Carbone 4 launches Carbon Impact Analytics

1 October 2015

An innovative methodology which measures the carbon impact of an investment portfolio.

For an investor or an asset manager, measuring the impact of financial investments on climate change is a vital stage of portfolio construction which contributes to the transition towards a low- carbon economy.

Carbon Impact Analytics is an innovative methodology which measures the carbon impact of an investment portfolio, by:

• Measuring greenhouse gas emissions produced or avoided by the companies held in a portfolio, throughout their entire value chain (scope 1, 2 and 3). Carbon Impact Analytics also measures emissions produced or avoided by products and services sold;

• Assessing a portfolio’s contribution to energy and climate transition.

Carbon Impact Analytics thus measures greenhouse gas emissions associated with investment assets and their contribution to emission-reduction, which is now a regulatory requirement under article 173 of the Energy Transition for Green Growth law. It is also a decision-making tool which can be used to rotate investments towards companies which are contributing to energy and climate transition, via their “green” business activities.

Asset managers are provided with a detailed analysis of the carbon impact of the companies held in their portfolio and the results can be consolidated across the entire portfolio. The methodology used in the initial version, covers global equities and bonds issued by listed companies. The analysis, which is carried out on a company-by-company basis, aims to encourage dialogue with the companies over time.

Carbon Impact Analytics has been developed in partnership with Mirova, the responsible investment subsidiary of Natixis Asset Management and with the support of MAIF.

Carbon Impact Analytics methodology

“Bottom-up” analysis

The carbon impact analysis of a portfolio begins with a detailed assessment of each individual investment. An aggregate weighting of the results is then established for the entire portfolio. The Carbon Impact Analytics evaluation thus differentiates between companies within the same business sector and assesses the efforts they have undertaken to integrate climate issues into their strategies, in order to implement a stock-picking approach based on carbon impact criteria.

Sectorial approach with specific insights for “high stakes” sectors

The challenges for low-carbon transition vary according to economic sector, both in terms of leverage to reduce emissions and also in terms of innovation. For this reason, Carbon Impact Analytics proposes a specific approach for the most challenging sectors, using a different methodology adapted to each sector.


The quantitative emission assessment (produced or avoided) is complemented by a qualitative trend score. On the basis of these elements, a global score is attributed to each company, providing an evaluation of its contribution to climate transition.

A detailed presentation of the Carbon Impact Analytics results feeding through to reporting and investment strategy

The results of the Carbon Impact Analytics evaluation are consolidated across the entire portfolio and provided for each company. The results include a range of quantitative and qualitative indicators, as well as statistical data for the entire portfolio.
