Most climate communication focuses on the problem, or the urgency. This framework does something different: it shows the complete logical chain from diagnosis to outcome - every foundation, every actor, every step. Without the whole picture, it's hard to know where you fit. With it, the path forward becomes real.

​​

1. THE PROBLEM: Breaching Planetary Boundaries Six of nine planetary guardrails transgressed. Climate is the most urgent, measurable, and tractable.

​​

Scientists have identified nine Planetary Boundaries - the conditions within which human civilization has always existed and thrived. Think of them as the guardrails of a habitable planet. Right now, we've pushed through six of them: climate, biodiversity, biogeochemical flows, and more.

 

Climate change is the most urgent and the most tractable. Fix it, and we also help bring some of the others back into safe territory.

​​

This isn't doom. It's diagnosis. And diagnosis is the beginning of treatment.

​

​​

2. TECHNICAL FEASIBILITY: We Have the Tools The solutions exist across every sector. This is a solvable engineering challenge, not an open question.

​

Across every sector of the global economy - energy, transport, buildings, industry, food, land use - solutions exist to reduce emissions as far as technically possible. Most are already deployed at scale somewhere in the world. Many are already cheaper than the high-carbon alternatives they replace.

 

The final 10–15% - the hard-to-abate remainder that can't yet be eliminated at source - requires permanent Carbon Dioxide Removal: technology that pulls CO₂ from the atmosphere and stores it permanently, whether deep underground, in minerals, in the ocean, or through other science-aligned pathways. Permanent CDR exists, is scaling, and its costs are falling along a familiar innovation curve.

 

About 81% of global emissions serve personal consumption - food, transport, home energy, products. These emissions are embedded in the prices of the things we buy. Producers emit on our behalf; consumers drive demand without visibility. Understanding this is the key to designing solutions that actually work. It also means this isn't only an industrial problem. That's actually good news: it means the solutions live in the same systems that shape our everyday choices.

​

​

3. ECONOMIC FEASIBILITY: We Can Afford It About 2% more for most products. ~4.5% of GDP/yr. Not a moonshot - a budgeting choice.

​

The barrier to solving climate change isn't money. It's alignment.

​

Across five years of Carbonomics analysis and multiple independent cost curves, the conclusion is consistent: we can abate almost everything with existing technologies at manageable cost. The total cost of getting to Geological Net Zero (“Geo Zero”) - doing our best to reduce emissions across every sector, and permanently removing what remains - is approximately 4.5% of global GDP per year. That's comparable to past transformations like electrification, sanitation, and the internet. Well within the range of today's discretionary spending. And far lower than the cost of inaction.

 

At the product level, the picture is equally clear. A cup of coffee: about 2.7% more. A laptop: about 2.4% more. A pint of beer: about 1% more. For most everyday products, the cost of making them completely clean is in the range of 1–3%.

​

Capital is ready. Pension funds, patient investors, and infrastructure financiers are waiting for the policy signals that de-risk the market and connect them to the demand that net zero law has already created. The money isn't the constraint. The plumbing is.

​

​

4. SOCIAL FEASIBILITY: The Will Is Already There A silent supermajority already supports meaningful action. The bridge doesn't need to build public support - it needs to make it visible.

​

Here's something that might surprise you: the majority of people in most countries already support meaningful climate action. You are almost certainly not alone. Your neighbours probably care. The person ahead of you in the grocery line probably cares.

​

So why does it feel like nobody is doing anything?

​

Because caring privately and acting visibly are different things. When the majority stays quiet, even a vocal minority can convince governments that the public is indifferent. Action stalls. Everyone waits for everyone else to go first.

​

Social scientists have found that when just 3.5% of a population participates visibly, systems shift - not just from pressure, but because visible participation corrects the signal politicians receive. It shows them what's actually safe to do.

​

The bridge doesn't need to manufacture support that doesn't exist. It needs to make the support that already exists legible - to the people who hold it, to each other, and to the decision-makers who are waiting for permission to act.

​

Possible by Design is working to make that supermajority visible to itself.

​

​

5. THE TARGET - GEOLOGICAL NET ZERO: Planetary Boundaries Test Every tonne released from the geosphere must be locked away. No shortcuts.

​

"Net zero" is an accounting term. Geological Net Zero is a physical reality.

​

Every tonne of CO₂ released from geological storage - fossil fuels buried deep underground for millennia - must eventually be permanently locked away. Think of it like a carbon ledger that must physically balance, not just on paper. Forests and soils matter enormously for many reasons, but they can't serve as the permanent disposal system for fossil carbon. We have to build the disposal infrastructure - the good news is it exists and can be scaled.

​

Equally important: solutions must not solve one boundary problem by breaking another. Water, land, biodiversity, nitrogen - these all count. The Planetary Boundaries framework ensures we solve climate in a way that keeps the whole system safe. That's the standard. It rules out shortcuts, and it points toward the most elegant solutions.

​

​

6. THE OUTCOME: Living Well in a Sustainable World Geological Net Zero. People living well. Planetary boundaries trending back toward safe space.

​

A complete solution requires every actor in the system: scientists refining the boundaries, builders deploying solutions at speed and scale, producers competing on decarbonization, governments setting the ramp and opening all pathways, and the rest of us making visible choices, demanding the policy, and holding the line.

​

Each role is active. Each role is necessary. No one has to do everything - but everyone has a role, and the Milestone Map shows exactly what it is.

​

When every emission carries the full cost of responsible disposal, Geological Net Zero is reached. We begin to draw down the excess CO₂ in the atmosphere rather than adding to it. The clean economy turns out to be quieter, healthier, and in many cases less expensive than the one it replaced - not because people sacrificed, but because good design won. What we take, make, and waste stays in harmony with what the earth can replenish, restore, and renew.

​

This is what it looks like to return to the safe operating space. Starting with climate. And propagating outward.
