Keeping up with changing environmental policies and regulations across the globe can be daunting. In-house counsel's challenge of advising business based on those changes is what led Houston-based Lex Mundi, along with its international partners, to create the Lex Mundi Global Climate Change Law Guide.

The free guide, made available on Tuesday, allows in-house counsel to look up environmental regulations, greenhouse gas emission trading schemes, energy efficiency measures, renewable energy sources, financial institutional measures and prominent litigation worldwide. It also allows users to create a custom side-by-side report comparing different jurisdictions to help guide business decisions.

"Most jurisdictions do have some long-term measures in places to reduce emissions," Lauren Smith, international business development manager at Lex Mundi, said. "That's why we developed this for in-house counsel. So they can be aware and do some risk mitigation analysis with outside counsel before committing to business decisions."
