CAPEX (Capital Expenditure) refers to the funds a company invests in acquiring, upgrading, or maintaining long-term assets such as buildings, machinery, technology, or infrastructure. These are not regular operating costs—they’re strategic investments aimed at enhancing future productivity or capacity.
Typical examples include:
Purchasing new equipment or vehicles
Constructing or renovating buildings
Upgrading IT systems or software
Expanding production facilities
Developing renewable energy infrastructure
CAPEX is capitalized on the balance sheet and amortized or depreciated over time, unlike OPEX (Operating Expenditure) which is expensed immediately.
Signals growth: High CAPEX often indicates expansion or innovation.
Impacts cash flow: It reduces short-term liquidity but can boost long-term returns.
Used in valuation: CAPEX affects metrics like Free Cash Flow (FCF), which investors use to assess company value.
Formula for estimating CAPEX:
CAPEX = PP&E (current year) – PP&E (previous year) + Depreciation
Where PP&E = Property, Plant & Equipment.
In climate and carbon removal contexts, CAPEX is crucial for:
Building mass timber structures (carbon storage)
Installing direct air capture systems
Developing biochar production facilities
Certifying projects under frameworks like CRCF
These investments often qualify for removal credits, which are priced at a premium due to their long-term climate impact.
