Ford Motor Co. and rival General Motors are engaged in a PR battle to publicize their commitments to responsible corporate behavior.
Ford has published ``corporate citizenship'' reports for the past two years detailing issues such as the challenge of reconciling the booming sale of its gas-hogging sport utility vehicles with chairman William Clay Ford Jr.'s goal of improving the environment. Ford says it is also reevaluating its products and manufacturing operations in light of its declaration that global warming is a major problem.
