Shipping, aviation and road transport will face vast changes in fuels, electrification, and infrastructure over the next three decades. DNV has quantified this consistently in our annual Energy Transition Outlook , and our Transport in Transition is a deep-dive into availability, technology development, costs, policy drivers, and likely uptake of sustainable energy sources in transport sectors through to 2050.
Shipping, aviation and road transport today account for almost 25% of overall emissions. We forecast this to rise to 30% by 2050 although total emissions from transport almost halve. The central difficulty for transport is that much of it will remain fuel-dependent, even though 78% of all road transport will be electric by 2050.
