The Paris Agreement provides a sustainable framework that guides global efforts for decades to come. The goal is to increase countries` climate goals over time. To promote this situation, the agreement provides for two review processes of a five-year cycle each. Anxious to „significantly reduce the risks and effects of climate change,” the agreement calls for the average increase in global temperature over this century to be well below 2 degrees Celsius, while striving to limit the increase in temperatures to 1.5 degrees. It also calls on countries to work to ensure that global greenhouse gas emissions are offset as quickly as possible and become climate neutral by the second half of this century at the latest. To achieve these targets, 186 countries responsible for more than 90% of global emissions presented carbon reduction targets known as „Planned National Contributions” (INDCs) ahead of the Paris conference. These targets set out each country`s commitments to reduce emissions (including conservation of carbon sinks) by 2025 or 2030, including overall CO2 emission reduction targets and individual commitments from some 2,250 cities and 2,025 companies. The IPCC notes that climate change is limited only by „substantial and sustainable reductions in greenhouse gas emissions.” While one can discuss the benefits of using a single global temperature threshold to present dangerous climate change, general science believes that any increase in global temperatures above 2 degrees Celsius would be an unacceptable risk, which could lead to mass extinctions, more severe droughts, and hurricanes and a nearby Arctic. Moreover, as the IPCC points out, while it is unclear to what extent global warming will cause „abrupt and irreversible changes” in the planet`s systems, the risk of crossing the threshold only increases with rising temperatures. Although developed countries are not legally required to contribute a certain amount to the mitigation and adaptation efforts of developing countries, they are encouraged to provide financial assistance and are required to report on the funding they provide or will mobilize. .
