Drawdown

Refrigerants, specifically CFCs and HCFCs, were once culprits in depleting the ozone layer, but they have been phased out. HFCs, the primary replacement, spare the ozone layer, but have 1,000 to 9,000 times greater capacity to warm the atmosphere than carbon dioxide.

A third of the food raised or prepared does not make it from farm or factory to fork. Producing uneaten food squanders  resources. The food we waste is responsible for roughly 8 percent of global emissions.

Research suggests silvopasture outpaces any grassland technique for counteracting Climate change. Pastures strewn or crisscrossed with trees sequester five to ten times as much carbon as those of the same size that are treeless, storing it in both biomass and soil.

Small-scale solar systems, typically sited on rooftops, accounted for roughly 30 percent of PV capacity installed worldwide in 2015. In Germany, a leader in solar, rooftops boast 1.5 million systems. In Bangladesh, population 157 million, more than 3.6 million home solar systems have been installed.

Regenerative agriculture enhances and sustains the health of the soil by restoring its carbon content, which in turn improves productivity.

• Windbreaks reduce erosion and create habitat for birds and pollinators.

• Fast-growing annuals, susceptible to being flattened by wind and rain, can be protected.

• Deep-rooted plants can draw up minerals and nutrients for shallow-rooted crops.
