By William Todts, freight and climate directorWHAT WE LEARNED IN 2016: “So what did you learn in 2016? And could you write a blog about it?" asked our communications officer.Silence. My God, where do I start, I thought. First Brexit, then Trump, and before all that there were people bombed on the metro in my hometown. What a year! But I can't write a doom and gloom Christmas blog.Then somehow I started thinking about this one thing that had really surprised me. A year ago I was campaigning to get the EU to introduce truck CO2 standards and, frankly, things weren’t looking great. Yes, there had been the Paris agreement, but still the odds were stacked against us. The Commission just didn't want to budge and the truck industry seemed all-powerful.
