All Aircraft Could Fly on Sustainable Fuel by 2030- Report

Published

The Sustainable Aviation Fuels as a Pathway to Net-Zero Aviation Report shows that a transition to carbon-neutral flying is possible, with SAF the most promising decarbonization option in the near term.

There are enough sustainable, renewable feedstocks to fuel all aviation using SAF by 2030. Scaling up SAF production to meet the net-zero ambition, however, depends on several new technology routes and significant multistakeholder collaboration. The main challenge will be developing appropriate commercial, financing, incentives and regulatory mechanisms.

SAF as a feasible route to net-zero aviation

In 2019, aviation accounted for 3% of human-made carbon emissions. Hybrid-electric and hydrogen-powered aircraft could help the industry reach the next efficiency target, but development and deployment at scale could take 10 to 20 years and the technology will initially be limited to smaller, shorter-range aircraft.

Furthermore, in 2019, fewer than 200,000 metric tons of SAF were produced globally, a tiny fraction of the roughly 300 million tons of jet fuel used by commercial airlines.

More positively, SAF has already fuelled more than one-quarter of a million commercial flights and is compatible with existing aircraft and fuelling infrastructure.

Even following the challenge to aviation during the COVID-19 pandemic, members of the CST coalition are continuing their commitment to drive energy transition in aviation towards the goal of net-zero aviation.

An economic opportunity for developing markets

Aviation delivers significant benefits globally, not least to developing markets, from where a sizeable portion of global aviation demand is expected to come. The current crisis may also present an opportunity for countries with low renewable power prices and ready access to feedstock. If these countries act now, they can benefit from energy transition in aviation and become global SAF production hubs.

“The structural changes happening in the industry are an opportunity to rebuild and transition towards a low-carbon future and meet the sustainability demands of its consumers,” said Christoph Wolff, Head of Mobility Industries at the World Economic Forum.

To this end, the CST initiative is working on a pilot project to create a SAF sector in India and plans to replicate this process in other markets that have the necessary conditions to foster a valuable SAF industry.

Building scale is key to improving cost

This report, written in collaboration with McKinsey & Company, shows that despite feedstock availability and even if all currently announced SAF projects are completed, capacity will only increase to approximately 4 million tons annually, which equates to approximately 1% of global jet fuel demand in 2030.

Currently, SAF is more than double the cost of conventional fuel. As further innovations and efficiencies of scale in production are achieved, prices will drop.

“We see the classic Catch-22 problem as in other energy transition discussions. Insufficient scale drives per unit costs high and high costs keep demand low. Some structural solutions could break this impasse – B2B contracts, prioritized aviation and airport fee structures etc. that will give fuel producers the required support to invest in production capacity,” said Daniel Riefer, Associate Partner, McKinsey & Company.

Investments can accelerate promising new technologies

Fuels produced from used cooking oil and other lipids will contribute most to developing capacity in the short term. New technologies take time to mature and develop, but investment decisions, including building larger demonstration plants, are needed now.

Power-to-liquid fuels can contribute the most to SAF capacity, but will only prove effective after 2030 under current development plans. Fuels made from CO2 and green electricity will require financial support for their technology to mature and will need access to renewable electricity.

There is no silver bullet for net-zero aviation. No single feedstock will be practical in every geography or yield enough SAF to meet all demand. Even as costs fall, SAF will have higher production costs than fossil fuels, though a rising carbon price may enable parity in the 2030s.

While the report demonstrates that enough feedstocks are available globally to make SAF economically viable and scalable, several factors are required. These include supportive regulatory frameworks, measures to stimulate demand from corporate and private customers, and innovative ways to finance the transition. The CST coalition is debating how to meet these challenges and help aviation earn its right to keep growing.

Clean Skies for Tomorrow

The World Economic Forum’s CST initiative, established in 2019, is a mechanism for leaders throughout aviation’s value chain to facilitate the transition to net-zero aviation by mid-century. In partnership with ambitious senior leadership throughout industry, government and civil society, this public-private partnership is driving a shift to zero-emissions aviation through SAF and other clean propulsion technologies.

Action on Trade is Necessary for Businesses to Unlock Net Zero Targets

Published

on

business

For businesses to reach their emission targets, the global trading system needs to adapt, and businesses are calling for the change.

These are the main findings of the Delivering a Climate Trade Agenda: Industry Insights Report released today by the World Economic Forum, in collaboration with Clifford Chance.

The six-month study is based on research and interviews with global companies, across sectors including transport, energy, manufacturing, and consumer goods. The objective of the research process was to identify necessary changes to the current global trade system and how to better incentivize and accelerate decarbonization. The resulting study outlines eight key actions that, if taken by governments and businesses, could make global trade a better enabler of climate action.

Sean Doherty, Head of International Trade and Investment said: “Traditionally, trade and climate policy-making has happened in separate silos. The urgency of the climate crisis calls for us to break down these silos through public-private cooperation in order to accelerate emissions reductions while achieving prosperity for all. The good news for policy makers is businesses are ready and willing to support this change.”

Jessica Gladstone, Partner at Clifford Chance said: “International trade will play a key role in achieving a just transition to a low-carbon sustainable global economy. Businesses stand ready to lead in this transition, but governments can support by ensuring the right legislative and regulatory structures are in place. Our report explores global and domestic policy actions that can create climate-friendly trade that is fair, transparent, and has technology and innovation at its core.”

Interviews revealed the following ways for trade to support businesses to decarbonize and grow sustainably:

  • Tariff reductions on key goods
  • Addressing non-tariff distortions in parallel
  • Phasing out fossil fuel subsidies
  • Building coherence around carbon-based trade policies
  • Supporting trade in digital and climate-related services
  • Encouraging climate-smart agriculture
  • Aligning trade agreements with climate commitments
  • Facilitating green investment

The chart below provides examples of how the global trading system can through continued dialogue between governments and the private sector put trade to the service of climate action.

The report includes a jointly-authored foreword by the World Trade Organization (WTO) Director General Ngozi Okonjo-Iweala and the United Nations Framework Convention on Climate Change (UNFCCC) Executive Secretary welcoming the insights from business. Major intergovernmental meetings will be held under both organisations in the last quarter of this year.

Business can take steps to encourage alignment of trade rules with climate action. The Forum is today launching a two-year work programme – titled Climate Trade Zero – to support public and private exchange on these issues as part of building a more sustainable trading system.

Many companies also recognized that the transition is taking place at different speeds and levels of intensity across countries and sectors. Interviewees highlighted the importance of providing support and incentives to developing countries, and to supply chain partners in developing countries, to undertake the investments necessary to reduce their emissions.

Appliance standards and labelling is highly effective at reducing energy use

Published

on

Policies that introduce minimum efficiency performance standards and energy-consumption labelling on appliances and equipment have led to reduced power consumption, lower carbon emissions, and cost savings for consumers, according to analysis published today by the IEA and the 4E Technology Collaboration Programme (4E TCP).

The report’s findings are drawn from nearly 400 evaluation studies covering 100 countries, including those with the longest running and strongest appliance policies, such as China, European Union, Japan and the United States.

“The findings from the study are important as they provide evidence that standards and labelling are highly effective policy instruments that bring benefits to consumers as well as lower emissions and lower energy demand,” said Brian Motherway, the Head of Energy Efficiency at the IEA.

The study shows the policies have had significant positive impacts:

  • In countries with long-running policies, appliances are now typically consuming 30% less energy than they would have done otherwise.
  • In the nine countries/regions for which data were available, such programmes reduced annual electricity consumption by a total of around 1 580 terawatt-hours in 2018 – similar to the total electricity generation of wind and solar energy in those countries.
  • The programmes that have been operating the longest, such as those in the United States and the European Union, are estimated to deliver annual reductions of around 15% of their current total national electricity consumption. This percentage increases each year as more of the older, less-efficient stock is replaced with equipment that meets new higher efficiency standards.
  • These energy savings represent a significant financial boon for businesses and householders. In the United States alone, utility customers are now economising USD 60 billion each year, or USD 320 per customer.
  • Also, the United States, European Union and China together are avoiding annual CO2 emissions of more than 700 million tonnes, equivalent to the total energy-related emissions of Germany.
  • Well-designed policies encourage product innovation and lead to economies of scale, which reduces the cost of appliances even without accounting for the efficiency gains. For example, in Australia the sticker price of appliances has typically fallen 40% over the last 20 years, while average energy consumption has fallen by a third.

“The message is simple: expanding standards and energy efficiency labelling programmes makes the energy transition challenge easier, more affordable and become a reality,” said Jamie Hulan, the Chair of the 4E TCP.

The IEA will continue to collaborate with 4E TCP to enhance and promote the use of such policies. 4E TCP is an international platform for fourteen countries and the European Union to exchange technical and policy information focused on increasing the production and trade in efficient end-use equipment.

Ahead of this November’s COP26 Climate Change Conference, the IEA is working with the UK Government via the Super-Efficient Equipment and Appliance Deployment (SEAD) initiative to coordinate and improve international action on product energy efficiency. The United Kingdom is leading the COP26 Product Efficiency Call to Action, which aims to double the efficiency of key global products by 2030, initially focusing on four key energy-consuming products: air conditioners, refrigerators, lighting and industrial motors systems. The IEA is supporting the implementation of this work and helping expand the number of countries ready to make this commitment.

Global economy projected to show fastest growth in 50 years

Published

on

The global economy is expected to bounce back this year with growth of 5.3 per cent, the fastest in nearly five decades, according to the UN Conference on Trade and Development (UNCTAD).

In its new report released on Wednesday, the agency said that the rebound was highly uneven along regional, sectoral and income lines, however.  

During 2022, UNCTAD expects global growth to slow to 3.6 per cent, leaving world income levels trailing some 3.7 per cent below the pre-pandemic trend line. 

The report also warns that growth deceleration could be bigger than expected, if policymakers lose their nerve or answer what it regards as misguided calls for a return to deregulation and austerity. 

Differences in growth 

The report says that, while the response saw an end to public spending constraints in many developed countries, international rules and practices have locked developing countries into pre-pandemic responses, and a semi-permanent state of economic stress. 

Many countries in the South have been hit much harder than during the global financial crisis. With a heavy debt burden, they also have less room for maneuvering their way out through public spending. 

Lack of monetary autonomy and access to vaccines are also holding many developing economies back, widening the gulf with advanced economies and threatening to usher in another “lost decade”. 

“These widening gaps, both domestic and international, are a reminder that underlying conditions, if left in place, will make resilience and growth luxuries enjoyed by fewer and fewer privileged people,” said Rebeca Grynspan, the secretary-general of UNCTAD. 

“Without bolder policies that reflect reinvigorated multilateralism, the post-pandemic recovery will lack equity, and fail to meet the challenges of our time.” 

Lessons of the pandemic 

UNCTAD includes several proposals in the report that are drawn from the lessons of the pandemic. 

They include concerted debt relief and even cancellation in some cases, a reassessment of fiscal policy, greater policy coordination and strong support for developing countries in vaccine deployment. 

Even without significant setbacks, global output will only resume its 2016-19 trend by 2030. But even before COVID-19, the income growth trend was unsatisfactory, says UNCTAD. Average annual global growth in the decade after the global financial crisis was the slowest since 1945. 

Despite a decade of massive monetary injections from leading central banks, since the 2008-9 crash, inflation targets have been missed. Even with the current strong recovery in advanced economies, there is no sign of a sustained rise in prices. 

After decades of a declining wage share, real wages in advanced countries need to rise well above productivity for a long time before a better balance between wages and profits is achieved again, according to the trade and development body’s analysis. 

Food prices and global trade 

Despite current trends on inflation, UNCTAD believes the rise in food prices could pose a serious threat to vulnerable populations in the South, already financially weakened by the health crisis. 

Globally, international trade in goods and services has recovered, after a drop of 5.6 per cent in 2020. The downturn proved less severe than had been anticipated, as trade flows in the latter part of 2020 rebounded almost as strongly as they had fallen earlier. 

The report’s modelling projections point to real growth of global trade in goods and services of 9.5 per cent in 2021. Still, the consequences of the crisis will continue to weigh on the trade performance in the years ahead. 

For director of UNCTAD’s globalization and development strategies division, Richard Kozul-Wright, “the pandemic has created an opportunity to rethink the core principles of international economic governance, a chance that was missed after the global financial crisis.” 

“In less than a year, wide-ranging US policy initiatives in the United States have begun to effect concrete change in the case of infrastructure spending and expanded social protection, financed through more progressive taxation. The next logical step is to take this approach to the multilateral level.” 

The report highlights a “possibility of a renewal of multilateralism”, pointing to the United States support of a new special drawing rights (SDR) allocation, global minimum corporate taxation, and a waiver of vaccine-related intellectual property rights.  

UNCTAD warns, though, that these proposals “will need much stronger backing from other advanced economies and the inclusion of developing country voices if the world is to tackle the excesses of hyperglobalization and the deepening environmental crisis in a timely manner.” 

For the UN agency, the biggest risk for the global economy is that “a rebound in the North will divert attention from long-needed reforms without which developing countries will remain in a weak and vulnerable position.”
