Airlines Are Encouraging Passengers to Offset Emissions Generated by Their Flights by Offering Programs for Travelers to Pay an Extra Amount.
Gol, Tam, and United already offer this payment option through the company’s website. According to Gol, flight pollution offset from June 2021 to December 2022 was 13,100 tons of CO2, through payments made by customers and other actions. The effort is equivalent to the preservation of 1.8 million trees.
The calculation of these values is based on mathematical models that allow for an accurate estimate of how much pollution is generated per flight, taking into account consumption at each stage of the trip. For this, the variable prices in the carbon credit market are also considered: typically, offsetting a ton of CO2 costs between US$ 10 and US$ 20 (approximately R$ 52 and R$ 104).
Air France-KLM has allowed passengers to pay for flight pollution offset since 2021; at Gol, a feature was launched on the website for customers to pay for the offset at the time of purchasing the ticket.

As the South of Brazil prepared for the most intense polar air of 2026, a gale with winds over 60 km/h destroyed 200 homes in Ponta Grossa and cut power to 7 neighborhoods in Porto Rico in the wake of storms across Paraná.

As Europe seeks alternatives to Russian gas and saturated solar energy, IDOM connects to the Spanish power grid a 42-meter vertical cylinder equivalent to 14 floors that generates 30 kW of electricity solely from the movement of the waves in the Cantabrian Sea.

While the global nuclear sector is dominated by Westinghouse, Rosatom, KEPCO, and EDF, the Argentine state-owned company Nucleoeléctrica approves a change in its statute to sell technical services in the international market and position itself as an exporter of nuclear know-how accumulated over 5 decades.

While conventional electronic memories fail in low orbit after 30,000 rads, researchers from Georgia Tech have presented a ferroelectric NAND flash memory that remains stable up to 1 million rads, equivalent to 100 million consecutive X-rays.
The aviation sector faces a challenge in reducing its carbon dioxide emissions. In 2019, before the pandemic, 17.4 thousand tons of CO2 were emitted in Brazil (1.25% of the country’s total). In 2021, with fewer flights operating, this number fell to 10.9 thousand (0.71%).
To mitigate the situation, 115 countries signed the Corsia agreement (Carbon Offsetting and Reduction Scheme for International Aviation) which provides for mandatory measures starting in 2027. Among the main strategies are the development of new technologies for aircraft, improvement of air traffic and airport operations, use of less polluting fuels, and carbon offsetting.
Some airlines already offer passengers the option to donate money to increase the purchase of SAF (sustainable aviation fuel), which is still scarce in the market. Although it is a welcome solution for airlines, which are looking to pay off debts generated by the pandemic halt and recover pre-pandemic travel volumes, some question whether this responsibility should not rest with them.
