Slow reductions=LESS CDR
I often see the argument that the more emissions remain the more CDR is needed. Example below
But it's the opposite! If a lot of emissions remain it means there wasn't enough political will & capital to address them. That will & capital won't magically appear for CDR instead

NEW ANALYSIS: What role will CDR play for shipping?
Biofuels, onboard CCS, and durable CDR are likely to be cheapest for the majority of emissions. But many roadmaps center around electrofuels, despite them looking like the most expensive alternative, as with aviation.

All emission reductions more expensive than DACCS are hard to abate.
That's the proposed definition in this new paper. I agree, and have been arguing for a long time that there is NO need to create a special list of residual emissions... 1/5

The CO2 removal industry is about to hit a milestone: 1 million tons of durable removals. But things are moving too slowly to reach gigaton scale on time. At Carbon Unbound summit last week things felt precarious. One person told me without more buyers the industry is in a “house of delusion.”
At this rate, carbon dioxide removal will never matter for the climate

I categorically disagree with claims that CO₂ removal (CDR) is a scam. The field is full of smart people dedicated to figuring out what, if anything, works, because we’ll need CDR in the future for legacy and residual emissions. Funding via market mechanisms isn’t ideal, but doesn’t make it a scam.

Planting trees in snow-covered regions is not a great climate solution. We already knew trees reflect less sunlight than snow, contributing to warming (although the effect is complex since forests increase clouds). This new study points to large carbon loss from frozen soils when planting trees

Can you visualize a Gt of CO₂?
RMI put together a great explainer. See the image for scale.
Some highlights:
1 Gt CDR per year would require CAPEX spending of $32B-$1.1T. Huge range, mostly due to rock-based solutions being capex low (but higher opex).
