Recent reports have revealed that the campaign of Democratic Presidential candidate Kamala Harris had eventually spent a huge amount of money on private jets while the intense campaign efforts were going on for the US Presidential Elections. Following which the campaign of Kamala Harris might be huge debt now.
Private jet carbon emission up by 46%, flyers emit 500x more than others, study estimates
A recent study reveals a concerning surge in carbon emissions from private jets, increasing by 46% between 2019 and 2023. Researchers discovered that frequent private jet users could be emitting 500 times more carbon dioxide annually compared to commercial flight passengers.
India's Sustainable Aviation Fuel potential 8-10 Million tonnes by 2040: Deloitte
India could produce 8-10 million tonnes of Sustainable Aviation Fuel (SAF) by 2040, requiring $70-85 billion in investments, according to a Deloitte India report. SAF aims to propel aviation sector decarbonisation, with the potential to reduce carbon emissions by 20-25 million tonnes annually. These initiatives are expected to create 1.1-1.4 million jobs and lower crude oil import bills by $5-7 billion yearly.
What is 'Mission Mausam' and why is it needed?
India's 'Mission Mausam' aims to enhance weather forecasting and management using advanced tools like AI, machine learning, and expanded observation networks. The mission will include cloud chambers, additional radars, satellites, and supercomputers to improve accuracy and tackle challenges posed by climate change.
Australian airports face costly fight against worst climate risk
A new analysis reveals that almost all of Australia's major airports, including Sydney and Brisbane, are highly vulnerable to climate change impacts such as storms, floods, heat waves, and high winds.
ET Startup Awards 2024: Nominees for Best on Campus
The award will showcase a startup whose impact can be judged both by the idea and the execution. The founders should have been students whose aim was to build a commercial enterprise.
Time to retire ¡®hard to abate¡¯ as climate solutions become more affordable
Experts recommend 'affordable to abate' to emphasize that technologies are available for high-emission sectors like steel and cement.
These three overlooked climate challenges are key to a net-zero future
Light industries, such as food and beverage manufacturing, contribute significantly to emissions and need new, effective solutions. Innovation in energy storage is also essential due to increased renewable energy usage.
ET Explains: High temp hits flights to Leh. Why?
IndiGo recently cancelled flights to and from Leh due to high temperatures affecting runway operations, highlighting the challenges of operating in extreme heat and high altitudes.
Hydrogen-powered private jets can cut emissions ¡ª If they can get off the ground
A 2021 report found that some private jets emit two tons of CO2 per hour ¡ª at least five times more pollution per passenger than commercial flights. That¡¯s 50 times worse than trains.
Singapore Airlines tragedy: What is air turbulence? Is it related to climate change? Incident deconstructed
A recent incident of air turbulence involving Singapore International Airlines has raised questions regarding the frequency and nature of winds that challenge the aircraft.
Air turbulence: Here are world's most turbulent routes, airports and countries
A Singapore Airlines flight faced severe turbulence, leading to one death and multiple injuries. Turbulence, unstable air moving unpredictably, includes dangerous clear-air turbulence near jet streams due to wind shear. Turbli tracks turbulent flights like Santiago-Chile to Santa Cruz-Bolivia and Tokyo.
What is in-flight turbulence, and when does it become dangerous for passengers and crew?
A British man's death and numerous injuries on a Singapore Airlines flight due to severe turbulence highlight the dangers of unstable air. While turbulence-related fatalities are rare, injuries are more common, especially among flight attendants. Clear-air turbulence, often near jet streams, is particularly dangerous as it occurs with no visible warning. Climate change may increase turbulence, but airlines have safety measures in place. Experts advise passengers to wear seat belts, the best defense against turbulence-related injuries.
Cleaner skies ahead? A glimmer of hope for airline industry¡¯s clean fuel challenge
A breakthrough emerges as a rural Georgia plant readies to produce the world¡¯s initial commercial supply of cleaner jet fuel, converting ethanol into jet engine-compatible fuel. LanzaJet Inc.'s $200 million facility marks a stride in tackling aviation's climate impact, amidst global efforts. However, scaling remains a challenge, with limited progress due to hefty costs and operational hurdles, highlighting the immense task ahead to meet aviation's emission targets.
A Gates-backed startup is making fuel from water and carbon dioxide
Since its Corpus Christi facility came online in October, Sacramento, California-based Infinium has become one of the first e-fuel makers in the world to turn industrial-scale production from a concept into a reality.
Just how climate-friendly are timber buildings? It¡¯s complicated
The wood components are strong enough to hold up an office tower or apartment block, and building with them is thought to emit much less CO2 than using standard materials.
Decarbonising aviation is vital for climate action as a rising non-Western middle class starts to fly ¡ª COP28 has raised this ambition: Robert J. Miller
Aviation directly contributes 2% to 3% to total greenhouse gas emissions. But it also has non-CO2 effects ¡ª when a plane flies at a certain altitude, it sometimes leaves a persistent contrail, the cloudy line at its back. At times, this forms clouds and traps heat to Earth which can raise the effect to 6%. Now, in 2018, only 11% of the world flew. But a rising middle class across Asia, South America and Africa will be flying soon ¡ª that 2% or 6% sum will increase, Robert J. Miller is Chair in Aerothermal Technology at Cambridge University said.
