The (net) emissions tokens network is a blockchain network for recording and trading the emissions from different channels such as the utility emissions channel, plus offsetting Renewable Energy Certificates and carbon offsets. Each token represents either an emissions debt, which you incur through activities that emit greenhouse gases, or an emissions credit, which offset the debt by removing emissions from the atmosphere.

To run the contract and integration tests, while hardhat is not otherwise running run:
npx hardhat test
NOTE about DB: the tests expect a Postgres DB named blockchain-carbon-accounting-test to exist (any data there will be wiped at the beginning of the tests).
If you need to set credentials for it, pass them as environment variables to the test runner: POSTGRES_USER=xxx POSTGRES_PASSWORD=xxx npx hardhat test
