A NEW POLICY CLIMATE
THE SEARCH FOR NEW OPPORTUNITIES 1. Where are the main carbon stores? 3. Can we plug carbon hotspots? 2. Which areas are most suitable for afforestation? 4. And prevent new ones? 5. Can we find unsaturated carbon sinks in grassland?
NEW OPPORTUNITIES 1: PEATS
NEW OPPORTUNITIES 2: FARM AFFORESTATION
