Sandbag is very happy to announce the beta release of our EU Emissions Trading System Dashboard, a tool that provides a user-friendly and interactive access to emission trading data extracted from the European Union Transaction Log (EUTL) together with other data integrated by Sandbag’s team (e.g. auction data and a more meaningful sectors aggregation).

Cement sector emissions in Italy, Germany and Romania. Nearby installations emissions are aggregated, hover over the circles and you will see the specific area they represent.


I am excited to present a 100% open-source tool using interactive visualizations to give an insight into Europe’s greenhouse gas emissions.

Many different options can be found for the visualization of data on the web, but very few are interactive. Climate Change visualizations seem to be way behind compared to other fields such as bioinformatics, despite the complexity of emissions data.

Thus our approach for the implementation of this web application overcomes limitations of single visualizations by supporting exploration of the data through interaction. This gives the user the possibility to not only visualize subsets of the data, but also find stories hidden in it by applying different types of filters in real-time. And we want your help finding these stories!

Through careful study of the data, analysts at Sandbag have previously helped to expose and ban gluts of dodgy offsets from HFC projects; discovered that the European Commission’s emissions model is based on outdated assumptions; and shown that the Market Stability Reserve wouldn’t have the impact industry said it would.

Can you spot anything in this new data visualisation which will guide Sandbag’s next campaign? Perhaps you would like to see the data presented in a different way or a new function? Email with your ideas.

How the Dashboard works

The EU ETS Dashboard consists of four different views where the user can inspect the data from the following perspectives:

  • EU Wide

  • Country + Sector

  • Installation level map

  • Data per period

Each of them includes a different type of visualization in order to best represent the data at the corresponding level of granularity.

This tool is also an effort to bring innovative cutting edge technologies to a field that unfortunately is lagging behind in this sense.

For the back-end we are using Neo4j Graph Database – A highly scalable native graph database, and Amazon Web Services for the deployment of the tool.

The front-end uses the following libraries and technologies among others:

  • D3.js – Data-driven documents

  • Dimple.js – An object-oriented API for business analytics powered by D3

  • Bootstrap – The most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web

  • jQuery – a fast, small and feature-rich JavaScript library

  • Leaflet – an open-source JavaScript library for mobile-friendly interactive maps

It’s a work in progress, so we’re interested to hear your suggestions. Contact if you’d like to see another feature.

The Emissions Trading System is a market in carbon dioxide allowances. All power stations and large industry in the EU are legally required to surrender an allowance for each tonne of greenhouse gas they release into our atmosphere. The ETS sets a gradually declining cap on the number of these allowances, and thus a price on CO2, with the intention of driving down emissions. Unfortunately, poor system design and the effects of the 2008 financial crisis means the carbon market isn’t working: one allowances representing a tonne of CO2 is only worth ~€4.50 today, far too low to drive change. Sandbag is working to fix this market and rapidly bring down emissions.
