What is carbon?

This question and answer is part of the Guardian's ultimate climate change FAQ

See all questions and answers
Read about the project

Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table.

Carbon is a very abundant element. It exists in pure or nearly pure forms – such as diamonds and graphite – but can also combine with other elements to form molecules. These carbon-based molecules are the basic building blocks of humans, animals, plants, trees and soils. Some greenhouse gases, such as CO2 and methane, also consist of carbon-based molecules, as do fossil fuels, which are largely made up of hydrocarbons (molecules consisting of hydrogen and carbon).

In the context of climate change, 'carbon' is commonly used as a shorthand for carbon dioxide, the most important greenhouse gas released by humans. Technically, however, this isn't accurate. Carbon only becomes carbon dioxide when each atom of carbon joins with two atoms of oxygen (hence the chemical formula of carbon dioxide, CO2).

This shorthand can sometimes cause confusion, because although 'a tonne of carbon' will often be used to mean 'a tonne of CO2', in a scientific context the same phrase could mean 'CO2 containing a tonne of carbon' (which is a much smaller amount, as oxygen accounts for most of the weight of each CO2 molecule).

The term carbon also crops up in the phrase carbon footprint, which describes the total amount of greenhouse gases released as the result of a given activity. In this context, 'a tonne of carbon' may mean something else still: 'a mix of greenhouse gases with a combined warming impact equivalent to that of a tonne of CO2'.

Carbon molecules move around the Earth system in the carbon cycle.

EU urged to overhaul fishing policy

Unprecedented alliance of retailers and conservationists urges drastic reform to prevent fish stocks from passing point of no return

Europe's fishing practices must be drastically reformed in order to prevent dwindling fish stocks passing the point of no return, a coalition of British supermarkets and conservationists warned today.

The unprecedented alliance, which includes Sainsbury's, Marks & Spencer, members of the UK's Food and Drink Federation and WWF, is making the strongest statement from business to date on the failures of the European Union fishing policy.

It follows public anger at the practice of discarding fish that was highlighted in Channel 4's Fish Fight series, which has prompted hundreds of thousands of people to sign a petition calling for reform.

Fishermen should no longer be forced to discard large amounts of their catch, as they do under the current system of EU fishing quotas, the coalition said, and the quotas should be reviewed so that stocks can recover.

Discarding is a long-standing and wasteful practice, resulting in as much as two-thirds of the fish caught being thrown back in the water, usually dead. About 1m tonnes are estimated to be thrown back each year in the North Sea alone. Discarding is a consequence of the strict quotas on the amount of fish that boats may land – when fishermen exceed their quota, or catch species of fish for which they do not have a quota, they must discard the excess.

The coalition is putting forward their proposals for a reformed common fisheries policy in a meeting with Maria Damanaki, the EU commissioner for fisheries, in London today.

The commission is in the process of reviewing the CFP, with a view to introducing reforms in two years. The EU is the world's fourth biggest producer of fish, both wild and farmed.

The coalition criticised the practice of discarding as 'the result of poor management and fishing practices that are not attuned to market and consumer needs', and said the CFP was not working.

The group, led by the green campaigning organisation WWF, said that fishermen would be better served by a different system, as the wasteful practice of discarding was a cost to fishing fleets.

Alternatives to discarding include allowing fishermen to land all the fish they catch, but restricting the days on which they are allowed to fish. Better technology can also help to ensure that fishermen are able to target particular species more closely.

The group called on governments to introduce long-term fishery management plans that would include fishermen, giving fleets a bigger role in 'co-managing' stocks rather than simply being handed quotas, as under the current system.

'The Matrix 4' and '5': Are the Rumors True?

Filed under: , ,
Even though this may well turn out to be just another cleverly orchestrated Keanu Reeves meme, the Internet is abuzz today with reports that the actor revealed to a group of London students that two more installments in 'The Matrix' franchise may be on the way -- in 3D, no less.



Now, before you start annoying all your friends by whipping out that lame 'There is no spoon' quote again, consider that the original source -- an anonymous Ain't It Cool News reader going by 'El-Nino' -- is questionable to the extreme and that Entertainment Weekly has already debunked the news. Still, we have to wonder if there isn't something to the rumors, given that the 'Matrix' franchise raked in more than $1.5 billion.



But after the debacles that were 2003's 'The Matrix Reloaded' and 'The Matrix Revolutions,' the two disjointed follow-ups to the truly groundbreaking 1999 original, the biggest question may be whether Reeves and the Wachowski brothers should expect anyone to care.



So, what do you think of this very intriguing and probably not true development? While you're contemplating, check our our pick for the best moment from 'The Matrix' trilogy below, and if you dare, click here to feast your eyes on the worst.

Renewable Energy and Cleantech Mutual Funds and ETFs: Does Tax Efficiency Matter?

Alternative Energy and Climate Change Mutual Funds, Part VI



Tom Konrad CFA



My recent article, In
Clean
Energy,
Active
Management
Pays
, started a bit of a
controversy. Rafael Coven, the Index Manager for The Cleantech
Index (^CTIUS), which is the index behind the Powershares
Cleantech Portfolio (PZD)
, left
a
comment
on
Barrons
and sent me an email saying, 'Your
comparison of funds and ETFs ignores the tax efficiency differences
which are very significant
.'



Rafael is right that it's important for many investors to consider
taxes before making an investment decision, and that ETFs
are
often
more
tax
efficient
than
mutual funds
. But are the
differences in the particular case of clean energy funds really "very
significant"? I had my doubts, so I decided to look at the
numbers and find out.



Why ETFs are Usually More Tax Efficient



ETFs are generally considered more tax efficient because they make
fewer capital gains distributions. A mutual fund or ETF that
sells a position at a profit is required by law to return a prorata
share of any net capital gains to the fund's investors every
year. Positions held less than a year produce short term capital
gains, while positions held more than a year produce long term capital
gains. When these gains are returned to investors, they are
taxable as short or long term capital gains, regardless of whether the
funds are reinvested.



In general, actively managed mutual funds trade much more often than
ETFs, which passively track an index. While many mutual funds
trade much of their portfolio once or more a year, most ETFs only
trade a tiny fraction of their portfolio in order to keep up with
changes in the underlying index.



Hence a mutual fund with a Turnover Ratio of 100% (meaning that, on
average, 100% of the funds holdings are traded each year) will, on
average, only hold a position for a year, and will distribute the
majority of capital gains to shareholders every year, much of which
will be in the form of short term capital gains, which are typically
taxed at a higher rate than long term capital gains. In
contrast, an ETF with a Turnover Ratio of 10% will, on average, hold a
position for ten years. This allows time for significant
undistributed capital gains to build up, and when those capital gains
are distributed, they almost always come in the form of long term
capital gains, which are usually taxed at a lower rate.



Who Needs to Worry About Tax
Efficiency, and Who Doesn't




Not all investors need be concerned about the tax
efficiency. Most obviously, investors who are investing in
a non-taxable account, such as an IRA and a 401(k). Tax exempt
institutions, such as charities, also need not worry about tax
efficiency. Finally, people in lower tax brackets need be less
concerned than those with high incomes, since the taxes on capital
gains distributions will be lower for them.



Undistributed Gains



Most renewable energy stocks are down significantly over the last three
years (roughly the same period as the track record of most of the
ETFs.) This means that, at least in the short term, many mutual
funds and ETFs will not have any capital gains distributions no matter
how well they perform, because previous year's capital losses will be
available to offset future gains. (While funds are required to
distribute realized capital gains, they have no way of distributing
realized capital losses, except for offsetting future gains.)



The Numbers



Morningstar has data on most fund's tax efficiency, including
adjusted returns assuming distributions are taxable, and potential
capital gains exposure (undistributed capital gains as a percentage of
net assets.) The following two tables and charts compare the ETF
and mutual fund three year returns on both tax adjusted and unadjusted
basis, along with potential capital gains exposure and fund
turnovers. Where possible, I used no-load mutual fund shares
because I feel they are more comparable to ETFs than load shares,
despite the fact that long term mutual fund buyers should generally
prefer load shares because of their lower annual expense ratios.

etf tax chart.png


mutual fund tax chart.png



As you can see from the tables, the ETFs have indeed been more
tax-efficient than the mutual funds, but the differences are so
marginal that they are difficult to detect in the charts.



More striking are the extremely large negative
capital gains exposures of many mutual funds and ETFs. The DWS
Climate
Change
Fund
(WRMSX)
, Guinness
Atkinson Alternative Energy Fund (GAAEX),
Van
Eck
Global Alternative Energy Fund (GEX)
, and the PowerShares
Clean
Energy (PBW)
all have undistributed capital losses equal to
multiples of the funds' current values (260%, 241%, 234%, and
198%).
That means that all the holdings in each fund's portfolio could be sold
for three or more times their current value and the funds would still
not have
to distribute any capital gains. Tax efficiency will remain
a moot point for years to come, at least for these four funds, as well
as for the PowerShares
Global
Clean Energy Portfolio (PBD)
and the Calvert
Global Alternative Energy Fund (CGACX)
.



The only fund for which I can really call tax efficiency a concern is
the Gabelli
SRI
Green Fund (SRICX)
. Why does the Gabelli fund stand out
as having a "problem" with tax efficiency? Because the Gabelli
fund
actually managed to turn a decent profit over the last three
years, while their clean energy mutual fund and especially ETF rivals
lost money hand
over fist
. I recently interviewed
John
Segrich, CFA, the lead fund manager at the Gabelli SRI Green fund
,
and he explained in part how they did it.



When it's a sign you're making money, tax inefficiency seems like a
good "problem" to have.



Turnover



It's also worth noting the fairly high Turnover ratios of all of the
ETFs, ranging from 30% to over 60%. That means that, on average,
the
holdings of Clean energy ETFs trade once every 2-3 years, which is not
enough time to build up substantial unrealized capital gains, although
the majority of capital gains distributions are likely to be in the
form of long term capital gains. In fact, the New
Alternatives
FD Inc (NALFX)
has a lower turnover ratio than all but
one of the clean energy ETFs.



Even when we return to an environment where most of these funds are
habitually making gains, and the negative capital gains exposures of
many of the funds are exhausted, these ETFs will have less of an
advantage in tax efficiency over the clean energy mutual funds than
broad market ETFs have over their peers, unless the ETF turnover ratios
fall faster than those of the mutual funds.



Conclusion



While Clean
Energy
ETFs
are a little bit more tax efficient than Clean
Energy
Mutual Funds
, the difference is not currently significant.
Clean
Energy is a very young sector with high volatility and quickly changing
industry structure. The changeable nature of the clean energy
landscape means that a lot of the usual rules do not apply. Not
only do active
managers
have a significant advantage over passively managed funds like
ETFs
, but passive clean energy funds also have much less
significant
tax advantages than passive broad market funds.

Solar Tracer at the Penny Stock Arcade

Dana Blankenhorn



Look up Solar Tracer Corp. on Google and you'll be asked if you
really mean “solar tracker,” which sends you to a company called Opel Solar (OPL.V),
which makes solar concentrators.


Sometimes you should listen to your Google.


But I wanted to learn about Solar Tracer, which says it was bought this weekend by Sector 10 (SECI.OB), a
failing maker of emergency
response equipment
.


That last is not hyperbole – Sector 10 hasn't brought in any revenue
for over a year. It's a stock market trick old as
time, a shell buying an operating company so the latter can go public
at low cost.


But why? Why would Solar Tracer want to go public sub rosa? (Full
disclosure. I own no penny stocks. I did have some AIG once, before
that went into penny territory. I bought in at $60. If you are looking
for investment advice, move along.)


Turns out Solar Tracer is run by the Tedrow brothers of Florida. CEO
Christian is a writer, CFO Tyler a venture capitalist. The two have
been working on a thriller called the Judgement
Trilogy
– they write under the name Thomas
Tedrow
.


Tyler is managing partner
of HART Capital
Management
in Orlando, which describes itself as “a new kind of
venture capital firm.” Among its listed investments is ChinaPharmaHub,
for which Christian (left) sits on the business
advisory board
. ChinaPharma says it is interested in identifying
and bringing to market interesting drugs from China.


Now that you know something about the management, what would you be
buying, if you were interested in buying into this? Mainly Eugene
Augustin
, an expert on microwave
antennas
last seen in July selling his solar antenna expertise to Lady Bug Resource Group,
a Kirkland, Washington based outfit that apparently held the URL
Newsolartec as a subsidiary. Christian Tedrow was listed as the owner
of that URL until last week, when it expired.


After buying Augustin's expertise, in November, LadyBug named a
Thomas F. Krucker its new CEO. Krucker is a former Toyota executive.
Inside of a month Krucker bought MAG International, which said it was developing electric off-road vehicles (its Web site was
recently disabled.


So what's going on?


Near as I can determine the Tedrows needed a new vehicle after
LadyBug flew away. That's what Sector 10 is, a company that owns what
was NewSolarTec but is now called Solar Tracer.


Back when the LadyBug deal got done, Solar Thermal Magazine ran a piece on the Tedrows, and New Solar. In
that piece Christian Tedrow described the Solar Tracer as a solar concentrator that can heat water into
steam for generating electricity.


There's nothing new here. Solar concentrators are old tech. There
are breakthroughs going on here but little evidence Mr. Augustin has
one.


Still, shares in Sector 10 doubled in value, to 1.8 cents per share , on the day after the
Tedrow news broke. OTC Picks featured the company
without knowing they were out of the emergency response business. Their
story paints the company as an emergency preparedness play.


I'm guessing this is another ride on the penny stock arcade that's
going to end in tears.


But it would be so much fun to be proven wrong.
