Create solutions to three distinct climate challenges using CDP’s Corporate and Cities Data

CDP is a global environmental impact non-profit working to secure a thriving economy that works for people and the planet.

We focus investors, companies and cities on taking urgent action to build a truly sustainable economy by measuring and understanding their environmental impact. 

IMPORTANT: You must complete the hackathon registration and data release here to participate

CDP’s unique data is used globally by capital markets, corporations, policymakers, and other institutions to inform purchasing decisions, investment portfolio selections and environmental performance benchmarks. However, in many applications, CDP’s data remains underutilized due to the growing volume and complexity of data available. 

This hackathon is intended to allow expert users to get hands-on with CDP data, identify opportunities within the data and across other datasets, derive insights and build new tools and visualizations to unlock new potential from this information.

Additionally, we hope this competition helps raise awareness of climate change, water security, deforestation risk and city resilience, and the role corporate and city data can play in finding solutions. We hope to identify areas of impact that CDP data can have on climate change mitigation strategies and solving real-world climate challenges.  

The overall goal is to identify opportunities for collaboration between various stakeholders. Since each stakeholder accesses, calculates and submits their CDP response independently, the data can remain siloed. By applying data analysis tools, we hope to identify and unlock opportunities for collaboration, comparison and learnings across companies, cities, states, regions, investors and other interested parties.

Secondary goals of the data competition include validating/verifying data being reported, predictive models for future scenarios, strengthening of guidance for how to report data, identification of additional datapoints to gather and request, etc. 

Participants will choose one of the three challenges outlined below. More detail on the challenges will be released prior to the hackathon start date.

Challenge 1: City-Business Collaboration

Over 8,000 companies and almost 1,000 cities, states and regions disclose valuable sustainability data through CDP each year, however each prepares and submits their report independently. Many companies and cities are reporting data identifying very similar risks and opportunities, however they are not able to connect to address them together effectively. Public-private partnerships can enable collaboration on things like clean energy, sustainable buildings, clean transport, waste and circular economy that are too big for one entity to tackle alone. For example, CDP has been a partner in the City Business Climate Alliance, which identifies actions businesses within a city can take to help the city achieve its climate plan.

In order to connect companies and cities together, we need to first understand how the data they each report is aligned or divergent by using data science and text analytics techniques. Then, we can begin to identify where there might be opportunities for collaboration and co-investment for mutual sustainability goals that will ultimately benefit all citizens of the city.

Challenge 2: Water Security/Climate Risk

Water security is one of the most basic human rights, yet there are a surprising number of examples of U.S. cities – from Flint to Newark to Dos Palos, CA – where it is not a guarantee. Water security issues today can be considered a leading-edge indicator of deeper climate risks in the near future – droughts, floods, hurricanes, coastal flooding – which will strengthen in intensity and frequency.

CDP collects great quantities of information from cities and companies on water security and expected climate risks, and a lot of that information is in the form of free form text. This makes it hard to analyze and compare, as companies and cities might report the same risks but with different magnitudes, likelihoods or potential impacts. Furthermore, CDP’s recent report highlights that future and long-term risk is critically underreported. In fact, the biggest risk is when a key stakeholder does not acknowledge a risk at all!

In order to help companies and cities fully understand their current water security and future climate risks we must first inspect this free text data in comparison with their peers, suppliers and neighbors. Cities will benefit from an analysis of reported long-term risk with projected climate risk from specific water-stressed river basins. With a more complete understanding of the full scope and magnitude of potential impact, we can begin to identify who is uniquely positioned to address each aspect of concern.

Challenge 3: Renewable Energy Demand Projects

Renewable energy is the fastest-growing energy source in the United States, doubling from 2000 to 2018. Much of this growth is driven by shifting demand signals from cities and companies who are committing to source 100% renewable energy such as through RE100. However, most of the new solar, wind, biomass, ocean power, etc. has been going to fulfill new electricity demands, not replacing old, dirtier baseload power. And far too few metropolitan areas or electric utilities are leading the effort, nor are there enough supportive state-level policies (such Renewable Portfolio Standards) guiding the path forward.

Currently only just over 10% of U.S. electricity comes from new renewable sources and this needs to ramp up quickly. In Canada, large-scale hydro power contributes base load but is not the most sustainable option in the future. CDP’s company and city data provides a window into the demand side of renewable energy, both today and in the future. By focusing on matching renewable energy supply to meet demand signals in a given metropolitan area or electric utility’s service area, we can help green the electric grid more quickly.
