Most people assume climate action will be expensive or disruptive. The carbon math shows the opposite. For the vast majority of everyday products, cleaning up the remaining emissions adds only about 2% to the price - a pattern first highlighted by Jens Burchardt at Boston Consulting Group in 2021 and confirmed again in updated lifecycle data today.

This brief explains why that small cost matters, how it fits into the broader climate system, and why permanent carbon removal is the backstop, not the alternative. We still reduce emissions wherever possible - because reductions are usually cheaper and faster - and use permanent removal only for the residual emissions we can’t eliminate.

You’ll find a clear explanation of the “atmospheric bathtub,” examples of past environmental upgrades that followed the same small‑cost/large‑benefit pattern, and transparent carbon math for dozens of everyday products.

When people understand the true cost of climate action, support rises. This report makes that understanding intuitive, evidence‑based, and accessible.

Most countries have only half the toolkit.  This report shows what the other half is worth.

Opening all climate-aligned pathways - efficiency, electrification, fuel switching, carbon capture, and permanent carbon dioxide removal - dramatically lowers the cost of reaching net zero. Today, most governments have activated only part of the available toolkit. Permanent CDR pathways are allowed in principle but unavailable in practice in most jurisdictions, because recognized standards do not yet exist. Without those standards, governments cannot procure permanent removals, innovators cannot access stable demand, and taxpayers end up paying more for a restricted set of options. In many jurisdictions, that premium is two to three times the cost of the lowest available alternative.

This report shows how recognizing all science-aligned pathways could save governments billions annually in procurement costs, unlock trillions in avoided costs across hard-to-abate sectors globally, and accelerate net zero progress - all without additional government spending. It is a standards decision, not a spending decision.

Understanding global emissions can feel abstract.  We hear about sectors, industries, and national inventories, but we experience emissions through the food we eat, the homes we live in, the things we buy, and the ways we move through the world. This report reframes global greenhouse gas emissions through a consumption‑side lens, helping us see where emissions actually show up in daily life and where our choices and signals can have the greatest impact.

Using the latest global data, we map emissions from their production‑side sources (like energy, industry, and agriculture) to the consumption‑side categories where they appear in our lives. This approach reveals powerful insights, including why food is one of the largest drivers of global emissions, why passenger travel dominates the transport footprint, and how more than 40 billion tonnes of emissions flow through the goods, services, and systems we rely on every day.

This framework is foundational to our work at Possible by Design. It helps identify high‑impact personal actions, highlights where shared systems shape our choices, and guides the development of upcoming Research & Insights deep dives, and Advocacy pathways.

Requiring climate‑footprint labels on products could drive significant global emissions reductions. This analysis outlines the mechanism, the evidence, and the potential impact.

Climate‑footprint labels make the climate impact of everyday products visible at the point of choice - and that simple shift unlocks one of the largest, lowest‑cost emissions reductions available today. Four consumption categories shaped directly by product‑level transparency account for 61% of global emissions, and these are precisely the sectors where labeling reliably drives producer reformulation, supply‑chain cleanup, and meaningful consumer shifts.

Using conservative, sector‑specific assumptions grounded in decades of evidence from nutrition labels, EU energy labels, and fuel‑economy standards, our analysis finds that mandatory climate‑footprint labels could reduce global emissions by 1–5 gigatonnes of CO₂e per year, with a central estimate of ~3 Gt - roughly equivalent to the annual emissions of the European Union.

The mechanism is straightforward:

• Producers clean up supply chains, delivering over 1 Gt/year

• Small shifts in food choices add 0.6–1.2 Gt/year

• Freight, packaging, and materials optimization adds ~0.9 Gt/year

• Waste and leakage reductions add ~0.2 Gt/year

Climate‑footprint labels are not a new idea — they are the next step in a global transparency tradition that has already transformed markets for nutrition, energy use, and vehicle efficiency. As major economies move toward carbon‑transparent supply chains, climate‑footprint labels offer a practical, scalable, and low‑cost tool for accelerating decarbonization worldwide.
