Environmental groups have become critical of the IEA's 450 Scenario (created to align with the 2009 Copenhagen Accord), contending that it does not align with up-to-date climate science, nor is it consistent with the Paris climate agreement that aspires to limit global warming to 1.5 degrees Celsius. In March 2017, the IEA (along with IRENA) published a report that considers a safer climate scenario than their current 450S. This scenario offers improved chances of limiting global warming to less than two degrees, but – according to research organization Oil Change International – still falls short of adequately addressing climate science and the decarbonization required to reach agreed upon global climate limits. The IEA has stopped updating this safer climate scenario.
