Net Zero

In the context of climate change and greenhouse gas (GHG) emissions, the goal of achieving a global balance between the volumes of GHGs produced and the GHGs removed from the atmosphere to meet the goals of the Paris Agreement to:
  • Ensure the rise in global mean temperatures is kept well below 2 degrees Celsius above pre-industrial levels.
  • Aim to limit global warming to 1.5 degrees Celsius.
Net zero may be achieved by, among other things:
  • Decarbonizing the electricity sector. This requires increasing the percentage of US energy generation produced from renewable sources (for example, wind and solar) and zero-emission sources (for example, nuclear energy).
  • Increasing energy efficiency, including constructing more green buildings.
  • Increasing the percentage of electric or zero-emission vehicles on the roads.
  • Reducing the amount of methane, carbon dioxide, and volatile organic compounds released into the atmosphere.
  • Using carbon removal technologies, including carbon capture and sequestration.
The concept of net zero is often conflated with carbon neutrality and these terms are often used interchangeably. But some commentators differentiate these terms owing to their different approaches on issues such as the emissions that the targets cover, the ambition of the targets as regards the level of global warming that should be permitted, and when carbon offsets are permitted.
As part of President Biden's Leaders' Summit on Climate that was held in April 2021, the Department of Energy (DOE), along with other governments, announced six new initiatives that will:
  • Expand international cooperation around tackling the climate crisis.
  • Boost clean energy innovation.
  • Advance an equitable transition to a net zero future.
These efforts are intended to meet the Biden Administration's ambitious domestic goals of 100% clean electricity by 2035 and net zero carbon emissions by 2050, while creating millions of good-paying jobs across the nation. For more information on these goals and the initiatives and policies that have been proposed or implemented to achieve them, see Practice Notes, Biden Administration Energy and Climate Change Policies and Regulations: 2022 Tracker and Biden Administration Energy and Climate Change Policies and Regulations: 2021 Tracker.
One of the six initiatives that were announced is the formation of the Net Zero Producers Forum (NPF), a cooperative forum consisting of the DOE and energy ministries from Canada, Norway, Qatar, and Saudi Arabia, which collectively represent 40% of global oil and gas production. The NPF will create pragmatic net zero strategies, including:
  • Methane abatement.
  • Advancing the circular carbon economy approach.
  • Development and deployment of clean-energy and carbon capture and storage technologies.
  • Diversification from reliance on hydrocarbon revenues.
  • Other measures in line with each country's national circumstances.
