Using the Kraljic Matrix in Green Public Procurement

Using the Kraljic Matrix in Green Public Procurement

In this post we discuss on the possible uses of Kraljic Matrix concepts in the context of Green Public Procurement

Reading Time: 15 min.

Motivation

Sustainable Public Procurement involves significant complexity and implementation barriers as it involves diverse categories of products and services, each with their own specific sustainability and knowledge requirements. It also requires augmented organizational capacities to handle expanded information flows that provide more holistic views on market capabilities and supply chain inter-dependencies.

On the ex-ante evaluation of Green Public Procurement criteria

On the ex-ante evaluation of Green Public Procurement criteria

In this post we outline a scheme for the consistent, portfolio-wide quantification the effect of Green Public Procurement criteria on environmental impacts of procurement activities.

Reading Time: 11 min.

Motivation

GPP is defined as a process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life-cycle when compared to goods, services and works with the same primary function that would otherwise be procured. Unpacking that definition helps pin down many important characteristics of the information gathering and processing that must take place to support this major sustainability transition process. A most striking high-level aspect is the vast scope of this process: With public procurement forming anywhere from 10% to 30% of an economy, there is vast variability in underlying economic activities, environmental impacts, market characteristics and procurement procedures. Nevertheless, the definition of GPP demands a certain degree of coherency across this vast domain, not least to ensure the cost and energy of public resources dedicated to GPP are effective in achieving their target.

The role of EEIO frameworks in Green Public Procurement monitoring

The role of EEIO frameworks in Green Public Procurement monitoring

In this post we provide a summary of the methodological approach and the opportunities and challenges when using Environmentally Extended Input-Output databases and models to assist with the implementation of Green Public Procurement Monitoring Processes.

Reading Time: 17 min.

Motivation

The public sector avails of significant purchasing power when contracting with the private sector for goods, works and services. This provides it with meaningful leverage across a good fraction of economic activity. Significant efforts are underway worldwide to utilize this leverage towards achieving sustainability goals. Yet implementing sustainable procurement at scale remains a task of enormous complexity that requires significant investment in different areas: in developing suitable policies, in establishing appropriate information flows and methodologies and, not least, in embedding these new practices and behaviors across swathes of economic activity.

In this blog post we provide a brief overview of how an important class of economic analysis tools termed EEIO, or environmentally extended input-output frameworks, can be utilized to support the implementation of key public procurement sustainability objectives. We sketch the nature of these tools, how they can be used to provide relevant information, and the pros and cons of such an approach.

Taking Stock of the United Nations Open Source Principles

Taking Stock of the United Nations Open Source Principles

In this post we endorse the UN Open Source principles and take stock on their implications for the domains of risk management and sustainable finance. We also take a step back and discuss how open source is an essential ingredient for the PODA manifesto, namely putting people above data and algorithms.

Reading Time: 7 min.

What are the UN Open Source Principles?

The UN Open Source Principles is a set of eight high-level guiding principles that were recently adopted by the UN Chief Executive Board’s Digital Technology Network (DTN). They open a new window and provide guidelines to drive collaboration and Open Source adoption within the UN and globally. They send a strong signal of the importance of open source and how individuals and organisations need to act to benefit but also support a thriving and sustainable open source community.

Why are there so many concentration indices?

Why are there so many concentration indices?

We discuss the proliferation of indices and metrics for computing concentration risk (and related diversification and inequality indices). We go over underlying reasons for such proliferation.

Reading Time: 7 min.

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.

What Can We Learn From Random Walks on Input-Output Tables

What Can We Learn From Random Walks on Input-Output Tables

In this post we elaborate on the insights we can derive when using well established Environmentally-Extended Input-Output frameworks in a slightly different manner, as the canvas for monetary random walks "following the money"

Reading Time: 20 min.

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.

Representing Matrices as JSON Objects: Part 2 - Sparse Matrices

Representing Matrices as JSON Objects: Part 2 - Sparse Matrices

Representing a Sparse Matrix as a JSON object is a task that appears in many modern data science contexts. While there is no universally agreed way to achieve this task, in this post we discuss a number of options and the associated tradeoffs.

Reading Time: 11 min.

Recap of Part 1 of the Matrix-to-JSON Post Series

In the first installment of this series, Part 1 we discussed the motivation behind representing and serializing matrices as JSON objects. We defined relevant concepts and in particular the concept of unrolling the matrix into a one-dimensional array and the notion of Column and Row Major orders. We outlined some use cases of interest and initiated a benchmarking exercise that looks into various R and Python JSON serialization utilities (available at the matrix2json repository).

Towards a Faceted Taxonomy of Financial Services

Towards a Faceted Taxonomy of Financial Services

In this post we are after a flexible financial services taxonomy that can help us understand both existing and evolving financial system developments. To this end we examine a range of existing classification systems and synthesize the salient requirements.

Equinox 0.7 release focuses on scope 2 (electricity) emissions

Equinox 0.7 release focuses on scope 2 (electricity) emissions

New data models introduced in this release of Equinox cater to the requirement of integrating energy attribute certificate information into the portfolio database.

Reading Time: 3 min.

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.

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.

White Paper: Deep Linking Financial and Energy Accounting

White Paper: Deep Linking Financial and Energy Accounting

We develop a conceptual framework for integrated accounting that imposes on certain non-financial disclosures the same double-entry balance constraints that apply to conventional financial statements. We identify the key ingredients required for a rigorous multidimensional accounting framework in terms of concepts, postulates and design choices, and we illustrate these ideas with a worked-out example of linking financial and energy accounts.

Reading Time: 9 min.

Integrated Energy Accounting is keeping track and reporting on an entity’s detailed energy footprint (primary inputs, transformations and waste generation) not as an addendum to financial accounting and reporting but as a deeply-linked extension that is subject to the same level of rigor.
