We look at this from the point of view of scenarios: Looking forward over decades, how will the world's energy system transition? It's pretty hard to pick a year at which you will get peak oil, but there definitely will be a time in the next maybe 10 or 20 years when we'll see peak oil.
In the interim, though, recognizing that the demand for oil will still be sustained because it will be a long tail of reduced demand over a long time, how can we meet our commitments for the 1.5°C limit to global warming that we need to, as a society, work towards? That's where the concept of really focusing on reducing emissions now, while we transition to new energy sources, is something that I think we can work in tandem.
