—and I have limited time.
There are a couple of things. One is to emphasize the importance of the economic potential. The IEA— the International Energy Agency—and the ETP, which is the technology forecast, are among the subjects of the discussion today. They expect a $4.5 trillion cumulative investment by 2050 just in hybrid vehicles. That excludes biofuels and other areas. Under a constrained-carbon scenario, that would almost double, so we're talking about a very large investment potential. It would include domestic investment, but it's also the global market, which means it's a very important agenda.
From a policy perspective, and I'll take from some of the questions that have been posed to us this morning, there is a traditional view relative to transportation that there may be regulations that act as barriers to innovation. I think I've heard that in some of the questions.
However, in the context of innovation, the multiple fuels and multiple vehicle technologies that have to merge, and the challenges of bringing those to market—you see low-carbon fuel standards, for instance, and some jurisdictions trying to force that investment—the challenge for policy-makers is to manage the barriers that regulations create, but it's also enabling regulation that will allow those commercialization opportunities to happen.
For example, we've heard through this process that Fleet Advantage has created that one of the challenges is charging connections or refuelling connections. Canada has been a global leader on standardization in the ICT sector; this is a problem or a challenge within fuels. You can't have each manufacturer having its own connector, because how would you possibly fuel these vehicles, if one assumes the fuel was available?
Government will ultimately play a role in those situations, with the advice of industry, so I think when you couple the issues of transportation and carbon emissions with the economic viability and the availability of fuels and technology platforms, enabling regulation and enabling policy will be key. That would be the advice: to remove barriers where you can, but to listen for where that enabling technology can not only help with domestic investment and implementation but also help to take those technology platforms to other markets globally.
