Hybrid Vehicle Programs.

It’s clear electric vehicles (EVs) will be part of the transportation mix of the future.

President Obama has set ambitious goals for wide-scale adoption of EV technology. Advances in battery technology will help bring more electrified vehicles to market for consumers and the desire to reduce CO2 emissions has increased attention on transportation alternatives like electric vehicles and plug-in hybrids.

We live in an era where compute capability is ubiquitous, whether it be on a smart phone or mobile computer, and where “the cloud” can be accessed from anywhere.

In parallel, the ever-improving energy and carbon-efficiency of computers creates new opportunities to trade off atoms for bits, also known as de-materialization, and to substitute carbon-intensive activities, such as transportation, with tele-presence.

Here in Intel’s Eco-Technology group, we’re trying to learn precisely where these trade-offs exist, and under what conditions society can achieve net-positive outcomes, by harnessing technology in more environmentally beneficial ways. To that end, together with Microsoft’s sustainability group, we asked Dr. Jonathan Koomey, visiting professor at Yale’s School of Forestry and Environmental Studies and an expert in energy conservation technology, economics, policy and global climate change, to undertake a study of the environmental tradeoffs, between purchasing music in the traditional fashion (on CD from an online or brick and mortar store), versus purchasing and downloading the digital files.

Brown cloud near Pune, India

The legendary glaciers of the Himalayan and Hindu Kush mountain ranges have been losing volume at an increasing rate over the past twenty to thirty years. And over this same time period, much data has piled up confirming the role of increased CO2 emissions in global warming trends. Given this, it would be “natural” to assume that CO2-induced warming was also to blame for the glacial melting. But it turns out that much stronger evidence points to the impact of “brown cloud” events.

There have been other extensive brown cloud events elsewhere, such as in Central and Eastern China (which first made headlines back in 2005). They can be several miles wide / long, and extend hundreds of meters or more high. The clouds would be more aptly described as massive, moving blankets of thick haze (similar to smog). They typically last anywhere from a few days to a week before they dissipate. The clouds are indeed lethal to some (asthmatics, elderly, young children, those with bad hearts) and have also been known to suffocate livestock.

I have been in Sao Paulo this week at Sustentavel 2009, perhaps the premiere Sustainable Development event in Brazil, if not all of South America. At the opening I represented the World Business Council for Sustainable Development and then on the first day of presentations I participated in the main climate change panel session.

What is clear is that there is a passion in Brazil for sustainability – from the huge issues they face in the Amazon region to the road congestion in Sao Paulo. Talking with delegates at Sustentavel, it is also clear that the country faces an interesting future in terms of greenhouse gas emissions.

World Fertility Rate Map

The current world population is approximately 6.5 billion people and growing. By or before 2050, that number will grow by almost 50% to 9 billion. With the availability of birth control and better education rates for women being higher in developed (industrial or post-industrial) nations, most of this increase is projected to come from the developing  world–those nations that are just now making significant progress away from exclusively agrarian societies, and towards full industrialization.

And despite the prevalence of fatal diseases, civil wars, and high infant mortality rates (note: the US has the highest infant mortality rate of any developed country), most of these developing countries continue to show population increases–especially as more effective medicines and health education (via government and private sector programs) become available.

Wastewater treatment facilities end up dumping a lot of mud that is extracted from the in-flowing water. And, like everything else, that mud takes up space. Space that could be used for other things, even at the dumping yards. But researchers from the Rovira i Virgili University (URV) have suggested, and successfully shown, that the waste mud doesn’t need to be taken to a dumping ground; rather, it can be used as fuel.

This is great news for industries that are trying to comply with the Kyoto Protocol and cut CO2 emissions. It is also good news in a world that is trying to shake itself free of the addictions to traditional oils and coals.

Carbon Capture and Storage (CCS) has the potential to cut global Co2 emissions dramatically. We’re talking huge cuts. It has been estimated that a plant implementing CCS can cut emissions by 80-90 percent compared with a plant that doesn’t use CCS. Sounds great, right? Well, there are some some problems.

Cost is the number one challenge that CCS faces. “Applying it would significantly increase the cost of electricity beyond what society is likely willing to pay,” said Sarah Forbes,  a World Resources Institute Senior Associate. Another challenge is that no fully integrated demonstrations have taken place. The pieces have been tested individually, but the entire puzzle is yet to be seen.

Forbes describes CCS and its current challenges in more detail:

As Congress engages in the major debates surrounding climate and energy legislation, a broad coalition of consumer, economic and environmental advocacy groups has published a report on the substantial consumer savings that stronger energy efficiency and renewable energy standards would bring.

Published by the Consumer Federation of America, Environment America, Energy Future Coalition and the American Council for an Energy-Efficient Economy, the report (pdf) indicates that studies of the technical potential for easily implemented efficiency improvements show efficiency could lower demand by as much as 30 percent in states from all regions of the U.S. at costs well below the current cost of electricity.

Most of us are familiar with the idea of carbon dioxide (CO2) from industrial development leaching into the atmosphere, causing global warming. The effect of CO2 on ocean temperatures and acidification is much less well publicised, but just as worrying. In fact, it’s a potential cause of famine.

Leading experts at the 2009 Aspen Environment Forum called ocean acidification caused by high levels of CO2 emissions a “planet changer”, and predicted that all coral in the ocean would be in danger of dying off by mid-century if we continued to burn fossil fuel at our current rate.

Ken Caldeira of Carnegie Institution, Martin Hoffert of New York University, and Dawn Martin of SeaWeb told attendees at the session “The Ocean Carbon Cycle: Facing the Damage” that we haven’t taken the issue seriously enough, and expressed dismay at the lack of media coverage for such an important issue.

“People would be more upset if you told them that their favorite TV show was canceled than if you told them that entire biomes would disappear.” - Ken Caldeira, Carnegie Institution

Last month, The Times said that two typical Google searches generate the same amount of carbon emissions that are generated by boiling a kettle, “about 15g of CO2.”  This week Zaproot focuses on this and other information in its stranger than truth show “That’s Just Weird.”

As much as you might think that living life online saves a vast amount of resources, the IT industry contributes to about 2% of carbon emissions (The Times). When it comes to companies like Google, the very fact that it generates more than 200m internet searches daily, provokes concern regarding electricity consumption and greenhouse gas emissions. Although Google claims to be committed to sustainability, the truth is that typing in a term into a Google search bar, offsets many competing servers to search for content related to that particular term. All too often the search is generated by the ‘fastest’ rather than the ‘most efficient’ server.

Aside from the overriding need to stabilize atmospheric carbon dioxide (CO2) levels to stabilize climate, there are several other compelling reasons for countries everywhere to restructure their transport systems, including the need to prepare for falling oil production, to alleviate traffic congestion, and to reduce air pollution. The U.S. car-centered transportation model, with three cars for every four people, that much of the world aspires to will not likely be viable over the long term even for the United States, much less for everywhere else.

The shape of future transportation systems centers around the changing role of the automobile. This in turn is being influenced by the transition from a predominantly rural global society to a largely urban one. By 2020 close to 55 percent of us will be living in cities, where the role of cars is diminishing. In Europe, where this process is well along, car sales in almost every country have peaked and are falling.

With world oil output close to peaking, there will not be enough economically recoverable oil to support a world fleet expansion along U.S. lines or, indeed, to sustain the U.S. fleet. Oil shocks are now a major security risk. The United States, where 88 percent of the 133 million working people travels to work by car, is dangerously vulnerable.

Concerns now being expressed do not relate to the issue of the tiny quantities of mercury in the bulbs that was raised a year or two ago (largely misguidedly - while in environmental terms far more mercury is released into the environment by the manufacture of traditional bulbs). Instead they focus on potential difficulties for partially-sighted people.

A recent survey of drivers found that 2,150 tons of CO2 are generated by UK motorists warming up their cars in the morning, creating the equivalent CO2 emissions of three 747 flights from London to New York each day.

“Everyone is now familiar with simple energy saving tips like switching off a tap, turning off lights and recycling but it seems many people’s green intentions go out the window when they are faced with a cold start in the morning. Our research has shown that an estimated 2,150 tonnes of CO2 and 21,450MW  of electricity will be wasted each cold morning across the UK.” - Lucy Bailey, ibuyeco spokesperson

“Now should be environmental vegetarianism’s big moment. Global warming is the single biggest threat to the health of the planet, and meat consumption plays a bigger role in greenhouse gas emissions than even many environmentalists realize.” - Ben Adler

This quote above is from an article by Ben Adler in American Prospect, titled “Are Cows Worse Than Cars?”. It really stands out as a reminder of the clearly divided environmental movement. By and large, the movement towards environmental sustainability has just plain ignored the impact that dietary choices have on global warming. Curious, isn’t it?

On the one hand, we can support cleaner energy, buy more efficient cars, and reduce our consumption of products derived from petroleum, and yet with our other hand, eat a burger that has a carbon footprint bigger than most SUVs.

“I think it’s amazing that even the greenest of green liberal environment activists, the vast majority of them tend to consume meat at the same rate as people who think global warming is a hoax. Meat consumption seems to be the last thing that progressive people address in their lifestyle. If I had a nickel for every global warming conference that had roast beef on the menu, I’d be rich.” - Mike Tidwell, director of the Chesapeake Climate Action Network
