Addressing Environmental Sustainability for Business (Part 1) The appointment by President Duterte of Gina Lopez, a well-known advocate of environmental sustainability, as Secretary of the Department of Environment and Natural Resources (DENR), should be taken as an opportunity by business people to take a hard and close look at their ability to incorporate the protection of the environment into the very core of their corporate strategy. Protection of the environment should no longer be an after thought or worse, just a PR ploy of companies operating in the Philippines and for that matter in the entire ASEAN region in which there are many challenges to environmental sustainability, especially in mining, agribusiness, and power plants.
