To help the world reach the Paris Agreement goal of carbon neutrality by 2050, about 60 companies in the aviation sector have committed to raise the share of sustainable aviation fuels in the industry to 10 percent by 2030.

The companies, which involve airlines, airports and those reliant on corporate travel, aim to speed up the adoption of low-carbon alternatives to fossil fuels used to power the world’s airlines.

“Hard-to-abate” sectors — including shipping, aviation and steel — comprise over one quarter of global CO2 emissions.

Reducing the aviation sector’s greenhouse gas emissions is a sustainable challenge for global policymakers.

Sustainable fuels are made from renewable feedstock such as municipal and agricultural wastes. Such fuels have already been used on more than 250,000 commercial flights.

“Progressing the development and commercial deployment of sustainable aviation fuel is crucial to decarbonising the aviation industry,” said Sean Doyle, chairman and chief executive of British Airways, one of the signatories.

“Our announcement today to reach 10 per cent SAF by 2030 emphasises our commitment to the planet and prosperity. Upscaling SAF with a global approach will boost India’s economy,” said Ajay Singh, chairman and chief executive at SpiceJet, an Indian budget airline, which is also one of the signatories.

The move by the 60 companies follows a call to government and oil majors by the International Air Transport Association to redirect their focus and investment to support sustainable aviation fuels.
