We need to slash greenhouse-gas emissions while supporting activities that remove greenhouse gasses from the atmosphere, and carbon markets can both accelerate reductions and ramp up removals. Why, then, is the debate so contentious? For answers, I turned to Eli-Mitchell Larson, a self-proclaimed “Carbon Removal Evangelist” who's helping to build up Carbon Removal Advocacy Europe (CRAE). We had a long and fruitful discussion that I think serves as a sort of reductions and removals 101.
