UXBRIDGE, Canada, Apr 22 2014 (IPS)

Hopefully, on Earth Day today, high-level ministers from all countries are thinking about what they can bring to the table at a key set of meetings on climate change in early May.

This will be the first opportunity for governments to discuss their proposed climate action plans in light of the final Intergovernmental Panel on Climate Change (IPCC) report released last week.

“There is a clear message from science: To avoid dangerous interference with the climate system, we need to move away from business as usual.” — Professor Ottmar Edenhofer

That report warned that carbon dioxide (CO2) emissions from burning fossil fuels are still rising far too fast, even with more than 650 billion dollars invested in renewable energy in the last three years. However, over the same time period even more money was invested in getting more fossil fuels out of the ground.

The latter investment is keeping humanity and the planet locked onto a devastating path of a global temperature increase of four to five degrees C, the IPCC’s Working Group III report warned.

Scientists and economists say that unlocking ourselves from disaster will require a massive reduction in emissions – between 40 percent and 70 percent – by midcentury. This is can be readily accomplished without inventing any new technology and at a reasonably low cost, reducing global economic growth by a comparatively tiny 0.06 percent.

“It doesn’t cost the world to save the planet,” economist Professor Ottmar Edenhofer, who led the IPCC team, said at a press conference.

It does mean an end to investments in expanding fossil fuel infrastructure as the annual growth in CO2 emissions from burning oil, coal and gas must peak and decline in the next few years. The atmosphere already has 42 percent more CO2 than it did prior to 1800.

This extra CO2 is trapping more heat from the sun, which is heating up the oceans and land, creating the conditions that spawn super storms and extreme weather. And it will do so for the next 1,000 years since CO2 is a very durable molecule.

Current emissions are adding two percent more heat-trapping CO2 each year. That will push humanity’s ‘CO2 contribution’ to 50 percent four years from now.

“There is a clear message from science: To avoid dangerous interference with the climate system, we need to move away from business as usual,” Edenhofer said.

The IPCC’s first report released last September as part of its Fifth Assessment Report (AR5) clearly stated once again that the climate is changing rapidly as a result of human activity and urgent action is needed.

This was followed last month with a strong confirmation that climate impacts are already occurring on every continent and throughout the world’s oceans. This second report warned that one of the major impacts will be declines in food production unless emissions begin to decline.

The fossil fuel sector, the richest in human history, appears to be ignoring the IPCC warnings.tar sands flag copenhagen sml0000

Earlier this month, oil giant ExxonMobil issued a report to its shareholders saying it does not believe the world will curb CO2 emissions and plans to extract and sell all of its 25.2 billion barrels worth of oil and gas in its current reserves. And it will continue investments hunting down more barrels.

“All of ExxonMobil’s current hydrocarbon reserves will be needed, along with substantial future industry investments, to address global energy needs,” said William Colton, ExxonMobil’s vice president in a statement.

The IPCC agrees oil, gas and coal will still be used in future but there is a CO2 maximum to have a reasonable chance of staying below two degrees C. That fossil energy cap won’t be enough to meet global energy needs so Working Group III recommends shifting to large-scale bioenergy and biofuels, waste incineration, nuclear power and carbon capture and storage (CCS).

These energy sources are controversial and risky. Large-scale bioenergy and biofuels needs huge areas of land and vast quantities of water and will compete with food production.

Studies show ethanol results in more emissions than burning gasoline. Even making ethanol from the leftovers of harvested corn plants released seven percent more CO2 than gasoline while depleting the soil, a new study revealed in Nature Climate Change this week.

The IPCC acknowledges bioenergy and biofuels can increase emissions, destroy livelihoods and damage the environment, says Rachel Smolker of Biofuelwatch, an environmental NGO.

“It is a shame they put so much stock in something that would make things worse rather than better,” Smolker told IPS.

Given all this, what climate action plans are governments going to propose when they meet in Abu Dhabi on May 4 and 5th? This is an informal ‘put your cards on the table’ regarding a new set of commitments on emission reduction targets and action plans to be made public at the U.N. Climate Summit in September.

Current reduction targets will not avoid four degrees C, most experts agree.

In hopes of getting countries to increase their reduction targets, U.N. Secretary-General Ban Ki-moon asked governments to bring new proposals to New York City in September. With the current U.N. Climate Change Convention meetings deadlocked on key issues, the New York Summit is intended to kick-start political momentum for an ambitious, global, legal climate treaty in 2015.

The May get-together titled the “Abu Dhabi Ascent” is the only meeting before the Summit where governments, and invited members of the private sector and civil society will come together to explore how to get ambitious action to reduce emissions.

The Abu Dhabi meeting will be a window into the future of humanity: ascent or descent?

Why care about your water footprint?

"Your water footprint" by Stephen Leahy

Margaret Badore (@mbadore) Science / Clean Water

November 18, 2014

We learn in elementary school that water is in a constant cycle of evaporation and precipitation, making our crops grow and flowing from rivers into oceans. While the amount of water on Earth remains fairly stable, its distribution around the globe is changing, and this change is being accelerated by human activities.

A new book, “Your Water Footprint,” by environmental reporter Stephen Leahy, takes a close look at the “virtual water” that surrounds us in everyday life. This isn’t just the water we use to boil pasta or take a shower, it’s the water that’s used to grow our coffee beans and power the local energy plant. As the demand for this kind of water increases, the more threatened our access to fresh water becomes. At the same time, pollution makes vast amounts of water unusable.

I had the opportunity to catch up with Leahy over Skype.

TreeHugger: What were your goals for writing this book?

Stephen Leahy: To help people understand this other aspect of water that we use, that we don’t see. This virtual water concept: the water it takes to make things, the water it takes to grow our food, to make our products, to make our clothing. This is that unseen water that we don’t think about, and because we don’t see it, we’re not really aware of it.

It’s an enormous amount of water that we end up consuming every day without realizing it.

TreeHugger: The book is very number heavy, which makes it easy to compare how much water is used in different things. How did you go about finding all the data?

Leahy: It was a nightmare actually, the numbers. Especially for a person who’s a writer, not a numbers guy.

What I did, and this was based on covering science for many years, was figure out a baseline. Who is the best researcher? Who has the best data collection of water footprints? It turned out to be the University of Twente in the Netherlands, and they actually pioneered the concept of water footprints. They’ve developed a whole methodology about how you calculate it, and they’ve done piles of studies of the various water footprints of various products. Sometimes not in the way we think of products. So, they would do a water footprint for wheat, but that doesn’t necessarily translate into a burger bun or bread, so I did that. I figured out how much wheat goes into a loaf of bread and did that part of the calculation myself.

So, University of Twente was a godsend, because there are lots of different ways of calculating water footprints, and there’s different numbers out there.

TreeHugger: In the introduction, you discuss this concept of the “water-food-energy nexus.” I’m hoping to can tell us a little more about that.

Leahy: Most people realize that we need water for food, but what most people don’t understand is that we also need water for energy. There’s no form of energy that doesn’t need water. We have a growing population, and a growing shift in diets from vegetable-based to meat-based, which uses a lot more water. At the same time, there’s a billion people who don’t have access to electricity and they of course want to get electricity. As we look to produce more energy and more food, we’re going to need more water. This is the point of the nexus: we don’t have enough water to do all that in the future.

TreeHugger: So, looking forward, we need to reduce our water footprint. I think a lot of our readers are going to be familiar with the concept of reducing a carbon footprint, and in a lot of ways these concepts overlap. So, from your perspective, what are the ways the two footprints don’t overlap?

Leahy: Certainly on the energy side they overlap a lot. But on the food side, that’s probably the best example. If you switch from a meat-based diet to a vegetarian diet, you could reduce your daily water footprint by 1,300 liters. So, that’s an enormous amount of water when you put it over a year, nearly half a million liters in savings.

The other thing you can do is swapping beef for chicken. Swapping beef for chicken for a family of four would save 900 liters of water.

Food waste is another example, 38 to 40 percent of food in North America is wasted, and that’s a huge amount of water embedded in that food. The “best before” dates are actually problematic in that regard, because it doesn’t really mean the food is bad, it just means the company’s not guaranteeing the flavor.

TreeHugger: I also wanted to ask you about how you think about the trade-offs between the water impact of a product and some of the other impacts of a product. I was thinking about tee-shirts, because I write about clothes a lot. So, on one hand, we could say cotton is natural, it can be low in toxins if we use natural dyes and it’s biodegradable. On the other hand, cotton has a high water footprint. Then if we look at polyester, it has a lower water footprint, but there are concerns about it releasing toxins as it breaks down and contributing to micro plastic pollution. So, how do you look at these kinds of trade-offs? Do you have advice for weighing them?

Leahy: This gets a little bit complicated, because a big number for a water footprint is not necessarily indicative of something that’s bad. If you’re in a water-rich area and need a lot of water, and you’re not polluting this water, that’s going to be okay.

It’s kind of site-specific and product-specific, so this does make it quite a bit more complicated. On the clothing side of things, if you’re growing cotton in a country that has reasonable amounts of rainfall and preferably it’s grown organically, that is it’s grown without pesticides and chemicals, you’re greatly reducing the contamination of water. And if you’re using rain-fed cotton and not depleting an underground source, those are some conditions under which we could talk about products being truly sustainable, because you could continue this for quite a while.

TreeHugger: So, as we look to the future, there are many areas that will soon be facing the collapse of “water bubbles.” Do you think we need to see a shift in water policies or do we need to reduce our personal water consumption? Or is it both?

Leahy: It’s both. From a government policy point of view, water needs to be respected a lot more in terms of managing it long-term. There are places like California that don’t have any rules about how much ground water you can take. Anyone can take as much groundwater as they like—and that’s not uncommon.

The other side of course is consumers. I think consumers need to raise the issue more with both their elected leaders but also the industry. Some industries have responded, Levi’s has greatly reduced their water use for the production side, although it’s not exactly waterless since it takes a lot of water to grow cotton. So, that’s a role for consumers: asking, ‘Where is this product made? Where did it come from?’

Because there are certain things that don’t make any sense. For instance, Egypt is the number two exporter of oranges in the world. Egypt, well it’s is basically a desert, so why are they exporting all these oranges? There are actually all these economic reasons that don’t make any sense from a sustainability point of view. So consumers can make a decision and say, I’m not going to buy a product that requires a lot of water from the desert, because that’s just dumb.

The point about the virtual water is that we have very little without water. So, we’re extraordinarily dependent on water in ways we just don’t realize. And yet, we under-price water, water is very cheap, and water doesn’t get the respect it deserves.

This interview has been shortened and condensed.

Water is far more valuable and useful than oil

Average water footprint of bottle of cola
Average water footprint of bottle of cola

The water footprint of a half-litre bottle of water is 5.5 litres – yet well over a billion people live in areas with chronic scarcity

By Stephen Leahy

I have a confession: I knocked back 320 pints at the pub last night. I actually only had two shots of a decent single malt but it took 320 pints of water to grow and process the grain used to make the whisky. That’s a whole lot of water considering the average bathtub holds 60 to 80 litres.

Even after 20 years of covering environmental issues in two dozen countries I had no idea of the incredible amounts of water needed to grow food or make things. Now, after two years working on my book Your Water Footprint: the shocking facts about how much water we use to make everyday products, I’m still amazed that the t-shirt I’m wearing needed 3,000 litres to grow and process the cotton; or that 140 litres went into my morning cup of coffee. The rest of my breakfast swallowed 1,012 litres: small orange juice (200 litres); two slices of toast (112 litres); two strips of bacon (300 litres); and two eggs (400 litres).

Water more valuable and useful than oil

Researching all this I soon realised that we’re surrounded by a hidden world of water. Litres and litres of it are consumed by everything we eat, and everything we use and buy. Cars, furniture, books, dishes, TVs, highways, buildings, jewellery, toys and even electricity would not exist without water. It’s no exaggeration to say that water is far more valuable and useful than oil.

front cover resized1A water footprint adds up the amount of water consumed to make, grow or produce something. I use the term consumed to make it clear that this is water that can no longer be used for anything else. Often water can be cleaned or reused so those amounts of water are not included in the water footprints in the book. The water footprint of 500ml of bottled water is 5.5 litres: 0.5 for the water in the bottle and another five contaminated in the process of making the plastic bottle from oil. The five litres consumed in making the bottle are as real water as the 500ml you might drink but hardly anyone in business or government accounts for it.

The incredible amounts of water documented in Your Water Footprint are based primarily on research done at the University of Twente in the Netherlands, where Arjen Hoekstra originated the concept of water footprints. The amount consumed to make something varies enormously depending on where the raw materials come from and how they are processed. Wheat grown in dry desert air of Morocco needs a lot more water than wheat grown in soggy Britain. For simplicity, the amounts in the book are global averages.

One of the biggest surprises was learning how small direct use of water for drinking, cooking and showering is by comparison. Each day the average North American uses 300 to 400 litres. (Flushing toilets is the biggest water daily use, not showers.) 400 litres is not a trivial amount; however, the virtual water that’s in the things we eat, wear and use each day averages 7,500 litres in North America, resulting in a daily water footprint of almost 8,000 litres. That’s more than twice the size of the global average. Think of running shoes side by side: the global shoe is a size 8; the North American a size 18. By contrast, the average water footprint of an individual living in China or India is size 6.

Peak water is here

Water scarcity is a reality in much of the world. About 1.2 billion people live in areas with chronic scarcity, while 2 billion are affected by shortages every year. And as the ongoing drought in California proves, water scarcity is an increasing reality for the US and Canada. Water experts estimate that by 2025 three in five people may be living with water shortages.

While low-flow shower heads and toilets are great water savers, the water footprint concept can lead to even bigger reductions in water consumption. For example green fuels may not be so green from a water consumption perspective. Biodiesel made from soybeans has an enormous water footprint, averaging more than 11,000 litres per litre of biodiesel. And this doesn’t include the large amounts of water needed for processing. Why so much water? Green plants aren’t “energy-dense,” so it takes a lot of soy to make the fuel.

Beef also has a big footprint, over 11,000 litres for a kilo. If a family of four served chicken instead of beef they’d reduce their water use by an astonishing 900,000 litres a year. That’s enough to fill an Olympic size pool to a depth of two feet. If this same family of opted for Meatless Mondays, they’d save another 400,000 litres. Now they could fill that pool halfway.

We can do nearly everything using less water. It’s all about smart substitutions and changes, rather than sacrifice and self-denial, but we can’t make the right choices unless we begin to see and understand the invisible ways in which we rely on water.
