A Cowboy Earth Day Climate Summit?

After a 4 year 'absence', the US is attempting to regain the moral high ground in the fight against climate change (https://www.theguardian.com/us-news/2021/apr/22/us-emissions-climate-crisis-2030-biden). The US 'offer' is that they will achieve a 50-52% reduction (compared to 2005 figures) in 'greenhouse gas' emissions by 2030. They hope this will restore their international credibility, as well as providing encouragement for other countries to follow suit. Indeed, the Americans claim that Argentina, Canada and Japan have already made offers in 'the same ball park'. Most of the focus of US emissions reductions seems, however, to fall on electricity generation (intended to rapidly cease generating carbon dioxide). The US will also encourage the use of electric vehicles but will not yet phase out all petrol/diesel cars. There has not yet, however, been much reference to methane. Methane is also a 'greenhouse gas'. It is, however, much more potent than carbon dioxide. Methane is mostly expelled in the burps and farts of beef and dairy cattle. The US maintains enormous herds of these animals. Americans may also have to think about their diets, if they want to be taken seriously in the 'war' against climate change. Having said that, it is good news that the US is actually 'stepping up to the plate', rather than denying we have a problem.
