Why disclose environmental data?

Action starts with disclosure.

All organizations – large and small – need to measure and understand their environmental risks, opportunities and impacts. Data surfaced through disclosure helps organizations take Earth-positive action and smart decisions to support their commercial interests. 

The value of disclosure data to the market is clear. It’s why hundreds of global multinational corporations and financial institutions with a quarter of all institutional assets ask CDP to collect the data they need.

Why disclose as a city?

Cities are the pivotal piece of the puzzle in tackling climate change – without them, action simply won’t be effective. Cities are responsible for over 70% of global carbon emissions, accounting for half of the world’s population and 80% of global GDP, making disclosure of environmental data by cities critical to ensuring action and accountability on climate and nature.

Report your climate change mitigation and adaptation risks, plans, actions and impact in a transparent manner for your communities, businesses and the wider world. In 2023, over 1,100 cities globally reported to CDP-ICLEI Track, gaining unparalleled insight on their progress towards climate leadership.

These include ICLEI, C40, WWF One Planet City Challenge and the Global Covenant of Mayors for Climate & Energy. You can also measure your progress against UN-backed climate campaigns such as Race to Zero. CDP-ICLEI Track streamlines your reporting experience through one questionnaire.

CHAMP is a commitment from national governments to strengthen collaboration with their subnational governments and to better integrate subnational climate actions in the planning, financing, implementation, and monitoring of climate strategies.

Why disclose as a state and region?

These include RegionsAdapt Initiative, Under2 Coalition and UN's Race to Resilience and Race to Zero, offering states and regions capacity-building opportunities and access to a network of relevant support.

These include cities, investors and companies. All data is uploaded to our Open Data Portal so you can compare and benchmark progress over time.

Data collated from cities, states and regions is central to informing policy and decision-making on the road to an Earth-positive economy. By reporting through CDP, your impact reaches far beyond the city boundaries and is used by entities such as the United Nations, the IPCC, and World Bank.

Why disclose as a public authority?

Public authorities and Crown corporations have a profound environmental and social impact, running critical systems used by millions of people each day, such as water, power, transportation, housing and waste management.

By working with CDP, public authorities have an unprecedented opportunity to advance sustainable infrastructure, bolster resilience and catalyze the transition to net zero. Recognizing the unique role and significance of public authorities, CDP offers a tailored approach to environmental disclosure to meet their needs.

Disclosure through CDP helps public authorities manage environmental impacts and risks, uncover opportunities, and benchmark against peers. Investors, regulators and customers seek to understand public authorities’ environmental risk exposure and direct and indirect contributions to the climate crisis. Through data transparency, public authorities can meet stakeholder expectations and align with best practices to mitigate risk and increase resiliency.

See ‘Meeting growing demand for disclosure’, above.

Disclosure demonstrates responsiveness to the expectations of capital markets, and signals sustainability leadership to potential investors. In some cases, disclosure and transparency can help lead to a lower cost of capital when borrowing. Reporting your pipeline of infrastructure and environmental projects through CDP’s questionnaire can help your organization attract climate finance. Public authorities are already making use of CDP’s sustainable infrastructure finance program, showcasing climate-positive and resiliency projects to the capital markets. Many public authorities are seeking financing for capital-intensive sustainability projects with immediate and long-term social impacts, such as reducing air pollution and increasing equity for vulnerable communities.

By working with CDP, public authorities have an unprecedented opportunity to advance sustainable infrastructure, bolster resilience and catalyze the transition to net-zero.
