What We Do

Neyen builds data analytics systems to drive transparency, comparability and trust. We have extensive expertise in designing assessment methodologies and benchmarks to analyze climate and sustainability performance and developing ratings for international finance institutions and other entities with an interest in analyzing how the world advances towards reaching the goals of the Paris Agreement. Assessment methodologies are designed to benchmark performance using environmental, social and governance (ESG) standards.

Public sector

We perform assessments of carbon pricing instruments performance at all levels: from climate action at the municipal and regional level, adaptation at the community level, and country level readiness to act under international cooperation.

Our assessment protocols to assess city- and state-level Climate Action Plans have been applied across Europe, Asia and Latin America. We also design other sustainable development rating protocols for mitigation actions, sustainable development impact and Community-based Resilience Evaluations.

We assess country readiness to participate in international mechanisms such as Article 6 units and international carbon market structuring and evaluation. Previous projects include assessing MRV systems in the countries of the Pacific Alliance and piloting World Bank MAAP ITR (International Transfer Readiness) in multiple countries.

Financial Institutions

The diversity of GHG programs and carbon units in the market make it challenging for offset buyers to select units have the level of integrity and contribution to sustainable development aligned with their corporate values. We take into account specific ESG risk categories in assessing these assets ex-ante and ex-post. 

Through the use of data analytics, we provide ESG assessments of carbon assets along with evaluating the alignment of financial institution investments towards a 1.5°C goal.

Our methodology can be applied to voluntary market offsets along with carbon offsets from regulated mechanisms (including the Clean Development Mechanism and future Article 6.2 and 6.4 mechanisms).


We design corporate sustainability rating protocols (corporate sustainability indexes, social, environmental and economic impact of corporate practices), taking ESG standards into account. This includes Corporate Certification (first and second party, international standards).

Additionally, this can be applied to other corporate needs such as project benchmarking, adaptation performance for specific sectors utilities, and Net Zero pledges benchmarking.

Using data, benchmarking, and other tools, this process can ensure that corporations meet their Net Zero goals and that claimed emissions reductions are real.
