Airlines would try to reduce emissions themselves. Those that emit more could purchase emission reductions (such as carbon credits)\u00a0from other sectors that have cut emissions below specified levels.<\/span><\/p>\n<p>Over time, the cap would ratchet down, in keeping with the Paris goal. Airlines\u2019 investments would promote greater energy efficiency in aircraft \u2013 and, through the use of verified carbon offsets \u2013 support sustainable low-carbon development outside the sector.<\/p>\n<p>For example, an airline could invest in helping <a href=\"https:\/\/dialogue.earth\/en\/climate\/7670-china-could-get-2-of-ghg-cuts-from-farming\/\">farmers<\/a> in\u00a0China <a href=\"https:\/\/e360.yale.edu\/feature\/china_turns_to_ecological_biogas_production_to_ease_impact_of_factory_livestock_farms\/2338\/\">cut methane pollution<\/a> from agricultural waste\u00a0by converting to biogas fuels.<\/p>\n<p>The resulting emission reductions could help offset the airline\u2019s emissions and generate new income for the farmers. An airline could help city-dwellers switch to carbon-free energy sources; the reductions could help offset the airline\u2019s carbon emissions and combat urban air pollution.<\/p>\n<p><strong>What stands in the way of agreement?<\/strong><\/p>\n<p>The MBM sounds like a great idea.

Under\u00a0that convention, different carriers competing on the same routes should not be subject to differential regulation in ways that would distort markets.<\/p>\n<p dir=\"ltr\">China voiced its disapproval of\u00a0such a\u00a0cap, adding that<span id=\"docs-internal-guid-a20d5b1f-2912-b082-d9fd-d1be2ce51f50\">\u00a0\u201cwithout differentiated responsibilities will impede the future development of international aviation of developing countries.\u201d While China supported emission reduction goals for the sector, it said \u201cdeveloped countries should take the lead in taking reduction measures in order to offset the growth in emissions from international aviation of developing countries.\u201d \u00a0<\/span><\/p>\n<p>How to achieve carbon-neutral growth from 2020, while differentiating, and without distorting markets, is the central challenge for the ICAO Assembly. In principle the MBM could hold each airline responsible for offsetting its own emissions above 2020 levels, or for offsetting an amount proportional to the industry\u2019s average emissions above 2020.<\/p>\n<p>But these methods don\u2019t provide much differentiation. Another possibility is that in light of the <a href=\"https:\/\/www.wri.org\/indc-definition\">national commitments<\/a> made in\u00a0Paris, each aviation nation could put forward its own nationally determined aviation contribution.<\/p>\n<p>But that could generate market distortion, not to mention a regulatory patchwork \u2013 which is just what China and others objected to when the EU, in 2013, regulated flights in and out of Europe under its emissions trading system.<\/p>\n<p>Others have suggested providing differentiation by exempting large groups of countries from the MBM. \u00a0But that would punch holes in the emissions cap, without addressing differentiation among covered countries.<\/p>\n<p>Another option would be to keep the 2020 cap for all, but set each geographic region\u2019s share of the global offset obligation proportional to that region\u2019s share of global traffic.<\/p>\n<p><strong>Proportionate?<\/strong><\/p>\n<p>This would provide differentiation, since historically undeserved regions would have smaller shares of the offset obligation, while historically high-traffic regions would shoulder a larger share.<\/p>\n<p>Within each region, each operator\u2019s offset obligation would be set in proportion to its share of regional traffic. \u00a0This would ensure no discrimination on routes within each region. And the system would be updated regularly to take into account changes in regional growth and shifts in airline market share.<\/p>\n<p>Whether such an approach could help countries reach agreement remains to be seen.<\/p>\n<p><strong>Measuring emissions <\/strong><\/p>\n<p>Nations will need to agree on transparent rules for measuring and reporting the emissions of all flights covered by the MBM. Such rules need not be onerous; airlines already measure fuel burn for economic and safety reasons.<\/p>\n<p>So what kinds of emissions units can airlines use? \u00a0ICAO is an aviation body, not an emissions body. So it is unlikely ICAO will establish its own out-of-sector emission reduction programmes.\u00a0But ICAO could adopt criteria that emissions unit programmes would need to meet to provide emissions units to market mechanisms.<\/p>\n<p dir=\"ltr\">To ensure a level flying field, those criteria would need to be mandatory. And steps must be taken to ensure that the emissions units haven\u2019t already been claimed toward meeting a country\u2019s emissions limitation obligations under other commitments, for example\u00a0Paris.<\/p>\n<p><strong>Transparency<\/strong><\/p>\n<p>Full and transparent review of the programme every three to five years will be essential to ensure that it is operating effectively, and over time to ratchet the cap down in line with the Paris Agreement.<\/p>\n<p>Taken together, the \u201cbig five\u201d make the MBM a tall order for ICAO. The UN&#8217;s aviation arm\u00a0has managed to develop some 10,000 standards over the years \u2013 but the MBM is shaping up to be one of its biggest challenges. Whether it will meet this challenge is not clear. But what is apparent\u00a0is that the aviation industry\u2019s licence to grow depends on how it deals with its carbon footprint.\u00a0And that puts the spotlight on ICAO and its 2016 assembly to achieve the real deal in a transparent manner.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aviation\u2019s upcoming proposals on a carbon\u00a0cap will have to solve five tricky problems, writes Annie Petsonk<\/p>\n","protected":false},"author":2397,"featured_media":58647,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[760],"tags":[513],"hashtags":[],"country":[],"class_list":["post-33829","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pollution","tag-carbon-emissions"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v26.0) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Can airlines cap their carbon emissions?
