In 2021 Bill Gates laid out a plan for eliminating greenhouse gas emissions.

Judge as of 23 August 2022. True: Bill Gates published or presented a plan for eliminating, or reaching net-zero, greenhouse gas emissions during calendar year 2021. His book 'How to Avoid a Climate Disaster', if published in 2021, would qualify, as would a comparable 2021 publication or speech setting out such a plan. Mostly true: the plan appeared in 2021, but the detail differs slightly, for example it targets net-zero rather than literal elimination, or it was released in late 2020 and promoted mainly in 2021. False: no such plan by Gates exists, or his plan was first laid out well outside 2021, for example in 2019 or 2023. A plan dated clearly outside 2021 but still before August 2022 is mostly false.

4. E4 Bill Gates: Climate challenge is formidable but solvable Stanford Global Energy Dialogues / Stanford Energy · 28 February 2021

   “Gates’ book offers a comprehensive look at emissions sources and an initial plan for meeting the Paris Agreement’s target of zero carbon emissions by 2050.”

Gates's announcement of his book How to Avoid a Climate Disaster is dated 14 February 2021 and calls it a plan for eliminating greenhouse gas emissions (E1, E2). Independent reports from late February 2021 by the Harvard Gazette (E3) and Stanford Energy (E4) describe it as his new book, and Stanford says it contains a plan for reaching zero carbon emissions by 2050. This meets the criteria's definition of true: a plan for eliminating or reaching net-zero emissions, published in 2021.
