System of Rice Intensification

Food

SRI is a holistic approach to sustainable rice cultivation. It improves soil, lowers inputs of seeds and water, and increases yields, while reducing emissions.

System of Rice Intensification

Reduced CO2: 3 gigatons
Net operational savings: $677.83 billion
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:

SRI has been adopted largely by smallholder farmers and has much higher yield benefits compared to improved rice production. We calculate that SRI can expand from 8.4 million acres to 133 million acres by 2050, both sequestering carbon and avoiding methane emissions that together total 3.1 gigatons of carbon dioxide or its equivalent over thirty years. With increased yields, 477 million additional tons of rice could be produced, earning farmers an additional $678 billion in pro t by 2050.

Retrofitting

Buildings and Cities

Up to 80 percent of the energy buildings consume is wasted. Retrofitting them can address waste through efficient insulation, heating and cooling systems, and lighting.

SAVINGS (billions US $)

Net savings by 2050

Impact:

As with net zero buildings, there are no results presented from our models here. Building owners who retrofit existing residential and commercial building space install better insulation, improved heating and cooling equipment, upgraded management systems, etc. These solutions are accounted for individually. No retrofit will look exactly the same, making forecasting costs and savings nearly impossible.
