Bioplastic

Materials

Ninety percent of plastics could be derived from plants instead of fossil fuels. Bioplastics can be biodegradable and often have lower emissions.

Bioplastic

Reduced CO2: 4 gigatons
Net cost (Billions US$): $19.15
What do these numbers mean?

TOTAL CO2-EQ REDUCTION (GT)

Total CO2-equivalent reduction in atmospheric greenhouse gases by 2050 (gigatons)

NET COST (billions US $)

Net cost to implement

SAVINGS (billions US $)

Net savings by 2050

Impact:

We estimate the total production of plastics to grow from 311 million tons in 2014 to at least 792 million tons by 2050. This is conservative, with other sources estimating over 1 billion tons if trends continue. We model the aggressive growth of bioplastics to capture 49 percent of the market by 2050, avoiding 4.3 gigatons of emissions. While technical potential is even higher, this solution is constrained by limited biomass feedstock available without additional land conversion. The cost to produce bioplastics in this scenario is $19 billion over thirty years. While the financial costs are currently higher for producers, they are dropping quickly.

Methane Digesters (Small)

Electricity Generation

At backyard- and farmyard-scale, anaerobic digesters are used to manage organic waste. They control methane emissions, while producing biogas (an energy source) and digestate (nutrient-rich fertilizer).

Methane Digesters (Small)

Reduced CO2: 2 gigatons
Net cost (Billions US$): $15.50
Net operational savings: $13.90 billion

SAVINGS (billions US $)

Net savings by 2050

Impact:

We project that by 2050, small digesters can replace 57.5 million inefficient cookstoves in low-income economies, resulting in 1.9 gigatons of carbon dioxide emissions avoided at a cost of $15.5 billion. If you couple this impact with that of large methane digesters, the cumulative result is 10.3 gigatons of carbon dioxide emissions avoided.
