PROJECT INFORMATION
Salient features of the Proposed NAMA
Sector
: Industry
Technology
: Energy Efficiency
Type of action : National/Sectoral goal
GHGs covered by the action: CO2
Expected timeframe for the preparation : 4 years
Implementing entity : Ministry of Environment, Green Development and
Tourism
Total estimated cost of implementation : €15 million
Required support for the implementaion of the action : €15 million
• Cement production emitting approximately 1 ton of CO2 per ton of cement
on average (in Mongolia 1.2 tCO2e), responsible for 5-10% of total
emissions globally.
• Cement production shares 25% of total coal consumption in Mongolia.
NAMA DESCRIPTION & EXPECTED OUTPUTS
NAMA Description
• The objective of the proposed NAMA is to initiate the transformation of
Mongolia’s construction sector towards a less carbon intensive
development path through the introduction of supplementary
cementitious materials (SCM) that can replace up to 70% of cement in
concrete.
• The proposed NAMA is a very innovative approach because it will
introduce an environmentally sound alternative to Portland cement, thus
leading to transform the building materials sector. Moreover, the project
will recycle fly ash from local coal-fired power plants as raw material.
• The NAMA project aims at establishing a 350,000 t/y supplementary
cementitious materials /SCM/ production facility, the design of supportive
policies and management of the standardization process. The project will
recycle fly ash from local coal-fired power plants as raw material. The
NAMA is expected to result in some 420,000 tCO2 emissions reductions
annually.
RELEVANCY OF THE NAMA IN THE NATIONAL POLICY CONTEXT
National Action Programme on Climate Change (NAPCC) and the programme was
approved by the State Great Khural (Parliament) in 2000 and updated in 2011.
• The action programme includes the national policy and strategy to tackle the
adverse impacts of climate change and to mitigate greenhouse gas emissions.
• NAPCC is aimed not only at meeting the UNFCCC obligations, but also at setting
priorities for action and to integrate climate change concerns into other national
and sectoral development plans and programmes.
FINANCING
Mongolia is seeking various opportunities for financing NAMA related actions,
including bilateral and multilateral financial resources including ODA and soft
loan. Also, in order to scale up the level of finance and facilitate transfer of
technologies, finances through mechanisms such as the NAMA Facility, ADB, KFW
and other innovative means of finance are also expected .

Environmental benefits:
The project uses either fly ash recycled from coal-fired power plants or very abundant natural
resources (volcanic ash) as raw material, while Portland Cement (PC) production consumes
the depleting natural reserves of limestone;
The project reduces coal-based energy consumption by 90% and reduce water demand in
concrete by 40% compared to PC-based concrete;
Avoided harmful emissions of mercury and particulate matters associated with coal
consumption can contribute to reduce atmospheric pollution.
Performance benefits:
SCM delivers stronger and longer-lasting concrete;
SCM concrete improves mitigation of alkali-silica reactivity, reduces heat of hydration,
reduces concrete permeability, improves protection from chloride and sulphate attacks;
SCM concrete road paving significantly increase paving productivity and road surface
durability as well as reduce petrol consumption by about 5%;
By extending the life of structures, SCM concrete extends their replacement cycle while at
the same time reducing maintenance costs.
Economic benefits:
The total cost of the SCM plant construction is ten times less than PC plant;
Replacement of energy intensive PC process with mechanically activated SCM means low
operational and maintenance costs;
Superior return on investment due to a combination of lower CAPEX and OPEX.
