How can the vantage of space give you strategic advantage on Earth?

With Earth observation data now free and open to use, interested individuals and more crucially, commercial companies began to mine it, package it, and sell solutions.

"Business leaders still need education on what Earth observation data can do for them. They are asking, what is being measured, and how do I infuse it into my business? We are just beginning to unlock the huge potential of this treasure trove of insight," says Dr. Brian Killough, former NASA Earth Science leader.

Speeding disaster detection and response

Perhaps the most public use case for satellites is providing first responders situational awareness to efficiently allocate resources to those most in need. Machine learning applied to satellite data helped track the Australian bushfires in 2020. Similarly, satellite imagery aided the rescue and recovery efforts after New Zealand was hit by cyclone Gabrielle earlier this year.

‘We are going to revolutionise disaster response by leapfrogging communications and data technology. Edge computing on satellites and dedicated grounds stations will remove steps in putting critical imagery of ground conditions in the hands of first responders, reducing the turnaround time from a day or more to hours,’ says Dr. Rebecca Allan, Co-Director Swinburne Space Technology and Industry Institute.

Monitoring asset and infrastructure risk

Another important use case for remote sensing and observation is assessing key assets and infrastructure for exposure to natural hazards and risk of operational disruption. This capability particularly benefits businesses in sectors with critical, always-on infrastructure, such as energy, water, and transportation.

Satellite imagery helps asset-heavy enterprises:

• Plan for contingencies and redundancies.
• Monitor physical infrastructure not only for problems, but also signal for preventative maintenance.
• Avoid expensive ‘truck rolls’.
• Minimising human interactions with hazardous infrastructure.

Improving supply chain resilience

The need to build diverse and more resilient supply chains has become urgent in the wake of disruptions stemming from the COVID-19 pandemic. Satellite data helps to optimise routes and monitor production levels by assessing activity levels at factories, ports, and other supply chain links. Given the imaging resolution now possible, commodity traders can even assess the volume of oil production and trade from the shadow cast by oil tankers as they cross the oceans.

Combined with demand forecasts and other data, satellite data can support improved supply chain efficiency and inventory planning.

New skill sets and capabilities required

Numerous use cases demonstrate the opportunity to drive value with Earth observation and sensing data. However, realising this value requires specialised skills and capabilities which most companies don’t currently possess.

While custom high resolution images can be procured within hours, teams need to be able to bring together AI, machine learning and data science to distil insight from them.

For business leaders, the question of whether to build in-house capabilities or work with business partners will depend on several factors:

• Anticipated breadth of use of Earth observation and sensing data.
• Degree to which the data and capabilities will be strategic to the business.
• Opportunity for spill-over benefits into the organisation’s innovation and technology strategy.

Satellites provide this big picture and close-up perspective, generating increasingly rich data on the current state of the environment and how it’s changing.

As companies contend with new sustainability reporting expectations and requirements, the democratisation of space data creates new opportunities and new accountability:

• Growing volumes of rich space data offer companies a critical resource for assessing, reporting on, and improving their sustainability performance.
• An expanding ecosystem of public and private organisations utilising this data creates new opportunities for productive partnerships to accelerate corporate action on sustainability.
• Space data empowers stakeholders to monitor the sustainability performance of companies and hold them accountable to their pledges, increasingly limiting the ability of companies to selectively disclose and reducing their control over their sustainability narratives.

"Now is the time for private and public sector leaders to understand what Earth observation data reveals about their global footprint and impact, both to manage sustainability risks and accelerate progress on climate, biodiversity and other goals," says Amy Brachio, EY Global Vice Chair of Sustainability.

Eying global greenhouse gas transparency

Climate-focused non-governmental organisations (NGOs) are leveraging open-source satellite data and artificial intelligence to quantify and inventory the largest individual sources of GHG emissions.

Climate TRACE, a non-profit coalition, has mapped over 80,000 emitting physical assets globally in two dozen sectors, in addition to providing independent emissions estimates for every country on the planet.ⁱ The organisation synthesises data from 300 satellites and more than 11,000 sensors with other ground truth data sets to train AI/ML algorithms, which can then be used to make estimates globally.

"The public availability of satellite data has been tremendously helpful to us, along with advances in artificial intelligence and machine learning. We’re building on tried and tested analytical approaches and massively expanding them globally," says Lekha Sridhar, Senior Policy Analyst with WattTime, one of the Climate TRACE coalition member organisations.

Other NGOs are launching their own, purpose-built, satellite missions to identify and quantify emissions sources. The Environmental Defense Fund (EDF) and Carbon Mapper both will have satellites focused on detecting methane, a greenhouse gas 80 times more warming than CO2.

‘Satellite emissions monitoring also provides an important opportunity to build confidence in underground carbon capture and storage. Monitoring and verifying the lack of emissions from CCS sites could help answer concerns about leaks and accelerate the adoption of these solutions,’ says Mathew Nelson, EY Oceania’s Chief Sustainability Officer.

Together, organisations such as Climate TRACE, EDF and Carbon mapper will illuminate the climate performance of high-emitting industries at a very granular level while offering a hand of collaboration to companies seeking to improve.

Unlocking capital for nature-based carbon solutions

Concerns related to the monitoring, reporting and verification of nature-based carbon offsets and removals have constrained investment in both established classes of projects (e.g., forest preservation) and emerging ones (e.g., soil sequestration).

Increasing confidence in the additionality, performance and permanence of nature-based projects would help unlock the capital needed to scale carbon markets.

Satellites are already playing a role as organisations:

• Combine satellite remote sensing data with AI to define, quantify and certify carbon projects.
• Use satellite data to independently assess and rate nature-based projects, often highlighting disparities with reported performance.

Given the growing number of satellite data sources, coordination among standard-setting organisations on the use of satellite data and a system of assurance on satellite imagery would also bolster confidence in nature-based credits.

LEAPing into TNFD reporting with satellite data

Satellite data will likely become an important tool for many companies assessing and disclosing their nature-based risks under the Taskforce on Nature-based Financial Disclosures (TNFD).

Nearing its final release in September 2023, the TNFD’s four-step ‘LEAP’ assessment framework asks companies to report on nature-related dependencies, impacts, risks, and opportunities with a comprehensiveness many organisations will find both novel and challenging.

Satellites’ ability to provide both systemic and pinpoint insights into ecosystems anywhere can help many corporates to meet this assessment challenge, particularly in the ‘L’ step (Locate interfaces with nature) and the ‘E’ step (Evaluate dependencies and impacts).

While financial institutions typically do not possess the geo-location data of the physical assets and operations of their portfolio companies, satellite data can support TNFD assessment of more discrete investments (e.g., project finance, real assets, infrastructure).

Meeting the challenges of nonfinancial reporting

The ability of satellite data to provide insights into a wide range of sustainability issues can support voluntary and required nonfinancial reporting. Earth sensing and observation data can be applied to:

• Establishing ecological baselines and impacts relative to a company’s operational footprint.
• Determining local ecological thresholds and biodiversity characteristics.
• Providing insights into the sustainability performance of value chain participants.
• Substantiating sustainability claims and progress.

Integration of double materiality principles into national and international reporting frameworks, such as the EU Corporate Sustainability Reporting Directive, will likely accelerate the use of satellite data in nonfinancial reporting. As companies undertake impact assessments to establish double materiality, satellite data can provide important data related natural systems and resources.

‘The ability of satellites to provide multi-dimensional insights into natural systems over time – climate, pollution, water, biodiversity, and more – allows companies to better understand the context in which they operate and how their operations impact, and benefit from, biospheres. This could make satellite data an important contributor to companies’ baselining, target setting and monitoring of progress on sustainability,’ says Ben Taylor, EY Global Climate Change and Sustainability Strategy and Markets Leader.

Existential risks

The concern of collision risk is growing as operators put new constellations of satellites into orbit without deorbiting many defunct or failed pieces of hardware. Tiny pieces of debris can be lethal in the space environment. The task of keeping track of and manoeuvring around them increases in complexity daily.

A runaway cascade of collisions that knocks out global communications and navigation – the so-called Kessler Syndrome – presents the worst scenario.

A careful analysis of the system complexity of the Earth’s orbit is warranted. From the COVID-19 pandemic to the Ukraine war, our recent global experience underscores that low-probability, high-impact events occur. With growing geopolitical tensions, even a collision short of a Kessler event could lead us into uncharted territory.

Commercial complications

The increasingly complicated operating environment is the most immediate concern for commercial space operators. No central 'space traffic control' coordinates mission activity as the growing number of objects in space reduces time and room for manoeuvre.

Today, the owner of a satellite on a trajectory to impact another object must directly contact the other parties at risk to work out a plan to avoid collision. This diverts satellite resources from fulfilling customer orders, resulting in delay or loss of revenues.

New launches are becoming more difficult as time windows narrow due to the growing density of objects in orbit. “We’ve seen launch windows going from three hours to as little as three minutes in some cases,” says Peter Beck, CEO of Rocket Lab, who is pessimistic that any central coordination will be put in place without a serious collision event.

Privacy risks

The increasing resolution, ubiquity, and open-source availability of satellite imaging creates a growing ability to observe individuals, especially when combined with other forms of data and AI (e.g., mobile data, city/residential video, facial recognition).

Before we encounter unintended privacy consequences, governments, civil society, and the private sector must confront important questions, including:

• How do privacy regulations apply to space observation data?
• What is the right trade-off between the beneficial uses space observation data and individual privacy?
• How can regulators keep up with the pace of technology development and new applications?

‘The ethics and governance of Earth observation have not been discussed much, despite the growing capabilities and volumes of data collected by private entities. Managing these risks will be hugely important because misuse of observation data-intended or not-could cause operators to lose their social licence to operate,’ says EY’s Nelson.

New challenges, new players and new governance

How do we prevent a tragedy of the commons in Earth orbit? Engaging in long-term thinking about the sustainability and governance of orbital space is essential.

‘We must understand the systemic dynamics of space, the likely growth in space debris, and how these factors could affect the future use of space – in other words, the inheritance our generation will leave in space for future ones,’ says Hugh Lewis, Professor of Aeronautics and Co-director of the Centre of Excellence in In-situ and Remote Intelligent Sensing at Southampton University.
