The transport sector accounts for 24% of global energy related CO2 emissions and is the fastest growing emission source. Yet, a clear-cut transformation path is missing. To close this gap @TUMInitiative and @UTSEngage developed a robust scenario: the #TUMIOutlook 1.5˚C. ➡️🧵1/9
Only urgent climate action today will limit global warming: We have 99 months from 2021 to 2030 to take significant action. The TUMI Transport Outlook 1.5˚C provides concrete pathways of action towards a transport sector in line with the Paris Agreement.
For the first time we map out a global roadmap to a transport sector in line with the 1.5˚ C threshold. The recommendations build around 3 pillars:
1 Avoiding the need to travel 2. Shifting to more efficient modes of transport 3. Improving efficiency through vehicle technology
➡️To remain within 1.5°C we need to phase out sales of internal combustion engine vehicles by 2030.
➡️Electric mobility 🔋⚡powered by renewable energy is the future. We can’t achieve global decarbonization of transport without it.
🚶♀️🚲Investment in walking and cycling infrastructure is needed. Cities from Amsterdam to Bogota show how to curb passenger vehicle usage & increase livability.
➡️50% active mobility modal shift should be targeted for 2030.
➡️Double public transport capacity by 2030 👇
🚌🚇🚋Public Transport is the backbone of low-carbon transportation. To leverage its potential, the capacity of public transport needs to be doubled, with attention paid to service quality and convenience.
➡️By 2030 at least 70% of rail needs to be electrified. The 1.5°C pathway assumes a 30% shift of freight transported via trucks to rail. Complete global diesel locomotive phase out is assumed by 2050. Full electrification via overhead / battery electric trains needs to be pursued
➡️Prioritize electricity⚡as the primary fuel for transport. 👇
No matter the scenario, to limit greenhouse gas emissions, all transport fuels need to be carbon free by 2050. Renewables in transport are the only way to meet the 1.5°C pathway.
German Railway begins construction of overhead wire islands.
➡️ The electrification of railway lines is complex and expensive. Deutsche Bahn is therefore starting to equip only shorter sections with overhead wires.
In this case the railway lines are not fully equipped with overhead wires, but only partially.
Battery trains are then used on the routes, which can charge their batteries on the electrified parts of the route and use the stored energy to go on sections without overhead wires.
Planning effort and costs of such islands should be significantly lower than the electrification of entire routes.
This @nytimes feature gained a lot of attention. It’s principal assessment is spot on: We are making progress towards climate action, but will likely fail 1.5C. I believe it also offers a good account of the messy nature of international politics 🧵nytimes.com/interactive/20…
The climate issue is inherently complex, touching basically every field of policy making and transcending government tiers and borders. The discussion on climate is made in many arenas and it’s only logical that we see progress in some, yet regression in others.
This makes it hard to assess where we overall stand on the issue, even for many people working in the field, and it makes reports from @IPCC_CH and the like even more import.
I am more positive right now about the state of climate action than at many times in the last decade..
This small hospital 🏥 in Bangladesh 🇧🇩 has just been named best new building in the world @RIBA.
🤔 WHY?! ➡️ it’s a lesson in climate resilient architecture.
Here is what architects and builders worldwide can learn from this building 👇🧵
“Rising sea levels caused by the climate crisis have meant that the surrounding landscape of grain fields has been transformed into shrimp fisheries, while the groundwater has become too saline to use for most purposes.”
“In the rainy season, locals do everything they can to collect and store every last drop of fresh water.”
“The canal zigzags its way through the site, collecting valuable rainwater and helping to cool the surrounding courtyards during the sweltering summer months.”
Cities around the world are abolishing parking requirements🚗🅿️.
Toronto 🇨🇦 is just the latest.
But why?!👇
Parking requirements - a thread🧵
Firstly, parking requirements are random. They are neither based in research, nor data. Parking minimums are random government mandates to allocate a proportion of space on privately owned land for cars - no matter if necessary or not.
The building 🏢 below ? All lower floors are parking.
Why? Because.
Cities don't survey existing parking to see if their requirements are rational, and they often are not.
