I think number one is the closest one.

The GDP is calculated by using input-output models in OECD countries (all of these tables are available on OECD home page by countries). Each company belongs to an industrial sector, and the company's output contributes to the industry's output. Each sector has its row in the input-output matrix. All production outputs (rows) added together gives you the GDP. The matrix columns are the same sectors, but you can find their inputs there. So each cell shows you that the given column uses the given row's output as an input. These tables can be used in money term, but you can change it to CO2 emission if you are interested in that.

The important thing is that a sector outputs have an impact on all the other sectors. So if your company's production increases, it increases the production of other sectors (your company buy more feedstock and employs more people who buy more stuff). This multiplicator effect represented by economic multipliers. These multipliers are industry and region specific ones. For example, $1 increase in car manufacturing production results in $2.2 increase in the national economy, and one new job in the automotive industry results in 1.7 new jobs in the economy.

Put it in a nutshell, a company performance has a direct impact on the national economy (even larger than its own production), and the GDP impacts the company via the increasing or decreasing demand for its product.

If you are interested applying economic multipliers or input-output models, contact me, I am open to collaborating.
