Learn why Architecture 2030 founder and CEO Edward Mazria is optimistic that the U.S. can target a significant reduction in carbon emissions in the country’s updated Nationally Determined Contributions.
In the Feb. 26 release of the interim United Nations Framework Convention on Climate Change report, Secretary-General António Guterres boldly declared 2021 the “make or break year” for the planet. The report found the 2030 Nationally Determined Contributions (NDCs) emissions-reduction pledges of 75 countries to be wholly inadequate. Global greenhouse gas emissions would only be cut by about 1%, far short of the 65% cut in carbon emissions from January 2020 levels needed by 2030 to have a 67% probability of limiting global warming to 1.5°C above pre-industrial levels and to meet the goals of the 2015 Paris Agreement.
The science and global carbon budget for limiting warming to 1.5°C are clear. The remaining budget at the beginning of 2020 was 340 gigatons of carbon dioxide, which means that if the world achieves a 65% reduction of CO₂ emissions by 2030 and zero emissions by 2040, we can expect warming to be kept at about 1.5°C.
The time to act is now. The most significant climate event since the 2015 Paris Agreement—when all parties agreed to pursue efforts to limit the global temperature increase to 1.5°C—will take place this November. At the 2021 U.N. Climate Change Conference (COP26), countries must submit their updated 2030 NDCs. To date, only the European Union, the United Kingdom, and Denmark have committed to significant 2030 emissions reductions from 1990 levels: 55%, 68%, and 70%, respectively. Much, much more is needed to reach the critical goals.
