Carbon Footprint Calculation

GHG Inventory Preparation for Companies

Scope 1, 2 & 3 GHG Inventory for Entities

Calculating your company’s Greenhouse Gas Inventory is an essential first step in managing your carbon footprint and an important part of your corporate sustainability program. The regulatory environment is changing rapidly in respect to GHG Inventory reporting. In the U.S., the SEC announced proposed requirements for the mandatory reporting of corporate GHG emissions and California introduced SB 253 to require reporting of GHG emissions. In the EU, the Corporate Sustainability Reporting Directive or CSRD will also affect companies with subsidiaries in the U.S. or companies doing business in the EU. Now is the time to make sure your entity GHG Inventory is in order whether you are a professional services company, a municipal entity, non-profit, or a product manufacturer large or small, private or public.
