Climate change and sustainable
construction
Presented by
Dr Ramhari Poudyal, PhD.,MIET
When you destroy others to build
yourself, you will definitely meet
destruction at the point of success.
Reality of Climate Change
• Climate change has become the enourmous
challenge in the 21st century.
• We have had several challenges such as war,
famine, COVID-19 and others but in the
record of all these, climate change is linked
with all of them.
• We have felt that the global temperature is
increasing due to over exploitation as
illustrated on the next slides.
CLIMATE CHANGE
RELATED INDICATORS OF
NEPAL
Nepal is ranked as one of the most
vulnerable countries to the impacts of
climate change. In Nepal, the loss and
damage resulting from climate change
are unprecedented (MoPE, 2017).
Impacts of climate change are
observed in the form of heavy rainfall,
resulting in floods, frequent and
severe droughts, and heat waves.
Climate change is seen as a crucial
challenge to the socio-economic
prosperity of Nepal.
 With the ongoing impact, extreme
events trend, and commitment made
by Nepal to achieve a low carbon
climate-resilient society, it is of utmost
importance to better understand all
aspects through monitoring, modeling,
analysis, and reporting to decide on
the best course of action.
Paris Agreement
• With the adoption of the Paris Agreement in 2015,
Nepal has raised its climate ambitions to implement
the low carbon climate-resilient development
pathways.
• At the event at the United Nations Framework
Convention on Climate Change (UNFCCC) 26th
Conference of Parties (COP 26) meeting, the
Government of Nepal announced its world-leading
commitment to i) remain cumulatively ‘net zero
carbon’ from 2022-2045 and become carbon negative
after that; ii) halt deforestation and increase forest
cover to 45% by 2030 and iii) ensure all vulnerable
people are protected from climate change by 2030.
Nationally Determined Contributions
(NDCs)
• The Nationally Determined Contributions
(NDCs) are the heart of the Paris agreement,
where countries communicate actions they
will take to reduce their Greenhouse Gas
emissions to reach the goals of the Paris
Agreement.

• “A society grows great when old men plant
trees in whose shade they shall never sit.” —
Greek Proverb Those who plant trees in
deserted and difficult to reach places Give
salvation to their previous and future
generations. (Shiva Purana Uma Samhita 11/7)
construction industry
The construction industry is one of the most
prominent consumers of minerals and natural
resources by its very nature.
The need and significance of sustainability in
construction have become a debated topic due to
the growing concerns over global warming and
the finite nature of resources.
This conventional truth caused increased
pressure on construction firms to reduce their
environmental impact.
Sustainable construction
Sustainable construction is important for
many reasons, including reducing greenhouse
gas emissions, conserving resources, and
improving the long-term durability of our built
environment.
Sustainable architecture includes basic
elements such as energy efficiency and water
usage externally and internally, eco-friendly
materials, and improving air quality.
What are the three main principles of
sustainable construction?
Minimize resource consumption (Conserve)by
effective procurement systems and strategies.
Maximize resource reuse (Reuse)
Use renewable or recyclable resources
(Renew/Recycle/Repurpose.
Some of these methods include:
Limiting the materials used to reduce waste.
Controlling waste management, such as
separating and recycling waste.
Constructing green buildings.
Adaptive reuse projects that transform old
buildings.
Managing construction sites to improve
conservation efforts.

Importance of Sustainable
Construction
• According to the United Nations Environment
Programme (UNEP), “the increased
construction activities and urbanization will
increase waste which will eventually destroy
natural resources and wildlife habitats over
70% of land surface from now up to 2032.”
• the building industry has primarily contributed to
the continuous eradication of our ecosystem,
whereas it accounts for:
• 45% of total CO2 emissions in the UK (27% from
domestic buildings and 18% from non-domestic).
• 72% of household emissions are due to space
heating and the provision of hot water.
• 32% of landfill waste from construction and
demolition of buildings.
• 13% of construction waste is sent directly to the
landfill without being used.

  • 1. Climate change and sustainable construction Presented by Dr Ramhari Poudyal, PhD.,MIET
  • 2. When you destroy others to build yourself, you will definitely meet destruction at the point of success.
  • 3. Reality of Climate Change • Climate change has become the enourmous challenge in the 21st century. • We have had several challenges such as war, famine, COVID-19 and others but in the record of all these, climate change is linked with all of them. • We have felt that the global temperature is increasing due to over exploitation as illustrated on the next slides.
  • 4. CLIMATE CHANGE RELATED INDICATORS OF NEPAL Nepal is ranked as one of the most vulnerable countries to the impacts of climate change. In Nepal, the loss and damage resulting from climate change are unprecedented (MoPE, 2017). Impacts of climate change are observed in the form of heavy rainfall, resulting in floods, frequent and severe droughts, and heat waves. Climate change is seen as a crucial challenge to the socio-economic prosperity of Nepal.  With the ongoing impact, extreme events trend, and commitment made by Nepal to achieve a low carbon climate-resilient society, it is of utmost importance to better understand all aspects through monitoring, modeling, analysis, and reporting to decide on the best course of action.
  • 5. Paris Agreement • With the adoption of the Paris Agreement in 2015, Nepal has raised its climate ambitions to implement the low carbon climate-resilient development pathways. • At the event at the United Nations Framework Convention on Climate Change (UNFCCC) 26th Conference of Parties (COP 26) meeting, the Government of Nepal announced its world-leading commitment to i) remain cumulatively ‘net zero carbon’ from 2022-2045 and become carbon negative after that; ii) halt deforestation and increase forest cover to 45% by 2030 and iii) ensure all vulnerable people are protected from climate change by 2030.
  • 6. Nationally Determined Contributions (NDCs) • The Nationally Determined Contributions (NDCs) are the heart of the Paris agreement, where countries communicate actions they will take to reduce their Greenhouse Gas emissions to reach the goals of the Paris Agreement.
