Climate change is happening and is caused by human activity. The scientific consensus is that global temperatures have risen significantly since the industrial revolution and the levels of CO2 in the atmosphere are the highest they have been in at least 650,000 years. If emissions continue unabated, global temperatures could rise by 2-5 degrees Celsius by 2100, causing widespread impacts. Business contributes significantly to greenhouse gas emissions and will be impacted by physical and regulatory changes resulting from climate change. Many companies are already taking action to reduce their carbon footprints and develop low-carbon technologies and solutions.
