Large businesses in California will have to disclose a wide range of planet-warming emissions under a new law Gov. Gavin Newsom signed Saturday — the most sweeping mandate of its kind in the nation.

The law requires more than 5,300 companies that operate in California and make more than $1 billion in annual revenues to report both their direct and indirect emissions. That includes things like emissions from operating a building or store as well as those from activities like employee business travel and transporting their products.

The law will bring more transparency to the public about how big businesses contribute to climate change, and it could nudge them to evaluate how they can reduce their emissions, advocates say. They argue many businesses already disclose some of their emissions to the state.

    There are a lot of internationally recognized calculations and reporting methods and companies can hire consultants who can estimate the emissions in their end to end supply chains.

    There are also calculators online that can give an example on what elements are considered, e.g. the below from UN.
