The Role of Carbon Technologies in the
"Net Zero" Target

defined objectives with minimal costs (Bui et al., 2018; GCCSI, 2016)2016 has
been characterised by a number of significant successes but also brings into
stark contrast some serious challenges. The Paris Agreement lays a sound
foundation on which the world can build its climate change mitigation actions.
We know that the targets volunteered by countries at the Paris Conference of
Parties (COP.
As of Nov 9, 2021, 18 out of the 123 countries that submitted their
Nationally Determined Contributions (NDCs) include CCUS technologies. On
the same date, 33 out of 44 countries which submitted their Long Term Low
Greenhouse Gas Emission Development Strategy (LTSs) stated that they will
contain CCUS technologies as a mitigation activity. Moreover, the application
details in Article 6 of Paris Rulebook, which was finalized with COP26, have
been completed to a great extent. Article 6.2 on international emission trade
and Article 6.4 on the review of Clean Development Mechanisms (CDM)
accreditation standards and practices and the adoption of new procedures
and methodologies to replace CDM are impartial in terms of technologies.
Thus, it would be fair to suggest that they refer to CCUS technologies. In
addition, in COP26, the decision to “phase-down unabated coal (other fossil
fuels were not covered)“, would make way for CCUS technologies.
This article aims to provide a summary of the contribution of CCUS
technologies in reaching the “net zero“ carbon emission target. First of all,
the remaining carbon budget to keep global temperature increase below
2°C compared to pre-industrial levels is revealed. Next, CCUS technologies
is defined and how they will contribute to the “net zero“ target is explained.
Then, information is provided on the role of CCUS technologies in branches
of industry where emission mitigation is hard. Finally, capacity of current and
future CCUS facilities to remove CO from the atmosphere is mentioned
2
and the role of CCUS technologies in reaching neutral carbon balance is
emphasized.

Global CO Emissions

In order to keep global warming below the desired temperature levels, there
appears to be a fixed amount of carbon that can be released in the World.
This fact is exhibited in detail in Figure 1, prepared by Intergovernmental
Panel on Climate Change (IPCC).
