On April 22-23, 2021 the White House hosted a virtual summit bringing together forty world leaders with the aim to set new, firmer targets aimed at reducing carbon emissions and transitioning the global economy to a cleaner, more sustainable model [1]. The Biden Summit was preceded by announcements from the United Kingdom and the European Union setting forth new goals that would see both reduce their emissions by 78% (on 1990 levels by 2035) and 55% (on 1990 levels by 2030), respectively.
On the first day of the summit, the Biden-Harris administration unveiled their plans to reduce United States (U.S.) emissions between 50 to 52% below 2005 levels by 2030 – a 12-14% increase of what President Obama had committed to at the 2015 Paris Agreement [2]. Contrary to other nations, the U.S. baseline target is based on 2005, the year where the nation’s emissions peaked at over 6 gigatonnes. Following on from this announcement, U.S. became one of eight countries worldwide to publish their updated (second) Nationally Determined Contribution (NDC) which outlined how they expect to meet their targets [3]. This is compared to 192 countries that have submitted their first NDC. Among the goals set out by President Biden include [2]:
- 100% of America’s energy to be carbon-free by 2035;
- Use of tax credits to accelerate implementation of wind and solar energy; and
- $174 billion to be put into the electric vehicle infrastructure.
China and India made announcements of their own, committing to varying levels of decarbonisation as President Biden called for a concerted, global push by the world’s largest economies to reduce emissions. While the U.S.’ re-entry into the Paris Agreement and new targets are no doubt impressive, scientists and experts warn that their – like most major nations’ – commitments are still short of what is needed to limit global warming to a 1.5°C increase [4]. According to the Climate Action Tracker, the U.S.’ new goals remain 5-10% points short of falling in line with that target [2].
After what has been an important summit, all eyes are now set on the looming COP26 climate conference in Glasgow in November.
