The TTC seeks feedback on its Innovation and Sustainability Strategy. As I write this, the announcement has been posted on X/Twitter, but not on the main TTC page. Instead, it is well hidden, like so much on the TTC site, among many items on the “Riding the TTC” page under “Green Initiatives”. There is a link from the survey’s introductory page, but this is only available when launching the survey, not afterward. Within the Green Initiatives page is a link to the TTC’s 2024-2028 Draft Innovation and Sustainability Strategy, a 50-page document that puts the survey in a wider context, but which most readers are unlikely to access, let alone read.
The survey contains three sections addressing various aspects of a TTC strategy:
An “innovation pipeline”
Prioritizing climate actions
A culture of innovation and sustainability
Reading through the Draft Strategy, the overwhelming impression is of the creation of a bureaucracy within the TTC, not to mention a pervasive presence of an Innovation and Sustainability czar. Much of their work would focus on internal changes, only some of which actually address climate effects. This is not to say that innovation per se is a bad thing, but it is not defined. Moreover, it has been bundled with schemes to green the TTC that are really a separate project.
For the convenience of readers, here are the points in the survey which is open until August 16, 2024.
The “pipeline” deals largely with internal processes including a mechanism for employee suggestions, and the context is not exclusively “green”. There is also reference to unsolicited external proposals, a path exploited by an eBus proponent in early 2017. This was an eventually unsuccessful attempt to jump the queue on a bid process.
The following points are offered for ranking in the first part of the survey dealing with the “Innovation Pipeline”.
Conduct external innovation challenges (competitions to find targeted solutions) to evaluate ideas from private organizations, non-profit organizations, customers, next-generation riders, and academic partners
Conduct employee innovation challenges(competitions to find targeted solutions) to define, prioritize, and solve business problems and evaluate ideas through the TTC Innovation Pipeline
Conduct a periodic evaluation to assess the effectiveness and to optimize the process used to run innovation challenged [sic] and the TTC’s Innovation Pipeline
Conduct peer benchmarking related to new technologies, host demonstration days, and overall enhance collaboration with transit peers
Explore and adopt new technologies in an active, responsible and transparent way
Internal Intake: Create and implement an employee idea intake process with defined criteria for idea management and then evaluate ideas through the TTC Innovation Pipeline
External Intake: Create and implement an intake process for unsolicited proposals from private and not-for-profit organizations and then evaluate ideas through the TTC Innovation Pipeline
Exploring the use of Artificial Intelligence (AI) to solve problems
Implementation and use of autonomous technologies to support business tasks at the TTC (e.g., inspections, remote monitoring, etc.)
The climate section of the survey includes the following. Note that this is the only place ridership growth is mentioned. For some of the points here, one cannot help wondering why they are presented as new (e.g. waste management) when one would expect that such policies and practices would have been in place for years.
Finally, the entire list is undercut by the fiscal sustainability bullet that implies these initiatives would be self-funding from savings, or otherwise be supported by external grants. The obvious question is whether these practices, especially growing ridership, are worth doing even if they cost money.
Minimize GHG emissions through decarbonization of our fleets and installing charging infrastructure (20% zero emissions vehicles by 2025, 50% by 2030 and 100% by 2040)
Maximize TTC ridership to reduce community-wide GHG emissions by ensuring the TTC meets existing customer needs and continues to attract new customers
Encourage a reduction in GHG emissions from our employees, suppliers, and partners
Minimize TTC’s GHG emissions through greening of our facilities by transitioning away from fossil fuels and other substance that are harmful to the environment
Identify opportunities to reduce water consumption from our operations
Improve waste management practices by conducting waste audits at highest consuming sites and developing a waste reduction plan for new construction, retrofit projects, and operational practices
Specify the use of sustainable materials when purchasing products/services and in our projects, while ensuring transparency and accountability from our suppliers
Improve TTC’s green spaces to enhance the urban forest, increase biodiversity and minimize urban heat islands
Increase energy resiliency by implementing on-site renewable energy sources and advancing the use of energy storage
Identify TTC assets or operations exposed to climate crisis risks and vulnerabilities and implement adaptive measures to local extreme weather events
Maximize economic returns by seeking grant funding, capturing the savings and revenue that result from green initiatives, and self-funding the TTC’s Innovation and Sustainability Strategy
The section on a culture of innovation and sustainability includes the following:
Supporting employee innovation through a rewards and recognition program, training, and internal communications (e.g., newsletters)
Make every TTC job a sustainable job through internal sustainability communications, workshops, and sustainability awareness and training
Integrate Climate Action into the TTC by embedding a climate lens in corporate governance, capital projects (where applicable), and info knowledge sharing
Seek advice and guidance from employees and customers at the early stages of the Strategy to ensure the work considers safety, accessibility, diversity, equity and inclusion
Release annual innovation and sustainability progress reporting
Annual reporting and performance at the TTC depend both on the adoption of meaningful and measurable goals, and on honest reporting. The CEO’s report contains many metrics, as I have discussed before, that are simplistic and potentially misleading about actual TTC achievements. For example, it would be easy to achieve a high percentage of sustainability goals if many of these are small-scale, easily achieved changes (including those already committed and underway) while leaving the harder work of building ridership as a single bullet.
If you have read this far, your brain is likely over-full of management-speak and the sense of over-reach relative to a green agenda. It is a bizarre public survey considering how many points deal with internal matters that are only tangentially related to the environment.
A striking point about the survey is that the largest potential for greening the city as a whole, and not just the TTC, lies in diverting trips from autos to transit. This receives only passing mention in the survey, although the Draft Strategy document does cite the City’s NZ2050 goals which propose a massive increase in transit service. That goal has not been endorsed, let alone funded, by Council.
The Draft Strategy includes a chart showing the potential increase in the bus fleet to 2050.
This is part of a wider proposal:
As part of the technical work, one scenario was modelled for the transportation network to illustrate a pathway to achieving community-wide, net zero GHG emissions. This included service frequency of bus, streetcar and subway by 70%, 50% and a maximum three minutes headway off-peak, respectively, along with a number of other policy and behavioural changes. These service increases are beyond our current capital and operating plans. [Draft Strategy at p. 27]
TTC riders might well ask just how much effort the system makes today in attracting ridership when all three fleets – bus, streetcar, and subway – include far more vehicles than needed for current service plus maintenance spares. The surplus sits in garages and carhouses for want of operating funds to hire operators to drive and mechanics to maintain them.
At the end of the survey, respondents are asked to prioritize initiatives from the list below. Note that “encouraging more transit use” is only part of one item.
Build climate resilience at the TTC (e.g., implementing adaptive measures to risks)
Foster a culture of innovation at the TTC
Be climate and fiscally responsible to maximize economic returns
Scout for emerging technologies and solutions
Protect our natural ecosystem (e.g., restoring ecological green space performance and reducing light pollution)
Build an open intake process for innovative ideas (e.g., employees)
Eliminate GHG emissions (e.g., fleet, facilities, encouraging more transit use)
Identify and solve TTC problems with innovation challenges
Commit to ongoing consultation to ensure the work of Innovation and Sustainability at the TTC is informed by customers and employees through safety, accessibility, diversity, equity and inclusion considerations
Reduce the TTC’s consumption of water
Drive transparency and accountability of innovation and sustainability initiatives
Foster a culture of sustainability at the TTC
Searching the Draft Strategy for how the TTC might encourage more transit use, we find:
Encourage a modal shift by implementing the actions outlined in the 5-Year Service and Customer Experience Action Plan. [Draft Strategy at p. 47]
However, the 5-Year Service and Customer Experience Action Plan foresees only a modest growth in service with ridership remaining below pre-pandemic levels overall in the near future. That Plan is tethered by fiscal realities, a lack of advocacy for what the TTC might do, and the resources needed to achieve real improvement.
The “Customer Experience” part of that plan has included various schemes to add creature comforts to the system, but not an increase in service quality. This will require a combination of more transit vehicles on the street and much better service management to ensure reliability.
At the end of the day, the Draft Strategy and its packaging under the green banner could be little more than a make-work project to give the impression of progress. Meanwhile, riders waiting for their buses and streetcars will see few changes.
Ooh, ooh! I haven’t even read this but saw the greenwashing headline and have an idea:
String wires above bus routes and replace Diesel buses with electric buses!! This ground-breaking idea has never before been tried – Toronto could be a *leader*!!!
Looks like someone senior at the TTC had “solicit input on sustainability strategy” in their 2024 Goal Plan deliverables and is looking to check that box off with minimal effort.
To be fair to the TTC, in the Draft report they absolutely acknowledge that “Scope 4” emissions (the avoided emissions they enable by reducing private vehicle use) is important, they just haven’t yet gotten around to quantifying it. This to me is the big gap, to maximize their “greenness” or even balance it as part of a broader set of objectives, they need to understand the ratio of how their own emissions (bus tailpipe but also electricity use) compare to what they’re saving. Once you have this data in hand, in theory you can start to model x% ridership increase leads to y% vehicle mile reductions and optimize in that way, trading off a dollar in eBuses vs a dollar in increased conventional service.
The broader point that needs to be reckoned with is that although transit is obviously better than single-occupancy internal combustion engine cars, if we (the TTC, the City, Society, whatever) are actually serious about climate mitigation in line with science-based temperature scenarios, there’s simply not much room for a jurisdiction like Toronto to put more diesel buses on the road, except in the perhaps the highest ridership corridors (where ironically it becomes more efficient to convert to other modes anyways). That’s not to say that we need to go all electric tomorrow, but simply that if the TTC actually wants to do it’s part to achieve a 1.5 degree scenario, we really do need to scale up the electric buses in the fleet.
Steve: TTC’s fleet of diesel buses is dwindling with replacement hybrids coming in now, and a large order of eBuses to follow. The budgetary challenge is that there isn’t enough headroom to actually operate the roughly 2,150 buses in the fleet regardless of their technology.
Quite unbelievable that they missed the mark and overreached only to forget about their whole purpose of getting more riders…. wow
Well, yeah. But there is nothing wrong with wanting to emit fewer humanity-ending pollution.
Hey, Bossman Steve … you got a bus roster from, say, 1985, so we could see what percentage of the fleet was emission-free compared to now? I know the Commission has a few pretend electric buses, but I am curious how many ETBs they had before they developed their wire allergy. What was the peak era for ETBs, anyway?
Steve: For info on the ETB fleet, see this article on Transit Toronto’s site.
I don’t have a bus roster from 1985, but you can get a sense of the relative usage of the fleets (which is actually more important than the vehicle count) from a 1985 service summary (look at the last page). Note that many old summaries are available on my site. They include fleet rosters (down at the end) from 2005 onward.
And yes, you in the back, it takes GHGs to make electricity, but it’s way simpler to control those at one plant versus a Diesel plant on every vehicle.
1. Has any planning been done to see what expansion needs to be done to our electric generating requirements and our electric transmission and distribution grid? I will bet it is massive.
2. Has there been any comparison of the cost to put in battery charging stations in the garage and their costs with stringing overhead and its maintenance?
3. Has there been any life cycle comparison for the total GHG emissions from the mining of the Lithium and rare earth metals required for the batteries up to the building, running and eventual disposition of the retired buses and their batteries? We need to consider the entire picture, not just local GHG.
4. What effect will running a full eV fleet have on the number of busses required? Will there be end of line charging stations? these require space for the batteries and the overhead charging station that other vehicles cannot get under.
5. What is the length of time required to recharge a bus? \the lower the re-charge time the higher the power required. You may read about these wonderful new batteries that can re-charge in 6 minutes but they never talk about the amount of power required. If you want to put 100 kWh (kilo watt hours) into a battery at a rate of 10 kW per hour that takes 10 hours. (10 kw/h times 10 hours = 100 kW.) If you want to charge it in 6 minutes, 1/10 of an hour, you need 1,000 kW capacity. (1,000 kW per hour times 1/10 of an hour = 100 kW.) Life is a series of trade offs and we have to make wise choices. A new home has a 250 Volt feed at 200 Amp max capacity for a maximum power rating of 50,000 Watts or 50 kW, a far cry from 1,000 kW. For you electrical engineers I am avoiding complex power as this topic is complex enough.
6. Where do you get the extra electrical energy from? People talk about renewables such as solar and wind but these have limitations as to when they can generate power and they tend to bring out the NIMBYs. The two major methods of energy storage are batteries or pumped water storage. (Pump water up a hill into a large pond when you have excess capacity and let it run down to generate electricity.) There is a third which I believe was tried near Toronto that involved pumping air into large bags under the water and then letting it out to drive generators when needed. I don’t know how well this worked. They all have their backers and their detractors. Check out YouTube for both sides, compare the pros and cons, you might even find the odd one that does strictly a fair comparison.
Steve: Reading between the lines, the TTC seems to be moving away from only having garage-based charging and allowing for top ups enroute at terminals. The implications of this for added layovers, not to mention space, have not been explored.
The size of generation capacity and the feeder system needed lies with Hydro who are doing the electrical supply work, and they are counting on onsite storage with batteries to spread out the period when they will draw from the network. All the same it’s a lot of power that will be needed to recharge the fleet overnight.
There is no estimate of the overhead (cost, not wires) of extra garage trips to recharge, or of dwell time for recharging at terminals.
Bluntly, when this project started, I don’t think that the “innovations” brains trust at TTC had much sense of this and they were simply getting onto the green bandwagon. They didn’t even know about work Vancouver had already done on the subject. That was back in 2017 when BYD was flogging their wares hoping for a soul source contract.
I think it’s good that the TTC now has the analytical brainpower to do proper green metrics and evaluations. I think there may be diminishing returns of stuff they can analyze though, so it’s nice that they can be retasked to analyze general wastage and inefficiencies in the TTC. Maybe they could also be tasked to look at scheduling or infrastructure to improve headways, and other analytical tasks.
Steve: I have hopes that with Leary’s departure, we might see some new senior staff who actually do honest, open analysis, not self-serving puffery, but that depends on the TTC acknowledging its failings and working for real, not superficial, improvement.
While theoretically, transit is inherently ‘better’ than private fossil-fuelled mobilities, there is a degree of sustain-the-bull, aggravated by being at the tail end of a whip of, say, the Premier/Dougtator, who is ‘carservative’ and interested in pyrotization as a climate policy and ensuring evermore concrete usage, or that’s the feel. And the City has been obliging well before Mr. Ford in ‘caronic’ denial, including concrete usages, which are NOT counted in EA projects, but should be.
We really need honesty in the GHG accounts, including air travel GHGs as well as the forest fire carbon outputs, c. 3B tonnes, uncounted in our country profile, but it really does make for an ’emergency’ where we should react by simply banning cars in some defined areas, and think of ‘roadical’ fixes like busways, even Jarvis-style busways, on both Gardiner and DVP, as we need sub-regional express, not sub-par excess of bunchings etc.
I’ll re-read far more closely again soon; but while it does smell badly like greenwashing, there’s also a LOT of company, if not ‘leadership’.
Steve: The greenwashing is particularly evident in the number of issues in the “Plan” which have nothing to do with environmental improvement, not to mention the almost invisible reference to getting people out of cars. The whole document is a make-work project to give the impression of useful enterprise while not actually improving transit, let alone its environmental contribution beyond the full electrification of the bus fleet, a project that is already underway without an entirely new “innovation” organization to drive it.
Good news: High-rise development will finally be coming to Pape Ave after Metrolinx expropriates houses to sell to developers. The subway cannot be justified with those low density single family houses, high density high-rise development is needed on Pape Ave to justify the subway.
Steve: First, there will still be many block of low rise, and originally Metrolinx told the people in the block they are taking that their property would not be required. Second, there is a hugs amount of high rise planned for the lands around Gerrard and Pape Stations. This is just a cock up by Metrolinx engineering.
Ooh, ooh! I haven’t even read this but saw the greenwashing headline and have an idea:
String wires above bus routes and replace Diesel buses with electric buses!! This ground-breaking idea has never before been tried – Toronto could be a *leader*!!!
