Solutions:There is no silver bullet for the climate challenge that we face. The problem is enormous and deeply intertwined with our economic system, and there are many sources of greenhouse gasses(GHG). The only true solution is to reduce greenhouse gas in the atmosphere. There are two ways to do this: 1) reduce the amount of GHG released into the atmosphere. 2) Take GHG out of the atmosphere. Blockchain can be applied to both approaches.

There are many technological solutions that prevent carbon from entering the atmosphere. Most notably Small-scale home solar energy installations are greatly increasing solar energy capacity in California. This solar energy boom is a result of state and federal policy as well as technological advances in solar energy that makes solar energy in California cheaper than conventional energy. However, the major problem with solar energy is that installations only produce energy during the day when the sun is shining and the sun does not always shine when electricity is used. To solve this problem utility companies use smart grid technology to bill the customers by the net energy is produced and consumed by building. This is known as net energy metering (NEM), and is like a battery to the customer, except instead of using chemicals to store energy, the system uses the money, and credits accounts for energy put into the grid.

Regenerative Agriculture uses farming to pull carbon from the air and put it into the ground. The goal of regenerative agriculture is to fight climate change and habitat loss by increasing biomass and biodiversity(regenerationinternational.org). Regenerative Agriculture is promoted financially through certifications such as USDA Organic, Fair Trade and a handful of others, which offer the end consumer the ability to chose sustainably sourced products at a premium. Then that premium is paid to the producers to encourage sustainable practices. The issue with this is tracking the product from the shelves to the producer, especially when those producers are located on a different continent. Verifying such supply chains is a labor-intensive process that can involve dozens of independently verified bank transactions.
