Rowing Back Via Covid-19?

It's a bit tough on the Japanese, given the impact of Covid-19 on their Olympics, but their new plan for 'greenhouse gas' emissions targets have been roundly condemned as 'wholly inadequate' (https://www.theguardian.com/environment/2020/mar/30/campaigners-attack-japan-shameful-climate-plans-release). The Japanese were one of the first major countries (they are the 5th largest polluter) to publish their plan in advance of the proposed Glasgow meeting. Broadly speaking, their aspirations don't seem to have improved over what they agreed to in 2013 in Paris (although it is now recognised that this would have been inadequate to limit the increases in the global temperature to a 'safe' level). A number of authorities appear worried that Covid-19 pandemic will be used by countries to 'water down' their emissions targets
