NASA: Alaska Shows No Signs of Rising Arctic Methane

10. And you point to G20 promises?

One thing human beings are very good at is playing with words.

When the question is parsed out in terms of "meaningful actions being taken to reduce the amount of CO2 being put into the atmosphere" rather than "promises being made to reduce the rate of increase of emissions some time in the future", the correct answer is "None".

The only things that have been demonstrated to reduce the amount of CO2 emissions are economic recession or social collapse. That effect can be seen across the ex-Soviet bloc countries after the USSR collapsed, or the world-wide recession in 2008-2009. Nothing else has been shown to work. That's because CO2 emissions are inherently tied to economic activity. But triggering an economic collapse isn't exactly an action anyone would undertake to reduce emissions, is it?
