We need global agreements and long term global goals to guide the action. The private sector must take responsibility as well. I am happy to note that more and more business leaders recognize that they have a responsibility for the health and safety of their employees, (and the employees of their subcontractors) and for the environment both at home and abroad. And it has become something of a "must” for business to demonstrate responsibility for their CG> emissions, Airlines are selling CO2 compensation, oil companies are going into renewable energy, the construction industry is moving towards low energy houses and car manufacturers are marketing more environmentally friendly cars.
