group of academics and activists introduced "a green stimulus to rebuild our economy" in March 2020. The menu of policies targeted eight fields, housing and civic infrastructure, transportation, labour and green manufacturing, energy generation, food and agriculture, environment and green infrastructure, innovation policy, and foreign policy. Its requested funding level was set at 4% of the US GDP, or around $850 billion a year, until the dual achievement of full decarbonisation and an unemployment rate below 3.5%. In the UK, the government proposed "a green and resilient recovery," and announced £3 billion in funding for building renovations in July. By contrast, in early July, an academic and think tank group proposed a "Green Recovery Act" that targeted nine fields: transport, energy generation, agriculture, fossil fuels, local government, international agreement, finance and corporate governance, employment, and investment. This established duties on all public bodies and regulators to end use of fossil fuels "as fast as technologically practicable," with strict exceptions if absent technical alternatives. In June 2020, the German government pledged a green recovery with funding of €40 billion (£36 billion or US$45 billion) as part of a €130 billion recovery package. In July 2020, the European Council agreed to a recovery fund of €750 billion, branded Next Generation EU (NGEU). An overall climate target of 30% will apply to the total amount of expenditure from the NGEU in compliance with the Paris climate agreement. In February 2021, commentators such as the Council on Foreign Relations noted that other major economies such as China, India, and the European Union had begun "implementing some of the policies envisioned by the Green New Deal." Over spring 2021, US President Biden introduced his American Jobs Plan and American Families Plan, which incorporated green recovery principles including investments in carbon capture and storage, clean energy, and a Civilian Climate Corps similar to the Depression-era Civilian Conservation Corps. Progressives criticised the plans as not ambitious enough. A July 2021 update to the World Scientists' Warning to Humanity found the 17% of COVID-19 recovery investments funds that had reportedly been allocated to a green recovery as of March 2021 to be insufficient. They warned that climate policies should be part of COVID-19 recovery. They demanded that plans address root causes and that immediate, drastic reductions in greenhouse gases be prioritised. According to a 2021 analysis by the Overseas Development Institute, China could do more to support a
