Lots of goals are debated about at the climate summit. What should each country's emission target be? Then, unfortunately, life gets in the way. Seems like the goals are usually not attained. Our way of life, itself, does need changes.
Setting the goals gets lots of focus, but it may not matter that much anyway, unless the goals are followed. It may just be a waste of jet fuel getting people to the conference and another excuse for the masses to say their leaders are hypocritical with their own carbon footprints.
