Responsible Expansion: Nuclear Energy, Data Centers and the Living World

Practical principles for expanding nuclear energy and data-center infrastructure while protecting ecosystems, communities and future generations.

Expanding nuclear energy and data-center infrastructure may help societies meet growing electricity demand, support scientific research and reduce dependence on high-emission energy sources. But technological progress does not remove humanity’s responsibility toward the Earth or the people and species who depend on it.

The question is not simply whether new reactors and data centers can be built. It is whether they can be planned, operated and eventually retired without treating ecosystems, communities and future generations as expendable.

Start With the Need, Not the Project

Every major project should begin with a clear assessment of its necessity. Governments and companies should publish expected energy demand, efficiency assumptions, alternatives considered and the public benefits the project is intended to deliver.

Data centers should not be approved merely because demand is projected to grow. Operators should first reduce unnecessary computation, improve software efficiency, extend hardware lifespans and use existing capacity more effectively.

Nuclear expansion should also be evaluated alongside efficiency, renewable energy, storage, grid improvements and demand-management measures. Building more infrastructure should not become an excuse to avoid reducing waste.

Protect Ecologically Valuable Places

Nuclear plants, data centers, transmission lines and supporting infrastructure should be kept away from critical habitats, wetlands, migration routes, old-growth forests, agricultural land and areas vulnerable to flooding, drought or wildfire.

Environmental assessments should examine cumulative impacts rather than evaluating each facility in isolation. Roads, cooling systems, construction activity, water use, waste storage and transmission infrastructure can collectively cause more ecological disruption than any single project suggests.

Where damage cannot be avoided, projects should demonstrate how it will be minimized and restored. Compensation schemes should not be used as permission to destroy irreplaceable ecosystems.

Treat Water as a Community and Ecological Resource

Cooling systems can place significant pressure on rivers, lakes, aquifers and municipal water supplies. Developers should disclose projected water consumption in normal, drought and emergency conditions.

Facilities should prioritize closed-loop, reclaimed or non-potable water systems where feasible. They should also avoid drawing water needed for drinking, agriculture, fisheries and wetlands, particularly in regions already experiencing water stress.

Nuclear facilities must maintain strict safeguards for cooling water, radioactive materials and thermal discharges. Heated wastewater should not damage aquatic habitats or alter local ecosystems.

Make Safety a Long-Term Obligation

Safety should be designed into every stage of a project, from site selection and construction to operation, decommissioning and waste management.

Nuclear operators should maintain independent oversight, transparent incident reporting, emergency planning and secure funding for eventual decommissioning. Safety systems should account for earthquakes, flooding, extreme heat, sea-level rise, wildfires, cyberattacks and other changing risks.

Data centers also require strong physical and digital safeguards. Their energy systems, backup generators, batteries, cooling equipment and chemical storage should be managed to prevent fires, contamination and harm to nearby communities.

No operator should be allowed to transfer long-term risks to the public after private revenues have been collected.

Build With Communities, Not Around Them

People living near proposed facilities should receive clear information before decisions are made. Consultation should begin early, continue throughout the project and include accessible technical explanations rather than promotional material alone.

Communities should have meaningful opportunities to challenge assumptions, request independent reviews and influence project conditions. Indigenous nations and local communities must have their rights, knowledge and governance structures respected.

Benefits should also be shared fairly through local employment, infrastructure investment, energy affordability and long-term community funds. A project should not be considered responsible if it provides electricity or computing capacity while exposing nearby residents to disproportionate risks.

Use Energy and Computing Efficiently

The cleanest unit of energy is often the one that does not need to be generated. Data-center operators should publish energy-use effectiveness, cooling performance, hardware utilization and the purpose of the computing workloads they host.

Companies should reduce redundant data storage, limit energy-intensive computation where it provides little social value and schedule flexible workloads when the grid has lower demand or greater availability of low-carbon electricity.

Nuclear power can support reliable electricity systems, but its use should be paired with efficiency improvements rather than unlimited growth in consumption.

Account for the Full Material Footprint

Responsible infrastructure planning must include the minerals, concrete, steel, electronics and fuel required to build and operate facilities.

Developers should assess mining impacts, manufacturing emissions, worker safety, transport requirements and supply-chain transparency. Data-center operators should reuse and repair equipment where possible, design for component replacement and ensure responsible recycling at the end of a product’s life.

Nuclear projects should also account for fuel sourcing, spent fuel, radioactive waste and the protection of workers and communities involved in the nuclear supply chain.

Require Transparency and Independent Measurement

Operators should publish regular data on energy use, emissions, water consumption, waste, ecological impacts, safety events and community commitments.

These figures should be independently audited and presented in formats that the public can understand. Claims about “clean,” “sustainable” or “carbon-free” operations should include the full life cycle of the facility rather than focusing only on its day-to-day electricity generation.

Independent regulators, universities, civil-society groups and local communities should be able to inspect relevant information without being blocked by overly broad confidentiality claims.

Plan for Closure Before Construction

Every project should have a funded and legally enforceable end-of-life plan before construction begins.

For nuclear facilities, this includes decommissioning, site remediation, spent-fuel management and long-term monitoring. For data centers, it includes equipment reuse, electronic-waste disposal, demolition, soil protection and restoration of water and habitat.

The financial responsibility for closure should remain with the operators and beneficiaries of the project—not with future taxpayers or communities that had no role in approving it.

Measure Success by More Than Output

A project should not be judged only by megawatts generated, computing capacity installed, construction speed or economic growth.

A more responsible set of questions is:

Responsibility	Practical question
Ecological protection	What habitats, species and natural systems could be affected?
Water stewardship	Will the project compete with people, farms or ecosystems for water?
Community well-being	Who receives the benefits, and who carries the risks?
Climate responsibility	What are the project’s full life-cycle emissions?
Resource use	Can the facility use less energy, land, water and material?
Safety	Who is independently monitoring risks and enforcing standards?
Future obligations	Who will pay for waste management, decommissioning and restoration?
Transparency	Can the public verify the project’s environmental claims?

Nuclear energy and data centers can form part of a lower-emission future, but neither should be treated as automatically sustainable. Their legitimacy depends on the care with which they are designed, governed and limited.

Human responsibility means recognizing that energy systems and digital infrastructure exist within a living world. Progress should therefore be measured not only by what societies can build, but by what they choose to protect while building it.
