Diesel Buses Purchase not the Better Way for TTC
by Matt Tomich (Toronto Star) Toronto is currently eyeing a major investment in diesel buses, which would derail progress toward its emission reduction goals and pull a major punch in the fight against climate change.
The Toronto Transit Commission (TTC), the city agency with the highest vehicle fuel consumption and greenhouse gas (GHG) emissions, plans to spend $934 million to buy more than 1,000 new buses and revitalize about 700 others — 729 are slated be diesels, and 254 to be second-generation diesel hybrids.
Instead of diesels, the TTC could buy natural gas buses equipped with “near zero” engines and fuel them with renewable natural gas (RNG), also known as biomethane. Compared to the most advanced diesels, these buses emit a tenth of the smog-forming, asthma-triggering and health-damaging pollutants, while running them on RNG deeply slashes GHG emissions.

Excerpts from Toronto Star: There is very little discernible difference when it comes to emission reduction when replacing older buses with either new diesel or RNG models. In fact, the RNG option may cost the TTC much more, given the relatively higher price of an RNG bus and the much higher price for installing refuelling infrastructure.
If the debate is more about sustainability than about emission reductions, natural gas isn’t the only fuel with a renewable counterpart. TTC should look to renewable diesel fuel. Businesses and municipalities across California have been using renewable diesel fuel capable of reducing greenhouse gas emissions by upwards of 80 per cent. READ MORE
