Major US airline Delta has announced it will spend $1 billion over the next decade to achieve carbon neutrality.
The company has announced to reach is aims, it will reduce the amount of jet fuel it uses and increase its efficiency - which will consequently reduce the amount of carbon emissions.
Delta will also invest in carbon removal programs in areas such as conservation and 'seek coalitions' with employees and suppliers to decrease their environmental impact.
'No single solution'
According to the Guardian, Delta's Chief Executive Ed Bastian said: "There’s no challenge we face that is in greater need of innovation than environmental sustainability, and we know there is no single solution.
"We are digging deep into the issues, examining every corner of our business, engaging experts, building coalitions, fostering partnerships and driving innovation."
Last year, Delta announced it had 'replaced 84 aircraft in our fleet with more fuel-efficient models, reduced single-use plastics and energy use, and invested in sustainable jet fuels ' in a bid to 'make travel more sustainable'.
The company also launched a carbon emissions calculator, allowing customers to offset their flight by 'supporting projects that produce measurable benefits to the atmosphere'.
