I can talk about them a little, although I'm not an expert.
One forward-thinking model is California's Low Carbon Fuel Standard. California has a timeline for greenhouse gas reduction, about 2% or 3% per year through 2030. They have a penalty for non-compliance of $200 per ton of CO2 equivalent. It was one of the first strict mandatory models, and it has spurred innovation tremendously. The petrochemical industry has accepted the model and is actively participating in it by seeking solutions.
Another very interesting model is the one governing all of Europe, the Renewable Energy Directive, and it has been renewed until 2030. They are already working on a renewal to 2040.
In our sector, the trouble lies in what is called the technological risk of innovation. We understand that, but to fund projects, we face a risk in terms of the market if regulations are not secure or strict. This leads to trouble with respect to financing. You can't finance projects in the traditional way. It takes a regulatory plan that goes beyond 2030 and into the future.
