Climate Action Enhancement Package (CAEP): Lessons in Developing Implementation Ready NDCs


The NDC Partnership’s demand driven model enables countries to flag their specific needs and receive targeted support to enhance and implement their Nationally Determined Contributions (NDCs).

Transformational change is needed to cut emissions and adapt to a changing climate, all while meeting development needs. Such change requires groundbreaking coordination to mobilize resources globally, with speed and scale.

CAEP was launched in 2019 to provide countries with rapid and dedicated support to enhance the quality, process and ambition of their NDCs in 2020.

The NDC Partnership’s Climate Action Enhancement Package (CAEP) was launched in 2019 to help countries enhance their Nationally Determined Contributions (NDCs) and fast-track their implementation.

Through CAEP, countries received a diverse range of support for their NDC enhancement.
Partnership Model at Work

The NDC Partnership deployed over $51 million in support of NDC update efforts of 67 developing countries. This was delivered through the technical and financial contributions of 46 implementing partners, illustrating the impact of the Partnership model.

Assessment of Enhanced NDCs

An assessment of 55 NDCs was carried out, which identified various characteristics of the support provided and it's impact on ambition, quality, and process.

CAEP Support Linkages

Updates to NDCs were mapped against the CAEP support received by each country, highlighting where the specific objectives of CAEP activities were realized.

Quality and process are the critical enabling components for ramping up ambition. NDC enhancement is measured across all three components.


Targets are credible, comprehensive, robust and implementable


Emissions reductions are in alignment with Paris goals; spanning relevant sectors and gasses, and aligning with long term plans


The NDC process is inclusive and transparent, building up national ownership

global insights

NDC enhancement is multifaceted, including ambition, quality and process.

  • Enhancement is identified by comparing a country’s first or second NDC with its updated one.
  • By comparing an NDC against its previous version, the analytical focus is relative rather than an absolute assessments of NDCs.
  • This comparison illustrates the principle that NDCs are designed to serve specific country contexts and priorities and should be considered relative to their own previous iterations.


Ambition refers to strengthening mitigation or adaptation targets and actions over time.

Countries may raise ambition by strengthening emissions reduction (including the addition of sector-specific targets) or by broadening the scope to include wider coverage of sectors or gases. Countries may also raise ambition by moving from conditional to unconditional targets, shortening timelines, adding qualitative policies and measures, or setting out their long-term adaptation strategies.

Out of the 55 countries assessed, 55 countries raised their NDC ambition, 54 of which received CAEP support to do so.

Quality enhancement includes strengthening underlying data and ensuring NDCs are detailed, achievable and verifiable.

Data gathering and robust methodologies support evidence-based NDC targets and detailed action plans, including sector-specific plans, costing, and financing. Clear governance structures and strategic alignment with national policy and Long Term Strategies (LTS), including additional information on capacity gaps and barriers to inform adaptation planning, and ensure the targets are achievable given countries’ resources. Including or strengthening mechanisms for monitoring and oversight is important for tracking progress and verifying the set targets.

CAEP supported all 55 countries with analytical and technical support, improving overall NDC quality.

Process captures enhancement in NDC transparency and inclusiveness of key stakeholders and vulnerable communities.

These components strengthen the credibility of NDCs, ensuring inputs and targets reflect the needs and priorities of impacted communities. It includes designing strategies to mainstream climate change through education and awareness-raising campaigns. An inclusive process leads to greater involvement of all levels of government as well as the public, following a whole-of-society approach.

CAEP supported all 55 countries in enhancing their NDC process with support targeting inclusiveness, transparency and stakeholder engagement.
