With the Paris Agreement, countries committed to collectively limit global warming to well below 2 °C and pursue efforts to limit warming to 1.5 °C above preindustrial levels. However, there is currently no commonly agreed effort-sharing mechanism to determine the contribution of each country. The Pledged Warming Map provides an assessment of global warming when all countries follow the ambition of a given one, reconciling the bottom-up architecture of the Paris Agreement with its top-down warming threshold.
