Shipping emissions: Route optimisation using ocean currents and eddies may save 10% fuel use globally

An Australian scientist proposes freight and container ships optimise their routes based upon satellite data and a AI algorithm based upon the mapping of ocean currents and ocean eddies. 

This could save a freight route between Sydney and Wellington in New Zealand about 17 percent fuel use, with minimal deviation and change in delivery time. It could achieve these savings by tracking the flow of a large anticlockwise eddy in the Tasman Sea.

Projecting this globally: global shipping industry could potentially cut its total fuel usage by 10 per cent with his route optimisation algorithm, Estimated savings are projected to be nearly US$50 billion and 237 million tonnes of CO2 emissions every year.

Shane Keating is an oceanographer and associate professor of applied mathematics at UNSW Sydney. He has developed an application and is offering it through his just-launched UNSW spin-off company named Ocean Intelligence. 

“It’s essentially Google Maps for the sea, which offers the most efficient route in real time based on the behaviour of ocean eddies,” Keating said in this article in the Saturday Paper.

Addressing shipping emissions with Professor Alice Larkin in interview with Kevin Anderson

Shipping emissions is one of those niche areas, part of Transport emissions, that needs to be tackled. There is both a huge freight and logistics component, a smaller passenger component and the tourism component of cruise ships.

Most of the interview is focussed on the Freight component. About 3 percent of global emissions are due to shipping. This is about equivalent to the emissions of Germany.

The shipping sector is large, complex, with many different vessels, many actors. 

About a third of all goods transported by ship are fossil fuels: coal, oil and gas. So the implementation of the Paris Agreement should see a reduction in transport of fossil fuels.

Other major areas are the transport of consumer goods in container vessels, and bulk carriers such as carrying iron ore or minerals or food and grains.

Freight Decarbonisation for Australia addresses transport emissions says new ClimateWorks report


Decarbonising freight is critical to decarbonising the transport sector and meeting Australia's climate targets. ClimateWorks has just published a report on Delivering freight decarbonisation: Strategies for reducing Australia’s transport emissions.

In 2021, the transport sector contributed approximately 20 per cent of Australia’s domestic emissions and is likely to become the largest contributor by 2030. Freight makes up a considerable share of transport emissions, estimated by Climateworks to be just under 40 per cent of the transport total. This represents approximately 7 per cent of Australia’s total emissions.

Passenger transport emissions can be addressed through uptake of Electric Vehicles, Fuel Efficiency standards, policies that encourage active transport (walking and cycling) and micro-mobility and use of public transport. This report does not focus on passenger transport emissions.

Satire: Worldwide temperatures offers incredibly ‘hot’ travel deals | while Aviation promotes 'Sustainable' Aviation Fuels


Satirist Mark Humphries does some marketing for the aviation and international travel industry, taking into account current climate conditions in this new Age of Global Boiling. It reflects the amount of travel advertising reliant on boosting aviation, which exacerbates the climate crisis.

Voiceover: "Ironically emissions from air travel are part of the problem".

Meanwhile the Tourism and aviation industry pin their hopes for growth on Sustainable Aviation Fuels (SAF). But these fuels are problematic, not a silver bullet.

Importance of funding active transport infrastructure in Merri-bek budget to 2027

Separated Upfield Bike Path past Moreland Station
On behalf of Climate Action Merribek I sent in a submission to Merri-bek Council on their draft budget 2023-2027 on May 19. You can read the CAMerribek submission in full: Major backtrack on active transport projects in Draft Merri-bek Council Budget jeopardizes Climate Targets.  

Tonight, 29 May 2023, I fronted before Council Budget committee to speak to this presentation. There were a substantial number of submissions on Council Budget, evidently more than half focussed on the need for funding for more active transport infrastructure as a priority with many people opting to speak in person or online to Council on their submission.

My speech is below. As I only had 2 minutes to deliver, I excised a few paragraphs as marked with brackets, and still went slightly over..

There were some excellent presentations from citizens from Glenroy, Fawkner, Coburg North, Coburg, Brunswick West and Brunswick highlighting different facets of the problem, often with personal stories.

I have also included key findings of a new Climate Council report on Decarbonising Transport which support my presentation arguments and that of the CAMerribek submission.

Shift Away from 'Car-Centric' Transport System needed | Climate of the Nation 2022

The shift away from 'car-centric' system and car dependency is needed to address transport emissions. That means funding public transport, walking and cycling to adequate levels.

The UN recommends that 20 per cent of the transport budget should be allocated to walking and cycling. Here in Australia it is usually less than 1 per cent.

There is a huge potential here for mobility behaviour change, if the infrastructure is put in place. Some 78 percent of people are in the interested but concerned cohort (Pearson 2022). Recent statistics from RACV show that bikes are now outselling cars.

The Climate of the Nation survey has been done each year since 2007. This year it included a section on transport and transport emissions.

Australians believe 20% of government transport spending should go to active transport, the same as the minimum recommended by the United Nations.

Three-fifths (62%) support having a national subsidy scheme for bikes, e-bikes or cargo bikes, and three-quarters (75%) support electrifying state bus fleets by 2030.

Victoria cut emissions by 29.8% on 2005 levels by 2020. There is a pathway to decarbonisation by 2035 to meet 1.5C target.


The Victorian Premier, Dan Andrews, announced on 20 September that Victoria Smashes Emissions Targets. Victoria achieved a 29.8 per cent emissions cut on 2005 levels up to and including 2020. Victoria had set an Emissions Reduction Target of 15 to 20 per cent reduction by 2020.

Last year i reported that Victoria reduced emissions by 24.8%, on track for 45-50% reduction by 2030

The Andrews Government rebuilt Victoria's Climate Act and set a number of interim targets. 

Energy was the top sector that needed to start the decarbonisation transition process, and the Andrews Government has tackled this with growing renewables and energy storage as a proportion of our electricity production.

Victoria’s energy sector is still the state’s largest source of emissions, but continues to see deep cuts made due to the rapid upscaling of renewable energy. The sector saw renewable electricity production increase from 21.7% of total electricity generation in 2019 to 24.8% in 2020.

Aviation exhaust pollution, air quality, and impacts on Human Health - Melbourne Airport 3rd runway expansion

Melbourne Airport with 3 runways 2026 Option 1, Night 11pm-6am Flight Paths


Melbourne Airport is planning a third runway.

So I'm doing a science literature dive into reading the air pollution health impacts of aviation emissions...

You know, that coating you find over your car or house if you live under a flight path...this is soot, black carbon (BC), particulate pollution emissions from aircraft landing and taking off. But it's the particles you don't see that are problematic: Ultra Fine Particles (UFP) sometimes referred to as particulate matter with a size designation often classified as PM2.5, but often even smaller which can reach the furthest alveoli of your lungs..

These pollution particulates are not good for your health. UFPs have a high surface area and a capacity to adsorb a substantial amount of toxic organic compounds.

Studies indicate that the "exposure to aircraft emissions induce pulmonary and systemic inflammation, which potentially contributes to cancer, asthma, respiratory and coronary heart disease." (Bendtsen 2021)

In fact it is calculated that aviation emissions on a global basis cause about 16,000 people to die prematurely every year, and of this number about 5,000 people who live within 20 km of airports are estimated to die prematurely each year.

As Steve H L Yim et al (2015) study says: " primary PM2.5 emissions from aviation are a significant contributor to health risk when airport vicinity exposure is captured."

The study also highlights that the health cost of aviation emissions is actually at a magnitude larger than global aviation fatal accident costs, and on par with aviation's climate costs.

I wonder if Melbourne Airport have done their sums on the extra costs to health of people in the 20km radius of the airport with the extra aviation emissions a third runway will induce?


The No Third Tulla Runway campaign has articulated reasons to oppose development of the third runway. These include:
These are all relevant reasons to oppose the airport. The missing piece in this analysis is the aviation pollution impacts on air quality and human health at all scales: local, regional and global.

This article seeks to draw attention to some of the science on aviation exhaust emissions, air quality and human health.

Transport Day at COP26: aviation, shipping, EVs but don't mention cycling, micro-mobility or public transport


Wednesday 10 November was designated transport day at the UN Climate conference COP26. After the energy sector, the transport sector needs to be decarbonised. Decarbonisation of electricity grids will substantially contribute and assist in reducing transport emissions.

The UK Government used their position as COP26 Presidency for 3 specific declarations, all areas that need to be addressed. But on public transport, e-mobility, cycling, and walking infrastructure and change in mobility behaviours very little.

UN Secretary General on Sustainable Transport (14 October)

The UN Secretary General Antonio Guterres slammed the IMO for its slow progress on shipping emissions at the Second Global Sustainable Transport conference on 14 October 2021:

“We must accelerate the decarbonization of the entire transport sector.

“Let’s be honest. While member states have made some initial steps through the International Civil Aviation Organization and the International Maritime Organization to address emissions from shipping and aviation, current commitments are not aligned with the 1.5-degree goal of the Paris Agreement.

“In fact, they are more consistent with warming way above 3 degrees. 

“Adopting a new set of more ambitious and credible targets that are truly consistent with the goals of the Paris Agreement must be an urgent priority for both these bodies in the months and years ahead.

The priorities are clear:

  • Phase out the production of internal combustion engine vehicles by 2035 for leading manufacturing countries, and by 2040 for developing countries.
  • Zero emission ships must be the default choice, and commercially available for all by 2030, in order to achieve zero emissions in the shipping sector by 2050.
  • Companies must start using sustainable aviation fuels now, in order to cut carbon emissions per passenger by 65 per cent by 2050.
  • All stakeholders have a role to play, from individuals changing their travel habits, to businesses transforming their carbon footprint.
  • Governments must incentivize clean transport options, including through standards and taxation, and impose stricter regulation of infrastructure and procurement.

“In developed countries, transport policies that encourage cycling and walking in urban areas, rather than driving short distances, can contribute to progress across the SDGs: on climate, health, pollution and more.

“Sustainable railway systems should be upgraded and expanded for medium and long-distance travel for people and goods, to increase efficiency and encourage shifts in behaviour.

“Second, we must close access and safety gaps.

“This means helping more than one billion people to access paved roads, with designated space for pedestrians and bicycles, and providing convenient public transit options.

“It means providing safe conditions for all on public transport by ending harassment and violence against women and girls, and reducing deaths and injuries from road traffic accidents.”

Cycling and related organisations have written an open letter: COP26: Government leaders must commit to boosting cycling levels to reduce carbon emissions and reach global climate goals quickly and effectively. We have seen many cities already doing this, especially in Europe, but also North America.

The declaration calls for all governments and leaders at COP26 to:

  • Declare commitments to significantly boost cycling levels at home. This can be done by:
  • Promoting cycling in all its forms, including cycling tourism, sports cycling, bike sharing, riding to work or school and for exercising
  • Recognising cycling as a climate solution, establishing a clear link between how an increase in bicycle trips and a decrease in private car trips reduce CO₂ emissions
  • Creating and financing national cycling strategies and collecting data on cycling to know where improvements in infrastructure and usage can be made
  • Focusing investments on building safe and high-quality cycling infrastructure and in incentives for communities historically marginalised from cycling
  • Providing direct incentives for people and businesses to switch from automobiles to bicycles for more of their daily trips
  • Building synergies with public transport and foster combined mobility solutions for a multimodal ecosystem capable of covering all user needs without relying on a private car
  • Collectively commit to achieving a global target of higher cycling levels. More cycling in a handful of countries will not be enough to reduce global CO₂ emissions. All countries must contribute, and these efforts must be tracked at the UN level.


Climate Home news also pickup on this silence on public transport and active transport: As Cop26 car pledge underwhelms, delegates ask: where are the bikes?

COP26 declaration: zero emission cars and vans

The COP26 declaration on zero emission cars and vans is a landmark global agreement launched by the UK COP presidency to signal the end of polluting vehicles.

The declaration aims for all sales of new cars and vans being zero emission globally by 2040, and by no later than 2035 in leading markets

A. As governments, we will work towards all sales of new cars and vans being zero emission by 2040 or earlier, or by no later than 2035 in leading markets.

B. As governments in emerging markets and developing economies, we will work intensely towards accelerated proliferation and adoption of zero emission vehicles. We call on all developed countries to strengthen the collaboration and international support offer to facilitate a global, equitable and just transition.

C. As cities, states, and regional governments, we will work towards converting our owned or leased car and van fleets to zero emission vehicles by 2035 at the latest, as well as putting in place policies that will enable, accelerate, or otherwise incentivise the transition to zero emission vehicles as soon as possible, to the extent possible given our jurisdictional powers.

D. As automotive manufacturers, we will work towards reaching 100% zero emission new car and van sales in leading markets by 2035 or earlier, supported by a business strategy that is in line with achieving this ambition, as we help build customer demand.

E. As business fleet owners and operators, or shared mobility platforms, we will work towards 100% of our car and van fleets being zero emission vehicles by 2030, or earlier where markets allow.

F. As investors with significant shareholdings in automotive manufacturers, we will support an accelerated transition to zero emission vehicles in line with achieving 100% new car and van sales being zero emission in leading markets by 2035. We will provide proactive engagement and escalation of these issues with investees, coupled with encouraging all our holdings to decarbonise their fleets in line with science-based targets.

G. As financial institutions, we confirm our support for an accelerated transition to zero emission vehicles in line with achieving 100% new car and van sales being zero emission in leading markets by 2035, supported by making capital and financial products available to enable this transition for consumers, businesses, charging infrastructure and manufacturers.

H. As other signatories, we support an accelerated transition to zero emission vehicles in line with achieving 100% of new car and van sales being zero emission in leading markets by 2035.

Almost as a footnote, other forms of travel are included in this declaration:

We recognise that alongside the shift to zero emission vehicles, a sustainable future for road transport will require wider system transformation, including support for active travel, public and shared transport, as well as addressing the full value chain impacts from vehicle production, use and disposal.

  • support the establishment of green shipping corridors – zero-emission maritime routes between 2 (or more) ports.
  • support the establishment of at least 6 green corridors by the middle of this decade
  • aspiration to see many more corridors in operation by 2030
  • facilitate the establishment of partnerships, with participation from ports, operators and others along the value chain, to accelerate the decarbonisation of the shipping sector and its fuel supply through green shipping corridor projects

Signatories: Australia, Belgium, Canada, Chile, Costa Rica, Denmark, Fiji, Finland, France, Germany, Republic of Ireland, Italy, Japan, Republic of the Marshall Islands, Morocco, Netherlands, New Zealand, Norway, Spain, Sweden, The United Kingdom of Great Britain and Northern Ireland, The United States of America

Urgent need to start decarbonising shipping

Latest research on urgent need to reduce shipping emissions by Simon Bullock, James Mason &Alice Larkin of the Tyndall Centre for Climate research, published 27 October in the Climate Policy journal, shows the gap between present IMO actions and what is required to meet Paris Agreement targets for shipping.

The declaration failed to call on greater ambition in shipping.

Shipping emissions are globally equivalent to a mid sized developed nation such as Germany.

Because of long ship life lead times, we can't afford to wait.

The article concludes that significantly stronger short- and longer-term targets need to be set for the sector to be compatible with the Paris Agreement’s goals: 34% reductions on 2008 emissions levels by 2030, and zero emissions before 2050, compared with the sector’s existing target of a 50% cut in CO2 by 2050. Crucially, strengthening the target by the IMO’s strategy revision date of 2023 is imperative. The long asset lifetimes of ships and shipping infrastructure limit the speed of transition such that a delay of even a few years will dictate an untenable rate of decarbonization and increased risk of pushing the already challenging Paris goals out of reach.

A decade of no progress at @IMO_HQ  in cutting shipping emissions means the only feasible pathway remaining is the green one - with linear reductions to zero from 2023.

Key policy insights

  • There is a gap between targets set out in the IMO’s Initial Strategy and what is needed by the shipping sector to be Paris-compliant.
  • Paris-compliant targets require a 34% reduction in emissions by 2030, with zero emissions before 2050. Existing targets imply no absolute reduction in emissions to 2030, and only a 50% reduction by 2050.
  • The longer the delay in setting new targets, the steeper subsequent decarbonization trajectories become. Delay beyond 2023 would necessitate an untenably rapid transition, given long shipping asset lifetimes and global requirements for new land-side infrastructures, increasing the mitigation burden on other sectors.

COP26 in November 2021 is an opportunity for the shipping sector to signal its intent to strengthen its targets, and to implement this in its 2023 strategy revision process, at the latest.



COP 26 declaration: International Aviation Climate Ambition Coalition

Countries commit to ambitious action on international aviation emissions, including through a new global goal and promotion of cleaner fuels and technologies.

There has been much criticism of this declaration, that it fails to bring the ambition necessary for addressing aviation emissions and climate impact. Read the critiques at Blog: Civil aviation High Ambition emissions reduction at COP26? yeah nah just more greenwashing, blah, blah , blah - back to you ICAO

Stay Grounded has a Petition to the UN climate convention, the International Civil Aviation Organisation, the EU Commission, EU Parliament, and national governments: to Stop Greenwashing — Reduce Air Traffic Now!

Signatories to the declaration included: Burkina Faso, Canada, Costa Rica, Finland, France, Ireland, Japan, Kenya, Maldives, Morocco, Netherlands, New Zealand, Norway, Republic of Korea, Spain, Turkey, United Kingdom, United States of America.

Underwhelming 'Future Fuels Strategy' earns Australia's 4th Fossil award of COP26 on poor transport emissions policy

Where Australia stands on road transport climate policy Via Australia Institute
The release of the Australian Government's 'Future Fuels Strategy' on the eve of Transport Day of the UN Climate Conference, with little substance to increase Electric Vehicles takeup ensured Australia of a Fossil of the Day. This is Australia's 4th Fossil award of COP26.

The United States received the first Fossil award of the day for failing to take basic steps to halt fossil fuel production. Serbia received a third place award for giving grace to big polluters.

Victoria reduces emissions by 24.8%, on track for 45-50% reduction by 2030

Victoria achieved a 24.8 per cent emissions reduction between 2005 and 2019 and the state’s annual emissions dropped below 100 megatonnes of carbon dioxide equivalent for the first time since 1994. This are pre-pandemic 2019 figures, and it is likely emissions have further declined during the pandemic. 

The results were contained in a report tabled in the Victorian parliament .

The Andrews government has met its legislated pledge to cut emissions by 20 per cent by 2020 ahead of schedule, and is on track to meet its target of a 28 to 33 per cent reduction below 2005 levels by 2025, and 45-50 per cent by 2030.

Australian Aviation CO2 emissions equivalent to 5 coal power stations


A new website uncovers the aviation emissions associated with 1300 airports globally, covering 99 per cent of passenger flights. Twenty four of those airports are located in Australia producing carbon emissions equivalent to five coal fired power stations.

The aviation sector would have been the sixth-largest emitter of CO₂ in 2018 if it were a country, responsible for 2.5 per cent of global emissions. Up until the pandemic aviation was growing 5 per cent annually since 2013. Despite the disruption caused by the pandemic, the sector remains off-track for limiting global heating to 1.5ºC.

Aviation emissions for the website is based on data from 1300 airports from 2013, 2018, 2019. The website was a joint project by the International Council on Clean Transportation (ICCT), International Think Tank ODI, and Transport and Environment (T&E).

This is the first global attempt to focus on the infrastructure that enables and induces air travel and leads to more CO₂ emissions in future decades.

Community Panel recommends 21 actions for EV transition for Victoria to reduce Transport Emissions

Community Panel for Infrastructure Victoria on Transport Emissions. I was on this panel which had 211 Victorians (most age groups, Metro and Regional) and met online during late January to mid February 2021.

The 'Tackling Transport Emissions' Community Panel successfully worked together in a virtual environment to deliver 21 recommendations to Infrastructure Victoria using principles of a Just Transition, Equitable Access, and Shared Knowledge.

These recommendations have now been taken forward by Infrastructure Victoria to undertake a detailed technical review. This may include seeking out additional evidence or undertaking further analysis where required.

The reviewed recommendations will inform Infrastructure Victoria’s advice - to support the broader community to take up zero or low emissions vehicles sooner - to government in Victoria’s 30-year infrastructure strategy. This Strategy is planned to be released in mid-2021.

The community panel was titled 'Tackling transport emissions'. Some members felt the need to broaden the remit question's scope to include public and active transport. I was one of those people. Clearly the panel was misnamed and should have been titled 'Tackling the transition to net zero emissions by 2050 through zero emission vehicles' Of course transition to EVs is needed, but we also need to look at mode share change in behaviour for more public and active transport journeys, and urban and transport planning to change transport behaviours. Sadly this wasn't part of the remit.
