Mitigation of climate change and aviation.pptx

Reducing aviation's environmental impact demands a multi-pronged approach. Technological advances, sustainable fuels, industry initiatives, and strong policies must work together to lower emissions. While industry-led actions set a foundation, robust regulations and collaborative efforts among airlines, governments, and fuel producers are essential. Without urgent, united action, aviation will remain a substantial climate challenge.

2. Introduction

3. Mitigation strategies Technical innovations New designs, lightweight materials, and hybrid-electric technologies are being developed to improve fuel efficiency. Alternative fuels Sustainable aviation fuels (SAFs) and synthetic fuels offer potential emissions reductions, though production scale is still limited. Policy measures Programs like CORSIA and potential carbon taxes aim to cap or reduce emissions through regulatory and market-based approaches.

5. Lighter Materials Carbon composites, fiber-reinforced polymers. Fuel-Efficient Aircraft These materials reduce the overall weight of aircraft, which directly impacts fuel consumption and reduces Carbon dioxide CO₂ emissions per flight.

6. Improved Engines Efficient turbofans, cleaner combustion. Fuel-Efficient Aircraft Newer turbofan engines are designed with higher bypass ratios, which means more air is pushed around the engine rather than through it. This design reduces fuel burn and emissions Engine manufacturers also focus on 'lean-burn' technology to reduce pollutants like nitrogen oxides (NOx), which contribute to both air quality issues and climate change.

7. Aerodynamic Optimization Winglets, optimized wings. Fuel-Efficient Aircraft Aerodynamics is key to reducing drag and increasing fuel efficiency Modern planes feature winglets—those small upturned tips on the wings—and carefully optimized wing shapes to reduce drag

8. Biofuels for Aviation 03

9. Biofuels challenges Sustainability Issues While biofuels are considered renewable, their environmental impact depends on how and where the feedstocks are produced. Unsustainable farming practices can lead to soil degradation, water pollution. High Production Costs Producing biofuels is still more expensive than refining traditional jet fuel due to complex production processes and limited economies of scale. Limited Supply Global biofuel production is currently low, and aviation competes with other sectors, like road transport, that are also seeking sustainable fuel options. Competition for Agricultural Land The feedstocks for biofuels—such as crops and biomass—require land, water, and resources, potentially competing with food production and conservation efforts.

10. Solutions Scaling Up Sustainable Biofuel Production with Public-Private Partnerships Partnerships between governments, research institutions, and private companies can help bring down production costs and increase supply. Government incentives and subsidies, as well as research funding, can support biofuel production facilities and make these fuels more affordable. Diversifying Fuel Sources with Synthetic Fuels (E-Fuels) E-fuels, produced from renewable electricity, water, and captured CO₂, are a potential alternative that sidesteps many challenges associated with biofuels. They don’t rely on biomass or agricultural land, making them less disruptive to food systems and natural habitats.

11. Conclusion Reducing aviation's environmental impact demands a multi-pronged approach. Technological advances, sustainable fuels, industry initiatives, and strong policies must work together to lower emissions. While industry-led actions set a foundation, robust regulations and collaborative efforts among airlines, governments, and fuel producers are essential. Without urgent, united action, aviation will remain a substantial climate challenge.
