IMO closer to agreement on CO2 regulation, but obstacles remain
Global shipping has for decades avoided necessary climate regulation, despite being responsible for about 3% of global greenhouse gas emissions, equivalent to Japan's emissions. As around 90% of global trade takes place by sea, the sector's emissions are expected to continue to rise unless specific measures are taken.
At the beginning of October, delegates from over a hundred countries met in London for an important meeting of the International Maritime Organization (IMO). The aim was to find a common agreement on how to decarbonise international shipping and put the sector on track to reach net-zero emissions by 2050, as expressed in the IMO's Greenhouse Gas Strategy. Denmark, supported by its strong maritime industry, played an important role in trying to negotiate an ambitious but politically sustainable agreement home.
Bridging the gap between fossil fuels and e-fuels
Much attention was devoted to temporary measures that can effectively bridge the price gap between conventional fossil marine fuels and sustainable renewable electricity-based fuels, so-called e-fuels. The need for this is particularly clear in light of Ørsted's announcement to abandon its FlagshipONE e-methanol project in Sweden, even though the project had previously received a final investment decision.
Lack of demand and slow market progress have been cited as the main reasons for the termination. At the same time, shipping companies such as Maersk invest in dual-fuel ships, but find it challenging to secure the necessary quantities of e-methanol at a competitive price.
The IMO and its Member States thus have a unique opportunity to help solve this chicken-and-egg problem by creating a stable and predictable regulatory environment that can ensure demand for clean e-fuels in the years to come. A combination of regulations and financial incentives should provide the necessary boost.
Combination of economic and technical measures
Firstly, a binding sub-target for sustainable e-fuels and an ambitious but realistic target to reduce the carbon intensity of maritime fuels will both contribute to reducing emissions and guarantee a minimum uptake of e-fuels by 2030. In addition, a reward factor for use of sustainable e-fuels when calculating the carbon intensity of ships further encourage early adopters.
Second, a global CO2 tax on emitting fuels will help offset costs and make sustainable fuels more competitive. Its revenues can then be used to at least partially support least developed countries and small island states in their decarbonisation efforts, in line with the principle of just transition. In addition, financial incentives for e-fuel producers will help kick-start the production of e-fuels by providing targeted subsidies to reduce the price gap with fossil fuels.
Last but not least, establishing a strict definition of zero and near-zero emission fuels that takes into account their full life cycle is necessary to exclusively promote fuels with the potential for full decarbonisation. This would ensure limited uptake of transition fuels, which may appeal in the short term, but whose long term impact would cause more harm than good. Examples of these are biofuels, which carry significant environmental and biodiversity risks, or LNG, which releases methane, which contributes to global warming.
The countries are getting closer, but more needs to be done
There was a sense of urgency at the IMO meeting, particularly from small island states that are already experiencing the catastrophic effects of climate change. However, due to different views on several issues, in particular the universal CO2 tax, no agreement has been reached. The word that resonated most was "convergence". The list of options on the table is narrowed and there is a better understanding of where the proponents of the various measures are coming from.
Much attention has been paid to the effects of the universal CO2 tax on the most vulnerable states. While several studies have already confirmed that a higher tax combined with a generous fund financed by the revenue would have a net positive impact on LDCs and their GDP, attention has now turned to food security. Although this is a critical issue to address, it is important to remember that food security is primarily threatened by climate change as well as deforestation and unsustainable production and consumption of biofuels, which are touted by some countries as the solution to decarbonizing shipping.
More work must be done before next spring, when the measures must be formally approved. It is in Denmark's interest as a major maritime nation as well as a country with high potential in green energy and e-fuel production to strive for a global agreement that will not only benefit its economy, but also its ailing marine environment.
