Portfolio Management

Open Risk White Paper 17: Sustainable Public Procurement. Part I: Emissions Attribution

Public Procurement represents a major opportunity to catalyze the transition of economies towards more sustainable patterns but faces important challenges. We review mechanisms that can help address key pain points through the use of open standards, open data and open source tools. In the first part we frame the overall task of Sustainable Public Procurement as an instance of portfolio management. We outline three distinct information processing pillars that are relevant in this context. We focus here on the task of measuring and attributing greenhouse gas emissions to an existing procurement portfolio.

Summary

There are dozens upon dozes of indices that aim to measure concentration risk (and related concepts such as diversity or inequality). Why such a proliferation of alternatives? There are multiple reasons, which we will attempt to identify in this post. This enumeration prompts us to dig deeper into the nature of concentration indices and their various pros and cons.

Summary

We imagine the random propagation of money flows through simplified economic networks as a sequence of monetary transactions following a stochastic process. We follow the journey of a cash amount. Whenever a transaction in this chain implies an environmental impact, that impact is recorded and cumulated. Computing the expected outcome of such flows reproduces the standard results of environmentally extended input-output models. The random walk interpretation allows the computation of various additional statistical properties, one example being estimating a variance of environmental impact or intrinsic uncertainty around the central estimate. We interpret this uncertainty as being a concentration risk measure.

GHG Accounting offers a means of measuring the direct and indirect emissions to the Earth’s Biosphere of CO2 and its equivalent gases from industrial and other activities. GHG Accounting is a rapidly developing area that has come to receive increased focus in the context of accelerating Climate Change. Given that the generation of electricity and heat accounts for around a third of global GHG emissions electricity consumers have incentives to proactively reduce those emissions by reducing electricity demand, or by shifting energy supply by procuring alternative lower-carbon or renewable resources.

Course Objective

Digging into the meaning of credit data collections, the logic that binds them together towards understanding what they can be used for and what limitations and issues they may be affected by, this new course in the Credit Portfolio Management category explores a new angle to look at an old practice.

Modeling economic networks and their dynamics

Economic networks are the primary abstractions though which we can conceptualize the state (condition) and evolution of economic interactions. This simply reflects the fact that human economies are quite fundamentally systems of interacting actors (or nodes in a network) with transient or more permanent relations between them.

Introduction

In this fourth and final installment we will discuss how the data framework we have developed thus far can be mapped into classic portfolio management concepts and categories, and thus, how one can articulate the concept of sustainable procurement management on a portfolio basis. The concepts and analytic methodologies of financial portfolio management¹ can significantly enhance the toolkit available to practitioners and, in sense, connects the domain of Green Public Procurement to other ongoing initiatives in broader Sustainable Finance.

Introduction

This is the third in a series of posts where we explore the role of Open Data and Open Source in enabling and accelerating the broad based effort towards Green Public Procurement (GPP). In this third installment we will link procurement entities to private sector sellers and, through the sectoral profile of the procurement contract, (CPV category) we will infer the amount of CO2 emissions that can be attributed to these activities.

This is the second in a series of posts where we explore the role of Open Data and Open Source in enabling and accelerating the broad based effort towards Green Public Procurement (GPP).

Introduction

In a series of posts we will explore the role of Open Data and Open Source in enabling and accelerating the broad based effort towards Green Public Procurement (GPP). There are several important (and possibly obscure) terms in this sentence, so our first order of business will be to unpack them.

What is the EU Datathon?

The EU Datathon is an annual Open Data competition organised by the Publications Office of the European Union since 2017. The competitions are organised to create new value for citizens through innovation and promoting the use of open data, in particular the datasets available on the official portal for European data.

Equinox 0.4 Release

Equinox is an open source platform that supports holistic risk management and reporting in the context of Sustainable Portfolio Management. The platform integrates geospatial information with applicable regulatory and industry standards, for example the GHG Protocol (accounting for Project based, Corporate and City-Wide greenhouse gas emissions), the IPCC Emissions Factor database and further reference data, the PCAF attribution methodologies (and more) to provide a holistic view of the footprint of both individual projects and portfolios.

Course Objective

The objective of the course is to discuss the relation of economic input-output models with graph theory and networks.

Equinox is an open source platform that supports the holistic risk management and reporting of major sustainable finance projects (the financing of projects with material physical footprint) such as project finance.

Equinox aims to integrate in the database a number reference databases that facilitate tasks of sustainable portfolio management. In the current focus such reference material concerns the emissions factors for various processes and activities. In the latest (Solstice Day!) update of the Equinox Project we discuss the integration of reference data an in particular greenhouse gas emissions factors as catalogued in the IPCC Emissions Factors database (EFDB).

The frontpage graphic is adapted from Steffen et al. “Planetary Boundaries: Guiding human development on a changing planet”. Science (2015). The Planetary Boundaries concept was proposed in 2009 by this group of Earth system and environmental scientists. The group suggested that finding a “safe operating space for humanity” is a precondition for sustainable development. The framework is based on scientific evidence that human actions since the Industrial Revolution have become the main driver of global environmental change.

Open Risk White Paper 11: Sustainable Portfolio Management: Attribution and Allocation of Greenhouse Gas Emissions

We develop an analytic framework that synthesizes current approaches to sustainable portfolio management in the context of addressing climate change. We discuss the different required information layers, approaches to emissions accounting, attribution and forward-looking limit frameworks implementing carbon budget constraints.

Open Risk White Paper 10: Connecting the Dots: Concentration, diversity, inequality and sparsity in economic networks

In this second Open Risk White Paper on Connecting the Dots we examine measures of concentration, diversity, inequality and sparsity in the context of economic systems represented as network (graph) structures. We adopt a stylized description of economies as property graphs and illustrate how relevant concepts can be represented in this language. We explore in some detail data types representing economic network data and their statistical nature which is critical in their use in concentration analysis. We proceed to recast various known indexes drawn from distinct disciplines in a unified computational context.

Summary

The Open Risk Academy course NPL270672 is a CrashCourse introducing the EBA NPL Templates.

Content

We start with the motivation for the templates and the domain of credit data (to which NPL data belongs). We discuss three core classes that capture the essence of lending operations from a lenders point of view (Counterparty, Loan, Collateral). Next we explore classes that capture events in the lending relationship lifecycle (which we term NPL Scenarios). We look into the main data types: elementary data types, choice lists, arrays and unstructured text. We close with discussing some more complex issues involving graph and timeseries data.

Motivation

Equinox is an open source platform that supports holistic risk management and reporting of Sustainable Finance (Sustainable Portfolio Management). The platform integrates geospatial information with applicable regulatory and industry standards from EBA, PCAF and Equator Principles to provide a holistic view of the footprint of both individual projects and portfolios, in particular of project finance investments.

Celebrating Pi Day 2021

Pi Day is celebrated every year on March 14th. The reason of course is that the day is denoted in some calendars as (3/14), which evokes of 3.14, the first three digits of “π”. A thin excuse maybe but sufficient for the true believers to join along! The occasion represents an annual opportunity for mathematics and science enthusiasts to recite the infinite charms of Pi, including its irrationality, to talk to friends and family about math and its uses, and, when everything else fails, simply eat pie.
