Our Environmental Law Experience

Experts in air pollution, energy & climate change

Our attorneys have influenced the major air and energy issues for 40 years. Ayres Law Group uses its extensive experience in the legislative, administrative and federal judicial process to solve clients’ problems.

Comprehensive representation

We help clients design comprehensive strategies to achieve their goals as efficiently as possible. This includes identifying various avenues to resolve their problems, sometimes operating across all three branches of government, or at the state level. We help clients identify and reach the critical decision-makers on their particular problems.

Regulatory assistance

We have deep experience working with federal environmental agencies through the regulatory process. We help shape regulations on clients’ behalf and assist with navigating the regulatory maze. We advise clients on compliance issues and solutions and advocate for their interests with the EPA.

Legislative solutions

Over the past 40 years our attorneys have been instrumental in shaping environmental legislation at the state, national and international levels. We draft legislative language to fit our clients’ needs and find the right vehicle for getting it done. We have relationships with the key policymakers in numerous institutions in Washington and the states and can help clients ensure that their concerns are being heard.

Internationally, we have significant experience working with foreign governments on air quality and energy laws, including advising China's environmental agency regarding revisions to the Chinese air pollution law. We also assist clients with furthering their interests under international agreements by influencing the domestic policy process at home.

We are experienced appellate litigators and have been involved in dozens of the nation’s most important cases interpreting the Clean Air Act. Notable cases include a challenge to the EPA's Clean Power Plan limiting greenhouse gas emissions from power plants; Massachusetts v.
