Regulators, customers and investors are asking for emissions data. Here is who each rule applies to, what it requires, where it stands today and what Alpine delivers. Every one of them starts with the same foundation: an accurate, independently verified greenhouse gas (GHG) inventory.
Updated October 2026. Rules and deadlines change often. This page is a summary, not legal advice.
There is currently no federal climate disclosure regulation in force in the United States. The SEC's 2024 rule hasn't taken effect. California's laws are the ones that apply today, with more state rules to come.
Who: Companies with more than $1 billion in annual revenue that do business in California.
What: Annual public reporting of Scope 1 and 2 emissions, with Scope 3 starting in 2027 and independent assurance phasing in.
Status: The first Scope 1 and 2 reports are due November 10, 2026.
How we help: A complete Scope 1, 2 and 3 inventory built to the GHG Protocol and independently verified, so it is ready for assurance.
Who: Companies with more than $500 million in annual revenue that do business in California.
What: A climate-related financial risk report every two years, following the Task Force on Climate-related Financial Disclosures (TCFD) framework or an equivalent such as the International Sustainability Standards Board (ISSB) standards.
Status: A federal appeals court has paused enforcement while a legal challenge is decided. Reporting is voluntary for now, and the requirement returns if the court lifts the pause.
How we help: A TCFD-aligned climate risk report covering governance, strategy, risk management, and metrics and targets, ready to publish if the rule comes back into force.
Who: Large companies doing business in states considering similar laws.
What: New York's Senate passed a bill modeled on SB 253 in 2026, and New Jersey and Illinois have introduced similar bills.
Status: Pending in each state legislature.
How we help: An inventory built for California meets the standard these bills are modeled on, so you are ready if they pass.
The EU narrowed its Corporate Sustainability Reporting Directive (CSRD) in 2026. Far fewer companies report directly, but the ones that do still need emissions data from the companies they buy from.
Who: EU companies with more than 1,000 employees and more than €450 million in net turnover.
What: Sustainability reporting under the European Sustainability Reporting Standards (ESRS), including climate disclosures on emissions, targets and transition plans.
Status: First reports under the revised rules cover the 2027 financial year and are published in 2028.
How we help: The verified emissions inventory, science based targets and climate action plan behind the climate (E1) disclosures.
Who: Groups headquartered outside the EU with more than €450 million in EU net turnover and an EU subsidiary or branch with more than €200 million.
What: Group-level sustainability reporting under standards the EU is still finalizing.
Status: Reporting starts with the 2028 financial year, with first reports in 2029.
How we help: Start your inventory now, so you have several years of verified data in hand before your first report.
Who: Any company that sells to a business reporting under CSRD.
What: Requests for your emissions, targets and climate plans so your customers can complete their own reporting. Companies with fewer than 1,000 employees can limit what they share to the EU's voluntary SME standard, which still includes emissions.
How we help: A verified GHG inventory and published target that answer these requests once, in a form your customers trust.
UK rules have long focused on energy use and operational emissions. New standards based on the global ISSB framework are now available, and listed companies are moving first.
Who: Quoted companies, and large unquoted companies and LLPs.
What: Energy use, Scope 1 and 2 emissions, an intensity ratio and energy efficiency actions, reported in the annual report.
Status: In force since 2019. A 2026 government review recommended keeping it.
How we help: The energy and emissions data, intensity metrics and methodology statement SECR requires.
Who: Available to any UK company. Listed companies report against it on a comply-or-explain basis starting in 2027.
What: The UK versions of the ISSB's IFRS S1 and S2, covering Scope 1, 2 and 3 emissions and climate-related risks.
Status: Published in February 2026. The government is still consulting on wider use.
How we help: Verified Scope 1, 2 and 3 emissions and a climate risk report aligned with UK SRS S2.
For most technology companies, the first request comes from a customer or an investor, not a regulator.
Major brands report through CDP (formerly the Carbon Disclosure Project) and many ask their suppliers to respond too. We prepare the emissions data, targets and climate strategy behind a strong response.
Procurement teams use EcoVadis to score suppliers. Verified emissions data and a published target lift your environment score. Claravine doubled its score with Alpine.
More than 12,000 companies have set targets with the Science Based Targets initiative, and they expect their suppliers to follow. We take you from inventory to a validated target.
In one short call, we map which regulations and customer requests apply to your company, what data you already have, and the fastest path to verified, audit-ready results.
