Key learning objectives:

  • Understand how net zero has evolved as well as the specific phases of implementation

  • Understand the pillars of integrity in setting credible net zero targets

  • Outline the convergence on standards for net zero and emerging frameworks

Overview:

Net zero targets provide a framework for reducing greenhouse gas emissions and addressing climate change. Credible commitments depend on clear pledges, measurable plans and accountability, ensuring that targets translate into meaningful action. Understanding how net zero has evolved and the principles behind robust target-setting helps organisations assess the integrity of their climate commitments.

Summary
How has net zero evolved and what are the specific phases of implementation?
Net zero transitioned from a scientific concept to a societal governing principle in less than a decade. This evolution is split into three phases:
  • Phase One (2008–2015): policy acceptance of net zero as balancing human emissions with natural removals.
  • Phase Two (2015–2022): the surge in pledges by countries, regions, and companies to achieve net zero.
  • Phase Three (current): focus on integrity and implementation, where delivering on net zero commitments is paramount.

What are the pillars of integrity in setting credible net zero targets?
Credible net zero targets rest on several core principles:
  • Publicly pledge net zero aligned with your responsibility, with interim milestones.
  • Develop a specific and measurable plan covering all emissions, including scope 3 or value chain.
  • Begin emission reductions immediately, as CO2 lingers in the atmosphere for a century.
  • Transparently publish progress and verify reductions through independent third parties.
  • Align policies and lobbying efforts with climate goals.
  • Clearly disclose the use and quality of carbon credits, limiting their use before 2030.

How do standards and frameworks support accountability for net zero targets?
Accountability is supported by converging frameworks and initiatives:
  • Established organisations like CDP and the Science Based Targets Initiative offer voluntary frameworks.
  • The UN Expert Group defines gold standards for net zero targets of non-state entities.
  • The UN Recognition and Accountability Framework (RAF) aims to improve transparency and comparability.
  • The UN Climate Champions’ Race to Zero campaign mobilises thousands of non-state actors to commit to credible net zero.
