2. Important words
to understand…
• Climate Change
• Greenhouse effect
• Sustainable/Renewable Energy
• Net-zero transition

3. What is climate
change?
• Climate change refers to long-term shifts in
temperatures and weather patterns. These shifts may
be natural, but since the 1800s, human activities have
been the main driver of climate change, primarily due
to the burning of fossil fuels (like coal, oil and gas),
which produces heat-trapping gases.

4. What is Greenhouse effect?
• The greenhouse effect is a good thing. It warms the planet to
its comfortable average of 59 degrees Fahrenheit (15 degrees
Celsius) and keeps life on earth, well, livable. Without it the
world would be a frozen, uninhabitable place, more like Mars.
The problem is, human activities like burning of fossil fuels for
energy and others are artificially amping up the natural
greenhouse effect. The result? An increase in global
warming that is altering the planet’s climate systems in
countless ways.
• The greenhouse effect is the natural warming of the earth that
happens when gases in the atmosphere trap heat from the sun
that would otherwise escape into space.

5. What causes
Greenhouse effect?
• While 30 percent of the solar energy that
reaches our world is reflected back to space,
approximately 70 percent passes through the
atmosphere to the earth’s surface, where it is
absorbed by the land, oceans, and atmosphere,
to heat up the planet moderately. This heat is
then radiated back up in the form of invisible
infrared light. While some of this infrared light
continues out into space, the vast majority—
indeed, some 90 percent—gets absorbed by
atmospheric gases, known as greenhouse
gases, and redirected back toward the earth,
causing further warming above required level.

6. Greenhouse gasses/ contribution % to total
emission

7. What is
sustainable
energy?
• Energy is sustainable if it "meets the needs of the present
without compromising the ability of future generations to meet
their own needs". Most definitions of sustainable
energy/renewable energy include considerations of
environmental aspects such as greenhouse gas emissions and
social and economic aspects such as energy poverty.

8. Types of sustainable
energy sources
There are 5 main types of sustainable
energy: biomass, hydropower,
geothermal, wind, and solar

9. How can clean energy be adopted to
reduce the impact of climate change
• Clean energy sources are climate change mitigants,
because renewable energy sources such as biomass,
hydropower, geothermal, wind, and solar don't emit carbon
dioxide and other greenhouse gases that contribute to global
warming.
• Replacing fossil fuel sources of energy like coal, diesel, petrol
etc reduces greenhouse gasses, creating a more friendly
atmosphere in the world.
• Appropriate introduction of Energy efficiency in energy usage
pattern and energy efficient appliances/equipment in
organizations will not only help in reducing energy cost but also
the carbon footprints.
• Renewable power could cover up to four-fifths of global
electricity supply by 2050 – drastically reducing carbon
emissions and helping to mitigate climate change.

10. Opportunities available for clean energy
Innovations
• Grant funding from
Developmental/Impact
organizations both locally and
internationally.
• Commercial value potential
for innovative products that
can support climate change
mitigations.
• Awards and Industrial prizes

11. The Global Net-Zero
mandate…
• The concept of net zero greenhouse gas emissions was first
popularised by … the Paris Agreement, a landmark deal that
was agreed at the United Nations Climate Change Conference
(COP21) to limit the impact of greenhouse gas emissions.
• The term net-zero refers to the target of reducing the
greenhouse gas emissions that cause global warming to
zero by balancing the amount released into the atmosphere
from sources with the amount removed and stored by
carbon sinks. This is also described as 'carbon neutrality' and
sometimes 'climate neutrality’. This will mitigate climate change
and possibly starts reversal process of earlier damage done.
• All sectors of our economy must begin to align with this drive
to make the world a better place for all of us.

12. How can youths develop
innovations that supports
netzero transitioning?
• Understanding netzero goals and objectives
• Creative products and innovations that can be utilized
in the clean energy industry across the value chain.
• Research
