Environmental and Climate Change

In a world increasingly defined by environmental challenges and climate crises, Ally Law member firms provide comprehensive legal solutions.

Global Overview

While the highest-profile impacts of environmental and climate change may appear local, the forces driving these issues are global. In response, governments, business leaders and communities are re-envisioning their approaches to these challenges. This momentum is leading to a broad range of international agreements and domestic laws and regulations that require effective compliance strategies. At the same time, organizations of all sizes and across industries are discovering — and commercializing — new technologies and adaptive solutions to meet these demands head on.

At Ally Law, our member firms understand the urgency and complexity of these matters and are dedicated to delivering results that benefit our clients and the planet. For more information about Ally Law’s network-wide initiatives, please visit our Your Sustainable Ally page.

The Ally Law Advantage

Environmental and climate-change issues do not exist in a vacuum — rather, they require comprehensive, collaborative effort. Working with lawyers from across our member firms, we provide coordinated counsel on the full spectrum of environmental regulations and compliance. When local, national and cross-border disputes arise, we draw on the skills of experienced litigators to provide effective, solution-focused representation in court, before government agencies, and in arbitration and mediation.

Among other key benefits, we help clients:

  • Mitigate risks, reducing the likelihood of costly legal battles.
  • Gain strategic advantage, by positioning themselves as leaders in sustainability and attracting environmentally conscious investors and customers.
  • Reduce expenditures, by avoiding financial setbacks associated with environmental violations.
  • Capitalize on emerging opportunities in renewable energy, carbon markets, and sustainable business practices.

Our CLients

Ally Law member firms represent publicly traded and privately held corporations, government entities and non-governmental organizations (NGOs), public-private partnerships and consortia and individuals. A number of our clients operate in highly scrutinized industries subject to significant regulatory oversight, such as energy, manufacturing, mining, natural resources, transportation and distribution. Others are focused on research into and development and deployment of solutions to environmental and climate-change challenges. Many — if not most — are engaged in both.
