What a global warming potential value is — and why it changes
In short: A global warming potential (GWP) value converts any greenhouse gas into an equivalent amount of CO₂, so different gases can be added together into a single tons CO₂e figure. The value changes because IPCC assessment reports revise it as atmospheric chemistry modelling improves — and because the answer depends on whether you use […]
The average carbon footprint per American: what the data actually shows
The average carbon footprint per American sits at roughly 14–16 metric tons of CO₂ per person per year. That places the US among the highest per-capita emitters in the world — about three times the global average, and roughly twice the EU average. This article explains where that number comes from, what drives it, and […]
