Carbon Footprint & Transition Plan
Do you have an action plan that addresses all of your environmental impacts and can be broken down into concrete actions?
We support you in rigorously measuring your environmental impacts and work with you to develop a transition plan grounded in science and tailored to the specific challenges of your industry.
As a leader and pioneer in decarbonization, our approach draws on the experience we’ve gained working with hundreds of private and public sector organizations to provide expert, tailored support.
BACKGROUND
What frameworks and standards do you use to measure your environmental impacts to ensure their reliability?
Between 2019 and 2023, the number of companies reporting their Scope 1, 2, and 3 emissions to the Carbon Disclosure Project increased significantly, from approximately 8,000 to more than 23,000 organizations.
This trend confirms that measuring and reporting one’s carbon footprint is no longer an option, but a necessity for maintaining credibility with customers, investors, and local stakeholders.
The question is no longer whether we should take action, but rather on which areas to focus our efforts.
