This post clearly outlines a methodology for carbon accounting to support effective calculation and control of greenhouse gas emissions by organizations. Firstly, it defines the organizational boundaries and identifies sources of emissions in three scopes: direct, indirect, and supply chain emissions. The methodology focuses substantially on systematic data collection as well as relevant application of emission factors to all entities with consequent calculation of the total carbon footprint in CO2e. Additionally, it requires that reduction targets are brought down, continued tracking and reporting, as well as stakeholder engagement, meaning that companies need to meet their compliance in addition to becoming better at enhancing their efforts towards sustainability. By so doing, companies will be able to make systematic contributions to mitigating climate change while furthering environmental responsibility.
