protect it from possible fires. If a year after you rented
it and there were no fires, would this mean that you
made additional CO2 absorption or emission
reductions?
It's not clear if there was a fire if you hadn't done
anything. That is, we can draw conclusions only over
long intervals and very probabilistically. By the way,
it is precisely because of the high uncertainty and
volatility that the EU does not count absorption by
forests against greenhouse gas emissions. That is, if
your company is included in the number of regulated
companies, it is impossible to compensate for
emissions by absorption in forests.
Thus, not all forest projects will automatically be
equated with climate projects. Just fence off a piece
of forest and say that everything that has grown there
is a carbon absorption, and you won’t be able to sell
it. If a company is going to reduce its carbon footprint
in this way, then it needs to deal not only with
protection, but also with planting forests.
However, the forest theme still requires further
study. It is possible that the absorbing capacity of
green massifs is greater than we expect.
The absorption coefficients that we have now
were calculated in other climatic conditions. It is
possible that now trees can absorb more CO2,
because its concentration in the atmosphere has
increased.
A high share of nuclear energy, large forest areas,
due to the closure of many industrial enterprises after
the collapse of the USSR, greenhouse gas emissions
into the atmosphere also decreased. However, our
country also found its Achilles heel. It's about
methane. It has already been said above that CO2 is
considered to be the main culprit in global warming.
But at the same time, they forget about methane,
and yet it has a 25–30 times stronger greenhouse
effect. True, it is necessary to take into account the
classification of greenhouse gases into short-lived
and long-lived. And methane lives in the atmosphere
for 12.5 years, while carbon dioxide lives for
centuries and even millennia.
That is why greenhouse emissions are measured
more often not in tons, but in conventional units of
CO2 equivalent, for which such a criterion as the
global warming potential is used. It reflects the
relative increase in atmospheric radiation caused by
an increase in the atmospheric content of a given
greenhouse gas by 1 ton compared to one ton of CO2
over time.
Usually it is 100 years, it is on this interval that
methane exceeds CO2 by 25 times. If we take a
shorter period of time, then the difference can grow
up to 85 times. The methane topic is directly related
to the oil and gas industry. One such example was
given by Mikhail Yulkin. We are talking about
satellite images, which show that the pipe belonging
to Gazprom is “floating”.
From this, a conclusion was drawn about the
anthropogenic nature of methane leakage into the
atmosphere. However, representatives of domestic
mining companies do not consider this method to be
correct, and the release of methane into the
atmosphere is associated with the thawing of
permafrost.
The situation is made even more confusing by the
fact that when assessing methane leakage, a
calculation method is used, rather than direct
observations, when leaks are not measured, but are
actually “assigned” based on the methodology.
But in this case, this, as well as shooting from
satellites, is not the best solution, the general director
of CarbonLab LLC believes. Priority should be given
to point observations, especially since there is now
equipment on the market that allows you to detect
leaks remotely. In this case, it will be possible to
determine with great certainty the origin of methane
in the atmosphere.
Indeed, a large amount of methane is emitted in a
"natural" way, due to the melting of permafrost. But
the quotation marks here are not accidental; in the
final analysis, the main reason is also related to
human activity. However, there is an important caveat
here, it no longer falls on the "carbon balance" of a
company that is engaged in mining in a particular
area.
In general, the issue of reducing methane
emissions at the international level was first raised so
seriously at the conference in Glasgow. It was
decided to reduce methane emissions by 30% by
2030, which will reduce the temperature rise on the
planet by 0.2 degrees by 2050. This document was
signed by representatives of more than 100 countries,
Russia is not among them.
Another way to reduce emissions and achieve
carbon neutrality is to offset the emissions produced
in one sector by reducing them in another. This can
be achieved through investments in renewable
energy, energy efficiency, or other low-carbon clean
technologies. The EU Emissions Trading System
(ETS) is an example of a carbon offset system.
Another example of an initiative to reduce
emissions is the carbon frontier adjustment
mechanism, which will apply carbon prices to
imported goods from countries that are less climate
ambitious. This should prevent companies from
moving production out of the EU to countries with
less stringent greenhouse gas emissions regulations.
