A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.
Two possible futures: One in which no climate policies are implemented (red), and one with strong action to mitigate emissions (blue).

Moving goods by road consumes about 50% of all diesel produced; 80% of the global net increase in diesel use since 2000 comes from road freight. However, achieving climatechange targets will also require the widespread adoption of solutions that are not yet fully developed, whether in logistics or technology.
