This is true! As the saying goes "amateurs study tactics, armchair generals study strategy, but professionals study logistics".
There's a lot that needs to change - but with concerted effort, it's not hard to imagine an 80 or 90% reduction in transport emissions being doable without intolerable (whatever that means in this context) financial consequences. In the UK over 80% of passenger kilometres are traveled by cars, vans and taxis. Reducing that to 10% - through a combination of better public transport, cycling facilities (especially e bikes and scooters), and increasing the cost of motoring (which could either be regarded as punitive pricing, or reducing the level of subsidy motoring receives...) would be doable, and I think in most cases increase the quality of peoples lives. There will be some trips - visiting the second home in Cornwall with the kids and dog for example - that are really hard to move to a different mode. There are others - a disabled person visiting hospital in a wheelchair, getting your book case back from Ikea - which will require some adjustment to the existing systems - but not huge - decent wheelchair access to all buses and tube stations, more bus routes, electric vans delivering your Ikea bookshelf for a reasonable cost...
What's crucial here, though, is that we can't shop our way out of this. No single individual, or winemaker, can unilaterally make the changes that are needed - in the same way that no individual would have been able to prosecute the Second World War or deliver the Marshall plan. The biggest impact that any of us can have is influencing our elected representatives to help them understand that this is important, and - crucially - our continuing to vote for them is contingent on their taking environmental issues seriously.
