Emissions of greenhouse gases (GHG) have become a huge
problem worldwide. The global temperature is expected to increase over the next
century with potentially devastating consequences. As a part of the Climate and
Energy Package the EU decided on the 20-20-20 goal by 2020 with the intention
of limiting the global warming to two degrees Celsius by 2050. 20-20-20 refers
to a 20 % reduction in GHG emissions, 20 % improvement in energy efficiency, and 20 % use of
renewable energy in the EU. In order for this goal to be achieved, Norway set a
national target of 67.5 % renewable energy [1]. Figure 1 shows how the GHG
emissions are distributed within different sectors in EU and Norway. It is
obvious that Norway is in a different situation than the rest of Europe, which
will be reflected in the way the country plans to reduce its GHG emissions
compared to in the EU.

Emission reductions
Norway has already a high renewable share in its
energy mix, and improving its energy efficiency by 20 % is a sensible and could be possible to
implement. Reducing the GHG emission by 20 % may have different implication for
Norway compared to elsewhere in the EU. Many European countries rely on resources such as
coal and natural gas for their electricity generation. The CO2
emissions from these power plants are considerable, and stand for about 31 % of
the total emissions in the EU (Figure 1). A quick comparison reveals
that this is not the case in Norway where about 97 % of the electricity is
produced through hydropower and the
majority of the GHG emission originates from industry, transport and petroleum.
The difference between
Norway and EU when it comes to CO2 emission indicates that different
paths should be taken if the emission reduction targets are to meet. The
International Energy Agency (IEA) , based on the Times model, has estimated the
amount of sector-wise GHG reduction possible to achieve for the so called two and four degree (2DS and
4DS) global temperature increase scenarios.
This work can be found in
reports given by the Nordic Energy Technological Perspective (NETP) and Energy
Technology Perspective (ETP) [5,6]. Among the many interesting points in these reports is that while many European
countries show potential for large GHG reduction within the energy sector, the main reduction in Norway,should mainly
come from industry and transport sectors.
These sectors are the one the country has chosen to focus on.
The relative emission
reductions possible to achieve in Norway and the EU in the transport and
industry sectors can be seen in Figure 2 [4,5]. Here, the 4DS has been chosen as a
reference case. The reduction shown is relative both with respect to the
sectors and senarios. Note that reduction predicted to happen in the transport
and industry sectors in Norway amounts almost to 100% of the estimated reduction
over the coming 50 years.
In EU the two sectors
represent less than 60% of the estimated total emission reduction and
significant reductions is expected to come from the power sector.

and the 4DS scenarios in EU and Norway. Adapted from [5].
The NETP report points out
that, the industry sector will realize the greatest emission reductions the
first 10 – 15 years. It is suggested that this can be realized through improving
the efficiency, investing in new production technologies, shifting from fossil fuels
to e.g. biomass, by carbon capture and storage and by improving recycling of waste
material [6].
According to the NETP
scenario the reductions in the transport sector will mostly occur after 2020.
The mitigation to reduce GHG emission within the transport sector are primarily
related to reducing usage of fossil fuels, efficiency increase, and modal shift
to public transport [4, 6]. This can for instance be possible to achieve, by introducing biofules
and electrifying the transport fleet.
In NETP the 2DS points to a
20 % shift from private to public transportion system. More details on the
specific mitigations required to reach this goal can be found in Klimakur 2020 [4]
and can be summarized as infrastructural investments in the public transport
sector together with increased toll-road fees in large cities and reducing the price for public transportation.
Our suggestions
In order for Norway to
contribute to limit global warming to only two degrees, we suggest first and
foremost more offensive policies should target the industry and the transport
sector, since the largest emission cuts
can be only come from these sectors. To reach the goals presented by the ETP
and NETP reports for the transport sector, more attention should be given to biofuels,
public transportation and electrification of transportation. This will not only
be beneficial for the global environment, but will also benefit the local
communities through better air quality and less pollution.
Policies should also target
the industry sector. The industry sector in Norway is subject to strong
competition from low cost countries and strict policy regulations for emission can
easily cause some businesses to close down or flag out. Policies targeting emission
reduction from this sector should, if possible, be subsidized. It does not help
the global environment to move industry to countries with less strict regulations.
Since the NETP shows that industry has the most reduction potential in the
first 10 to 15 years, industry should also be the first priority for emission
reduction policies.

The only word that I can use here is complete. I am delighted to receive well defined information all under one roof. Now I am ready to book greenhouse or my choice and will not make any sort of delay as well. Plus I also request others to have a loom too.
