The hidden price of going green

This blog post is about something as girly as shopping. Impulse shopping even. In a nationwide trinkets store called Søsterne Grene (The Grene sisters) I stumbled over a table filled with different kitchen utensils. They were all made of bamboo, and even better, they were all made of sustainably grown bamboo! And it was really cheap, something you value when you’re on a student budget. There was cutlery, plates, cuttings boars, pallets, salad tongs and even those tiny plates you use for your chopsticks when you eat sushi.

Wow, I thought, this is everything I need, and more! And it’s all from sustainably grown bamboo. The entire table of stuff is from sustainably grown bamboo. And when I reached this sentence, my smile faded. The entire table of stuff is from sustainably grown bamboo. Not sustainably produce, not sustainably transported. I won’t question that the bamboo is grown with attention to the use of pesticide and  good working conditions, or that no illegal deforestation took place. I’m sure the bamboo pallet in my hand had a great and sustainable growth. But that pallet has been on a long journey from it sprouted out of the ground till it ended up in my hand. Now, I do not have the knowledge of this particular product, but let’s break down some of the possible steps that this pallet has been through.

Growth: sustainable (yet, information about it is not transparent). I think I recall a ‘made in China’ sticker on one of them.

Harvest: For an industrial production this size, I’m willing to bet my hat that it’s not harvested by hand. More likely it’s harvested with big fuel consuming machinery. If it’s produced in a 3rd word country, then there are probably limited restriction in relation to particle filters and energy consumption.

Transportation: Again, big heavy machinery. Trucks, trains maybe even freighters; all of these consume fossil fuel.  

Production: Here lots of machines cut and sand the bamboo. Water (too often drinking water in heavy quantities) is used to clean the dust and dirt of the raw material, as well as the cut product. The finishing might be done with oils i.e. sesame or coconut oil (are these sustainably produced with regards to illegal deforestation?), or they might be finished with lacquer (I wonder what chemicals are in that). Seeing as we don’t know anything about the production method, we don’t know if the production process had good working conditions for the employees, or if the processing chemicals are toxic or environmentally hazardous.  

Packaging: The utensils are given individual stickers. The cutting boards are wrapped in plastic. Some of the utensils are packaged in individual cellophane bags. Stickers, wrapping plastic and cellophane have all been produced with the help of energy consuming machinery, chemicals, and at some point, crude oil.  
The now individually wrapped and price tagged products need to go in boxes. Boxes and more wrapping. If it’s an older packaging procedure this could involved Styrofoam, which releases toxic gasses when burned. If it’s a newer packaging procedure the Styrofoam will most likely be replaced with paper. The packaging product in-between these two, is of course bubble wrap, something I shamefully admit I am big fan of. Pop, pop, pop!  

Shipping: Yep, you guessed it; Trucks, train and ships. All very fossil fuel consuming

And then I’ll skip elegantly through distribution to warehouses and the re-distribution to the store, both of which requires more transportation. And now the pallet is in the store. Lying there all pretty and inviting with its ‘sustainably grown’ label on it, screaming “buy me! I’m sustainable and cheap!”



But we don’t see the full price. We don’t see the other raw materials in use, we don’t see the energy consumption and we don’t see the working conditions for those involved. We only see the price tag and the word sustainable. So why do we want to buy it?  

There’s a lot of psychology and sociology underneath the choice of buying sustainable, and I will get back to them in a later post. The following is the ultra short version:
We have in recent years been told by society that buying sustainable and “going green” is, for various reasons, the right thing to do, and we feel like a good person when we perform “green acts” i.e. save electricity, eat organic food, use biodegradable fabric softener or buy pallets from sustainably grown bamboo. And the psyche likes to feel like a good person and likes to show itself as a good person. In Britain there is a trend happening now; People are buying and installing solar panels of their roof in massive numbers. Great right? The only problem is that homeowners are primarily installing them on the roof side facing the street, instead of placing them on the roof side which is actually getting sun, resulting in very low efficiency of the solar panels. A much higher efficiency could be obtained by installing the solar panels on the roof side facing the sun, not the one facing the street. Why then install them on the street side? To show your neighbors that you are a good person because you use renewable energy.

So how do we make the right choice if it is not necessarily the same choice that makes us feel like good people? (Also, I promise to deliberate further on this in a later post, but at this point you have been reading for a while so I’m not gonna push it). I will here give you the example of milk. Milk is used in most household and has a huge global distribution with a ton of different varieties. I use it in my coffee. 

Depending on where you live, milk mostly comes in a conventional version and an organic version. The conventional milk is cheaper than the organic milk and the price difference varies a lot depending on where you live and shop. In Copenhagen, Denmark where I live, every store has organic milk. From organic mini stores and supermarkets, to 7-11’s and gas stations. Organic milk is a very common sight in Denmark, so common that every 3rd carton of milk sold in Denmark in 2010 was organic. And this is despite the fact that organic milk is roundly 25-30% more expensive than regular milk. Studies suggest that buying 1 liter of organic milk, instead of conventional produced milk, will save 200 liters of groundwater from coming into contact with pesticides because the livestock is only allowed to eat organically produced feed, meaning no pesticides are used for the fields that grow the grain used for the feed. Also organic farming discharges 40% less nitrogen than conventional farming, organic milk is said to contain 60% more polyunsaturated fatty acids, have a higher level of vitamin E, and emit 10% less CO2 than conventional produced milk [Link] (If you would like to see English scholar articles about this subject, please contact me). So in short: Organic milk is in the “good person” folder and 1/3 of the Danish population buys it, even though is pricier than other products. How did milk win the marked like that? As said before, milk is a household product and most people see it as a regular object on the shopping list. In other word, you were going to buy it anyway. You choice is whether to spend the 30% more and by doing so, feeding the ‘good person’ feeling. You don’t have to change a major habit, you just change brand. Of course the organic milk revolution didn’t happen overnight. It took a lot of dedicated individuals and stakeholders to push for government initiatives and regulations. Because of the controversy regarding standardizations and regulations that were needed for introducing organic milk to the mainstream market, it was also one of the fist organic products to be thoroughly tested and inspected. This lead to a sizable knowledge pool based on quantitative methods, which was then distributed to the general public. In other words, the knowledge about  the positive environmental aspects of organic milk, a longer time to spread though the collective knowledge of society and become socially accepted as ‘the right choice’.

So what can we learn from the pallet and the milk? If we are to make choices that benefit not only our own feeling of self good, but the environment as well, we need more knowledge about the products we buy, or don’t buy. There is a need for a solid foundation of empirical knowledge about the product. A product that has the label ‘sustainable’ on it, it not necessarily a sustainable choice, just as organic milk isn’t necessarily just an expensive version of an ordinary dairy product. With the global market as intertwined as it is, mapping all the different steps in the production chain is almost impossible, but in those steps we lose the actual price of the product. 

There is a need for more transparency in regards to the production of our goods, and to promote this we as consumers need to not be dazzled by a shiny “sustainable” object. Our first step is to think, to be critical in our choices, and let those choices be base on knowledge instead of assumptions. “But that’s so hard…” Yes, yes I know, but you also feed the I’m-a-good-person-feeling by making smart choices, not by buying whatever has a green label on it. 
There is no easy answer and no obvious solution on how to be sustainable. But we need to be conscience about these questions and the choices in our daily lives.

And now you might be wondering if I bought the Sustainable pallet. I didn’t. I decided that my old pallet at home was just fine, because it had already been produced and bought and is after all still a functional pallet. But some day that pallet will break and I will need a new one, and when that day comes, I’ll look for a somewhat sustainable one.

3rd world problems in a 1st world country - why more attention to mitigation is needed.

Denmark has in recent years had above average rainfall resulting in above average flooding, many of them record breaking. Like the extreme rainfall of July 2nd 2011 in Copenhagen that resulted in massive flooding all over the city and left 50.000 households without hot water. That amount of rain was described as a statistical abnormality, one that should only occur every 300-500 years (Director of water and sewage in Copenhagen’s energy department). The picture below is from that flooding.



On August 14th Copenhagen again experienced heavy rainfall, this time with less flooding, but it was enough to damage the worn and old sewage system, and the fresh water pipelines came into contact with rain and sewage water. On the 18th of August a warning was issued in Copenhagen. Doe to water contamination citizens must boil the water before drinking it, showering in it or using it for dish or cloth washing. On the 23rd of August the problem still affected 40.000 citizens which still had to boil their water. It has been underlined that this was a special event, an unlikely combination of heavy rain and a malfunctioning pipeline. A double accident if you will. From a risk management view this isn’t something that should be feared because it’s too unlikely. 

Human beings have the flaw that we have trouble comprehending the damage of, and therefore ensuring ourselves against, a double accident. Another example of this is the near catastrophe that happened at the Fukushima nuclear power plant in Japan, March 2011. The plant had been insured against earthquakes and it had been insured against tsunamis and floods, but it hadn’t been insured against first being hit by an earthquake and then a tsunami. The thought of such a double accident was incomprehensible and therefore not planned for. On a much smaller scale, it’s the same with sewage systems. A busted pipe combined with a flooding. Unlikely, and therefore not planned for.


Denmark is a 1st. word country, one that isn’t used to water contamination or having to import drinking water. We have good infrastructure and good health. Denmark is a well-oiled machinery that ensures its citizens an almost sickening level of security and comfort. But we have to make some swift decisions if we want to keep that up. The sewage problem must be delt with. The pictures below are from my building block as it is gearing up to change some of the bad pipes. Sights like these are common in Copenhagen these days.

Meanwhile the electoral race is on, and the hunt for votes has got the political parties presenting one elaborate plan after the other on how to best serve citizens. But not a single party or candidate has mentioned the sewage problem. It’s commonly known that the added run-of from re-pavement of the city, combined with heavier rainfalls, exceed the capacity of the sewer, but still no one is addressing the problem. Mitigation needs to have a place on the public agenda next to health care and taxes, because ignoring the need for mitigation will only ad costs to our health and our national bugged. For once we actually need to talk more about the weather and how to deal with it.

Sustainable and the City - An eco girl in New York

The following argues that there will be no transformation in the energy sector, until there is both a need in society, a willing government, and a public demand.

Being a sustainability geek, visiting New York City was a dream come true. New York City has one of the most ambitious green infrastructure plans in the world –and they have a lot of green roofs, which I absolutely love. In fact, they plan to put green structure on 10% of NYC’s non permeable surfaces by the year 2030, this being in the form of green roofs, pocket parks and the likes. Green structure will function as both stormwater management, relieving stress on the sewer system, a rain water purifying filter and, where the green structure is in the form of a green roof, will save energy on both heating and cooling. And the best part, it’s cheaper than fixing up the sewer system. Hurray! So little Miss ecogeek here was thrilled about visiting this magical green structure wonderland. I went there in late December 2010, 2 days before the big blizzard hit (lucky me for not stranding).

Me in NYC -yay!

But if you’ve been to NYC in the winter, or any American city I fear, you will know that it is draughty as hell. I was shocked! Shocked and very cold. No matter what building I entered I felt that draught. I started becoming obsessed with it, spotting the single layered windows, and the non sealing doors, wondering how much, if any, insulation was in the walls. My green wonderland had turned out to be one big waste of energy. Not mine, but the inhabitant’s of New York. I kept thinking about all that heat and hence all the money slipping through the endless cracks, and unsealed doors in the buildings. And to make matter worse, the buildings are heated by a local furnace or electrical heathers which are both really energy inefficient compared to a heat- and power plant, where waste is burnt to create heating and electricity. Instead the NYC waste is going to landfill, and the buildings are being heated with non-renewable, and costly oil! My eco heart was broken. How could this be?

I was fortunate to have lunch with a journalist one day, and we had a talk about it. I told him about the conditions in Denmark where we, as mentioned in a previous post, have fairly good insulation in our buildings. He said to me, "Yeah, but we didn’t have any wars, so we didn’t need to rebuild our city, and therefore didn’t put in more insulation, or double layered windows." Then the lunch ended and so did the conversation. But I couldn’t let it go because well, Denmark didn’t have wars either. In Denmark, land of the cozy, we haven’t seen wars for N years. We’re a comfy crowd, and even in World War 2 when we were occupied by Germany, nothing got bombed. So why aren’t our buildings draughty?

The thing that caused Denmark to rethink and redo its energy system, was the oil crises of the 70’s, combined with a government with high focus on the environment, and a public demand for cheaper, safer energy. It’s a 3 point system, the tripod if you will. There must be a need I society, that pressures for action. There must to be a government who is willing to execute elaborate plans. And there must to be a public that voices and influences in which direction the plans should move.

The 70’s oil crises shock the global notion that we will always have enough affordable oil. But let’s compare. Was the US affected by the 70’s oil crisis? Yes, but back then they had a rising oil production, so their outlook was that they could be almost self sufficient. Denmark on the other hand was in trouble. We needed something to free us from the dependence on forging oil (since we had none back then), and fast. And in seeing as the public was not keen on the idea of nuclear power, and voiced it loud and clear, there were two things left to do; find alternative ways of producing heat and electricity, and simply use less heat and electricity. So in other words, the Danes got to work. We build and integrated heat and power plants, exporting the knowledge and technology to other countries. We invested hugely in windpower, paving way for the Danish windpower company Vestas, the leading in its field. We gave subsidies to home improvement, such as double layered windows and insulation, thus enabling regular folks to make the necessary improvements. The demand for insulation also made the Danish company Rockwool, the leading insulation company in the world. When life hands you lemons…

So government investments and subcidies, created leading companies in the field of renewable energy and energy savings.  So now you might say “Oh, but this is obviously the makings of a socialist state”. Well no, the government initiatives came as a response to the public demand for cheaper, safer energy, and of the public discourse that renewable energy was good, and nuclear power was bad. The public had a strong voice rooted in strong, organized, cooperating environmental NGO’s, and if you wanna keep being the elected official, you listen to that public voice, and you give them what they want. Of course by doing so you always risk losing voters that would rather have tax cuts than cheaper energy, so as an elected official, you must have the will to act. It’s common sense really, but 30 years later we forget why or how this change happened. 

So to sum up, in order to achieve change in the energy sector there must be a Need in society, a Government that is up for a lot of policy making, and a public damand for change.
Now, we’re in luck. A need in society will come by itself. We have loads of scarcity crises waiting around the corner. It’s gonna hurt, but at least we will have one of the 3 pillars to push for change. Now all we need is a Government with willpower, and a public with a voice.

Oh, by the way, I was writing notes for this in a draughty NYC apartment in lower Manhattan.

Poop Apocalypse - The importance of thinking bio energy plans through

I’ve mentioned before that meeting a future oil crisis with hurt like a *****. But how can we prevent it, and what are the draw backs of those solutions?

In Denmark, we look fear in the eye, and underestimate it. So when we saw that the North Sea oil was running out, we established a climate commission that would work out how Denmark would become fossil fuel independent by 2050. The short version of the report can be found here, in english. I was fortunate to attend a lecture by one of the 8 people on the committee. Even more fortunate to receive one of his two hard copies of the climate report –I’m just that kind of gal. But back to the point. It is, according to the climate commission’s report, more than possible that Denmark become fossil fuel independent by the year 2050. And there was much rejoicing. However! There are circumstances. Most of the report promotes bio fuels, as the least expensive way to achieve this goal. In short bio fuels are extracted from either crops such as sugar or corn, or from byproducts such as kitchen waste or animal waste. And yes, animal waste is feces and urine. This creates a bio mass, from which bio- ethanol, bio gas and other bio fuels can be extracted.
It is speculated, that if Denmark goes all in on Bio fuels, while the rest of Europe  stand by and watches, we will make a great profit on bio fuels, and will experience the wind turbine adventure part two. But if the rest of Europe follows, we will struggle to produce enough biomass to meet our own needs.

Problem a) The definition of the system.

In the above mentioned, the system only contains Denmark. If we assume that our surroundings won’t act as we do, we will make a huge profit. But can we afford to think like that? When planning for your country’s future supply security, you need to examine the situation holistically, from start to end. You can’t discard the rest of the world. I’m pretty sure they too would like heat, gas, electricity and something to run their cars on.

Problem b) The poop.

Bio fuel is great alternative to both fossil fuel and wind turbines, but we have to fully grasp their impact. Here an example. And yes, this really happened.

Some of my fellow students did a study on a biomass plant in Kenya, where the waste of a public toilet and bath house, was used to produce bio gas. It’s was a 2-for-1 deal. Give the community good toilet and bath facilities, and get an energy source out of it. Yes, human poop and pee is used to make gas. The students visited the plant to investigate and suggest improvements for the biogas facility. The plans for the facility were thought up almost 6 years go. Here’s the great part:

When the facility was planed, built and then 3 years ago taken to use, there was no plan, non what so ever, for how to dispose of the sludge. So in 2010 they had been operating for 3 years and now their tanks were full. No one had thought of what to do with the sludge once the tanks were filled. So now, when they needed to make some space in the tanks, they just kindof… well, emptied them in the Nairobi river. Yes, let that one sit for a bit.
They didn’t foresee the eventual capacity of the tanks. There was no long term plan, and now all the sludge, all that human waste, is going into the Nairobi River. I wonder what else goes into that river? I wonder how many people wash themselves in that river? How could this happen? Is it the illiterate 3rd world countries that are just too dumb to plan and operate such facilities? It must be, right? Guess again. This project is an 1st to 3rd world aid project, like so many others. What whent wrong here, was communication and logistics. It was simply somebody else’s problem.
                                                                                  
Problem c) The resources
         
You might be thinking ‘Why use poop? Why not keep using crops?’
Remember the global food crisis a few years back, when prices on corn and flower sky rocketed, sending millions of people into starvation? One of the main reasons for that was the increased use of crops to produce bio fuel, which expanded the demand for corn and other crops that can be used for bio fuels, which made prices rise.
If you’ve got your pulse on the bio fuel beat you might be saying ‘Well, yes that was the 1st generation bio fuel. Then came the 2nd generation where byproducts from farming was used, and now the 3rd generation of bio fuels, where algae is used instead of crops, is showing great potential’.
I say, right you are. Algae holds a far greater potential energy that crops, without making food prices soar. However. You still need to produce a huge amount of algae if you’re gonna provide fuel for the entire world. The algae has to be farmed, and this takes up a lot of space. The barren desserts in the U.S. have been suggested for mega algae farming facilities, which might look something like this.

But it’s in no way enough to meet energy demands, even if you place such farms in all barren, but accessible, regions of the world. 


Growing up we have all been told, that we should not put all our eggs in one basked. The future energy supply is not an exception. Betting on only one source of energy to sustain the energy need for tomorrow, whether it be wind power, bio fuels, nuclear power or crude oil, will cause more problems than solutions. Holistic thinking, where more than just the nearby system is uncluded, as well as viewing the full life cycle of your energy source including resource availability and disposal of byproducts, is essential for securing energy and other resources. This along with global awareness, combined solutions and good communication will keep us from smashing all our eggs, that we so far still carry in one basket.



Extra note on bio fuels, added January 22: On the 21nd the Los Angeles Times ran this article about how the EPA will now allow for up to 15% ethanol blended in gasoline for cars produced after 2001. This will on one hand shift the power balance a tiny bit, from a crude oil dependent future, to a more sustainable economy, and better yet, en a smooth transition. But it is still important to not view bio fuels as the only way to a renewable energy source. Replacing one addiction with another is not a cure.
