Comparing City Carbon Emission Tools: SCATTER and Google EIE

October 14, 2019 | Insights

What is SCATTER?

A city-focused emissions tool to measure carbon outputs, set reduction targets and implement a plan of action.

From A Coruña in Spain to Bulawayo in Zimbabwe, 9155 cities across the globe, representing more than 770 million residents, have committed to reducing their carbon footprint to meet the goals of the Paris Agreement.

Some of the world’s biggest cities, including Rio de Janeiro and New York, have pledged to reduce their carbon output by 80 percent within the next 30 years.

One big question looms – how are they going to achieve this?

Only a small proportion of cities have completed and submitted an inventory of emissions, let alone monitored their footprint levels to check progress. Gathering carbon outputs for a whole city requires a huge amount of data from multiple sources – how is it possible to gather this much information to give an accurate emissions total?

Carbon footprint tool for cities – Google enters the market

The Environmental Insights Explorer (EIE) from Google puts the Anthesis-developed SCATTER tool in the spotlight.

The Google Environmental Insights Explorer tool, created in partnership with the Global Covenant of Mayors for Climate & Energy, has been designed to give cities and local governments access to their current emission levels, so they can build a plan to reduce and measure emission levels.

Using data from Google Maps alongside standard greenhouse gas (GHG) emission factors, EIE estimates three city-level data points: building emissions, transport emissions and renewable energy potential (solar).

SCATTER integrates five key technologies to deliver on carbon reduction: carbon capture, decarbonising heat, energy efficiency, electrifying transport and recycling infrastructure improvements and bio-energy.

How will the EIE Tool be used?

The tool highlights the significant scale of city emissions and with it their role in being part of the solution. Using common methodology that can be standardised and scaled, it makes it easy for cities to benchmark their emissions against other cities. The tool will be used by city policymakers to develop clear plans of action to reduce their carbon emissions.

Comparing EIE and SCATTER

In 2018, we expanded our sustainability software portfolio with the launch of our carbon footprint reduction tool – SCATTER. It builds upon similar details provided by the EIE to allow cities to drill into the interventions; the areas of activity where the potential for carbon reduction lies.

Whereas Google looks at three main interventions – buildings, transportation and solar – SCATTER incorporates a comprehensive list of 45 interventions.

Whereas Google looks at three main interventions (buildings, transportation and solar), SCATTER focuses on a comprehensive list of 45 interventions. Google helps to identify the scale of the problem, while SCATTER enables cities and regions to develop a picture of the solution by building up future reduction scenarios from detailed practical from detailed practical areas under a city’s control.

This supports local climate action planning and responses to the climate emergency, as well as allowing cities and governments to get an accurate handle of their current emissions and set carbon reduction trajectories and targets that are driven by a technology-led approach. This leads to evidence-based targeting setting and informed policy making.

What’s Happened with SCATTER Since the 2018 Launch?

Since the launch of SCATTER at the Greater Manchester Green Summit, it has been used by Greater Manchester, Oxford, Bath and North East Somerset and Birmingham to provide an evidence base for their carbon reduction plans. BEIS also funded Nottingham City Council to take forward enhancements to SCATTER, making it a free web-based tool assisting local authorities on:

  • The ability to report on authority wide emissions to carbon reporting frameworks and inform the setting of carbon reduction targets
  • The ability to understand potential carbon reduction pathways and interventions to reach carbon commitments, in-line with national and international objectives.
  • Visual outputs to engage stakeholders in the development of carbon reduction plans.

The SCATTER tool was also upgraded in autumn 2019 to allow local authority users in the UK to map out emissions reduction pathways for their area to 2050. Pathways allow SCATTER users to select the level of ambition for a range of interventions and model different scenarios for their emissions reduction pathway to 2050.

Aside from the UK, we are also talking to stakeholders in Europe to see how SCATTER can translate to Scandinavia.

Further Uses of SCATTER – CDP Submission and the Commercial World

Multiple users have also used SCATTER to obtain the data for carbon disclosure, such as CDP, where companies, cities and regions submit data on their environmental performance. As of September 2018, over 500 cities disclosed their environmental information through CDP 2018.

Within each city-region, we’re also working with sector leads using the SCATTER tool as an effective and dynamic stakeholder engagement vehicle. We’ve spoken to leaders in commercial organisations, housing associations and domestic, transport, energy distributors, technology providers and academic institutions.

Data Visualisation – Simple Interpretation of Complex Data

Not only is SCATTER supporting CDP submissions, it also has a range of standard outputs that can translated using the latest data visualisation software to support messaging and make it simple for policymakers and planners to explore future carbon reduction scenarios. Robust datasets are only as good as the user’s ability to interpret it, so ‘Seeing’ the outcome of the policy decisions they may or may not decide to make is a crucial to simplifying complex data.

For example, a city could model the impact of improving energy efficiency in buildings via retrofit scenarios and new technologies to reduce heat leakage. Or a city could track how carbon capture storage will reduce emissions from industrial use and power generation before investing. Being able to see the potential impacts is a huge benefit for decision makers.
