The document proposes three initiatives to improve waste management and increase carbon sinks in Madrid, Spain. The first proposes a public-private partnership called "+Verde" to reduce tree maintenance costs. The second proposes a biodiesel production initiative using recycled cooking oil to fuel public transportation. The third proposes increasing the municipality's social media presence to improve awareness campaigns in a more cost-effective manner.

4. Carbon Sinks Ability to absorb up to 20 tons of CO2/hectare/year (Ayuntamiento de Madrid, 2008) Ability to save up to 10% of energy usage around buildings (Trees for Cities, 2011) Adaptation measure: reducing urban heat island effect
5. Current Situation High maintenance cost of trees High percentage of citizens not recycling used cooking oil Municipality of Madrid not being present on social media
