Here’s something that keeps me up at night: the tech industry accounts for 2-7% of global greenhouse gas emissions, and this percentage is rapidly increasing as digitalization takes over.[^1] Even more troubling? Only 6% of organizations have a highly mature, sustainable IT strategy with clear goals and timelines.[^1]

I’ve spent years working with teams who genuinely care about sustainability. They attend the workshops. They nod at the presentations. They bookmark the articles. And then… nothing changes.

The problem isn’t that people don’t care. The problem is they don’t know where to start—or more accurately, they don’t understand the journey they need to take. That’s why the Sustainable IT Manifesto Foundation developed a framework that breaks down the overwhelming challenge of sustainability into four manageable, sequential steps: Aware, Conscious, Enabled, and Empowered.

In this post, I’ll show you how these four steps create lasting transformation, why most organizations plateau before reaching real impact, and what separates teams that talk about sustainability from teams that actually deliver it.

The Complete Guide to Building Sustainable IT Through Sequential Transformation

The fight for a more sustainable world can be challenging. As programmers, we love to break down challenging problems into more manageable, less intimidating steps.[^2] That’s exactly what this framework does—it transforms an existential crisis into actionable stages.

The statistics paint a sobering picture. Over 53.6 million tons of e-waste is produced globally, a 21% rise in just 5 years.[^1] Meanwhile, the ICT sector is responsible for between 1.8% and 3.9% of global greenhouse gas emissions[^3]—the primary driver of climate change. And here’s the kicker: by 2040, the information and communication technology sector will likely account for 14% of global carbon emissions.[^4]

But here’s what most people miss: knowing these numbers doesn’t change behavior. Research shows that organizational culture is among the main reasons for the failure of the implementation of corporate sustainability efforts and organizational change programs.[^5] You can’t skip steps and expect lasting change.

Step 1: Aware — Becoming Aware That There Is a Problem

Only once aware can people take the first step towards sustainable IT.[^2] This isn’t about guilt or shame—it’s about data and visibility.

When I say “aware,” I mean actively hunting for the truth in your systems. It’s running your first carbon footprint audit and discovering that your test environments run 24/7 burning energy for code nobody’s touched in months. It’s looking at your cloud bill and realizing you’re paying for storage you forgot existed three years ago.

Key elements that make awareness different from casual concern:

• You engage with actual data, not assumptions about your environmental impact
• You measure your footprint using credible tools and methodologies
• You identify where energy usage, waste production, and supply chain issues hide in your stack

Awareness is the catalyst for action. Without it, problems remain unseen, and opportunities are lost.[^2] The harsh reality? Most organizations think they’re aware when they’re really just informed. Being informed means you’ve read an article. Being aware means you’ve looked at your own metrics and can’t unsee what you’ve found.

The moment awareness truly lands is uncomfortable. It’s realizing that your microservices architecture, while technically elegant, is burning carbon like a bonfire. It’s understanding that data centers account for about 1% of global energy use[^4], and yours is part of that total.

Step 2: Conscious — Identifying Places for Change Through Deep Reflection

Once aware, you can become conscious of issues and identify places for change.[^2] This is where most sustainability initiatives die.

Consciousness is different from awareness. Awareness says, “We have a problem.” Consciousness says, “I understand why this problem exists, how it connects to everything else, and what needs to change.”

Being conscious is about embracing sustainability as a core value. It’s more than just knowing the facts; it’s about reflecting deeply, aligning your decisions with long-term ecological and ethical goals.[^2] This is where systems thinking enters the picture.

When you’re conscious, you start connecting dots:

• Why that “quick fix” deployment process creates waste downstream
• How your CI/CD pipeline’s testing strategy impacts energy consumption at scale
• The relationship between code efficiency and the electricity required to run it

Research confirms this matters. Organizations require a comprehensive sustainability implementation framework to achieve sustainability, and transformation should be handled scientifically and sequentially.[^6] You can’t skip from “we should probably do something” to “let’s buy carbon offsets” without the deep work of consciousness.

Conscious action ensures your efforts are genuine and meaningful. Without it, initiatives risk being superficial or short-lived. Consciousness transforms sustainability from a checkbox into a driving force behind innovation and cultural change.[^2]

The signal you’re truly conscious? You stop treating sustainability as a project and start seeing it as a lens through which you evaluate every technical decision.

Step 3: Enabled — Obtaining the Knowledge and Skills to Make Change

Here’s where the rubber meets the road. Being enabled means having the tools, resources, skills, and support to put your sustainability goals into action. It’s about removing barriers and equipping yourself and your team with the capabilities to create lasting impact.[^2]

I’ve watched teams get stuck here more than anywhere else. They’re aware. They’re conscious. They’re motivated. But they don’t know how to actually refactor that monolithic application to be more energy-efficient. They don’t have the authority to change their cloud provider to one with better renewable energy commitments. They lack the frameworks to make sustainable choices when architecting new systems.

According to the International Energy Agency, global data centers’ consumption is estimated to be between 2% and 3% of the world’s electricity, and this could rise to over 1,000 terawatt-hours by 2030[^7]—equivalent to Japan’s entire electricity consumption. We need teams who know how to design and build differently.

Becoming enabled involves:

• Building capabilities: Learning green software principles, understanding carbon-aware computing, mastering energy-efficient coding practices
• Accessing tools: Implementing carbon tracking in your CI/CD pipeline, using profiling tools to identify energy-intensive code paths, adopting frameworks designed for efficiency
• Creating support systems: Establishing communities of practice, getting leadership buy-in for sustainable architecture decisions, building the business case for green infrastructure

A study published in the journal Electronics stated that refactoring code optimizes software energy efficiency and significantly saves energy, depending on the application.[^7] But you need to know how to refactor with efficiency in mind—that skill doesn’t appear through osmosis.

Without being enabled, even the best intentions stall. By becoming enabled, you build the capacity to move from vision to execution, ensuring sustainable practices are realistic and scalable.[^2]

Look for these indicators that your team is genuinely enabled: They can estimate the carbon impact of architectural decisions. They know which cloud regions run on renewable energy. They understand the trade-offs between performance optimization and energy efficiency. They have the tools to measure their progress.

Step 4: Empowered — Feeling As Though You Can Actually Make a Change

This is the destination that makes the journey worthwhile. Being empowered means taking ownership of your role as a changemaker. It’s about having the confidence, autonomy, and leadership to drive sustainable transformation.[^2]

Empowerment is psychological as much as practical. It’s the shift from “I wish someone would do something” to “I’m doing something, and here’s how you can join me.”

Research validates the importance of this final step. Studies show that institutionalized responsibility for sustainability was the strongest predictor of corporate sustainability initiatives, along with a top-down approach to implement corporate sustainability.[^8] But true empowerment happens when it’s not just top-down—when engineers, designers, and operations teams feel they have agency.

You know a team is empowered when:

• They innovate proactively: They propose sustainable alternatives without waiting for permission, suggesting energy-efficient architectures during design reviews
• They lead by example: Their code reviews include considerations for efficiency, their documentation explains the sustainability rationale behind technical choices
• They create momentum: They run internal workshops, contribute to open-source sustainability tools, share their learnings publicly

Empowerment amplifies impact. When you’re empowered, you don’t just act—you lead. You create a ripple effect, motivating others to join the effort and accelerating the adoption of sustainable IT practices.[^2]

The most empowered teams I’ve worked with don’t wait for perfect conditions. They start where they are. They experiment. They measure. They share what they learn. They understand that sustainable change requires genuine emotional buy-in, not just temporary operational changes.[^9]

One team I worked with started by simply turning off their staging environments outside business hours. Small change. But they measured the impact, socialized the results, and suddenly other teams wanted in. That’s empowerment in action—creating change that spreads organically because people see it working.

Making This Work for You

Let’s get practical. Here’s how to use this framework in your organization:

Step 1: Start with honest measurement
You can’t manage what you don’t measure. Implement carbon tracking tools for your applications and infrastructure. If all U.S. servers met Energy Star standards, $1 billion in energy costs and 8.2 megatons of greenhouse gas emissions would be avoided yearly.[^4] The first step is knowing where you stand.

Step 2: Create space for reflection
Schedule dedicated time for your team to discuss sustainability—not as a nice-to-have, but as a core part of technical decision-making. Only an organizational culture that welcomes, embraces, and facilitates change and includes it in its organizational values and beliefs can promote sustainability.[^5] Make it part of your culture through deliberate practice.

Step 3: Invest in capability building
Training isn’t optional. Your team needs specific skills to make sustainable choices. Consider certifications in green software engineering, workshops on energy-efficient architecture, and hands-on practice with carbon tracking tools. Project success involves preparing the organization for transformation, ensuring stakeholder buy-in, and engaging executive sponsors to champion the change.[^10]

Step 4: Celebrate and amplify wins
When someone makes a sustainability improvement—even a small one—make noise about it. Recognition fuels empowerment. When individuals have an opportunity to shape a change, they are significantly more likely to embrace it.[^9] Give your team ownership and watch what happens.

The crucial insight? You can’t skip steps. Only once aware can people take the first step towards sustainable IT. Only once conscious to the issues can you identify effective areas for change.[^2] Each step builds on the previous one.

Start by getting aware. Really aware. Not “I read a blog post” aware, but “I know exactly how much energy my application consumes” aware. From there, the path forward reveals itself.

Key Takeaways

• The four steps of sustainable IT transformation—Aware, Conscious, Enabled, Empowered—create a sequential path from knowledge to lasting action
• Most organizations plateau at awareness or consciousness, never building the capabilities (enabled) or confidence (empowered) to create real change
• Sustainability transformation requires building organizational culture that embraces change as a core value, not a temporary initiative
• Measurement and visibility are non-negotiable—you need data about your actual environmental impact before you can improve it
