【推荐1】Sustainability was a hot topic at the Paris Air Show, the world’s largest event for the aviation industry, which faces increasing pressure to reduce the climate-changing greenhouse gases that aircraft emit. Even the massive orders at the show got an emission-reduction perspective: Airlines and producers said the new planes would be more fuel-efficient than the ones they replaced. However, most of those planes will burn conventional kerosene-based jet fuel.

Some companies are working on electric-powered aircraft, which are seen as a way to reduce the environmental effects of the aviation industry, providing zero emissions and quieter flights. However, they are still some way off from widespread commercial use. That means sustainable aviation fuel (SAF) has become the industry’s best hope of achieving its promise of net zero emissions by 2050. SAF, however, accounts for just 0.1% of all jet fuel. Made from sources like used cooking oil and plant waste, SAF can be mixed with conventional jet fuel but costs much more.

With such a limited supply of SAF, critics say airlines are making overly ambitious promises and exaggerating how quickly they can ramp up the use of SAF. The industry even has skeptics: Nearly one-third of aviation sustainability officers in a GE Aerospace survey doubt whether the industry will hit its net zero goal by 2050.

Across the Atlantic, a consumer group called BEUC filed a complaint against the European Union’s executive arm, accusing 17 airlines of greenwashing. The group says airlines are misleading consumers and breaking rules on commercial practices by encouraging customers to pay extra to help finance the development of SAF and offset future carbon emissions created by flying. In one case, the group’s researchers found Air France charging up to 138 euros for the green option.

“SAF is indeed the biggest technological potential to decarbonize the aviation sector, but the main problem is that it isn’t available. We know that before the end of the next decade — at least — it won’t be available in massive quantities,” said Dimitri Vergnc, a senior policy officer at BEUC.

Eleven-year-old Xavier Baquero-Iglesias was playing with a friend on Astroturf in Naples, Florida when he noticed the field was super hot. It was much hotter than real grass. Xavier formed a hypothesis(假说) about why this was so. Then he invented SoleX Turf. It uses the heat from Astroturf to make electricity. Now 12, Xavier says his invention creates electricity in a way that is less harmful to the environment.

Jeremy Muchilwa, 13, and Michelle Muchilwa, 15, are siblings from Kisumu, Kenya. They once participated in the Ocean Heroes Bootcamp. They were inspired to fight plastic pollution. So they created a campaign whose goal was to pick up plastic waste in nearby Lake Victoria. The Muchilwas want to find new ways to draw attention to plastic waste.
