While the Environmental Protection Agency (“EPA”) is proposing to amend the federal Greenhouse Gas Reporting Program (“GHGRP”) to remove reporting requirements for nearly all sources, it remains important for companies to track developments and manage their compliance obligations with existing and emerging state GHG reporting programs.  Several states, such as…

On June 23, 2025 the Council of the EU, which represents the 27 EU Member States, agreed on its negotiating mandate for the Corporate Sustainability Reporting Directive (“CSRD”) and Corporate Sustainability Due Diligence Directive (“CSDDD”) omnibus simplification.

This follows the European Commission’s omnibus proposal from February and is the next…

After its 12-month deferral, the EU’s Deforestation Regulation (“EUDR”) is set to apply from December 30, 2025.  Many companies are therefore refocusing EUDR compliance efforts. This blog provides an update on the rules and guidance and key, practical takeaways for companies.

The European Commission (“Commission”) recently provided new and updated…

On May 28, the Biden-Harris Administration issued the Voluntary Carbon Markets Joint Policy Statement and Principles (Policy Statement).  You can find Covington’s analysis of the Policy Statement here.  Jointly announced by the U.S. Secretaries of Treasury, Agriculture, and Energy, and senior White House climate officials, the Policy Statement describes a three-pronged approach to responsible carbon market development and participation: (1) credit or supply integrity, including protections regarding climate and environmental justice; (2) demand integrity, to ensure the credible use of credits; and (3) market-level integrity, including facilitating efficient market participation and lowering transaction costs.  The Policy Statement builds on other recent federal actions, including the Commodities Futures Trading Commission’s 2023 proposed guidance for voluntary carbon credit derivatives and the Securities and Exchange Commission’s final climate risk disclosure rule, which requires certain disclosures related to carbon offset purchases, in the Administration’s attention to and elevation of the voluntary carbon market as an important element in the nation’s climate policy. 

In this post, we dive deeper into the voluntary carbon market landscape, implications for business, and additional recent developments. Continue Reading Engaging in Voluntary Carbon Markets: Overview of Key Developments, Risks, and Opportunities

In the early hours of December 14, 2023, the Council of the EU (“Council”) and the European Parliament (“Parliament”) reached a provisional political agreement on the Corporate Sustainability Due Diligence Directive (“CSDDD”). Described as a “historic breakthrough” by Lara Wolters, who has led this file for the Parliament, the CSDDD will require many companies in the EU and beyond to conduct environmental and human rights due diligence on their global operations and value chain, and oblige them to adopt a transition plan for climate change mitigation.

Given the CSDDD’s relevance for companies’ ongoing compliance planning on environmental and human rights matters, this blog aims to advise clients on the basic elements of the CSDDD agreement based on press releases from the Council, Parliament, and the European Commission (“Commission”), even if much uncertainty remains. Although a political agreement has been reached, the text of the agreement is not publicly available and a number of details of the legal text will need to be finalized in follow-up technical meetings. Covington will publish a more detailed alert on “how to prepare” for the CSDDD once the full text is available (likely in early 2024).Continue Reading Provisional Agreement on the EU’s Corporate Sustainability Due Diligence Directive (CSDDD): Key Elements of the Deal

What You Need to Know.

  • After two days of intense negotiations, world leaders adopted a draft decision that sets out international climate priorities in response to the findings of the first Global Stocktake under the Paris Agreement.  The decision covers several thematic areas, including mitigation of greenhouse gas emissions, adaptation and resilience in the face of climate change, financing and means of implementation and support for climate projects, and loss and damage funding for climate-vulnerable nations.  The text of the draft decision can be found on the UNFCCC’s website here.

What You Need to Know.

  • Azerbaijan is poised to host COP29 next year after receiving regional backing.  If formally confirmed, Azerbaijan’s COP Presidency would resolve months of deadlock.  It will also trigger criticism that next year’s COP will again be hosted by a nation heavily dependent on fossil fuel exports.

What You Need to Know.

  • The UNFCCC has released a draft text of the negotiated outcome of the first Global Stocktake under the Paris Agreement.  The draft text currently includes four options to address the question of “phasing out” versus “phasing down” the use of fossil fuels, with the strongest option’s wording being “[a] phase out of fossil fuels in line with best available science.”  Options with weaker wording would call on the Parties to the Paris Agreement to take action towards “phasing out unabated fossil fuels and to rapidly reducing their use so as to achieve net-zero CO2 in energy systems by or around mid-century.”

What You Need to Know. 

  • “We very much believe and respect the science,” said COP28 President Al Jaber on Monday after it had been reported that he had earlier commented that there was “no science” behind requiring the phase-out of fossil fuels to limit global warming to 1.5C. President Al Jaber went on to say that “the phase down and the phase out of fossil fuel is inevitable.”  This statement comes after heavy criticism from climate activists and scientists of President Al Jaber’s earlier comments, further emphasizing the centrality of the “phase down” vs. “phase out” debate as a wedge issue at this COP.

Laws and regulations that require companies, both private and public, to disclose their greenhouse gas (GHG) emissions continue to expand in the European Union and in the United States.  Under the EU Corporate Sustainability Reporting Directive (CSRD), beginning in 2025, EU-based public companies and large EU-based private companies will be required to report all material Scope 1, 2, and 3 GHG emissions as set forth in the European Sustainability Reporting Standards.  In the United States, California recently passed landmark climate-related disclosure legislation that will require U.S. companies that do business in California and have greater than $1 billion in annual revenues to file annual reports publicly disclosing their Scope 1 and 2 GHG emissions beginning in 2026 and Scope 3 GHG emissions in 2027.  This legislation is expected to be joined by the U.S. Securities and Exchange Commission’s (SEC) proposed climate-related disclosure rule.  Initially proposed in March 2022, if finalized, the SEC rule would require public companies to disclose their Scope 1 and Scope 2 emissions and material Scope 3 emissions.  And later this year, world policymakers, activists, and business leaders will convene at COP28 to discuss global progress towards achieving the net-zero GHG emissions targets set by the Paris Agreement.

The Greenhouse Gas Protocol (GHG Protocol) sits at the center of all these efforts.  Established by the World Resources Institute and the World Business Counsel for Sustainable Development in 2001, the GHG Protocol establishes comprehensive standards for private and public entities to calculate and report their GHG emissions and track progress towards their emissions targets.
