Net-zero carbon emissions from harder-to-abate sectors is technically and financially possible by mid-century

New report by the Energy Transitions Commission shows that reaching net-zero carbon emissions from heavy industry and heavy-duty transport can be done through ambitious policy, accelerated innovation, and investment, with minimal cost to the global economy

Reaching net-zero carbon emissions from heavy industry and heavy-duty transport sectors is technically and financially possible by 2060 and earlier in developed economies and could cost less than 0.5% of global GDP, according to the report published today by the Energy Transitions Commission (ETC).

The report ‘Mission Possible: Reaching net-zero carbon emissions from harder-to-abate sectors’ by mid-century outlines the possible routes to fully decarbonize cement, steel, plastics, trucking, shipping and aviation – which together represent 30% of energy emissions today and could increase to 60% by mid-century as other sectors lower their emissions.

The “Mission Possible” report was developed with contributions from over 200 industry experts over a 6- month consultation process. Its findings show that full decarbonization is technically feasible with technologies that already exist, although several still need to reach commercial readiness. The total cost to the global economy would be less than 0.5% of GDP by mid-century, and could be reduced even further by improving energy efficiency, by making better use of carbon-intensive materials (through greater materials efficiency and recycling) and by limiting demand growth for carbon-intensive transport (through greater logistics efficiency and modal shift).

The report also shows that this would have only a minor impact on the cost of end consumer products. For example:

  • Green steel use would add approximately US$180 on the price of a car.
  • Green shipping would add less than 1% to the price of an imported pair of jeans.
  • Low-carbon plastics would add 1 US cent on the price of a bottle of soda.

In heavy-duty transport, electric trucks and buses (either battery or hydrogen fuel cells) are likely to become cost-competitive by 2030, while, in shipping and aviation, liquid fuels are likely to remain the preferred option for long distances but can be made zero carbon by using bio or synthetic fuels. Improved energy efficiency, greater logistics efficiency and some level of modal shift for both freight and passenger transport could reduce the size of the transition challenge.

In industry, more efficient use of materials and greatly increased recycling and reuse within a more circular economy could reduce primary production and emissions by as much as 40% globally – and more in developed economies – with the greatest opportunities in plastics and metals. Reaching full decarbonization will require a portfolio of decarbonization technologies, and the optimal route to net-zero carbon will vary across location depending on local resources.

Across all sectors of the economy:

  • Direct and indirect electrification (through hydrogen) will likely play a significant role in most sectors of industry and transport, leading to a sharp increase in power demand – growing 4-6 times from today’s 20,000 TWh to reach around 100,000 TWh by mid-century).
  • Hydrogen use will almost certainly increase dramatically (7-11 times by mid-century), with two routes to zero-carbon hydrogen: electrolysis, which will likely dominate in the long term, and steam methane reforming plus carbon capture and storage.
  • Bioenergy and bio-feedstock will be required in several sectors, but will need to be tightly regulated to avoid adverse environmental impact (such as deforestation), and its use should be focused on priority sectors where alternatives are least available or more costly, such as aviation and plastics feedstocks.
  • Carbon capture (combined with use or storage) will likely be required to capture process emissions from cement and may also be the most cost-competitive decarbonization option for other sectors in several geographies. However, it does not need to play a major role in power generation, with the storage needs required could be less than many scenarios suggest. Tight regulation of storage is essential to ensure safety and permanence.

The “Mission Possible” report concludes that the most challenging sectors to decarbonize are plastics, due to end-of-life emissions, cement, due to process emissions, and shipping because of the high cost of decarbonization and the fragmented structure of the industry.

The Energy Transitions Commission supports the objective of limiting global warming ideally to 1.5°C and, at the very least, well below 2°C. In the wake of the IPCC’s urgent call for action, the “Mission Possible” report sends a clear signal to policymakers, investors and businesses: full decarbonization is possible, making ambitious climate objectives achievable.

Key policy levers to accelerate the decarbonization of harder-to-abate sectors include:

  • Tightening carbon-intensity mandates on industrial processes, heavy-duty transport and the carbon content of consumer products.
  • Introducing adequate carbon pricing, strongly pursuing the ideal objective of internationally agreed and comprehensive pricing systems, but recognizing the potential also to use prices which are differentiated by sector, applied to downstream consumer products and defined in advance.
  • Encouraging the shift from a linear to a circular economy through appropriate regulation on materials efficiency and recycling.
  • Investing in the green industry, through R&D support, deployment support, and the use of public procurement to create initial demand for “green” products and services.
  • Accelerating public-private collaboration to build necessary energy and transport infrastructure.

Industries and investors can anticipate the profound transformation in industry and transport they will eventually face by innovating and investing in decarbonization technologies and low-carbon infrastructure. The ETC provides the fact base for industry groups and private companies to develop roadmaps, collaborations and projects aiming for net-zero carbon emissions in their sectors. It also encourages businesses across multiple sectors to question their procurement practices and make commitments to buying “green” products and services.

The members of the Energy Transitions Commission are committed to achieving the Paris objective of limiting the rise in global temperatures to well below 2 ̊C and as close as possible to 1.5 ̊C. They are convinced that succeeding in that historic endeavor would not only limit the harmful impact of climate change, but would also drive prosperity and deliver important local environmental benefits.

Adair Turner, co-chair of the ETC said, “This report sets out an optimistic but completely realistic message – we can build a zero-carbon economy with a minor cost to economic growth. We should now commit to achieving this by 2060 at the latest, and put in place the policies and investments required to deliver it.”

Ajay Mathur, co-chair of the ETC added, “Climate change imperatives, underlined most recently in the IPCC Special Report to limit global warming to 1.5°C, require the world to move to near-zero carbon emissions by the 2060s or so – when many of the investments we make today would still be operational. The ETC report provides pragmatic steps to move towards zero-carbon technology options in these harder-to-abate sectors, providing both hope as well as strategic directions in these sectors.”

About the Energy Transitions Commission

The Energy Transitions Commission (ETC) brings together a diverse group of individuals from the energy and climate communities: investors, incumbent energy companies, industry disruptors, equipment suppliers, energy-intensive industries, non-profit organizations, advisors, and academics from across the developed and developing world. Our aim is to accelerate change towards low-carbon energy systems that enable robust economic development and limit the rise in global temperature to well below 2 ̊C. See below the list of ETC Commissioners.

The Mission Possible report was developed by the Commissioners with the support of the ETC Secretariat, provided by SYSTEMIQ. It draws upon a set of analyses carried out by Material Economics, McKinsey & Company, University Maritime Advisory Services and SYSTEMIQ for and in partnership with the ETC, as well as a broader literature review.

Emerging findings were subject to a 6-month consultation process through which we received inputs from nearly 200 experts from companies, industry initiatives, international organizations, non-governmental organizations and academia, whom we would like to warmly thank for their contributions.

This report constitutes a collective view of the Energy Transitions Commission. Members of the ETC endorse the general thrust of the arguments made in this report, but should not be taken as agreeing with every finding or recommendation. The institutions with which the Commissioners are affiliated have not been asked to formally endorse the report.
