In 2015, 196 global parties signed the Paris Agreement which agreed to limit the global temperature rise to well below 2ºC, but a recent UN report indicates that more aggressive measures are required to meet this goal. In 2022, Earth’s greenhouse gas concentration reached an all time high, approximately 50% higher than pre-industrial levels. Preventing global warming from exceeding 1.5ºC and reaching net zero emissions by 2050 will require nearly $4 trillion of annual investments in clean energy and infrastucture starting in 2030, according to the International Energy Agency (IEA).
