    Royal Dutch Shell is launching a $ 300 million and forestry program, at a time when an increasing number of oil companies are putting money in carbon offset (碳补偿)plans to meet climate goals. The company will spend the money over the next three years on projects to store carbon, including large forests in the Netherlands and Spain, and will start offering motorists the option of purchasing carbon offsets when they buy petrol at the pump.

The executives of the company explained that these carbon offset projects were a new business opportunity for Shell, as well as a way to meet its climate targets. “We believe that over time we will be building a business, because these carbon credits will become more valuable as carbon becomes more limited," they said. Shell recently decided to cut its net carbon footprint (碳排放)by 2-3 percent in five years, which includes emissions (排放)from the products it sells. The company plans to produce carbon credits from the forestry projects, then sell these credits on to customers buying its oil and gas products, or apply the credits to its own operations to lower its carbon footprint.

Plants absorb carbon dioxide as they grow and restoring forests and other natural areas is considered one of the simplest ways to store carbon. However, the voluntary market for carbon credits based on forestry projects has its critics, as projects in developing countries can be hard to monitor. Shell's move has also been criticized by some environmentalists. They worried that there was a risk of " greenwash when companies invested in forestry projects. "There is an entire debate about whether forestry projects truly reduce emissions or not," they said, pointing out that planting in one area could cause deforestation (滥伐森林)to another.

Shell said it would rely on the third party to ensure its forest program to meet the Voluntary Carbon Standard and strict biodiversity requirements. Mark Lewis, head of climate change investment research at BNP Paribas, said, " Planting trees to offset emissions, as far as it goes, is a step in the right direction."
