The international aviation industry has failed to meet all but one of 50 of its own climate targets in the past two decades, environment campaigners say.
A report commissioned by the climate charity Possible assessed every target set by the industry since 2000 and found that nearly all had been missed, revised or quietly ignored. The charity says the findings undermine a UK government plan to leave airlines to reduce their emissions through self-regulation.
Leo Murray, Possible’s director of innovation, 说: “This forensic investigation shows just how implausible and credulous the government’s jet-zero strategy is shaping up to be. How can we credibly expect this industry to overdeliver on emissions reduction when they’ve never met any of their previous climate targets?
“It’s clear that we need to demand reduction via a frequent flyer levy, which would discourage the frequent flying by a small group of people which makes up the bulk of emissions from planes.”
Air travel accounted for 2.1% of human-produced carbon dioxide emissions in 2019, equivalent to about 915m tonnes, according to the Air Transport Action Group. It is estimated that 15% of people take 70% of all flights, Possible says.
The air targets report was written by researchers from the sustainability agency Green Gumption, who examined climate targets starting and finishing between 2000 和 2021, and assessed progress against some longer-term goals.
They found that unclear definitions, opaque monitoring and inconsistent reporting made many targets difficult to assess, with many also suddenly changed, replaced or dropped within the study period. 而且, even if the targets had been met, the researchers said, many were insufficiently ambitious to reduce aviation’s climate impact.
在 2007 Virgin Atlantic set a target of a 30% reduction in CO2 per revenue tonne kilometre (一氧化碳2/RTK) 经过 2020, which the company later described as “a big target and we’re sticking with it”, 根据报告. 在一个 2014 sustainability report, with a reduction in CO2/RTK of only 8% from baseline, the airline admitted: “We’re nearly halfway through our target period and know we have to pick up the pace.”
But when Virgin’s 2020 annual report was published, it no longer mentioned the 2020 目标. The following year, a press release from the company announced a new target of 15% gross reduction in CO2/RTK by 2026.
The researchers conclude that climate target setting is in effect a smokescreen for business as usual. Such targets “appear to function principally as a tactic for giving an impression of progress and action to address aviation’s environmental impacts to the public and policymakers, in order to prevent any policy barriers to ongoing growth in the industry”, the report says.
It includes a quote from Steve Ridgway, Virgin’s chief executive in 2007, 谁说: “It is important that the airline industry is being seen to do something.”
The government’s jet-zero strategy is due to be published in July and is expected to defy guidance from the climate change committee that deliberate policies will be needed to manage growth in demand for air travel in order to meet the UK’s net-zero goals.
A Department for Transport spokesperson said: “This report wilfully ignores this government’s historic investment in technology, fuel and market-based measures which will help us reach jet zero by 2050 without the need for further taxes. This includes £180m to accelerate sustainable aviation fuel and £685m to develop zero-carbon and low-emission aircraft technology.”
