Carbon emissions

Overview

Carbon Emissions 

Aviation accounts for 2 percent of man-made global carbon emissions, and with global demand for passenger and cargo traffic forecasted to increase, it is predicted to grow to 3 percent by 2050, according to the UN’s Intergovernmental Panel on Climate Change.   

The aviation industry has not been complacent, but rather has made significant progress in reducing its impact on the environment since the beginning of the jet age nearly 40 years ago.  Advancements in technology have resulted in a 70% reduction in fuel consumption, and therefore CO2 emissions (CO2 emissions from aircraft are directly proportional to the amount of aviation fuel consumed), when compared to original commercial jets. 

CO2 emissions are an important global environmental issue.  As a leader of the air cargo industry, TIACA recognizes our environmental responsibilities and is committed to working in partnership with governments and industry representatives to address aviation's impact on the environment.  TIACA strongly supports a global approach to addressing this global issue.

In this regard, TIACA supports the leadership role of the International Civil Aviation Organization (ICAO), and the joint industry targets developed by the International Air Transport Association (IATA) and endorsed by the Air Transport Action Group (ATAG), i.e., an average annual fuel efficiency improvement of 1.5% to 2020, carbon neutral growth from 2020, and the aspirational goal of a net 50% reduction in 2005 carbon dioxide emission levels by 2050.

Aviation and Global Climate Change in the 21st Century (April 2009)

Findings:
The authors that had assessed aviation's contribution to climate change to be 3% in the Fourth Assessment Reports (AR4) is now estimating aviation's contribution to climate change to be 3.5% without cirrus and 4.9% with cirrus.

TIACA’s View:
The Intergovernmental Panel on Climate Change (IPCC) states in its 1999 report on aviation and climate change that airplanes emit 2% of man-made CO2 in 1992 and is expected to grow to 3% in 2050. The Aviation and Global Climate Change in the 21st Century report contains CO2 data that indicates aviation remains 2% of anthropogenic CO2.

Aviation is the only industry that has asked the IPCC for a total assessment on climate change. The original assessment done in 1999 used RF as a way to assess the impact beyond CO2. Given the considerable uncertainty of the other gases, particularly those like aviation-induced cloudiness (AIC) that is unique to aviation, a more direct and understood comparison of aviation to other anthropogenic actives is better done via CO2.

TIACA, however, will continue to monitor what effects other gases (NOx, H2O vapor, contrails, AIC, sulphate particles, and soot particles) have on climate change and as more is understood what these effects are, we will be in a better position to correctly address how aviation can reduce its impact on the environment.

FAQs

Q. What are your thoughts on the EU ETS? What is TIACA's policy on emissions trading schemes? Do you think there should be a global scheme, and what lobbying, if any, are you doing to see that that happens? Are you working with IATA?

A. Reducing aviation’s environmental impact is one of our top priorities. TIACA believes this is a global issue that requires a global approach. We believe that working with ICAO and its current Group on International Aviation and Climate Change (GIACC) to come to an agreed common, global approach, rather than individually or regionally imposed ETS systems, would yield a greater impact in reducing aviation’s emissions.

As issues pertaining to air cargo and the environment arise, we are in contact with IATA as well as relevant policymakers in the EU and in other countries to voice our members’ concerns and to communicate our support for a global approach. We have and will continue to work closely with IATA and other associations to expand cooperation and coordination on this and other key issues for the air cargo industry.

Q. How have you been supporting the cargo carriers? What are the airlines saying to you?

A. Our members, both all-cargo and passenger airlines, have emphasized the difficulties they would face in complying with a variety of emissions schemes imposed by various countries around the world. They also believe it is important that any policy take into account the fact that aviation represents approximately 2% of global carbon dioxide emissions and is projected to grow to only about 3% by 2050.

Furthermore, the industry, of its own volition, has a significant track record of reducing fuel consumption and thus greenhouse gas emissions.  Since the beginning of the jet age nearly 50 years ago, technology has advanced the aviation industry to achieve incredible reductions in the environmental impact of airplanes. These advancements in technology have resulted in a 70% reduction in fuel consumption and therefore CO2 emissions (CO2 emissions from aircraft are directly proportional to the amount of aviation fuel consumed). In addition, today’s airplanes are 30dB quieter – or a 90% reduction in the noise footprint when compared to original commercial jets. This improvement trend will continue with the newest generation of airplanes, which offer an additional 15-25% improvement in fuel consumption and hence CO2 emission.

Q. Are there any particular issues surrounding emissions trading schemes which affect the air freight industry and not the passenger business?

A. The issue of “food miles” is particularly important for the air freight industry. The concept is misleading to the consumer, and fails to acknowledge air cargo’s contribution to economic development. “Food miles” fails to measure the true carbon footprint of a food product through the entire life cycle from production to consumption. Labeling that identifies the carbon footprint of a product should not just be limited to air transport, as this is only one link of the entire supply chain. Differences in food production and availability of resources in different parts of the world impact the carbon footprint of the product. For example, flowers grown in Kenya and then air freighted to Europe can have substantially less total CO2 emissions than home-grown product under artificial conditions.

Furthermore, food miles discount air cargo’s role as an engine for economic development. Air cargo allows remote agricultural regions to access world markets. The success of these operations depends on rapid, efficient and reliable delivery of the consignment in the best possible condition, with minimum loss or damage. Airfreight is the only transport means to these imperative ends.

Q. Some airlines believe industry bodies have been slow to act on environmental issues. What is your response to that?

A. As with any issue and any sector, there will always be differences of opinion and certain players who may want to move faster and farther than others. As an industry association, TIACA’s responsibility is to give due consideration to the interests of all its members, and therefore we need some time to come to agreement on a common position on major issues. We will continue working to be as responsive as possible on issues, while simultaneously ensuring that our members have input into our decision-making process. This may mean we need a bit of time to finalize a position, but we will make every effort to ensure that our representations are timely.

Q. Do emissions trading schemes affect the air cargo industry in a different way from the passenger side of the business?

A. Under the EU ETS Directive there is no differentiation between passenger and cargo aircraft and so we would not expect the emissions trading schemes to affect the air cargo industry differently from the passenger industry.
