'Heathrow expansion, danger to Paris deal on Climate Change’

Climate change and energy policy expert, Prof. Alice Larkin has kicked against the United Kingdom (UK) plan to expand the popular Heathrow Airport in the capital city of London, citing climate change concerns, reports NaijaAgroNet.

Larkin, who is a professor of Climate Change and Energy Policy at  the Tyndall Centre for Climate Change Research, School of Mechanical, Civil and Aerospace Engineering at the University of Manchester, was reacting to the plan proclaimed Tuesday by UK government.

NaijaAgroNet notes that at a cabinet committee on Tuesday, the government approved plans to build a third runway at Heathrow, thus expanding UK airport capacity. Although, there will be a public consultation on the effects of the expansion before the government makes a final decision as part of a national policy statement on aviation, Professor Larkin urged the government to pay attention to climate change scientists.

She pointed out that in the 2000s, research fed into a heated debate on airport expansion in the UK and based on some of the work, arguments were made against further airport expansion, on the grounds that this would be at odds with climate change commitments.

“Just a few years on, with an additional 180 Giga Tonnes of CO2 accumulating in the atmosphere, global climate change policy objectives have been strengthened, and air travel is still dominated by the privileged few,” she said.

Larkin also lamented that the approval of a third runway at Heathrow that will expand capacity and support further passenger growth, stressing that it would be reasonable then to ask some questions.
“Has there been a new, groundbreaking technical solution to decarbonise the aviation sector? Can an increase in air travel somehow sit comfortably alongside the Paris Agreement’s goals? Did we just get the maths wrong the first time around? Sadly, the answer to all of these questions is a resounding ‘no’” she argued.

As said by her, there have been improvements in aircraft fuel efficiency, which have been incremental, pointing out that alternative fuels continued to be researched, their mainstream global penetration to propel civil aircraft remains decades away and not just for technical reasons.

She emphasised that the only real saving grace from the climate perspective is that growth in UK-related passenger numbers has been lower than previously forecast. This has been partly due to the global economic downturn and also, in-part, due to a constraint on airport expansion. In other words, we’ve been somewhat successful in limiting high levels of CO2 growth from the UK’s international flights by maintaining the existing level of airport capacity.

Larkin posited that all this suggests that climate change science is being overlooked to an even greater extent than it was before, in favour of poorly evidenced arguments in support of expanded airport capacity to increase economic growth.

“What is particularly shocking about this turn of events, is that this is happening just days before the Paris Agreement comes into force.  The unavoidable reality is that the highly constrained carbon budget that is consistent with the Paris Agreement requires all sectors to urgently reduce CO2 emissions and accelerate away from using fossil fuels. Of course some sectors will achieve this sooner than others, but no sector can be excluded.

Technically and operationally, she said, options for decarbonising the aviation sector within a timeframe consistent with the Paris goals remain few and far between, which means that demand-side measures that constrain further growth, and have been constraining growth in the past, must receive much greater attention.

She maintained that policy measures aimed at increasing capacity and supporting further growth in air travel, such as the third runway at Heathrow, are at odds with the Paris Agreement. Such developments risk future stranded assets, and are inconsistent with tackling climate change. Researchers will need to raise their voices to new levels given this week’s decisions.

NaijaAgroNet further notes that the upcoming call from the Environmental Audit Committee for evidence of the impacts of the third runway is a welcome opportunity on the horizon, but the government has to be willing to sit up and pay attention to the evidence of climate change scientists and prove their commitment to the Paris Agreement.
