Green Talk – Let’s Change Before It’s Too Late (Essential Notes)

KKTM & TVET Programs

• KKTM Petaling Jaya offers Diploma in Electronic Engineering (Internet of Things – IoT)

  • Duration: 2.5 years   • Intakes: April & Sept

  • Tagline: “IoT Drives Innovation” – hands-on, weekly lab hours

• TVET MARA network: KKTM, MJII & IKM across Malaysia

  • Aim: produce competent, industry-ready graduates in green & smart technologies

MARA Green KPI & Policy (since 2018)

• Annual KPIs for every KKTM/MJII/IKM

  • Energy & water saving targets

  • Shift to renewables: solar, rainwater harvesting, wind-water

  • $\ge30\%$ campus land as green area

  • Continuous green awareness activities

• Alignment with SDG 2030 & UNESCO Greening TVET agenda

Global Warming Overview

• Definition: persistent rise in Earth’s average temperature due to trapped heat (greenhouse effect)

• Critical limits: $+1.5^{\circ}C$ already approached; $+2^{\circ}C$ is upper safety threshold

• Projection: uncontrolled emissions could reach $+4^{\circ}C$ by $2100$

Greenhouse Gases & Major Sources

• Gases: $\text{CO}<em>2$, $\text{CH}</em>4$, $\text{N}_2\text{O}$, CFC/HFC

• Primary sources

  • Fossil-fuel combustion (coal 45 %, natural gas, oil) – power & industry

  • Transportation (road, air)   • Agriculture & livestock (methane)

  • Deforestation • Population & consumption growth

Impacts of Climate Change

• Ice-sheet melt ➔ sea-level rise (est. $\sim80\,\text{ft}$ if Antarctica melts)

• Extreme weather: heatwaves, droughts, intense rain, floods, storms

• Ocean effects: higher temperature, acidification, habitat loss

• Malaysian context

  • CO₂ emissions rose $\approx2\times$ (2000-2015)

  • Energy sector largest share; per-capita emissions high vs GDP

  • Coastal regions at risk of inundation

Carbon Footprint Types

1. Embodied Carbon – emissions from material extraction ➜ manufacturing ➜ transport ➜ construction ➜ disposal

2. Operational Carbon – emissions during use (e.g. electricity)

   • Malaysia emission factor $0.646\,\text{kg CO}_2/\text{kWh}$ (coal-heavy grid)

3. Carbon Sequestration – biological/physical capture & storage of $\text{CO}_2$ (trees, CCS technology)

4. Carbon Offset – purchasing credits that fund renewable or conservation projects to balance residual emissions

Mitigation Strategies

Individual / Home

• Switch off idle appliances; use $\ge$ 2-star (prefer $5$) energy-efficient devices

• Opt for solar PV, natural drying, minimal air-conditioner use

• Reduce single-use plastics; practise 3R; buy local products

• Eat less red meat; grow trees/gardens

Transport

• Car-pool, public transport, cycling, walking

• Prefer hybrid/electric vehicles; limit air travel or purchase carbon offsets

Institutional / Campus

• Conduct energy audits; integrate IoT for smart control (remote lighting & HVAC)

• Specify regional & recycled building materials; adopt Green Building standards

• Invest in solar, biomass, wind; explore biodesel/hydrogen R&D

• Embed sustainability modules (e.g. Green Building course at KKTM Sri Gading)

Key Numbers & Figures (Quick Recall)

• $+1.5^{\circ}C$ current warming • $+2^{\circ}C$ danger line • $+4^{\circ}C$ possible by $2100$

• $0.646\,\text{kg CO}_2/\text{kWh}$ – Malaysian grid factor

• Power generation mix (2015): coal $45\%$, natural gas $45\%$, renewables <10\%

• Campus green area target: $\ge30\%$ of land

• Diploma IoT KKTM PJ: 2.5 years, intakes April & Sept

Remember: “The greatest threat to our planet is the belief that someone else will save it.”
