Stockholm Environment Institute released the 2025 Integrated Guide for Business GHG and Air Pollutant Emission Assessment, an update to its 2022 Practical Guide. The guide helps companies measure both greenhouse gases and local air pollutants in one framework, covering scope 1, 2, and 3 emissions alongside pollutants like PM and NOx. It targets businesses, cities, and supply chain managers who need consistent reporting across climate and air quality goals. The update reflects recent standards and adds practical steps for integrating air pollutant data with carbon accounting. It is useful for firms facing both net-zero targets and local clean air regulations. The guide is available on SEI's website and aligns with short-lived climate pollutant strategies.
